I found a deal for a pretty snazzy lookin' 980mm span Tiger Moth kit on Banggood, balsa and ply construction, that I'm thinking about picking up and building. Given it's made of balsa-and-ply and that I have a strict 'if it's big enough for ICE it gets ICE' policy regarding my aircraft models, I'm planning on going nitro with it.

I'm thinking of using a throttleable Cox 0.049 from coxengines.ca for it. Is that gonna be enough power? Or should I step up a bit and get an OS 15LA for it? I don't want so much power that I could 3D with it or set airspeed records, but I want enough power that 1/2 to 3/4 throttle is a lovely cruise speed while leaving enough in reserve for the occasional loop and/or aborting a dud landing. Also want to be able to take off from the ground on its own rather than relying on handlaunches.

The banggood page says that plane is meant to fly on a 2212-2216 motor. Himax says their 2212 is the equivalent for a .040 glow engine. So the Cox may work well. You might check into the weight of the bigger engines to see what kind of factor that will be.

It weighs around 20 to 25 oz so a Cox o49 will not fly it.
An OS 15 LA on a 8 x 3 should do the job.

Or if your runway sits at 5000' like mine you might want a touch more power.....

there is always the throttle
