Create PX4 Frame with Booster Motor Mode

Hello guys,

I’m building a quadcopter using a booster motor (see : Booster Motor — Copter documentation)
My config : 4 auxiliary motors in X config to manage pitch-roll-yaw + 1 main motor assuming 70% of the thrust

So first, i’ve been using an Holybro PX4-mini uploaded with “Arducopter V4.2 ph4-mini” but for many reasons I would like to try upload PX4.

In the frame type I can’t see a frame using this config/function, do you know if this function has been adapted since arducopter?

I can try to create a new frame category, but is the booster function implemented in px4?

Thanks for you help
