K - I'm surprised to hear of your concerns regarding the T-Rex. We did extensive flight testing/tuning of the flight model and our test pilots claimed that the performance was very real and accurate. It's a very responsive and maneuverable heli.

I do not see the same things you report. Tx settings often play a major role is how airplanes and helis "feel" when flying. Are you using the TacCon or are most your your comments and observations when using your DX7? Try flying using the TacCon. Do a full calibration and then see how it handles.

In the meantime, I'll investigate further to see if I can duplicate your situation.
