Good, neutral point for balancing a Yak54
 

I have an FMS 1300mm yak54 that i've been tweaking for a while now, and I have balanced it as per the manual. But it turns out that at that spot, it becomes violently tail heavy. As if someone is drunk at the controls.

So I'm looking for a good point to balance it. I've read at a few places that a good starting point is the centre of lift on the wing. Are yaks at their best at that point or a little aft?

3DFoamy doesnt sell a Yak54, (this is the www.3dfdoamy.com) support forum, and I see my mod tools are gone so I cant move this to the appropriate forum.

oops, my bad. When I saw "3d foamies", I figured it was just that. support for all 3d foamies. Mods, feel free to remove this post, if you so please. :)
