Default Os91fs I

A lot of props used, only 3 rpm readings:
14x7 Graupner: 8400
12.5x7 Graupner 3 blade: 8800
16x10 APC: 5500 (just for fun, acceleration and idle are no problem)

My Ultra 1600/8 with 24 cell and 2.4:1 reduction turns the APC16x10 actually a little bit faster: 6000

Other used props, but never measured:
12x12 APC
14x8 Master
16x6 Graupner (wood)
