new Fusion E-1/8 buggy

Nice! What setup were you running in the track promo clip? Motor, esc, battery etc...

the old standard...

Mamba Max w/ubec
Neu 1512 1.5y (1900kv)
Maxamps 4s 8000mah (pair of 2s packs)
15/44

I did manage to get the MM hot this time. It's a bit heavier setup and I had no cooling hole in the body, no fans, no extra caps... and I was pushing it pretty hard. I got about 10 minutes in and it cut out a couple times for like 5 seconds.

I pulled it off so I didn't have to have the marshalls keep grabbing the car. I was up to 4th place at the time...

It only temped at 185-190 on the heatsink... it's been much hotter before without thermalling so I'm still not convinced that's what was going on. But that's the most likely thing. I think the motor was in the 160s. Normally the esc also runs about that.

One another note.. a friend ran my 8ight and had a blast. No issues... had a 1509 (1820kv) and MM with caps and a kokam 4s 4800. Another buddy was running his 8ight with MM and 1509 (2300kv?) on 4s and 12/46 and his temps were very good, but he was somehow using more battery than my 8ight. (@400mah more in a 6 min run)

If I had caps or better cooling for my MM.... I likely would have finished 3rd.

You sure it was the ESC? I had a very similar thing happen with my Hyper8 and it turned out to be the receiver rebooting because of the cheap UBEC I was running. Switched to a CC BEC and the problem went away.

BTW, can the CD take a Kyosho 46T spur? Might help temps a bit.

Very nice .
What are the dimensions of the battery trays ?

Should be @ 47mm x 138-140mm just like an Emaxx tray. But I've yet to see the production ones. Mine are homemade jobbies.

Any ROAR approved 1/10 type batteries should fit. TrueRC 50mm cells and the long Enerland cells won't work.

I'm going to try to get some special wide trays made to fit TrueRc and A123 packs.
