Default SCX10 with Slash Motor

I know it's been done before, but whatever.... ;)




EDIT: Here's another video after I modified the chassis for my Jeep body

Looks so much like a real dragster taking off at the line!

I had my slash motor and esc in mine when I first built it, just to get it on the rocks. Thing hooked it up. Raced my buddy and his fast turn motored SCX at our local track untill I took a jump to hard and hit the outside front tire at full lock and destroyed my servo.

That's with the stock 14 tooth pinion, 3s LiPo, and Sidewinder ESC.

that race was pretty fun wasnt it...lol yours was just a bit faster....btw mine was a 27 turn motor but i think that i was running a smaller pinion than you...

I've since installed a Jeep hardbody and shortened the wheelbase to just under 10.5" and it launches much straighter now. Though I believe the improvement came from better suspension geometry, a lower ride height, and installing firmer rear foams. I also geared it up to a 15 tooth pinion, which I think is too big for my purposes.

I posted this in my build thread, but thought I'd post here, too, for those who may be interested....

Well, I've decided against the Slash motor. The reason is fairly simple. It just doesn't offer enough finite low speed control. And it's accentuated by its lack of torque. In some tough spots it will stall until it starts drawing enough current and then it'll surge forward too abruptly. Other times, it just doesn't begin crawling slowly enough. In other words, it requires too much throttle to get it going and then you can back off and crawl slower. It actually reminds me of wheelin' a 1:1 rig with an automatic transmission. When it gets into a bit of a bind it'll require more throttle and eventually the converter loads up and then can "shock" the tires into spinning just a bit. It can make it very difficult to very slowly crawl an obstacle and it's why I have three pedals in my Jeep! Granted, a much smaller pinion could help, but then it would defeat the purpose of the higher speed motor, IMO. In addition, for a crawler, this is just an unrealistic amount of wheel speed and that's not what I'm after.

And all this is after I altered the curves on my speed controller (Sidewinder).

So I'm going to look into a 35T or maybe a 27T motor so I can still have some wheelspeed, but it should provide enough torque and progressive throttle control to keep me happy. The Slash motor will see use again, though. My next project after the 6x6 trials truck will be a dual purpose pre-runner/rock crawler. This motor will be great for it.

The slash motor has had more than enough torque and slow speed control for decent crawling. how hard were the lines you crawled with it?

I have been thinking of putting my old slash motor in my SCX looks like it could be fun. As of now i got a old trinity 27T and it has enought wheel speed on 2s that it makes it quicker on the flat sections between obstacle's I'm gonna go 3s once i pick up a new esc. IT has alot of low speed torque and doesnt studder at all.

They were pretty challenging lines, but it wasn't just on the really hard stuff. In any situation where a little more throttle was required to crawl an obstacle, it was not able to move with as much control as I'd had with my 55T before. Is it horrible? Nah. But it's not as good as I want. In an easy scenario like just crawling on smooth pavement to see how slowly I can crawl it does fine. But on steep ascents or in a bit of a bind or at a ledge and it just doesn't perform the way I want it to....for this truck. ;)

Nice. Never would have expected the low speed ability if you had only SAID it was a 12t

Makes me want to install my Xcelorin 4800 in mine.
