3 was good 4 seemed better !
after watching the simple quad video on flite test , i got inspired to make a mini quad copter . the original plan was to use the turnagy park 250 1680kv motors which were incorrectly rated . when i was shopping for the motors on hk i shopped for low amp and high thrust . so i bought them and also got the other parts like the plush, escs, the props and control board . the hk carbon fibre sheets are awesome and they are super smooth and super strong .I designed a mini quad along the lines of davids(rcexplore) quadrone . i have access to a cnc mill at work so on lunch i quickly cut out the frame.
