RE: cheap ducted fan for 540 size brushless
Hi, what size fan are you looking for..Midi fans I think are 90 mm and probably can take that 540 motor you are talking about. I've got a 3-3.5 inch glo engine powered fan from a Kyosho F-86
runs great. There are few cheap ducted fans...WeMoTec and Kyosho and Kress are your choices...GWS are cheap but small to me....anything else is big bucks...
