Go Fast Transmission for Vaterra Slickrock?

[twomicros]

Hi All,

I have a spare brushed esc from an old mini-highroller and a spare insane 370 brushed motor that I've installed in my slickrock but due to overall gearing it's still pretty slow.

does anyone know of a more or less directly swappable transmission that can be used here?

I'm not looking for crazy speed, just a little faster than a straight crawler.

Thanks for any tips!

I'm not familiar with the transmission in the losi high roller but if it's similar to the losi mini T trans you can make some mounting holes on the slick rock transmission mount. Then take a part the slick rock trans to get the locker and output shafts out to install in the other you may need to do a little dremeling to get everything to fit.

I don't have the mini-high roller anymore. plus that was only 2wd so I don't know it it would work the same for this 4wd vehicle.

do you know if the transmission from a 1/14 losi rally or even 1/16 mini e-revo would work?

I believe the mini rally uses a pinion/spur at the center shaft and gets reduction from the diffs, not much of a tranny.
The locker from the Slickrock transmission won't fit in the Mini T trans. Hot Racing makes a locker for the Mini LST and Mini T but it is for dogbone-style diff cups (Hot Racing MLT38X Aluminum Locked Spool Transmission Gear - 1/18 Mini Vehicles | eBay). The Mini T and Mini LST transmissions have quite a bit less reduction (don't have the numbers sorry).

I used a Mini LST tranny for my 1/18 RC4WD Gelande D90. I'm using 9/62 gearing so it's not too fast but I believe it's meant for 22/54. I made some output shafts (3mm) out of stainless, maybe you could make something similar, but 4mm? Would definitly give you some wheel speed.









I wonder if you could just use the Mini LST 54t spur (Hot Racing Losi Mini LST Power Up 54t Steel Gear SMLT4854T | eBay a larger pinion to get the speed you need.

thanks for the info and suggestions! I have some spare mini spur gears leftover from when I used to have a mini-8 so I'll see if those fit. Maybe between the smallest spur and largest pinion I can find it'll give me some decent wheel speed.

essentially I want to make a mini rock racer kind of thing that can also climb over some trail stuff. it won't be anywhere near a straight crawler but I don't have any technical stuff near me anyways. I know that axial just made some 1/18 minis but the jury's still out on their quality and if they need to be upgraded.
