Default RE: F27 Stryker Part 9: Crazy DARK SIDE - Beginners to Dark Extremes

For those interested in 6S data on the Mega 16/40/2CE, I got some from the first three flights of my buddy's plane.

APC Sport 7x5
76.2A and 29,853 RPM.
Pitch speed of 141mph

APC Sport 7x6
89.3A and 28,679 RPM
Pitch speed 163mph.

APC Sport 7x7
100.5A and 27,442 RPM
Pitch speed 182mph.
Actual Airspeed 162mph

I took the readings at three seconds into the second pass of each flight, and the battery was 23-27% discharged for each of the data points.

The flights consisted of four full throttle passes of around six seconds. When it landed immediately after the last pass, the motor windings were 110F on the 7x7 prop. Outside air temp was 85F.

This motor can be a real speedster on 6S and 7" props with great throttle control. If the left stick is slammed up for most of the flight, stick with the lower pitch props. But for drag racing with cooling between passes, the 7x7 and even 7x8 should be good candidates for awesome speeds when the airframe is super sturdy and super slick.
