The experience of playing model aircraft

I am the Son of Heaven 30 oil machine to start, like all novice alike, eager to fly their love machine up, like all newcomers, like the first flight bombing. See mold faithful casual ease to fly, share their own, the joy, deeply envious, and then look at their bad technique, dismember the big paddle, once lost confidence, only mentioning machine go home, secretly trouble . After the experience of this forum to seriously study the theoretical knowledge and the vast majority of the Friends of Mount decided to stop and take practice simulator, after the first virtual reality. Practice the process is a learning process, just like a student learning the same lessons, theory and practice, repeated practice, and finally work pays off, now finally stepped into the threshold of model aircraft, model aircraft passed since that is the first entry a clearance. Here are some personal experience:

1. The correct treatment model aircraft, the mentality is extremely heavy
Motivation everyone into the mold are not the same, some to round childhood dreams, some to amateur entertainment, but also some in order to exercise, there is to make more friends. As the majority of the Friends said the same mold, model aircraft are not toys, model aircraft activities precisely, is a sport, by HM we can exercise their ability to respond to emergency response and increase the flexibility of the fingers to stimulate the central nervous strengthen operations highly concentrated the attention of those who can, set workout entertainment, relax in order to achieve the purpose. Different from other sports, HM obtain a certain degree of risk, not only hurt themselves, but also may hurt others.
Two, solid theoretical basis to understand the principle of transfer machines
2. Step by step, from the virtual into the real
As the saying goes, haste makes waste! Hover each side must honestly practice. As a friend said the forum as: Analog is king! The economic conditions are not well-off or pipe borne his wife's friends, the simulator is the best entry options. The greatest advantage of using the simulator is not mentally responsible, without limitation venues and transport, money and save time and effort! I use XTR, which has a very good exercise function, surrounded by hovering simulation exercises can be performed separately. From the beginning of the beginning of the tail to hover, hover got 10 minutes and does not blow up in a relatively small area and then into the general flight mode frog jump takeoff and landing practice, this process should be repeated constantly takeoff, landing, I got some time to have a qualitative leap, feeling each exercise ten minutes without bombing, and then aiming machine. Fax machines and simulators to practice the opposite order, first starting from the frog jump, then hover. Personal experience, this approach rarely practice bombing. After hovering tail clearance, practice head, head-to-tail exercise to practice the steps and the same. Exercise also began to rival the real machine from the frog jump, head off, head landed, some friends turned off after the end of the fuselage on the right track, this method is not recommended for individuals. Each side must start from the frog jump honestly, this advantage is quick, but do not panic if the wrong Tuo, a smooth landing on each side, to avoid unnecessary losses. Head and tailclearance, much easier on opposite sides, will soon get started.

3. Overcome difficulties, perseverance
HM and exercise, have a fresh period, tired period. Many of my friends had not practiced fresh of a fly, or even lose confidence. Excellent technology is built up bit by bit by the usual three days fishing, two days drying nets can not train good technology, even stuck in the front end instead of hovering over time has become tasteless, tasteless, gesture. Die faithful usually have busy working, busy studying, busy families, a week, taking a little time to practice is necessary, even if it is practiced simulator, try to participate in group activities, whether Which sport or activity, exercise at the same time , make friends, why should not a lot of exchange is a great pleasure in life?
4. Constantly sum up, enjoy the process
Every flight is very important to summarize, review successful experiences, summarize the lessons of failure in favor of consolidating and improving technology. Life centuries, happy geometry? I fly I'm happy, to enjoy the freedom of flight that is a non-verbal feelings of happiness!

Art-Tech Eagle Eye Brushless RC Helicopter

Art-Tech Eagle Eye 2.4Ghz 4 Channels Brushless RTFRC Helicopter(with camera)
This is the brand new 2.4Ghz 4 CH Eagle Eye Twin-Rotor-Coaxial helicopter. This helicopter isone of the largest dual-rotor in the market. The Eagle Eye is a beginner-friendly Art-Tech RC helicopter enjoyed by inexperienced/experienced flyers. Its unique design makes it easy toconfigure, control, and more fun to fly. It is designed to train pilots and entertain them bydelivering a stable flying platform capable of controlled indoor and outdoor flight course. The Eagle Eye has two sets of main rotors and a freewheeling tail rotor that does not affect flight. The counter-rotating main rotors eliminate the need for tail rotor compensation because they move inopposite directions,canceling each other rotational torque. In addition, the blade sets give it anadded bit of gyroscopic stability, which allows mere mortals to hover it with prowess.

The lower rotor provides cyclic control for the heli. To yaw the helicopter (left and right), one of the main rotors either slows down or speeds up to create an imbalance in torque. This results in theEagle Eye turning in the direction opposite to the rotation of the faster moving rotor. Since theEagle Eye is fixed pitch, collective control is governed exclively by throttle. On the Eagle Eye, theroll cyclic is a bit more responsive than its pitch cyclic (fore/aft control). This is because the verysmall range of cyclic control can more easily roll the heli than it can pitch it along the length of the body. This attribute actually helps make the Eagle Eye stable.
For a heli of this size, theresponsiveness on both axes is appropriate. For beginners, flying the Art-Tech Eagle Eye out of ground effect (first few inches off the ground)is not difficult either. Unlike other micros, the Eagle Eye tends to rise evenly rather than skateacross the floor laterally. If you punch the throttle, it has no hesitation in climb either.

Optional Li- poly battery will help to achieve better performance and longer flight time. 2.4Ghz 4 Channelremote control set includes complete Forward/Backward, Left/Right, Up/Down control(RUDDER, AILERON, ELEVATOR, AND THROTTLE). 2.4Ghz New Look Transmitter, NewLook Cabin, Improved Mixer/Gyro Control, More Stable Flight, even first timer can controleasily. Approximately 10 minutes flight time on each charge - Optional Li- poly battery will helpto achieve better performance and longer flight time.

Esky Coast Guard Marine Dauphin RC Helicopter

New 2.4G Spread Spectrum technology allows the transmitter and receiver to be 'locked-on' to thesame frequency ensuring much improved reliability and peace of mind when flying. Second, 2.4Gigahertz systems offers quicker, more responsive control, when compared to a standardfrequency system. Third, Operating at 2.4 Gigahertz also puts the radio control out of thefrequency range of any 'noise' caused by the other electronic components on your helicopter - suchas the motor, speed controller and any metal to metal noise - eliminating interference and glitchthat can affect traditional frequency system. Fourth, another main characteristic of 2.4 Gigahertzequipment from a Esky RC Helicopter club point of view is that no frequency control is needed.Eliminating the need to check everyone else's channel numbers, prior to flying. No more worriesabout turning up at a club with the wrong crystal in your Tx.

The US Coast Guard Marine Dauphin has been designed with an authentic scale appearance. It'sfinely crafted and highly detailed fuselage features a realistic ducted tail rotor and coloredindicator lights are installed on the top of the canopy, which flash continuously in flight. The tricycle undercarriage with retractable style wheel design will add to the enjoyment of flying thissuperb micro electric helicopter. Finally, 2.4 Gigahertz equipment use less current to operate thanstandard frequency systems. This results in longer flight time and longer life of your transmitter and receiver batteries! This helicopter is an ideal investment for those people looking to moveonto the larger scale helicopters, and can give you excellent training in preparation to fly the big birds!

The Dauphin was designed by TWF as a 4 channels radio controlled electric helicopter with co-axial, twin rotor blades system. It is easy to fly for the beginner, which possesses thecharacteristics of high sensitivity and full control of the real helicopter. The Esky Dauphin wasdesigned with separating canopy and fuselage connecting by a carbon fiber rod, which makes it practical and beautiful. The landing skid consists of three rolling wheels, which can slideautomatically while taking off and landing. The tail duct rotor blade can turn automatically duringflight, which brings you into a real flight state and brings more fun for your flight. Esky originalFlight SIM cable (EK2-0900A) is included in the packing, installing the FMS software on thedisc, and connecting the simulator port at the back of the transmitter to the computer's USB, youcan then enjoy almost real flight experience on your PC or laptop as well as to practice your flyingskills.

Walkera V120D03 RC Helicopter

Flybarless Palm Size Helicopter, Let's Go Outdoor!
This year every RC hobbyist are talking about Flybarless Helicopter. Now Walkera has developed the Smallest Flybarless CP Helicopter in theWorld - the Walkera V120D03. It is a Palm Size Helicopter, with Collective PitchFlybarless Rotor Head and a 10000KV brushless motor, it can resist light breeze in outdoor condition, so you can fly in beautifully in the backyardor in the park! It also has everything you find on a big helicopter, likethree CCPM servos, Brushless Motor and ESC, a 2.4Ghz All-in-OneReceiver, a Gyro (3-Axis) and a Motor Driven Tail Rotor, the only difference is the V120D03 is even better, because it has a 3-Axis Gyrowhich other RC Helicopters usually don't have.You may ask "WhyFlybarless is good?". Please allow me to explain.

Difference between V120D02, V120D03
Comes to the V120 Series, there are Two models with Collective PitchRotor Head, the V120D02 and V120D03. The only difference isV120D02 uses a rudder servo to adjust tail pitch to change heading,V120D03 uses a tail motor to change heading. Normally, rudder servogives a more precise control, but setting up is quite difficult for beginners.So factory made the Tail Motor version, this is much easier to setup for everyone and performance is also very well.What is 3-Axis Gyro?3-Axis Gyro means it can sense X, Y and Z axis moments, that means body leaning forward / backward, body rolling left / right, tail driftingCW / CWW, it will constantly monitoring any off-balance in alldirections, then it will give signals to all CCPM servos and Rudder servoto balance the helicopter, it works constantly and unless you have thehelicopter drifts to much, you will not even notice the system exists, please take a look at the following picture.
What is a Flybar?
The flybar is a short, thin metal rod placed on top of the helicopter. It is part of the rotor head’s structure, usually attached with a paddle on bothends. The flybar is a stabilizer. The heavier the paddle and longer theflybar, the more stable the heli. However, you can compensate by usingthe high-tech 3-Axis Gyro. The onboard Super Controller makes theV120D02 fly so well that it performs just like an ordinary rotor headhelicopter.

Why Make it “Flybarless?”
Flybarless means less moving parts. That saves energy and allows you tofly 20 to 30 percent longer. Also, less parts mean less repairing.Flybarless is the future of Walkera RC helicopters! The design of flybarless balance characterizes low power loss and great efficiency improvement.3 AXIS gyro, Aileronless balance control systemand amend the stable flight gesture automatically.Mature low voltagedriven systerm presents green, environmental friendly and safetyconcept.Low voltage and high torque brushless motor can provides strongand durable power.Mini size helicopters for indoor. It offers 8-9 minutesflight time after full charged.

Thr flying methods and precautions of Model aircraft

The self-important model aircraft fixed wing play to remember is that; The wind, the wind down. Take-off and landing are the two important links of each flight. So, we first need to grasp the principles and skills of takeoff and landing ship model glider before take-off should first observe the surrounding environment, affect the first condition of taking off is the wind direction, wind speed, the main thing is the wind to take off. Ship model glider can be cast off hand. Method is to push the throttle to the largest, with the aircraft level thrown forward. Can also be runway to take off. In general hand cast off the runway to take off more and faster to save power.

Matters needing attention
Throttle position: the greater the throttle, pull or push, the greater the propeller aircraft, faster running take-off distance is short. So, generally used maximum power take-off or maximum throttle state.
From the Angle of attack, Angle of attack is determined by the size of the lift from the ground the height of the front wheel or lift the tail. Large Angle of attack from the ground, the ground speed is small, smooth take-off run a short distance. But from the Angle of attack and not too much, from the Angle of attack is too large, will not only large in the resistance in a plane and make the aircraft growth is slow and prolong running distance, and will directly endanger the flight safety.
Flap location: let go of the flaps, can increase the lift coefficient, reduce the ground speed, thus can shorten the distance takeoff runway.
Take-off weight: take-off weight increase, not only make the aircraft off the ground speed increase, and will cause tire friction increases, the aircraft is not easy to accelerate. Therefore, take-off weight increases, take-off taxiing distance increase.

Airport elevation and temperature: airport elevation or temperatures can cause air density decreases, and put a face to pull or push decreases, and the plane speed slow; From the ground, on the other hand, speed increase, so take off running distance is growth.
Runway surface quality: the quality of different runway surface friction coefficient, sliding distance is different also. If the runway surface smooth and flat and solid, small friction coefficient, low friction, the plane faster, run take-off distance is short. Whereas the runway surface rough or soft, smooth take-off distance is long.
Wind speed: takeoff runway, in order to produce enough lift from the ground plane, regardless of wind or no wind, ground airspeed is certain. But running distance is only related with the ground speed, the wind run, small ground speed from the ground, so take off running distance is shorter than when there is no wind. The opposite is long.
Run slope: runway slope, can make the plane increase/decrease the acceleration forces.

This model is constructed and prepared with components thatwill handle sport to extreme 3D flight.

The flybarless system provides many advantages over a traditional flybar or balance bar system. A flybarless system has no cyclic slop. It providesinstant cyclic response from the servos due to less linkages and a directlink to the main blade grips from the swashplate. This results in improvedresponse time and enhanced flight characteristics. A traditional flybar actsas the mechanical gyro for the swashplates aileron and elevator movements and would resist motion as any gyroscope would. Dynam's 3axis flight control system utilizes its electronically controlled gyro systemto monitor elevator, aileron, and rudder movements. This makes thehelicopter much more stable. Another advantage to the flybarless systemis less components in the head assembly. This means reduced drageffectively enhancing the efficiency of the motor and esc along with flighttime, lighter weight, and reduced maintenance and repair costs in theevent of a crash.
All components of this E-Razor 450 are pre-installed and partially set-upat the factory to provide a ready to fly state out of the box with a Dynam2.4ghz radio system. The pilot only needs to make fine adjustments andtune it to their flying ability.

How to maintain remote control airplanes batteries

Battery is the power source remote control airplanes, generally in the case of a fully charged battery , remote control airplane flight time of no more than half an hour, It also has been plagued battery is an important problem. When we can not fundamentally solve this problem, We can only be made to better protect the flight time guaranteed, if you're ready to do not use the remote control plane for a long time, how should we to save battery?
Airplanes are lithium batteries if you want to save time, then be sure to bring the battery is charged only saved because the remote control airplane remote control helicopter or batteries are lithium batteries and lithium battery will gradually decay with the passage of time and lithium Once the low battery voltage is not stable it will damage the battery charge into a remote-controlled aircraft so if you want a more long battery must be fully charged before storing it will be more secure.

If the battery is not in use during the period of protection is not well, then when you come to play it again, you will find the battery time is getting shorter and durable, serious or even making the battery charge is not into power, so it a piece of waste batteries in when you do not play for a long time to get everyone's remote control aircraft for longer battery playing time, take out the battery is best kept separate, there is two or three months we will be the hub of electricity every time, but do not charge too long, but the best play is often remotely piloted aircraft put to use what is best.
Avoid full power storage. When not used for long, lithium batteries should be removed and placed in a cool dry place. Do not cut frozen, to avoid moisture erosion. Avoid using the car in high temperatures. If long-term storage, the battery charge to 40% after the placement, or the voltage stored between 3.75-3.85V.
To charge the battery, it is best to use a small electric current to charge, usually with 0.5C-2C charging current small little irritating to better preserve battery.

Avoid overcharge and over discharge, charging cut-off voltage is generally set for: 4.25V, discharge cut-off voltage: about 3.0V, discharge cut-off voltage, but also according to the actual situation, such as playing violent 3D, then the discharge cut-off voltage of the most good set at about 3.4V, below this value, it is easy to put off the moment caused a whole battery over-discharge.
These are the maintenance and use of the battery has been generally accepted methods, if you want to know more maintenance tips, then go to rctophobby.com.

The four common problems of remote control helicopter

With the development of the society, more and more people like helicopters and popular in all the big stores. At the same time, there are some problems about helicopters. The following I sort out four common questions of remote control helicopter, if you are a helicopter lover,you can look at it.

In the past, flying field, you want to see the helicopter flying,you may have to wait until the New Year holidays,quite rare. With the continuous development of the model of the market,you want to have a remote control helicopter,is not difficult it.However.Although the helicopter directly into the ranks of the few newcomers,but often these people in the face of the primary entry courses --- hovering helicopter,when this first hurdle of the examination,it has been more than half of the couple .

Concept and direction of the joystick has been,and why I still can not stop?After dumping,dumping around,up and down the throttle,rudder,these actions have been fixed stop, how to shake a helicopter or stop?Then the resulting frustration is simply completely engulfed the portals of its passion, how could such a merciless resentment apologized helicopter!Yan Chi Xia really looking forward to my hands red and black in a"fixed "word,it would be firmly fixed in the air.
I hover is how out of practice,which is already more than ten years ago,so nothing impression,but added that while teaching a friend when practicing hovering, ask the person to learn to fly not stop the feeling at the time.The results have so little common appreciate :it stuck in a bottleneck,once out of this bottleneck can have a significant progress.
Now we take a few memories of what happened in the situation hover.Are always felt quite naughty helicopter,front,back,left,right,always let us go.
Head of the right-wing,left aileron to fix the beginning of the moment,did not seem to react,so the next gut reaction would give more action in the amount. Finished!This is what it seems to become more and gave.Oops! Left to run. Before and after the action is also exactly the same,is it a "hyperactive child",did not stop for one second can do.Is not the body ministries did not adjust well?Or personal motor nerve underdeveloped?
According to my observation,often we fix the problem. Under normal circumstances,the body to the right-wing shift,we will repair it quickly to the left to straighten the body,when the tilt is the same before and after.The problem in this alone is not enough to straighten the body,because of inertia factors straighten the body,there is kinetic energy correction, correction to continue to move in the direction,the inclination of the body if the situation before and after the occurrence followed simultaneously,that may panic,even if there is three hands to help is not enough .

Therefore,the amendments must first make a little correction,until there is a body like a horde of completely stopping the phenomenon,this time it will be corrected immediately reverse the body's posture straightened,and subsequent corrective action . Various control surfaces inclined posture correction are using this mode of operation.This cycle, complete a variety of body tilt posture correction rudder movements,the more practice time to master the coordination and movement correction amount of time ,you are bound to have a completely different experience,such as the reborn camel leaps and bounds.
as long as you practice more.If you Want to be a helicopter,it had to lay a solid foundation,in fact it is not difficult to oh!if you want to know more infomation of Remote control helicopter hovering skills,i recommend to you rctophobby.com.

Great Planes Cherokee Sport-Scale ARF Airplane Overview

Hi, nice to meet you all here today. In such a nice day, I want to show you something about Cherokee. The name of the product is  Great Planes Cherokee Sport-Scale . Ok, let’s know something about it now.

Great Planes Cherokee Sport-Scale ARF is a 60 in model which could be rigged with either glow or electric power. This scale model is ideally suited to those interested in a scale-looking low wing model and is a great step-up after your first trainer. Being an ARF, they claim 4-6 hours of assembly and your off to the field. This model will perform the basic aerobatic maneuvers and should be an ideal first low wing airplane for the serious RCer.
Construction features and details on this model are no in short supply. Great Planes has a real winner on their hands with both a great looking scale plan in the Cherokee ARF as well as what should be a good performer when using electric or nitro propulsion. Great Planes explains all the great features on their website, but some of the highlights include: a bolt-on wing and tail for easy assembly and transport, tricycle landing gear, fiberglass wheel pants look great while providing low drag, and with a 5 channel radio you can even operate the included flaps. You will need at least a 4 channel radio (5 channel for the flaps), servos, and electric or nitro power to complete this RC model.

I first saw this plane at the Weak Signals Show in Toledo this year and I have to admit that it really caught my eye. I've always liked the lines of a Cherokee and think that it's a very good looking airplane, but something about the Great Planes model really made me want it. Please don't ask me to explain what it was about it because I'm not really sure myself. As an instructor I am regularly asked for advice on 2nd planes, so I really wanted to get my hands on the Cherokee so that I could know if it really was a good 2nd plane or not. So I shot an email off to the "RCU review meister" requesting this review. I was pretty excited when I found out that I was getting it, and felt a bit like a kid at Christmas time waiting for the "Big Brown Airplane Truck" to arrive.
