I was comparing flying power. In the air performance. The guy who built the often-crashed model gave it to me, so I would let him hover it when I swapped engines. Pull out power is a fair test. Overall, the Evo pulled the model around far with more power and authority in the air. I also had the engine on another model and it was obvious on the takeoff roll. I hardly ever tach the top end. Maybe on the bench when breaking in. Otherwise, it's all about top end in the air.

Yeah, that is pretty obvious, huh? Duh. Boca sponsored. Buy Boca for obvious reasons. I get it now.
