What tail blades? I have had great results with the 37mm blades, both with GY520/9257 and GP750/410 combos.

Most likely its your ESC on the way out. Try to reprogram it without the governer run 100% throttle curve just to see if the tail calms down by adjusting the gain. Also check your Gyro settings. You should use F3C mode for a smaller Heli and check your servo selection Blue for 1520us servo Red for 760us servo and violet for anolog servo.I dont have this Gyro in my 250 but using it in my 500 and F3C mode seems to be the best.

Hey.

You haven't mentioned it but if you are running govenor mode on the ESC then this might be the source of your tail kick. Others have mentioned that using govenor mode gives them a strange tail kick from memory.

Your much better off just running Throttle curves, just stay above 80/85% of power for all flying.

Hey.

Ah sounds like the ESC was just on it's last legs and it's demise is probably the proof.

With your next one then you shouldn't have any problems and can enjoy the model.
