XPower F2915/12 XLight 1600 RPM/V 72g Cased Outrunner
Description
Eliminating the gearbox simplifies the powertrain and reduces the risk of failure. It also results in requiring a smaller (less efficient) propeller. In the past that was a disadvantage as powertrain efficiency was essential for good performance. However with the current state of technology excellent performance can be achieved even with small props, and they do offer several advantages, namely:
- Less stuff hanging out in the wind and less glide drag, so overall better glide performance, especially at speed.
- Usually a higher pitch speed is obtained, allowing very fast transitions to a low level thermal a long way away (if you are one of those god-pilots who know there the lift is).
- Smaller propellers reduce the effects of torque, making the initial climb out easier.

The Hacker A2022L (?) motor I installed, per plans recommendation, in my Inside F5J lost its smoke. I tried fitting another Hacker in there but just couldn't get the new one in, as the wires couldn't clear the slot without dragging on the rotor--probably the cause for the original motor short. Also, the Hacker rotor was scratched, indicating that there had been some contact with the nose block. I would have had to do some significant surgery to get the new motor in. The XPower outrunner in a case was the perfect solution--it just slid right in and had the same mounting hole pattern and I didn't have to worry about the spinning rotor touching the sides or wiring. Plenty of power and much cheaper than an inrunner/gearbox combination. It's about 20gr heavier than the original Hacker, but that wasn't an issue, as it was easy to rebalance the model. Worth the extra cost compared to the original Hacker. I should mention that the HyperFlight price, incl. shipping to the US was less than anything I could find my side of the Pond. (I hope current politics doesn't change that!) I have some possible F3J to F5J conversions that I might consider using this motor. In any case, I'm through with conventional outrunners!
Had a cheapish 28mm motor from a well know brand, never did like the 3 wires going back past the spinning motor in such a small space, so i replaced it with the XPower motor, not only is the very well made but the extra thrust is is well worth the few quid extra.
Great motor one of several purchase that make great service as usual thank you
Given the weight should work well in an F3J to F5J conversion project. Product was shipped quickly.
Good motor at a reasonable price, fitted in my Geronimo 2 nicely, being cased there is no way to trash the power leads
Purchased for my Arthobby Evolution. Fits in like a dream with wires coming out of the rear end.
Only need an 8 x 6 prop drawing 26 amps, and it gets my Evolution (1020) grams up at 11.2 m/s on a 900 mah 35c lipo. Fantastic.
I use this motor for the Joy F5J model. It fits the model perfectly (size and weight). To my pleasant surprise, with a VM 10x6 prop, this drive is surprisingly quiet, and the model can rapidly climb to altitude on a 3S battery. I am pretty happy with it so far.
The usual flawless purchase from Hyperflight. Everything as purchased with top service.
I put this in a 3.5m Yellow Jacket,
1230g.
I've just maidened it on the weekend with old batteries. This motor has plenty of grunt with the VM 11x7 prop. I'm well happy with my decision to use it.
