Sounds like Stick PID like MK does - faster yank on stick results in more aggressive movement. Sorta like expo I guess. Read about it on MK wiki.

Any ideas? Video links?

Thanks
so the red led is only on now i presume.
did you had to reverse channels like rudder?
try below that sequence

when i arm the board i need to do this:
- power on
- full throttle, right ( or left) rudder ( led flash one time) ,
- throttle minimum , right ( or left) rudder ( led flash one time and stays off ) board is armed now , only red led is on.

When with throttle low i put rudder left (or right) ,led flashes one time and board will disarm , and again with throttle low i put rudder right (or left) led flashes one time it will arm board again.

FYI if throttle level is lower then 20% and you give rudder left( or right), board will disarm !!

PID 1.22c is also in english!

I've changed for the better understanding something, see attached file

snapper , you can use PID 1.24 also for firmware 1.22 version right?

I downloaded 'mscomm32.ocx' from somewhere and placed it in the directory with the PID software. But I must say, I have still the problemless XP

Thanks,got it ....after playing around with this sequence I managed to get the board to arm now for a test flight.

Test flight with 1.24


Hovering looks OK, but still having a drift issue by cold weather

I calibrated all 4 ESC, but still have bad throttle response, almost full throttle then it will just lift, then this setup will be useless to fly
I read that Mike Barton and HappySundays had the same problem and HS stated :
FF board reduced my throttle range to 55% of my actual TX's output.

i use C2830 880Kv motors and 8x4.5 props and had no throttle problem with KK board.

does firmware 1.24 improve throttle response ?,
and did Mike or HappySundays solved bad throttle response?

I have no throttle problem with v1.24.

FF outputs 1ms (not armed), 1.2ms (armed with minimun throttle) and 1.8ms (armed with maximum throttle).

Maybe you need to calibrate "RC cal" with PC

Well strange as it was, it actually works out well for me as the compressed throttle response goes from just under takeoff speed to full speed, unlike Jaccies, who has the opposite problem.

The problem is that the FF firmware does not offer an ESC calibration mode. You could, I guess, use the GUI and the throttle override to calibrate your ESCs but you'd have to power the board separately of course. So, disconnect ESC power input, power up FF board, run GUI, go into motor screen, set max throttle, power on ESCs, wait for beeps, set min throttle, wait for beep, power off everything and reconnect everything. That might work...

Rol*Pit_D: Adjust after the "P & I" to decrease repeat bounce or oscillations after a test strike/upset.

Thanks Manu. Also I just used experience from tuning other flight controller PID's and applied it to the FF. Yes there is PID Info section in the
Quadrocopter and Tricopter Mega Link Index and I added the DIYDtrones link Thanks for that too
Cheers,
Jim
