Stretched e-Muggy (Baja-style) Build Thread

[brian015]

I finally got a chance to weigh this thing today, and with batteries it's 18.8lbs. Slightly more than I was expecting, but I was in the ballpark. My Muggy weighs 12lbs with batteries. The chassis, wheels/tires, and extra battery cells are the biggest differences between this and that (also motor and esc are a little heavier).

I landed a jump today a little on the nose and a front spindle broke near where the turnbuckle attaches - this definitely looks like a weak spot. Anyone have any luck with aluminum LST2 spindles?

i've got a muggy with 1/2" offset hex and alu. spindles and all good so far,And another with 1/2" offset Jconcept wheels standard hex also good so far. I think yours is a bit heavier than mine,and cooler.

I do think I'm pushing the limits on the LST parts with this much weight - but I have no real complaints other than these spindles. So I hope the aluminum upgrades are better - thanks for the input.

I haven't been driving my Muggy this summer - having too much fun with this one. I think it's going to feel small when I get it out again.


@Dj_Sparky - I saw your question about the motor and I guess you found it buried somewhere in this thread: Neu 1527 1.5y (825kv)

What size spur and pinion are you using?
