Just got a PT-40 Trainer for my son and it was all ready to go.

Did the ground check and as soon as you get about 25 feet away the servoes start to twitch. Gets worse at a farther distance.

Batteries are fine, Disconnected each servo one at a time, bypassed the switch, took the reciever and antenae out of the fuse with all still hooked up and no change. If I grab the antennae with my hand it stops immediately. Also stops as soon as you pull out the antennae on the transmitter.

Any additional thoughts or do I have a bad reciever/transmitter.

Thanks,

Del
