More power fixes things too. Typical IMAC 35% airplane weighs 26-27 lbs and is powered with 100-120cc. Some would call this overpowered. The power helps drive strait lines. When I started flying pattern with electric setups I was used to the power to weight ratio of IMAC airplanes. As a result I found some areas of my setup were a little lax and had to pay more attention to details to get the airplane to feel locked in during uplines.
