Design the planes to be lighter.......It can be done without loosing strength in the frame.....result a better performing 3D plane......

That is what this is all about really....Trying to get the smaller planes to perform like the 33 and 40% planes....No they will never be exactly like the big ones, but getting closer.

Take a 120 size CAP or EDGE or EXTRA and put this 2 pound engine in it, or let's say it weights 2.5 pounds, you have lost nearly 1 full pound over the same plane with the current 50cc engine. My H9 1/4 CAP weighs 13.75 pounds with the BME 50, if I can get that down to 12.75 or an even 13lbs. it will fly a TON better.
