3W 75, 85 B2, or BME 102/105 for the H9 Sukhoi??
3Dn. . the BME 110 will be out in a few weeks. . forget the competition. . they are 2 lbs heavier and make no more power, and a ZDZ80 can't even think of getting close.
If you get a 105 right now, btw, you will be able to upgrade to a 110 by merely changing out the cylinders and pistons, and getting new mufflers. Kind of makes it a simple choice, doesn't it?
