WARNING to TradHeli users:
Do not attempt to fly AC3.3 until you hear otherwise from me. I have not even bench tested it yet, let alone test flown it. There are quite a lot of changes that have gone in that could be crash-o-matic for helicopters.
AC3.3 release for Tradheli is likely to be delayed.
This post will serve as the official release progress thread for TradHeli.
Warning: DO NOT FLY RC6! It has a critical bug that will likely end in a crash.
Warning for RC5:
RATE_YAW_FILT_HZ param will change defaults from 5Hz to 20Hz to be more suitable for helicopters. If you have never changed this parameter from 5 before, then it will automatically update the value to 20 without warning. This much faster filter will probably require reduction in your P and D terms, and the yaw may oscillate badly. Be prepared to retune these. As a safety measure, probably cut them in half for your first take-off.
Warning #2 for RC5:
I accidentally broke the Landing Detector. It will probably never trigger. You should land in Stabilize mode, or be prepared to shut down the motor as soon as it touches the ground in Alt_Hold, Loiter, Auto, etc.
