You should not need an ESC rated at more than 12A. If your present motor and ESC is not the problem is most likely the prop. When you are using a three cell battery you have to use a smaller prop compared to a two cell battery. Most every motor will have recommended prop sizes depending on the battery voltage. Hope this helps. See my review from 5/2/2014. (Posted on 5/19/2014)
Very impressed. Quiet, smooth, and strong. Hoovers my Value Hobby EPP Red Bull at 2/3 throttle. The Red Bull came out to a flying weight of 257 G. The motor is putting out 360G of pulling power with a 8.45 GP (similar to a GWS) prop, 7.4V, 800mA battery, and a 12A ESC. The configuration works very well for this plane. Getting about 12 to 15 minutes to a flight and I run it hard. All this and still only slightly warm. It is 1 1/2 times more powerful than my best 2204 motor at about the same size and weight for just a little more money. (Posted on 5/3/2014)
I fly this motor in 2 planes on 3cell 500 30c and 800 25c ,hobywing 10 amp esc no heat problems. Very nice motors comparable to twisted hobby motors at half price. I fly them in a twisted hobby crack beaver and value hobby 32in. Sbach.can't beat em. (Posted on 3/12/2014)
I bought this for use on Value Hobby's: 32in Sbach 342 ARF (8mm EPP) and on 2S its powerful enough for unlimited vertical with a 2cel 1000mah hooked up to an FMS 20amp ESC. I tried it on 3S but the motor/ESC/Battery all got hot, so I am left to assume the ESC was not up to task. I tried programming the ESC but it came with no instructions, and value hobby has no reference of how many amp esc is needed to run it on 3S. I doubt it needs an esc thats more then 20amps, so If anyone else comes up with an esc thats compatible to run it on 3S please write it in a review. Great motor, highly recommend due to its power.
