It seems to work great, I'm just wondering, why this isn't also an acceptable solution to running a 4 blade prop instead of all the CG issues that come with a heavier motor?
I understand it's the same as limiting my throttle to 3/4 travel, but I get plenty of speed with this setup without burning anything up while keeping the scale look of the 4 blade prop.
You are pushing the limits. It might work for ever or it might blow up tomorrow. Throttle limiting is not an effective way of reducing the power the ESC sees. An esc is a switch. It varies power by turning off and on at different speeds. When it is on it is full on. Meaning that it is seeing the full power the setup is capable of producing.
Also, Eflite motors are usually overrated so you probably
will be safe. Just know you are riding the top edge of the limits of the components.
