    T-Motor F90 Pro and 60A Cobra ESC

    in Speed Junkies!

    I recently tested a new 6S power system for my FF-Demon foamboard RC plane. I was looking for something to push the plane over the 100mph mark. Frank recently tried the T-Motor F90 Pro drone motor on his Strix Goblin RC plane. After seeing how it worked out on that plane I decided to try it on the FF-FF-Demon. The F90 motor I used is a 2806.5-1300kv motor. Note it is also available in 1500kv, version which I already have and will test in the future also. One other thing to note, drone motors usually do not come with an X-Mount. So you may have to source an existing one, buy one or make one. I had some old motors with X-Mounts and found one that fits. The F90 Motor has mounting screw holes at the 19mm x 19mm diagonal spacing. For the ESC I used was a Cobra 60A Race Wing ESC with the BLHeli Firmware. For the Test I got a couple of cheap HRB 6S 1800mah 50C batteries. Props used were APC sport props, sizes 7x6 and 7x5. I was pretty happy with the results. The FF-Demon hit just over 120mph, though with a good tailwind. I think that is pretty fast for a simple foamboard RC plane. I plan on doing some more tests with a few other props, maybe something like the APC 6.5x6.5 Pylon racer Prop.
