yeah a four stroke .70...............
think what i'll do is get mine in the air in the next month and fly it at half throttle and show them how my OS .91 FS surpass II w/pump is just enough power...........
i mean hey, i gave it to my buddy Marion as a gester for all his helping me when returning to the hobby, and i pretty much knew he would give it to his friend, but i just hate to see someone build such a beautiful bird and then stick the equivelant of a "house fly" for power on it.......not to mention all the lead it will probably take to get it to balance.
