First of all, sorry for my bad english...

Any one knows witch of these options are the best for my quad?

40/50A Hk esc

Throttle setting options:

1 - Auto throttle range

2 - 1.1ms to 1.8ms (actual choice)

3 - Hard acc

4 - Soft acc

I'm having some random glitches with my actual config.
So I decided try tune the MIN_THROTTLE on code (to 1200), and did some adjusts on Tx ATV / end points to match the recomended Tx signal (1000 to 2000).
Now when i arm the quad the motors just start moving with the stick near of the center (+/- 1300). The stick on center i get +/- 1470.

Can you give me a little help here?

Thanks in advance,

I tried the option number 3 on the configuration of esc (Hard acc), did not notice any improvement in stability, however I noticed that all the quad vibrated in the air. I went to calibrate the esc's with option # 2, and now ... I'm waiting a little help or any tips.

P. S.: I did not see new glitches

50 Amps is quite much.
Get other ESCs.

I think these ESCs are not fast enough, the timing speed is too low for a multicopter.

They have to do a lot of controlling in very short time, I think 50A ESCs are made for boats or trucks unless you want to abduct sheeps and goats with your copter you should stick to lower amp ratios
