Excellent Greg, have fun with it!

It's an interesting alternative which would be more in line with what you've already done. You could use hardwood dihedral braces to join the two wells together as shown. Of course, this could also be done with the servo's installed span wise as discussed. The rear bottom wing bolt plate on the Belaire even looks like the one on your Tipo!
