first look on xcelorin 1700kv-motor
 

after I have tried & fried some motors in the past months, most of them cheap but useless (except the 36-88mm brick, but the magnet got loose again...), so I tried the xcelorin.

I chose the motor because of the availability in my lhs, the good price of Eur 99,- , it's a 4 Pole-Motor, which means better torque, quality seems ok and losi says "90 % efficiency". it also has mounting-holes for 4m-screws.

The buggy is a cheapo-thing called "ansmann Virus", biggest problem are the diffs, the diffcases are too soft. I finally found an alternative, I have now the diffs of the hyper 7, which fit perfectly. the buggy seems like a rip-off of a hyper 7. but anyways.

I used the new motor on 5s lipo a couple of times, the diff has 12/43 teeth, kyosho plastic spur gear 46 teeth or so, and crime-fighter truggy-tires. esc is a chinese-no-name.

like that the temperatures were around 40 to 50 degrees on the motor, and a bit hotter at the pinion. I use a little fan to be on the safe side. it's pretty cold here at the moment, tought. highest temp on the esc w/o fan was 50 deg., with fan 30 deg.

Yesterday I had the hottest temperatures, around 69 deg. c. on the motor, 50 at the gear, after a whole run; the fan didn't work. it was like permanent full throttle-breaks etc. high grip. same gearing (/13t), but a newly shimmed front diff which is not that smooth at the moment (that will change after some runs. Due to the torque I dont want a loose fit in the diff). this may be a reason for the higher temps, I dunno. weight of the buggy-truggy is 4,5 kilo total.

Most times I had the lowest timing possible on my esc, 1deg, also tried 8deg, which caused less cogging, and probably better temps. I need some more runs to find out. the "felt runtime" on a 4400mah 18,4v lipo was good.

Probably I try a 14t steel pinion, I am just a bit scary after I killed some chinese motors. with 13t accelaration is great, wheelies possible, topspeed guessed (low grass, winter, no snow) +45 kmH. I have read and also experienced that a higher gearing could cause even better accelaration (and higher amps too).

performance overall is good so far.

When I think of yesterday's "abuse" the high temperatures of 69 degrees w/o fan are ok, but have to be lower in the long run, definately. any suggestions are wellcome.

has anybody an idea who's the manufacturer of the Motor?

Good review. The motor is made by losi.

thanks. it seems that it's a solid motor so far, for good money. The question is, who is the manufacturer? I don't believe that losi is producing the motors, they have a manufacturer, just like for the esc's. So I wonder who it is.

I'm curious if 14t instead of 13 would be still ok regarding the temperatures. But ther's no way for bashing at the moment here, wet snow... eeeh.

Losi is not producing the motors. Im almost positive its the same people that are producing their other systems.

The motor seems ok except for the bearings. The 1300 I had ran good for a little while, then the bearings went bad. Took it apart and they felt like worn out clutchbell bearings. Replace the stock ones with some good ceramics and the motor would be great.

For the price, I would go with CC or Medusa over losi. They both have a proven design and track record.

that might be right for the us, but not for europe: for a total cost or Eur 99,- I would never get a medusa or cc here in Germany. ordering in the us in most cases I have to pay customs and taxes. f

or that price I don't find an alternative motor, and feigao etc. aren't an alternative.

Don't see why you can't pick the CC stuff up in Europe though, the distribute there.

I dont't know if I get the cc-Neu-Motor only; I've seen -so far- the combo mmm for 289,-. Euro.

I had another ride today, still full throttle, but a bit less "insane" then last time, highest temp was 45 deg. on the motor, 50 deg on the pinion. I used a higher timing of 9 degrees. like this, power is absolutely sufficient... let's wait till its warmer outside. interesting point is, that the temperature is falling to 40 deg. quickly when I have a quick stop.

so far I am happy with the overall performance, for the money payed. losi belongs to horizon hobby, and they just have opened their business in germany, so the horizon, losi stuff etc. will be easier available here then cc. But reg. cc I might be wrong, as I never really thought about buying a mmm.

If its 289 euro's= $370 USD I would take a look into local stuff such as lehner, hacker, schulze, plettenberg kontronik etc... For $370 usd thats quite a bit in my opinion.

well, the brands you named aren't cheap either... these are more or less the high-end brands. I'd love to have an pletti or lehner, if I could afford it.

True.

Your temps are fine. Wait until its 80 degrees C. Then you'll have to worry.

yeah i was about to say germany is the motor capital of the world! what are you doing with a chinese made losi. i would have spent the money and got a hacker or a lmt. or a beastly plett.

many thanks for the replies. as for the hacker, I think I have heard that they get their motors manufactured in china, too. so many consumer goods are made in china, "china" doesn't always mean crappy. aren't the cc-Neu motors manufactured in china? regarding the magnets it seems that china is the main supplier; the german brand "flyware", who have some great motors too, get their magnets in china. but that's OT...

I'll have a further ride today, wheather is getting better, but so far I have to say the motor is worth its money. on the bottom line, it's more "expensive" then a bidproduct or UH motor, but by far better (bearings, heat, performance etc.).

regarding the temps, I'm still careful, but it seems that the temps are ok so far.
