Offer me a good deal, I'm trying to put together my first gasser.

If you find one? These engines do not tune like any other gas engine on the market!! The low needle has to be set flush with the houseing and adjusted from there. The high needle will be in range at 2 - 2/12 turns from closed. Use the low needle valve to fine tune and not the high! Completely backwards from any engine I have ever had. Keep running it up till it peaks turning the low needle counter clockwise an 1/8th at a time till she reaches full RPM with no sputter. Then fine tune the high. Once you get it diled in they are great running and the most realistic sounding engines you will ever own. Mine was on a Great planes cloth covered .40 size cub and was an awsome combination. Also these engines have less power then thier .70 FS glow sister. IMO the best choice for a .40 size plane. Hope this helps out. Bobby.

Good luck If you do get one you will be like all the people I know. You will never sale it.

I want to put it on a hangar 9 Pawnee .40
