ok... finaly got the prop on... rigged up a system where the prop was inside a short tube... ran the motor on full throttle with 1/2 charged battery.... this tube had a curve in it.. same tube from the stock intake that connects to the MAF of our svx, i just cut off the flex piece... but anyways... id have to say it pushed out if not more or equal to my gas powerd leaf blower with a 200mph wind rating on it..... i had to have my rigged system completly taped down lol...i will take photos soon, and a video on youtube...
