Hi all Needing to know what size of glow engine do i need to replace this electric motor Atlas 2312/09 Brushless 3S 1200 MAH Lipo. here is a photo of the plane im building.

Thanks

Hi heres my progress Used TT .07 engine so far only 8ozs

I don't know anything about the electric motors. I just go by the wingspan, wingarea and overall weight. Together with the aimed style of flying that's all you need to chose a glow engine. On glow they usually come out a little lighter too.

What is the size of that plane?

Mr Cox this plane has a 36" w/s, 25.75 long, wing area 303 sq in. and weight is 17.3 oz right now im at 8 ozs.

Thanks for the help..

A Norvel .074 or a .10 engine would fly that fine. The TT07 should work too, it is a little lower than a Norvel .061 in terms of power and it is heavier.
