This is a great little motor. Underpowered for an 800mm warbird, but still a great motor. (Posted on 3/18/2014)

Very versatile. Great for slow flyers or fast zoomers! For slow flyers use a 9X4.7 and for fast flyers use a 7X5APC. Great price too. (Posted on 3/3/2014)

These are tough little motors! and pretty fast too! I use them on my flying wings made out of EPP foam weighing around 16 to 18oz's. the only gripe I have with them is the little grup screws in mount holding motor bearing tube will come loose after a few flights. easy fix with some blue thread locker. good value! you can buy alot of them at this price!

Just love this motor use it in almost all of my planes,(Dapron EPP wings) scratch built it seems to run for ever only one draw back is if you have a hard nose in or crash and the esc gets pulled loose the windings can pull away from the can and break and the shaft is kinda soft you can get replacements the good news is that I (you) can rewind these over and over and they work just as good or better than new so for the money get a few and give them a try also get the 2822 as I use those as well.

These are great little motors for the money and can take a pretty good beating. It works great for the mini Gremlin with a 7x5 prop . I really get some long flight times with a 800 mah battery. (Posted on 11/16/2012)
Great motor for a small price Review by Trent

This is a fantastic little motor - perfect for 34" combat wings (Crash Test Hobby's "Assassin")
Rewind them with 9 turns of 24 awg MicroDan motor wire and get 300 to 347 watts output with a 7x6 prop @ 31 amps with a 3s 1300 mAh battery.
Stock they are around 200 watts at 20 amps with the 7x6 prop. What more could you want from a motor costing under $10.00?? (Posted on 10/25/2012)
Great motor for a mini Popwing! Review by Ron in Las Vegas, NV

Overall
I bought this motor to replace a motor that burned up on my Techone Mini Popwing. I was looking for something that would work well with a 25 amp ESC, 6x4 prop and a 3 cell 1000mah lipo and boy did I get what I was looking for. This motor is excellent on my wing! Although it's not a screamer the speed is decent compaired to the HXT motor I used before but the bonus was unlimited vertical. I had my wing so high that I couldn't see it anymore and it took about 3-4 seconds after cutting the throttle for it to come down enough that I could see it. I get 8-10 minutes of flight time on a 1000mah 3 cell 40c lipo and the motor comes down slightly warm. The ESC is cool to the touch. I will definately be buying a few more of these motors.

Hard to beat for the price! Review by Lewis Slawny

Theese little motors have been a blast to use! Low power consumption, Low cost, These make great combat plane plane motors, If you like working with depron or other foams, or even smaller park flyer arfs you will get hooked on these in no time. I have two of these one is on a 13.5 oz. pusher jet with a 6-4 prop and at wide open for the entire flight the 1000 mah batery and motor are barely warm. Oh and by the way that set up is probably a 35 to 50 MPH plane that keeps up with most of the nitro planes at the field. I have really been hard on this little motor and after 100 plus flights still works like new. you do the math. (Posted on 9/8/2012)
