servo glitch

[Dickylew]

I have a Hobao Hyper st black which i have had loads of probs with since ive had it; now got another.

I notice i was loosing control over the throttle & brakes after checking noticed that the throttle servo was glitching/twitching and had very limited movement on braking.

I plugged in another servo and it does the same so its not the servo.

I plugged the throttle servo into channel 1 and was ok so it seems just to happen on channel 2.

The throttle on the transmitter has become very sensitive the slightest touch and the servo glitches.

Can anyone help with this dont know if its the receiver or transmitter its not that old only had since xmas.
