Stretched e-Muggy (Baja-style) Build Thread

Considering the torque these motor produce, i wouldnt be happy with a hollow tube. i think the tube would twist before the ends brake off!

What is the process if you pay someone to do it?

Goodluck.

If I could weld steel, I'm sure I would have gone this route. As it is, I'm trying to do this project without paying for custom parts, so I'm using materials and processes available to me. If this Al tubing twists, I'll probably have to get something custom made - so thanks for the advice.

Here is a picture of the cross section of the tubing, just so people aren't imagining some thin-walled Al tube:

I hope it does - and I hope to get this thing up and running within the next two weeks (I should have the time to work on it) to see how it holds up.

So I actually had some time today to get this together enough to give it its first test run. I ran it on 6s geared conservatively around the yard. Everything worked like it was supposed to. A few things need to be tweaked but I'm happy. I like the mechanical brakes - easy to set up and worked well. I've never used them before because I never ran nitro.






And no, I didn't hit my wife with it (she was filming).

Good work man. One complaint. That vid is a bit of a tease! Was hoping for more speed, or more ripping it up with that big motor. Lol. Keep up the good work and keep us posted.

[brian015]

Sorry - have to wait until I get the rollcage fitted, then I'll let 'er rip

[bryan]

Lookin good keep those vids coming

Wow that's impressive work and really nice project! I may have missed it (hard to read thouroughly while my son is running around about to crack his head open), but what motor is that? It's ginormous!

I'd like to convert my 1/5 scale gasser to brushless. I love the runtime of the gas motor, but hate the pull start and having to tune it.

looks gd! let it rip!!! haha..

I'm looking forward to seeing what it can do on 8s and 10s!

I have the rollcage almost installed - a couple of more brackets to secure the center piece still needed. Here's what it looks like:





Another thing - I looked at the front tires after my first 15-20 minutes of running the other day and they're getting chewed up already. The rear tires look fine. I know the fronts are designed for the 2wd Baja 5b, but I wasn't expecting to wear them out so fast. I might try taping them to see if that helps - I know some people running the 5b tape their tires. Otherwise, I might have to run the rears all around.

nice cage... where did you get it from?

it's just the stock baja 5b rollcage - not too expensive on eBay.

I just put on some of the rc-raven springs and I think I'm going to like them. The yellow Losi springs weren't quite enough. These are stiffer and have much more room to adjust with the preload adjuster nut.
