Review by: AndrewWindy X Power
The motor is installed in a:
Windy Maxa at 2.23kg, 78.6 ounces all up,
Battery is a 4S, I'm running two types an 850mAh (Daves Toys Australia) and 900mAh black Hyperion.
11 x 7 Vladimers prop (A beautiful-looking propellor).
60 Amp speed controller. (set it to soft start)
Goes very well in both level and climbing flight, I am really impressed. It pulls about 53 amps in level flight based on battery recharge calculation ignoring losses and climbs at 10/14m/s.
Review by: ColinXPower F2925/8 Motor
A beautifully manufactured quality motor. I have only so far performed static testing on it but from these figures alone I think this will be a cracking F5J motor exhibiting excellent dash time and rate of climb in windy conditions where ballast will be used.
How its possible to design/manufacture such a small powerful in-runner motor is impressive. My static tests on 4S 850mah 80C battery with a 11x6 GM prop showed it giving 63A @985 Watts with min pack voltage of 13.4v. 60A is the recommended maximum continuous current draw for this motor but in actual flight this is likely to drop to around 50-55A with this battery/prop combination. Wont know for sure till I flight test it but experience tells me that in flight it should be under the 60A mark meaning that the recommended prop of11x6GM is probably about right. If you want a little more head room use a 10x6 or a10x5 GM Prop.
