Hi all, I was pondering where to put this and think general chat is the best option.
Recently, I've been engaged in quite deep and meaningful stuff on this subject with Harford. It's resulted in me doing some testing with various, somewhat extreme settings by recommendations and chat I heard in the past. So here's a summary based upon function. All this was carried out using the stabilisation function in my Spirit Pro activated.
Throttle: D/R 100% Expo 0% - I see no benefit to making changes here for an electric motor.
Elevator: D/R 30% Expo 30% - This results in very gentle, more 'real' behaviour, which for a relative novice like me is much more controllable. The heli can still be flown forwards/backwards very fast but still within the capability of the pilot to make moves without panicking. This is reinforced by the stabilisation feature of the gyro.
Aileron: D/R 60% Expo 30% - This results in very stable flight and enough travel to give a realistic, gentle banking turn.
Pitch: D/R 100% Expo 30% - I was wondering why I might use any change here and tried some D/R but came to the conclusion that one can already create pitch curves to produce a suitable reaction from the heli. However, the Expo surprised me enormously. The main benefit was that the tendency for my dumb thumb/finger to give a very slight up and down movement on the stick as I use the rudder function has just disappeared. I will definitely do some more work on this newly discovered benefit. When I turn the heli on its 'Yaw' axis there is almost no change in the altitude and the pitch curve I use gives me very fine control to correct it.
Rudder: D/R 80% Expo 10% - This has resulted in very smooth reaction of the tail to stick inputs rather than the very snappy reaction I had from the previous setting of 70% D/R and 0% Expo.
To give a bit more background. My T-Rex 550 has a full pitch range of 24 degrees (-12 to + 12). The cyclic ring tuning in the Spirit Pro gives almost exactly 11 degrees each way in the Aileron axis. The tail has a tip to tip measurement of 5cm with left and right rudder inputs. The gyro is set to -70% ('Normal (Rate) Mode'). This keeps the stabilisation feature of the Spirit Pro active during flight.
I look forward to any discussions arising from the feedback.
