"And what about the "FOV" ... , could be better no?"

"I am building one(s) currently (a experimental quad & hexa)..., with tubes/sandwich fiber/foam/balsa and a minimum number of 3d printed pieces , all in the optic to be modular and easily modifyable.
Now, I still don't know where to start on how to…"

"Can you make a sketch/drawing of your thoughts?Thanks"

"Ok!..., I think that a proper gyro ( velocity) PID can handle asymmetry better than the "final toutch" mixing couplings..., my video proofs it.
Mechanical symmetry is number 1, PID will do the rest..."

"Could you explain what "coupling between axis" means , a vidéo or drawing to illustrate it ...

Thanks,
Manu"

"I know, APM does wonderful things, all i want to say that "simple" is not a word for APM/Pixhawk ?..., 
Simple ACRO:
Basic gyro-only-error-PID loop, and a big error accumulator will do wonders.
If someone can tell me how to get "heading-hold" done…"

"Hi, late reply...
I am still surprised on how difficult it is in APM to tune the Rate-PID's. I am used to do it with KK, Mwii, CleanFlight, and my own gyro-only KK-based PID code.
I am missing the HeadinHold feature (ie the I accumulator) Any…"

"Another thought on symmetrical tube frames and the amount of tubes needed:
Square: 4
H or I : 3
X or + : 2*sqrt(1^2+1^2)=2*1.43=2.86 almost 3...

I like H frames because I need only 2 fixtures
And it allow placing equipment all along the frame,…"

"Do you agree there is NO difference at all between a square H / I and an X / +, regarding flight characteristics as long as the center of mass is located at the same place?..."

"Hello,
Is this possible now in their latests releases?
Thanks,

"I never saw a transmitter that is so complicated to set pwm 6 positions with 2 switches, horrible!
I also, get only 5 distinct positions, grrrrrrrrrrrrr"
