Naza and Ultraesc

[supermagico]

Good morning,
this is my first post on this forum.
I have a small homebuilt quadcopter with a Naza FC V1, with 4 MT-2212 Tiger Motor
Yesterday I replaced my 4 esc Turnigy plush 20A with 4 Ultraesc 20A from flyduino.
I can configure ultraesc but the engines do not want to start.
Do you have any suggestions for me?
Thank you very much.

Sounds like a throttle calibration issue on your ESC's.
Sometimes they have to be programmed to see 0% to 100% throttle.
Manual for your ESC's should show you how.

As well, it could be the NAZA is not seeing the correct endpoint for throttle therefore it
disarms your motors.

Many thanks for the answer, I tried to invert the 3-pin connector of the Esc on the MC and magically the motors started.
The manual of Naza shows that the first pin from the top is the signal, but in this mode the motors do not want to start. I will check the welds on the UltraEsc.


P.S.:
Can you give me an opinion on these settings?
Pitch 160%
Roll 160%
Yaw 160%
Vertical 170%
Attitude 120% both

The quad has a distance motor to motor of 56 cm, the full weight is 1450g.
The motors are Tiger Motors T2212 (750kv) with Graupner E-Prop 11x5.

Sorry for the late reply Supermagico !

I had a little issue with the UltraESC waited for a replacement. Now all good will try to get them tested this week ! There is no throttle calibration for the Ultra ESCs you can set the range in the assistant tool for them.
I think if i remember correclty from the assitant the the lowest PWM signal setting it 950, but i talked to felix the man behing them a week ago or so and he said that they arm at PWM inpulse of 900, which the naza gives out !
I know that from dealing with the ESC32 and the naza and they didnt arm before the setting was altered to 900. If there isnt any hardware wiring issue i could still be the start PWM signal and than we should tell Felix !
