1/8 Buggy w/ a Outrunner Motor

[jhautz]

I did get a little more testing done this week with the outrunner. I ran 2 more packs with it and 2 more packs with the Neu 1515/2.5D. All in all it ran pretty well on the outrunner, but it didn't quite have the snap and responsiveness of the neu. The spool up made it feel a little sluggish on the bottom end. I think I am going to wind up sticking with the Neu and the Quark 80B as the final setup.

I forgot my eagletree but using my Watts Up meter I saw amp spikes of around 120A on the Outrunner motor and around 112A on the Neu. I'm kinda surprised that the outrunner was drawing more considering how much bigger the neu motor is.

I also made a few changes to the setup to accommodate the Quark. I made an ESC mount/heatsink out of aluminum L stock and put a haetsink on the side with a small fan. Seems to work fine, but when is 40 degrees outside anything stays cool. We'll see this summer I guess.

Anyway... Heres a few photos of its final (for now) form.

Pretty sweet!

You must have been anticipating using some rather large pinion/spur combos judging by the length of the adjustment slots on the motor mount!

It was actually a mistake part that was left over from my XLB project. :rolleyes: The XLB Runs a 65T spur so It needed a little longer mount. I was able to salvage it and make it work for this application. Your right, Its way longer than I need, but I already had it. I just needed to drill a couple screw holes into it for mounting and I was done. So I took the lazy route rather than starting from scratch again.

Lol, that makes sense. I just thought you got carried away with making the slots. :)

BTW: I don't like the term "lazy". I prefer "efficient". :)
