Archie, you are right, it is the Neu F3A motor. Initally, Chip took a picture from the front of the plane and it was hard to tell. BTW, I've been running a couple fo the Neu F3A motors for the last 8 months and all I can say is_FANTASTIC! Not to speak of the outstanding/responsive service Steve Neu & Company have provided, what little I've needed them. I appreciate you providing the above info because I know Chip is busy trying to get the Visa in the air today. I'll contact Marcelo direct and order a couple of sets of the new improved/light wings for my 2 Genesis planes. Thanks__Everette
