I assume the 570 on the E-F description implies a 570 kv motor. IF I remember my what my measurements were correctly. On the 15X8 APC in 40 plus degree F temps it puts out about 1000ish W. Draws about 60 Amps and turns the 15X8 around 7700 to 7800 rpm. All static of course on a fresh charge. I forgot what my measurements were with the 14X8.5. It flew the E-F Extra 300 with authority. Typical flights were safely in the 8 to 9 minutes range. I wish I didn't wreck the Extra. The next thing I was going to try was the new E-F 80 amp controller to save some weight. I was using a CC 85HV in the Extra.
Well, based on the measurement provided, I will need to add about 5/8" of offset to move the motor out to where it needs to be. The Torque X-mount aligns with the mounting holes provided perfectly.
You know, that sounds good after all, if it's 570 rpm/v, usually that high an RPM doesn't give adequate overhead amp-wise, but cleary that one says it can take 80 amps. I am curious about the size, adding 5/8" seems like the motor must be awful small, is it really shorter then a hacker A50 16S by 5/8"? Also, since it is shorter, you have the option of simply moving the cowl back, no harm (though watch the conopy clearance for removal)...

Just to clarify the part about the motor. I started out wanting to use a Hacker A50 16S (10 pole) which is equivalent to yours as far as rpm/v, I ended up not using it because I fried it in 2 flights in the Fliton Inspire 60 that I was using to test it, it simply couldn't handle the amperage (68 amps) and burned the windings (then the speed control, then the plane) :-(
