A 170 is not actually a lot of power for this airframe, it flies scale but only puts out the equivalent power of a 120 single.

It is definately the ideal engine for this bird, if only for the sound, oh, and one flick start.

It does however require a keleo exhaust and a decent on board glow system, it's a waste of time without those two items.

Capt Ron, try some right thrust on your engine.
