why not go quad 6374? 12s, 50v*50A = 2500 x 4 = 10 KW! or 14s LiFe 26650
and you can use a quad vesc…costs about the same as those escs…
either way can’t wait to see it! 
i was thinking to mount this on a ebike ! , then i got hooked on skateboards. do you want to go dual with this ?? ( i mean we have seen 2 outrunners wich provide about the same as one of these so, for sience ! ) would be sick to see 2 of these chain driven and geared for wheelies on a trampa !
to be totally honest I first wanted to go the leopards 175kv quad but that was going to be quite a stuff around. So I was going to go quad of these. and well thought 2 was going to be mega overkill and honestly not sure they would fit two side by side. The gearing I Think will have to be quite large due to the design of the motors .
@smurf It’s basically a very light weight dirtbike equivalent.
