Ok.. I guess I'm not experienced enough.. The picture on the left is an image that was taken by a local newspaper of my BVM Maverick ducted fan. I flew it about 2 years and sold it. Maybe after another 39 years of flying I'll be experienced enough to read minds and understand that RTF really means "READY TO FAIL".

PS: Thanks for the link to the cheapo fan manual. I'll use their break-in procedure as soon as I fit the fan to the motor...
