Hi CGr,

first of all, I just want to thank you for replying,

Yes, I do have control over the control surfaces and throttle. I have no problem with it. The problem occures when I leave the plane sitting on the ground  for few seconds without giving any input. All of the sudden all the servos start moving and the motor start running for 2 or 3 or 4 seconds. It seems like I lose signal. But I am not sure what I should check. The ailerons were added. They work fine. Right input move the right aileron up. Left input move the left aileron up. As for the transmitter combination, I am not sure how to check that. I bought the RTF version of the Mini Mag from bphobbies. It comes with its own transmitter Hitec Zebra 4 Channel Transmitter and the receiver  Hitec HFS-06MT Receiver.
