I have never tried it above grace, as I usually try it in street or home floor, but I dont expect from a sonar to behave well on grass anyway.

P, I should always be positive.
D is either zero or -1,-2,-3

BTW u can fly in P only and I, D are zeros
then increase step by step

X configuration confution

Hi

I fly X and ive had a ahell of a time trying to get the hefnycopter to work because the setup is incorrect.

This is from your code:

Quad-X

M1 CW M3 CCW
\ /
\ /
\ --- /
| |
/ --- \
/ \
/ \
M2 CCW M4 CW

This is from your web user guide
M1 CW M2 CCW
\ /
\ /
\ --- /
| |
/ --- \
/ \
/ \
M3 CCW M3 CW

The question is which should we trust???

The current one is only compatible with kk2.0

regarding KK2.1 maybe HefnyCopter supports it but not soon.

Dears,

Hello All... yes I was away for a while ... sorry for that...
today I was testing ALTHLD and updated my values to:

P 40 / 65
I 5 / 50
D 0 / 0

I noticed that if P limit is high the quad will oscillate the same if P value is High ,...
this sound logic as we need sudden fixes with low limits....i.e. ALTHLD saturate with P often.

..................................
Gyro was
P: 45 / 200
I: 10/150
D: +7 / 75

Gyro YAW:
P: 50 / 80
I: 50 / 90
D: 0 / 0

Acc.....................
P: 50 / 200
I: 15/170
D: -3 / 30


Best Regards

Quadcopter Sessions

Dears,

I have uploaded some videos of sessions I made to discuss some concepts that I am sure most of us know -even better than me- but I hope some can find these session useful for them.
