Gonna put a fan unit in an Electra, I've never flown the 12s just the 10s. But I wanted to hear from people to help me decide which one to put in. Is the extra #'s in thrust worth the extra money, weight in lipo's etc..Or is the economical 10s the better route?? I know at the field, with the setup I have, the 10s is easier for me as I can charge them together. would like to hear from people who have flown both..Any input would be appreciated..Thanks
