We have several T-hawks in our club, but they are all being flown on people's own radios, not the ones that Toytronics sells. No one has reported these problems.

BTW, if you buy the T-Hawk with the FM radio option (27 mhz) the throttle IS proportional. They added this feature last year.

Servo chatter and the like with the transmitter off is normal. As posted above. Receiver off first, then the transmitter on all set-ups.

I will be watching to see if you figure out what the cause is of the glitching.
