Benefits of MOA

[TFitzPat87]

Hi Guys, new to the RC/Crawling world, and just curious on what is beneficial about running MOA? Also does MOA mean it HAS to be a dual motor setup (one on each axle)?

I'm just trying to wrap my head around all this different stuff. I don't understand what would make a difference if the motor is connected to the trans vs. it being on the axle. Wouldn't the power output be the same either way? I can see it keeping a lower COG, but what else?

Thanks in advance!

Variable overdrive is a huge advantage.

Lower CG like you said.

Narrower chassis options.

Faster dig

Others will chime in.

And yes, MOA is two motors. One on each axle.

No transmission, motor geared directly to axles, no driveshafts to hang up, overdrive/underdrive completely variable remotely, and two motors not one


Hang up and Drive

Moa is designed for competition rock crawling. This means extreme obstacles the majority of which most chassis mounted trans cars wouldnt be able to complete. I have seen moa sxles on scale rail chassis with scle bodies on them and the result is better climbing performance over the traditional chassis mounted trans.
Thats the quick amd dirty version.

Check build threads in axial xr10, en route berg, and rc4wd bully and then compare them to scx10 or wraith.

And if your really feeling saucy compare them to the ax10 scorpion and ax10 gen 2 builds. These are shaft driven competition crawlers.

MOA = motor on axle... I've seen a few custom MOA axle based rigs modified to run 1 motor and drive shafts. Trying to fit into the 2.2s competition class. At the time they meet the spec of the class but rules were changed.

IMO a MOA/competition crawler is just more fun to drive.
MOA class rig 2.2M (modified) and Super class. = motor on axle
2.2S (sporty) class = single motor transmission and driveshaft.
All are competition classes and can be very capable rigs.

Scale rig 1.9, 2.2 class = 1 motor drive shafts rails style chassis ( vague description) trail type style crawling and guys to compete with these rig @ scale comps.

Like curcal said read build threads in section mentioned above...

Cool, thanks guys! I'm sure I'll look into those builds. I'm currently finishing up an SXC10.2 XJ, I can't even drive it yet (waiting on ESC) and I'm already addicted. Just trying to build my knowledge and see what I may want to tackle in the future.

On a completely unrelated note, where can I go (website wise) to find out about possible comps in my area. My XJ is gonna be mainly for personal fun, but I'd like to check out or try a comp and see what its like. I know most newbies like myself complain about comps being too difficult, but isn't that kinda the point? Crawl with the better drivers/rigs and get better by practice and taking notes? It's not like you pick up a basketball and can play in the NBA the next day.
