RE: KMP 87" Yak-54 What do you Think?

I remember mine being right on the tube and it was a tad nose heavy . No other trim was needed other than a couple of clicks up on elevator.

I am curious about your CG as well.

RE: KMP 87" Yak-54 What do you Think?

Thanks I have emailed a bunch of places now. I have a 25mm tube 920mm long. The 1" is too big.

That is about all I need to buy for this, other than different aileron hardware. :eek:
