Here's my Kadet Senior that will aslo have 19 LED's, no dihedral, barn door aileron's, bolt on wing's yadda yadda yadda........

This is my first attempt at the removable bombay. I want to just put on a hatch for when it's not in use. I think I need thicker ply for the doors but so far the biggest problem is the offset of the servo. It's centered when closed but the doors won't open evenly. Perhaps a linear servo dead center is the answer, you can converst a standard servo pretty cheap. If I mounted the servo at the bottom near the doors I could use a round servo arm and set it up like retracts which is another possibility.
