Thanks guys!!!! My only concen is verticle climb ability and hovering. Will the OS 70 or the OS 55 have enough power for this?? They are both great engines. I have them in 2 of my other planes. What size prop would you recomend? I did not know about OS's new 81 engine. I will have to look for it. And yes, I ordered the yellow and orange version.
Just looked at the Tower Hobbies Web site. They discontinued the OS 70 Surpass! I CAN'T IMAGINE WHY.
One more thought, is there enough room in the cowling for the Saito 82 without a lot of cutting??
