While also scored with the regular classes, LOFT also scores the same flights in a separate “Woody” class based on Ray Hayes’s Wood Crafters rules:

– Wing and stab are built up wood construction.

– No restrictions on spar construction or materials.

– No molded D-tube leading edge construction.

– Fusalage can be wood, glassed wood or molded construction, including the fin.

– Carbon reinforcements can be used on any part of the structure.
