RE: Pheonix Extra 330S 60-90 Size
That looks like a good setup to me. I am not a 3d pilot but I think the DLE20 is the perfect gas engine for this plane. Mine is almost finished with the Magnum 108A and I had to move things around in the cockpit area of the plane. Because I counld not get the 120mm out from the firewall with the motor mount I used I made a battery area at the rear of the cockpit and moved my 2 A123 1100mah batteries there . I hope this helps out with the CG.
