I found the 791 to be a drop in replacement for the hs75 on my H9 P-40.

For clarity, the mounting holes and height, etc, all are just about the same is that what you are saying. On the new P-51, the servo has to mount on what is essentially a small plastic, pre-drilled, servo tray that is part of the retract mechanism. Thanks
