We are working on the new balsa F5K glider kit.
It features a polyhedral wing, with ailerons and flaps but will have an option to build a dihedral wing instead and have 2 servos for the wing instead of 4.
The projected AUW is 320g, and considering the increased wing area, it will meet the F5K min wing loading requirement.
