How to fly VTOL quad plane

#1

I test my vtol quad plane on a desk, propellers removed, I start at MC Altitude mode, the MC motors work as i expect, and then i switch to FW Altitude mode, but the push motor and Aileron keep still even I move the remote controller stick all around, only vtail elevator response to the RC.

I switch to FW stabilize mode, the push motor and aileron work, is this show that forward transiton can only be done at manual mode?

Who know how to fly this type of plane.

What version are you using? Just to make sure we’re talking about the same things.

Also, this might not work on the bench like you describe it because it probably needs airspeed. Am I correct @tumbili?

I have disable airspeed, and set params as described in this article

I download both v1.8.2 and v1.9.0-rc0, the phenomenon is same.
