OS doesn't need me to sing their praises, but I'll do it anyway: the 18TM is a significantly more powerful engine than the TRX3.3, especially when paired with the optional single-chamber exhaust pipe that pushes the horsepower peak lower-down in the RPM range where it's actually useful when driving in grass. But it definitely is an upgrade, not just in quality but also in power. You might be thinking this is not an upgraded engine, because it displaces only 3cc compared to the 3.3cc that the stock TRX3.3 engine displaces.

I can always upgrade them later if I need to, but for now they work fine, even with the upgraded engine I had to install to haul this pig around in the grass:

So I opted to save a little weight and run the stock axles and hubs. In the picture above, you can see I'm still running the stock plastic driveshafts and wheel hubs normally I would've upgraded those to MIP X-CVDs and Team STRC aluminum hubs, but the Slayer is already heavy due to the large complex transmission in the center and the extra servos off to the sides, making this an SCT that weighs as much as some monster trucks.

Speaking of the suspension linkages, I fiddled with the lengths of those linkages to adjust the truck's maximum ground clearance, and eventually settled on a single set of 3mm spacers installed on the linkages (whereas the Revo has two sets of 3mm spacers installed), for the best compromise between ground-clearance in grass vs.

The 'old' Slayer had a shorter chassis plate with the correct wheelbase, but the trackwidth was still too wide fortunately I was able to cut-down the ends of the suspension arms by 9mm apiece, narrowing the trackwidth enough to clear a standard SCT body when running Pro-Line 'ProTrac' narrow-offset wheels, without the wheels scrubbing on the suspension linkages at full steering lock. Oh, and then there was the elephant in the room - the Slayer's oversized chassis that doesn't fit any aftermarket body shells. (I could've gotten rid of the side-bumpers, but one good cartwheel would've mangled the SCT body shell without some kind of side support.)Īlso the Revo and Slayer both have the weirdest throttle linkage setup I've ever seen, with the return spring on the outside of the electronics box instead of integrated into the servo linkage itself, so I cleaned that up too. Since the Slayer doesn't have a reverse gear, it doesn't need a shifter servo, so it uses different electronics boxes than the Revo, and of course they were different enough that the side-bumpers on the Slayer don't fit the Revo's electronics boxes - at least not without cutting the Slayer's side-bumpers to fit. Well.technically yes, but of course the devil was in the details. Buuuuut, the Traxxas Slayer shares a lot of parts in common with the Traxxas Revo, so maybe I could drop a Revo transmission into a Slayer and get what I want? There are no nitro SCTs with reverse gears. In fact, it narrowed-down the selection to.nothing. That certainly narrowed-down the selection a lot. But I've become spoiled and lazy by Traxxas nitro RCs that have reverse gears - and electric RCs that can reverse without even needing reverse gears - so I wanted my nitro SCT to have a reverse gear too. I've barely had time to think for the past year, much less play with my toys.Ībout a year ago, I decided I wanted to build a nitro short-course truck. Whew, it's been a long time since I wrote a Build Complete thread.
