trex450 se v2 jr77 3d gyro dx6i radio

when doing piros, i get crazy bounce back ,, like half a turn , gyro gain set at 54, any higher and I get tail twitch,, rudder travel adjust at 100R, 110L , gyro trav. adjust 100%
any thoughts?? thanks

after trying everything I could. I sent my gyro back to Horrizon. Waiting to hear what they say. Has anybody else had issues with jr 7703d gyro's I have been looking at the new jr g270 gyro, any thoughts?

update,horizon sent me a new gyro, said they could not find a problem with the old one, but out of courtesy sent me a new one. reinstalled new gyro still had problem, so decided to try another reciever. be damm if that didn't fix it. no more bounce back, tail holds great, had a days worth of flying in it today. never would have guessed.
