Hi, I’m new on this forum (RC Jet), habitually I go to Extreme Speed Prop Planes sub-forum but I need more speed now! I don’t find a lot of info on ducted fan for nitro engine. I want to build a jet with an OS.91 DF engine... At the moment the only one I could buy is the Dynamax, any other suggestion? Or somebody have something used for sale?

yellow aircrasft and BVM will have alot of what your looking for in thatsize range. There is a ducted fan thread here in the jet s section where you can get a lot of your questions answered

I have a BVM .91 in excellent shape that is ready to drop in an airframe. Newly rebuilt, has not been run since the re-build. Send me a PM if you are interested or see the thread on glow D/F engine selection. I'm not big on cross-posting, so I'd welcome PM's if you have any questions.
