2 ESCs on one receiver.

Honestly I think just unlocking the front diff and controlling it with one esc would make quite a bit of difference. If you have dual drive in the front and one esc it's really not much different then an open diff either. The outside tire will rotate faster because it has less load on it, but it won't get stuck with one wheel spinning like an open diff.

You can wire the dual motors in parallel on one esc. If you don't like that you can alwayse add a second esc later. No clue on how to power one side less when your turning though, at least with rc electronics. An arduino could do that no problem, provided you know how to write the code.

Went with the open diff (one wheel drive) .. works fine as long as I drive it on a level surface, which I plan to anyway :)
 
For a small light esc maybe a quad copter esc would work. But you probably need a drag brake. Holmes and castle both have micro crawler esc's with dragbrake. The micro sidewinder 2 I think from castle. Br mini from holmes.

I guess both of these comments were too late to the party. [emoji14]

Late or not, its always good info .. thank you .. maybe a future project, but I do have leftover quadcopter ESC, but it is brushless. It is new and I have had it for about 6 years now, sealed, and yesterday I opened the bag to see if I can use it. It's a brushless ESC and not sure if it can handle a brushed motor, I know some can but am not sure about this one. However, I found some small crawler ESCs for 1/18 scale crawlers that hopefully will do the trick. Gonna have to wait for them to get here first :)
 
I was thinking the mini 380 revolver would be great for the forks. Not sure what size the motors are originally.

The motors that come with it are the ones I had in my Scalextric layout when I was a kid haha like so:

Is the revolver the one that makes that whining noise?
 
Yes, but it will kinda sound like a hydraulic pump I think. lots of smooth power for the size. I think the 380 might be to big though looking at this motor, just a guess.

Interesting. You have a good point, but sadly the gearbox/axle housing is one piece of plastic which, if I cut up to fit that motor, there no way it will all fit back ... if this was an SCX10 style chassis we'd be having a different conversation!!
 
Why not just replace the locked diff with an unlocked diff?

I have a strong feeling I will not find replacement parts for this let alone optional add-on parts :) But as I said earlier, I made the forklift one wheel drive and it is functioning well as it is, especially since I will only be driving it on a flat surface :)
 
this thread is completely lacking in pictures no pics than it dident happen

hahaha - got a build blog if you want a link - I didn't share it because it's like I'm trying to pull people from here to my blog.
 
This is the problem with the internet.... I have way too many projects right now, but reading this thread makes me want to buy a toy r/c forklift off of Amazon for $80 and try to convert it to use brushless hub motors. I need to finish other projects first, but I am really tempted to buy the stuff to do it.

You don't need parts for this vehicle, you can modify a differential for a different vehicle to make it fit.

hahahaha welcome to my world :) Go for it is what I say, tomorrow is another day :)
 
Yes, I understand you finished the project. I'm saying there are ways you could further improve it.

No the project is not finished. Waiting on ESCs but as for the drive train part I'm done and when tested I found it to fit my needs. Some more work needed on the steering though!
