Default O.S. 1.60FX Pusher

Bax, I am going to try the 1.60 in a pusher config. I will keep the tank close to the engine with the clunk facing back, and use large fuel line. I also have the stock muffler, will it give enough pressure without using a pump? What size 3 blade prop would work? I will have just over 9" clearance. Any other suggestions? Its the F-18 Hornet by Mike Pastro. Thanks

The stock muffler will give you plenty of pressure for the fuel tank. As far as a 3-blade prop goes, just take the 2-blade spec and either drop down one inch in diameter or one inch in pitch.

Now, the problem won't be to find a 3-blade prop, but a 3-blade PUSHER prop! Usually, a 3-blade prop won't work any better than a 2-blade prop, but it can help a bit with ground clearance.

howver the webra was with a pump so no issues with fuel

fule clunck facing the engine - hence - backwords!!!

i have got now a 15X8 pusher APC - i iwll cut it to a 13 size by length - this way i atill gain th epitch and rpm's and the prop wont scratch the ground.
