CC/Neu vs Losi Xcelorin vs Tekin T8 motors

Both take off exactly the same. If you didn't know, you wouldn't be able to tell which motor was running, aside from the slight top speed difference between the two. The tekin 1900 kv on 5s is definately more powerful and runs cooler than the 2650 on 4s.

Hi,

I have the losi 1700 kv motor for about 7 months now. I have written a review in the forum.

After many great runs there are only a few negative points about the motor:

1. The screws of front/endbell can break (!!), once its broken, it's hard to get the bloody rest of the screw out of the endbell.

2. The kevlar-wrapping of the rotor can get damaged by dirt, which gets into the motor by the various mounting holes of the front endbell. They say that you can get a replacement rotor with the better carbon wrapping easily.
Well, not here in Germany. There is almost no support. The distributor in Vienna (responsible also for germany) first has never heard about those rotors, later never got some. I tried to get a new rotor, impossible.

Finally I have put super glue on the kevlar to avoid more damage, did that for 3 times, and sealed the not used mounting holes. it works.

3. As the losi 1/8 stuff is not that common here, it's almost impossible to get the proper heatsink. And if, it's far too espensive. I use two good fans, temps are ok like that. I won't order just one single piece in the us... that's senseless. like that temperatures are between 45-60 degrees c/113-140f. only a few times got over 70 deg. c.


But there are many good points about that motor.

1. It has plenty of power and torque. The rotor is balanced. As I now have a torsen center diff, I had to reduce (!!) timing down to 1 degree, otherwise it's too much power for the buggy. and I have already added weight to the front. With the normal center diff and 100k oil I used 7 deg. timing, and it was plenty of power. What I really like, is the massive torque of the 1700 on 5s.

2. It has massive bearings, the front is in a very common size and easy to replace (had to replace it twice due to sand and dirt). And I like the M4 mounting holes.

3. Except those stupid screws, overall quality is very good. Power is excellent.

4. Price: you can get the motor for around 85-90,- euro (120 usd), which is ok.

I only can speak for the 1700kv motor, I think it's just a great motor, but highly underrated. Losi is doing a bad job in regards of PR. Losi electronics have a bad standing here in europe, as their 1/10 stuff seem to be cr*p. Further, the xcelorin 1/8 esc is not available for months now. Losi electronics are not "sexy", compared to cc - mmm. There are so many - especially just recently and w/ 6s - blown mmm here in Germany. Still, people think it's great stuff etc. Well, they say they have great customer service; I think they have to, with all these problems... but thats off topic.

I think I am one out of a few here in germany, using a losi xcelorin motor. The other day I was competing (frankenstein's ride - hyper 7) a little bit with some guys with hpi bayas, on soft/sand ground; at least I was same fast (or even faster)... I would buy that motor again.

BUSAFIED, how do you have cogging coming out of a corner?

[E-Revonut]

I have no personal experience with any of the combos. I have a mmm and a 1515 2.5d and a Medusa 36-70-1600. From what I have seen on the track the Losi's don't have as much power as a mmm combo. For awhile i was being classed with the buggies and I could pull on them anyplace on the track. They where a bit more precise drivers than me but I was still running top 3 each time I raced them

i have no knowledge of these motor either so i was reading through and checking them out and i came across this. Would this be another option or even in the same class

it doesn't happen often, but it does happen to me. I think it's more attributed to my AWESOME skills of tapping the brake too much in the corner (in an attempt to get the ass end to swing around) which then results in my corner speed dropping down just about nil.

in an attempt to get back in the running, I goose the throttle to about 75%, which results in a frustrating surge-cut-surge behavior.

and it always happens at the same turn, too.

Yeah, those Tekno motors look to be the same class. They look pretty interesting too, though without the Tekno conversion kit, I have to drill the chassis. Should be really secure though. Their 2200kV motor looks interesting.

Looks like the HPI Flux Tork motor is about the same price range also and it's identical to a CC/Neu aside from the heatsink can (finned on CC/Neu, separated finned on HPI).

So, CC/Neu 2200kV, HPI Tork 2200kV, Tekin T8 2250kV, and Tekno 2200kV. Damn, wish I had more money. I'd love to be able to try out all these motors!
