engine selection
 

I´m finishing a sig kavalier kit. which I modified to have a straight wing ( no dihedral). The engine I chose ( don´t have yet) for the plane is a TT .46 pro , although I own a super tigre .40 that runs great on my old trainer. Is there a noticeable difference of power between the two engines? Any sugestions, save the bucks, or buy new engine?

The TT will give more power. The ST will seem to be a lot more power with a "cleaner" (aerodynamically) plane though. I would suggest saving the funds for now and getting a larger engine for the third plane.

Agree with EXCAP232,use the money for more fuel.

There's another advantage that hasn't been mentioned. If you don't have much experience, you'll probably be pretty nervous your first few flights with the new plane. You know the engine you have now, and you're probably pretty comfortable with it. That's one less thing to worry about.

If you decide you'd like more power, you can always put a different engine on it later.

Thank´s all for the advice, I´ll go ahead and use my engine.
Happy landings
