Having issues with consistently getting Aero/Pxhk to spin the motor up to full speed when set to Auto and a mission loaded. I have basically set TKOFF_THR_MINACC and TKOFF_THR_MINSPD to 0(zero). Sometimes the motor will spin up with a quick forward throw, and then go to manual to shut it down, switch to Auto and go again with a quick forward throw and the motor does not spin up.

The reason for setting above value to 0 was to eliminate any minimal checks. Previous values were set to 3 and 1 respectively and NO and same results, intermittent motor spin up.

WTF am I missing here or have set up incorrectly?

It should spin up without a throw with those values. I think your problem is elsewhere.


These are my settings. It will start instantly, but the TKOFF_THR_SLEW value will make it do so fairly gently,. giving me a chance to get set.
Delay value is irrelevant as the MINSPEED and MINACC = 0.

I have :



ARMING_REQUIRE: 64 (RC failsafe only...really should set it to 72 for field work)


What if you reduce the values so that you can arm it by doing fake throws? Take the prop off first, obviously :).
Might be one way of testing it, without bungeeing it into the ground everytime.
