the 1700 I had is at least as good as my 3680-1600 medusa racing. the medusa is good, but the losi has better features, like the massive bearings. both motors are used on 5s, plenty of torque, but I think the type of torque the losi had is kind of better. hard to describe, but it felt better.
and yes, 4-pole motors need load to perform well, otherwise performance is poor and the motor gets too hot.
go for medium timing, at least. you will experience a BIG difference in performance. believe me, I had that experience too. 4.pole motors require timing of around 15 deg.
motor got a little hot without cooling, you need a losi-heatsink.
they are great motors and under-rated, as people only buy stuff that is well known and common... like that 2200 cc neu...
