Motor Test letters for octo quad H

Mission Planner
1

Hello,

I have built an octo quad H and I was wondering if the letters in the Motor Test tab on MP are the same as in the octo quad X? It seems that octo quad H motor spin opposite of octo quad X but I can’t find any documentation to confirm the letters for octo quad H.

I would give it a go and try to hover it but it runs on 32" props and I don’t want to risk any damage.

The first motor to spin will be the one located directly forward in the case of + configuration, or the first motor to the right of straight forward in the case of X configuration. The motor test will then proceed in a clockwise rotation.

Seems they are in clockwise direction no matter what the frame is?
You can always try with no propellers and low throttle.
