RE: Need some thoughts on my Seagull Ultimate Build.......>>>
Way to much engine. IMHO The SG Ults are on the heavy side to start with. A DLE 20 would be a much better choice. I have owned one SG and 3 GB Ults in this same size. The one I have now is OS 1.20 two stroke powered. It has way to much power and the DLE 20 has a little more than it. If you do stay with your engine choice, be prepared to put the elev and rudder servos in the tail. With the 1.20 I have two mini seorvos in the tail and the CG is right on.
