Default MOA with dual HobbyWing QuicRun WP crawler brushed

Hi

Has anyone tried \ heard about some one trying to use a dual HobbyWing QuicRun WP crawler brushed to drive a MOA?

the price and feature set are attractive, so the only issue is weight, space and actual real life performance?

would appreciate any first and second hand experiences

Thanks

This ESC is powering my stock Clod Buster. That's an MOA, but not an MOA crawler.

did you run both motors from single ESC?

Yes, but you have to watch because the ESC has a motor turn limit. If you're running it in a crawler it should be fine. I'm not sure it would be as adjustable as you'd need for an MOA crawler though.

Do a search in the rc4wd bully section. There is a few people who have used that esc (turned into dual esc) in there bully 2 rigs.

I'm talking about the dual motor brushed ESC from HobbyWing.

I have a berg running dual 1080s. Big & clunky for the application and the stupid proprietary 5 wire switch that I can't just cut off like all the rest I own sucks but they get the job done without issue. Running 3s and 45 turn fantom motors geared up.

I don't think it has a dig function. That's important to me.

Any esc that uses a dig switch is junk. Dual escs and mixing channels on the radio is the only way to fly.

If you run 2 motors off 1 esc & the esc doesn't make it clear what a dual motor limit is, it's generally 2x the turn limit of 1 motor. Meaning if it says single motor limit is 12t, a dual limit is 24t. Motor amperage usually scales well (inversely) with number of turns.

When it comes to MOA crawler, dual ESC gives you abilities like dig & pushing the load to the front wheels (higher wheel speed). It can increase crawling ability by reducing the tendency to try spinning/turning when the front lacks grip. For bashing it would only decrease motor limit while adding weight & complexity.

Yup...


If you are going to do it, do it right. You can get away with running two motors with one ESC, but you will have a big problem with clod-stall, basically when going up hill your back wheels will have more traction than your front wheels, there is less of a load on the front wheels and that is where all the power will go (path of least resistance).

Most aftermarket radios will have a MOA crawler mix function that will allow you to set up two ESC off of your throttle, and provide a proportional dig function as well. The ESCs you use should have a instant reverse and a good drag brake.
