Feyd,
The A-10 looks good visually, but the engine selection is actually limited to only one -- the D21-7T. Double-click each of the simulation runs and take a look at the "Launch Guide Length" data. The "B" and "C" engines both require 10' of guide length or more before they reach safe flight speed. In other words, neither are satisfactory to get the model off the pad and fly correctly once lit. This design has a lot of drag with those big wings, and needs plenty of "oomph" to get moving. Now, if only we had a core-burning engine, like the C5, it might be different.
Jon, you missed the "Velocity at Deployment" numbers on those "B" and "C" engines -- both deployed at over 55 FPS, meaning the parachute would likely explode and fail completely the moment it came out.
Having said this...
I wonder if this could be convoluted into a BG?
