Yes, I have to agree. My Lehner is very smooth all the way through the powerband. 3S on pavement results in CRAZY wheelies at just about any speed. I'm honestly somewhat afraid of trying 4S lol...
BP - With your flightpowers I am sure you are getting better voltage under load than I am - my voltage is about 10.4v with the 3s under full accel load.
Any pics of how you are mounting the flightpowers? I didn't get them because of the way that the two wires come out of each side and couldn't figure out the best way to mount them without crushing the lower wire.
