XPower F2925/8 Windy 102g 1380 RPM/V

Bought the Xpower 2928/8 1380Kv from hyperflight, because I wanted something that wouldn't be a squeeze to get it into a 40mm nose.
I was a little nervous about it being sufficiently powerful, bring only 28mm diameter, but I needn't have worried.
Takes my Arthobby Avatar up at 8.6 m/s on merely a 9.5" x 6 " prop, drawing 33 amps on a 1350 50C 3s battery. Weight 1620 grams. I was impressed. Would no longer consider an inrunner with this beauty available.
One complaint, it didn't come with any mounting bolts, had to buy them separately!

This motor replaces a much heavier motor/gearbox combo in my 3800 Xplorer using 11*6 prop and 4S 850mah power pack. I'm entirely satisfied with the performance. Thanks to HyperFlight for a very quick delivery.

I am using this in a 1550g f5j model with 11*6 GM prop on a 3s 850mah pack.
30 second climb gives 300m.
Puling 40amps.

Lovely and smooth reliable motor.

I purchased this motor for my Ava 3.2m electric. It replaced an older and much, much heavier Hacker B50 motor (!!).

So far I'm extremely pleased with the performance. Excellent power on a 12x8 prop and 3s 1350 mah battery pack. Very quiet as well. Running it through a 45 amp Castle BEC. Plane weighs 50 oz all up and I think this is basically the ideal powerplant for this type of plane.

Cheers to Hyperflight for not only providing incredible service all the way to California USA, but also for the extremely well laid out, informative website that shows prop and battery recommendations for all these motors. It makes life much, much easier!

Great Motor! Great Service from Hyperflight... The combo is A+ I'm using a 4S 650mah pack and a 10x5 GM prop. It pulls my 73oz Infinity (F3J wings on a F5J fuse) vertical. The bench measurements are 546 Watts and 45.2 Amps. I really like this motor.

Great motor, in my Storm 2PK. 11x6 prop 3S 850mah has all the power you need.

Good

Motor fits nicely in my 4m Enigma...a nice, clean set-up!!...Top rung service from Neil!!!!

On the bench draws about 50A on a 11x6 GM prop, 4S 850mAh LiPo. In the air will pull my F5J (1350g) as good as vertical. Shorter than a geared motor (so allowing battery to be further forward), fits easily in a 30mm nose, wires out the rear, no gearbox maintenance, smaller prop that geared motor so lower drag when gliding, and all at a fraction of the price of a geared motor. I’m very pleased with mine and assuming it lasts will not be going back to geared motors.

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.

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.
