Wow Delta,

I didn't think the .40 would be so under powered. I believe the LA series engines give more punch then other regular .40's. If I remember, O.S. labled the LA as sport engines. The .40 LA probably matches the power of a regular .50 2 stroke, I could be wrong. When I was taxing, I hit the throttle to full for a second or 2 and the PC-9 really moved fast on the ground. I agree with ya, no matter what .40 I use it will be under powered. I'm just trying to get this thing in the air, I been having it for a year. Maybe I should buy another kit for this .40 and put the PC-9 on hold till I get a bigger engine.

With a Saito .72 I bet your PC-9 really goes vertical!!


Thanks again.
