@Yak54Fan: it was running _a_little_ rich, since the engine was not completely run in. Further more, I was running it on a 20% castor oil - 80% methanol fuel (no nitromethane or other additives. Hence the smoke :)
@fsj450: it had PLENTY of power; the engine was way too big for this bird (an OS 91FX would have been perfect) but that's what the folks at Graupner decided to bundle the plane with.

Good job he'd got the power on take off !! ..
Also looks tail heavy unless its how he's flying it ??

@fsj450 and no, the plane is not tail heavy, on the contrary - it was difficult to bring the CG to its position due to the weight of the engine.
