RE: malfuction throttle servo
It sounds as though you are going at this alone with no mentor (instructor). I would highly reccommend getting some help or the airplane will probably not live very long even with the socalled stabilazation system.
Now for the specific problems, First do check that you have the throttle servo plugged into the #3 throttle port on the Rx. Just on a hunch I suspect there may be a communication problem here and I would have to ask this question: Do you realize that the full throttle position of the stick is up pointing toward the antenna and that idle position is downward toward the bottom of the Tx. Some people do get this confused.
Also have you tried reversing the #3 throttle servo? Just look in your manual for servo reversing.
