I have installed an Igyro srs +gps on a pitts S12 python 2,80m with gp176, old powerbox evolution and 2 futaba sbus receivers.
This models flys well without gyro but needs many mixing to improve flight behaviour:
- Rudder to aileron 20%
- Rudder to elevator 25%
- Throttle to aileron 4%
- Crows to elevator 5% when using ailerons as crows.
It's a smooth but 3d-happy model with 30° to 45° deflections for all orders.
I use only the low wing ailerons on the gyro, as I need 4 different commands for ailerons used as crows.
I installed the igyro to avoid any mixing.
So I removed all mixing (except the crows but without elevators), I used the flight assistant and everything was correct, except that I reached 100% on all axis in normal, and 60% in heading mode without oscillation either at slow speed or at high speed.
Hovering and harriers are now quite easy and the crows are well corrected by the gyro but I still need to correct knife edge in elevators and ailerons either in normal or in normal mode.
I tried 70% for heading in elevator but I felt some strange behaviour at slow speed, eventhough I didn't have any oscillation.
I had to put again my mixing and it was ok.
The gps indicates a max speed at 174km/h and it sounds good to me.
My questions are:
- Should I try the "gain×4" to look for oscillations? so as to improve the knife edge behaviour, even if it is not a sluggish model
- Is it a problem if I use mixing with the Igyro?
