Hi friends,

I have a RCM F-18 prop jet. This jet was designed by Mike Pastro in pusher configuration. Mine have a OS 91 vr-df with a 11x9 prop in nose, this thing is fast, but i have an obvious problem, the plane needs 30 oz on tail for balance! Is heavy and tricky on landings.

This jet is not suitable for ducted fan, so i thought to put the engine on tail like in original plans, but i have not a pusher propeller for this vrdf. Instead i have a Byron rotor.

Can i use this Byron rotor has a pusher propeller, or it will need a thrust tube and stator?

If need a thrust tube how much is the minimum tube large?

I have no experience in ducted fan, so i need your help.

Thanks in advance.

Javier
