UH OH, he let out the smoke, not good. Does not sound good at all, but he did not post any specs as to how he was running it either. He may have been trying to overwork the system in his setup. The design and idea look interesting though. If you get it please let us know what happens with it.

Chris Long is our buddy Arkt1c.

The motor is too small for a truggy, and too low kv for 4s. It appears to be an align 600l knock off (at least design wise). It should be good for a buggy on 5-6s lipo. I have an align 600l that I plan to run in my recently acquired hyper 8 on 6s lipo. Should be a beast.

If you want a good inexpensive motor for the truggy, try out one of the kb 45 motors, the 8l at 2300 kv would be a beast on 4s. I have a 10l, 1800kv, in my ultra gtp and it makes tons of power on 4s and does not get hot. My MM also stays very cool too, like it is not switched on! The only issue is that the kb motors have a 6mm shaft and a 30mm bolt pattern, but I made my own motor mount so it is not a big deal to me.

True, he didn't post his specs or what he was trying to do, but I thought I'd at least warn about the possibilty of failure. Also, he said it blew within 4 minutes of running. I would think he'd have to be REALLY overworking it to blow that quickly. The specs list power as 1200w+ and the kv, but not the max rpm. 1200w should be enough to power a buggy, but the specs could be inflated. And being an outrunner hybrid, I wonder if the max rpm is lower like most other outrunners? This would really limit the usable voltage as well.

TBH, I don't see the reason for a out/inrunner hybrid. Doesn't an outrunner have more torque because of the lower kv and amp rating, rather than the high rpms that an inrunner is capable of? An inrunner can be cooled easier because the coils are physically attached to the can, which makes adding a heatsink pretty easy. To me, it seems like a hybrid actually combines the disadvantages of each motor type instead of combining the advantages.

All in all, it would probably make a good motor for a stadium truck or other 2wd vehicle that is 1/10 scale or smaller.
