Blaz, I got it back in January from Amain Hobbies, they had it on sale and I was able to use a $25 off coupon as well.

Got my replacement rotor from Tekin, excellent customer support.


This is the separated magnet


Old rotor


New and improved rotor.

Improved? In what way (just curious...) Aside from how it looks...do you know what the change was and why...

And the important question - have you driven it yet?

In my opinion the use of the large aluminum spacer instead of tubular steel spacer gives the bonding compond/glue more surface area to better hold the magnet to the shaft.

I got the buggy out on the track this weekend and it ran very well. Temps looked good. Got around 20 mins out of a 5000mah 4s lipo.

I had an unusual breakage this weekend. I broke the front inner hinge pin plate. The Losi hinge pins are captured and held by plastic plates on each end. I broke the inner plate and this allowed the hinge pin to slip out and cause the a-arm to fall off (and take the driveshaft with it). I can 't understand how this part would break, could have been from a hard frontal impact that pushed the pin back far enough to break the plastic part, but the front hinge pin plate (plastic and aluminum) parts looked fine, no bends.


Part is broken near the screw that is sticking out. The screw is sticking out because I was going to remove the plate but decided to take a few pictures first.

man I got an extra rotor but it didn't look like that.

Don't get me wrong, I love the way my Losi's handle but the quality of the plastics leaves a lot to be desired. I've snapped an ear off the diff case so I'm betting your issue is just some brittle plastic and as you suggested, the hinge pin may have pushed it a small bit.

Every time something breaks on my Losi's, I try to replace it with a King Headz part.

Dave, you read my mind. I ordered a King Headz alloy hinge pin brace on Monday and it arrived today.

Here is the King Headz replacement, beautiful machine work. I don't expect it to break like the stock Losi plastic part. I also noticed that the hinge pin had wear marks only on the ends, which means the pins mostly rotated with the a-arm. This tends to wear out the hinge pin plates, but the King Headz part has small set screws which locks the pins so the a-arm rotates around the pin, the a-arm has far more bearing surface than the hinge pin plates and the suspension should stay tighter (less slop) longer. I guess it wouldn't hurt to ream out the a-arms as well.

I've been racing my 8ights for a while now and for the most part I've only ever broken were a few front kuckles (plastics). Everything else has held up like a tank... I don't have any issues w/ the losi plastics. I think the only other problems I've had was when a shock screw backed out on the inside where it screws the disc onto the shaft and I have warn out a few front center drive shafts (where they hit the center diff output). knock on wood (knock.. knock.. knock)
