RE: Evolution Trainer Power System
The engine is pretty good, but a bit heavier than the evo 46. The 3 blade prop is almost flat. I'm running a 11x6 2 blade on my evo trainer engine, and it moves along pretty good. Over all not a bad engine but I would get a 46.
evo 46 = Engine (Only) Weight: 13.76 oz
evo 45 trainer = Engine (Only) Weight: 16.32 oz
