Ok, I give in. I'm going to build a 4*40 .......and put a DA 50 on the nose. Will it do circles then?
You prolly should start with the 4* 120 for a DA 50. Clip the wings, modify the control surfaces a bunch. Prolly could take a little weight out too, and figure a way to get the cg back some.
Or you could wait for that new hybrid design to come out and have a great plane from the start!

In all seriousness, the 4* series of planes are great for sport flying.
