Mine started as an ARF but I recovered it and made a lot of changes for E-power, so its an ARFC. Been flying two years, several hundred flights. Excellent performe. Tom Morris-type control system, heavy duty hinges. I would strengthen the landing gear blocks before covering the wing, the short piece of hardwood that the end of the torque arm of the gear leg bears against came loose on one side. I can give the model high marks for accurate construction from the factory. I also strenghtened the wing panel joiners by inserting a CF tube in them, like the ham in a sandwich. I have some photos of the build if I can find the file.
