Anyone tried the Losi 1/8 Xcelorin 1300kv motors yet?

Hmmm.... IMO 6S 1300Kv 40mph in a 10lbs (or more) Erevo isn't undergeared at all...
We tested this motor in 1:8 buggies, geared for 40mph, and it's heating very fast compared to other standard motor, so it's not a surprise if it heats in your Monster Truck. Gearing up will probably fried it, watch your temps man, and buy a temp probe!

18/52 is geared for 32mph on 6S in the E Revo.

With 4 pole motors, it has been my experience, that best performance comes when you put the right amount of load on them.

Undergeared, the motor just tops out.

To take advantage of the added torque a 4 pole makes, higher gearing is required.

I'm really looking for performance comparable to the Medusa Motors that I've played with.

I had a Medusa 36-60-1500kv in this truck geared 22/40 on 4S and it did GREAT!

However, there could be a big efficiency difference between the two.

Motors are not all created equal, that's for sure.

thanks for posting MY pics above...

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...

Yes, these are your pictures. Very good pictures I might add. I hope you didn't mind me posting them here.

Medusa makes a very good motor and I believe their downfall was the 2 year warranty with such small bearings.

I do need some sort of heat sink, but the losi heat sink won't fit the E Revo application. Maybe if I hacked it up, but don't really wanna do that.

There needs to be more heat sinks made that fit this size motor.

I still haven't found the sweet spot for this motor. I will try again.

no worries mate. yes, the bearings of the MR are a joke, had to change the bearings twice.
I know the heatsink-problem too, so I took a fan. Like that the temperatures didn't exceed 60 deg. c, which is quite ok. I have heard that the cheapo-style heatsinks fit as well, or you can make them fit.
