I put a new motor on my Mig and slaped a 5 blade Vario prop on it. WOW what a differance it made in flight. AUW is 6.6 lbls with spring air retracts and a 5000 5S batt. Getting 1200 watts at about 65 amps. Just about 1 to 1 thrust, maybe a just a hair under up here in the high country. I live at 6000' elevation so getting big power is kinda tough. But every time I go the 200 miles to Vegas and come down about 4000' of elevation it realy comes alive!!!
