AutoPilot on a Rocket

i couldn’t find a topic on this so i created a new one hope it’s ok (I’m a bit new to forums…)

anyways here’s the reason why I’m reaching out:
I’m working on a plane which will be launched almost vertical using small rocket engines. To stabilize the launch i chose to use an APM i had originally bought for quad project.

But i can’t find anything in the setting to get some kind of cruise mode but with a 80° pitch angle. I’m thinking of creating a new flight mode to program what i want but before engaging in painful programing (an area in which I’m not that good…) does anyone know of any option in Mission Planner that could help me ??


A 2 second google and I found this:

Thanks, Grant.
