A friend of mine just flew his OMP 80" Edge for the first time Monday. Powered by a Mark/Moki 2.10 with Bisson sport muffler. He found it to be a tad tail heavy for his taste and has added about 3 ounces to the nose for his next flights. He has three metal geared servos in the tail, this is the kit not the ARF. What a great flying plane at about 12 pounds. The big Mokis never fail to surprise me, a brand new engine never run, he choked it about three or four flips with the throttle open, then closed the throttle and one back flip and it was running. Ran out about a half tank of fuel and then put it in the air with a heavy smoke trail, not a hint of strain or quiting.

My vote goes for the OMP Edge for your OS 2.1, The weight will not bother in the least.[8D][8D].....RJ
