The new feature that was added to APM. When you arm your uav, motors start spinning slowly. I think that’s a brilliant idea. It removes the trouble of having to go near the UAV to check wether it’s armed or not.
Here is the deal, in one of my quads, i have stock Skywalker 20A ESCs and when i arm the quad, they start spinning.
On the other quad, i have Turnigy Plush 18A ESCs flashed with BlHeli fimware. And they don’t start spinning when I arm my quad.
I’ve done ESC calibration on both of them.
Theyare both APM 2.5 boards with exact same version of APM loaded.
I tried to change min_throttle(?) in full parameter list on the second quad, it didn’t help.
Also changed “spinning speed when armed” from all the way to very slow to fast. Didn’t help either.
What could cause this?
