Meh. We just measured the HP-24FES and it looks like we'll have about 8.5" of prop clearance in 2-point attitude. That's with the slightly taller undercarriage we built especially for this model. It's not a lot, but probably adequate when used judiciously.

A winch launch, or even an auto tow to 500', would address the prop clearance issue and also pump a bunch of kinetic and potential energy into the glider so you have that much left in the FES batteries.
