David, I hadbought an OSmax 46 vf-dfwhich is the predecessor of the newer 46 VX-DF and there's not enough crankshaft sticking out for a propellor on both. Strickly ducted fan use only. I was bummed. So I resold it on ebay. Would require some type of adapter to lengthen the crankshaft, if it could be done at all without vibration. IDon't think it's really possible to run standard propellors on it.

I have a NIP Hartori Magic 40 header and finally got an OS 40 VF. Now I just needbuilt up wood plansfor a 40 Magic.
