Scx-10 transmission Q's

[black-hawk]

I have a 2wd trophy truck that I built, and I wanted to put a faster transmission in it (I have a 12t brushed 550 with a 32t pinion, and a 2s lipo) I was wondering if anyone had ever put like a 40-60t spur gear on a scx-10 transmission. I want a lot more speed. Would it burn up my motor?- The other idea I has was to get an traxxas slash. But I think the axial transmission is a lot stronger. Any suggestions?

if you want that much speed you're better off getting a slash...Crawlers and trail trucks aren't meant for super speed.

The associated trans is a 2.6:1 ratio I think
Not sure what a slash is.

I know English is hard but try reading his post again. He wants to use the scx TRANSMISSION in a 2 wheel drive trophy truck. Not turn a whole scx into a trophy truck.


Yes the scx transfer will hold up well since it is the standard 3 gear design as most other 2 wheel drive off road racers. The only hurtle will be attaching axles to the 5th outputs that will match your current hub carriers. If you can figure that out you're home free.

Not following you on the last part. But my rig is a rear solid axle. I'm running a wraith axle, with a rc4wd steel driveshaft it will connect straight to the transmission.

Yea..you're about 3 minutes late to my edit.

I think overall ratio will determine rather or not the scx10 is a better trans or not for speed...Do you know the stock ratio for the stock scx10 trans????..that might be more helpful...Maybe its not worth figuring it out if the ratio wouldn't make the truck faster.

If that's the case then it'll hook up with zero issue. I was thinking you had built an independent rear suspension truck. Maybe English really is hard.

Apparently. :P

I don't know what kind of trophy trucks you have seen. Every 1:1 trophy truck I have Seen has a solid axle in the rear.

I have a build thread. You should go check (chevy prerunner/trophytruck, somthing like that. It's in 1.9 scale threads.) out. you would get a kick out of it I'm sure. It's not what you have in mind at all.

I just wanted to know if I had a smal spur and a big pinion 12 t motor if I would brake motor or the trans. I found a video on YouTube (it's called. Fastest scx10 honchonator- axial scx10 trail honcho.) the guy has a 69t spur and a 35t pinion. Doesn't say the motor. And that thing is crazy check it out.

Using it wouldn't be the hard part, just use one side to output power. It's just all this whacky gearing talk that may become an issue.

If you want speed, it's time for brushless. And since it's a trophy truck it shouldn't require much slow speed control. Luckily sensorless is cheap. Up the voltage and acquire a faster motor.

Oh yeah, build up that Axial trans as well.

According to Google the ax/scx transmission has the same 2.6:1 ratio. Those trucks go slower due to the added reduction from the axles being added into the final drive ratio.

Never heard of Ivan Stewart or Toyota Racing Development eh?

Build you a setup like my sand drag car , cept you don't need a front output . It'll go faster lol .

Does the motor pinion go to the spur that goes straight to the axle?

[hellbounder]

Yes sir

[hellbounder]

There's a thread in the foff section but it still has a way to go . I have a 2 year old son and a wife about to pop with my little girl . So I had to stop on it for now .

The chassis fabrication is just solid design and good work but that cv setup is off the freaking hook.

Some good talent in Australia :-)
