CG for SE5a

Hello, I am finishing an electric SE5a, 40" WS about 3.5 lbs and I need to find the best CG, this will just be a WW1 floater, no 3D, anyone with this data would be greatly appreciated...Thanks

Here are Pics of a Dave Platt SE5a precision scale design. Appears to confirm CG location with the previous post. Looks good! Nice work!

RE: CG for SE5a

The old rule of thumb for straight winged biplanes is to measure the distance from LE to LE and at the 50% point measure back 30% to establish the CG. Might worth a double check on your SE5A. Nice plane!
