My bad, forgot to sort that out. I was flying threw it and didnt have time to think. I was thinking that plettenberg was 6p to.

hi,

just recently I had to open the motor for cleaning. The front bearing broke, fortunately I had a proper one at home. Even that the motor is "closed", there was still quite a lot of dirt inside.



unfortunately the kevlar-wrapping of the rotor/magnets is getting loose, after 3 times of fixing it with super-glue it seems ok. So far I couldn't get hold of the new black rotor here in Germany (in the us you get free replacement).



the front bearing is massive, dimensions are 16x8x5mm, and sits in a approx. 4-5mm frontplate. I really like the choice of 3m- and 4m-holes for mounting the motor. the bearing in the back is a bit smaller (14mm or so diam.). The axle is 8mm strong. Like that it seems that they did their homework, it all looks very solid. I have read that newer motors are equipped with the better rotors, which have a black carbon-fiber bonding. they are supposed to run cooler, too.

I use 5s lipos, performance is great, very good torque. Temperatures are ok, on soft sand the temps are up to 70 deg. C / 158 f, during normal hard abuse the temperatures are between 50 to 60 deg. c / 140 f. I have a buggy (looks like a cheap copy of a hyper 7) with truggy-wheels. weight like that is about 4,3 kg, which is no problem for the xcelorin.

I use two fans, the original losi heatsink is hard to get here. I need the fans as my chassis-construction is kind of "sealed", to keep the dirt out. but like that (even w. holes in the karo) the heat just stays inside. The temperatures might be lower with a NEU, but I am happy so far.

A negative point about losi brushless is the service/availability: I orderd the losi esc, after one month of waiting the shop told me that the're not available (any more?!); you can't get a replacement-rotor, neither the heatsink. there is no presence of losi. like that they won't get a significant marketshare... the motor would deserve more. The problem is, when nobody buys the product, nobody will buy it ('cause it's no good, otherwise somebody would buy it...)...

for that amount of money (compared to other motors available here) it's - in my point of view - a great motor. I would buy it again.
