Bring Back the Llama Co-Axial Bicopter

[BrockTechnologies]

Describe problem solved by the proposed feature

1.8.2 ( I have not had the chance to look further forward) had the Llama co-axial bicopter. I thought that the previous release had mentioned that it would be brought back into the next build. The new 1.15 does not. Can you please add that airframe type back into the new builds? I am trying to work with bi-copters and cannot find the code. I am currently using the mRo.

Describe your preferred solution

Bring back the Llama or co-axial bicopters and more selection of helicotpers to the airframe types. I have a bicopter which I cannot find out how to get to work with the newest build. the bicopter does not have an RPM gov. it uses RPM to change thrust. top motor is just rpm bottom is pitch roll and rpm. again neither have gov and differential rpm is used for yaw

Describe possible alternatives

unknown

Additional context

llama from 1.8.2 worked just fine
