Hey guys,
Wondering if i can get some help. I just scratch build a rotor-bones x quad and am having a terrible time getting the thing PI-edited correct. I set it according to the tuning guide:
Roll/Pitch P-gain: 30 (For a small 25cm size set to 20)
Roll/Pitch P-limit: 100
Roll/Pitch I-gain: 0
Roll/Pitch I-limit: 20
Yaw P-gain: 50
Yaw P-limit: 20
Yaw I-gain: 0
Yaw I-limit: 10
I can't get above 34ish on the roll p-gain before it oscillates terribly. Once set to 35 to elimination the oscillation, the overall control is also terrible. I increased the yaw p-gain to stabilze the tendency to yaw left. (y-pg 75/y-ig 75)
Here is my setup and a pic attached of new rotor-bones X vs H-Quad.
Is the props the problem? I thought i understood a larger prop would still work but may not be best performance.
I have upgraded the booms so that motor-to-motor they are about 25" apart. Reason for this is because i was previously flying an h-quad same dimensions and it flew great but heavy. So i was trying to match the dimensions but lighter center frame to increase overall performance/flite time.

- kk2.0 v1.6
- Turnigy D2836/11 750kv motors (attempt to replace the dt750 i had b/c stock was a problem and needed a new motor)
- 11x4.7 props (leftover from DT750) recommended is 9x6
- plush 30A ESC
- 2200 3S
