Bipe Balance??
I got my first biplane this weekend, and flew it Sunday. I have never flown anything so hard. I set the cg about 20% of the bottom wing. It acts like the CG is off. oes anyone have advice on where a biplane CG is??

RE: Bipe Balance??
If that's a Waco, the upper wing is swept, correct?
The c.g. should be at 25-30% of the mac, wherever that falls on the plan view.
I suspect it's forward of where you have it.

I don't have the plans. It looks like it may be a bit tail heavy. The top wing is swept back. Looking at the drawing, my CG is way too far back. that would explain the way the plane acts.

Use caution when using this scheme. With a sweptback wing, MAC is not where it would appear to be from this. MAC for the top wing will have to be calculated, then the drawing applied.
