Hi all I saw this on Facebook from Bobj from skyline models
For those customers who seem to have having a few issues with their 130X’s, below are tips how to make sure your 130 stays in the air
Roll on take-off
Fly bar less systems do not like it when the helicopter is light on the skids. As soon as the blades start spinning the pilot needs to start flying it. When taking off the 130 X, increase the throttle, once the blades are spinning rapidly increase the throttle to pop it off the ground. Letting the helicopter spool up slowly can cause vibration which will cause an unwanted roll. It is also recommended to take the helicopter off of a smooth surface such as concrete. The helicopter being so light can get stuck in the grass very easily.
Tail Resonance
Upon spool up, the helicopters will experience a vibration in the tail assembly, but only during spool up. The tail is hitting a resonant frequency at a certain head speed; this is not a problem, it’s just something the 130 X does. The key is to quickly move through this head speed range. To avoid this issue, advance the throttle from low throttle to about 75% throttle immediately. The goal is to pop the helicopter off the ground as quickly as possible without letting it stay at the head speed that causes the resonant vibration. Once it moves past this head speed and is off the ground and in the air, the vibration will disappear.
Tail resonance can also occur when holding the helicopter and spooling it up. Helicopters are not designed to be held static when the rotors are turning, and Horizon does not support or recommend doing this!
Gear Stripping
One thing to check is to hold the head and try to spin the tail assembly, using light pressure. The tail shouldn't spin. If the tail spins easily check the gears and make sure none of them are slipping on the shaft. Again taking off of concrete or something smooth is better. Since the helicopter sits low, grass can grab the tail and potentially strip a gear. If the tail is not holding, stripped or slipping gears is generally the cause.
Motor Temperatures
The motor temp is warm but well within an acceptable range for a brushless motor. The motor temperature is approximately 160 degrees Fahrenheit depending on ambient temp. A high performance motor does generate heat. As with ALL electric motors, it is advised to allow the motor to cool between flights.
Servo Response
When the motor is off the gyros are off. The servos will work like you are expecting them to: hold left servo goes left, centre the stick the servo centres.
When the motor is on the gyros are on. Therefore the servos act differently. When you hold full left rudder the error builds up. When you centre the stick the gyro still thinks there is error and therefore continues to hold left rudder in. If you were to hold right rudder in for a little while, don't jab it, hold it in for a couple seconds it would then go right. Once the motor is turned off the servos will continue to operate this way for 4 seconds
