Smile Peanut The Destroyer....an SW2ber rock racer

After competing at the HPI/rccrawler Nationals in September I shelved this rig to run a different chassis for competition crawling. Ever since, I've been trying to figure out what to do with Peanut since he is one of my favorite rigs ever. Last week an announcement came up for a rock race event and suddenly I knew exactly what to do with Peanut.

The chassis is a Bender Customs SW2 that I build a custom tube body for. I love the look of a tuber but I really liked the precision and adjustability that a machined plate chassis offers. So I combined the two ideas.

Here are some specs so far:
-Chassis: Bender Customs SW2
-Body: Custom tube
-Front axle: TLT, CVD shafts from RCP Crawlers, aluminum axle ends, TCS Crawlers aluminum knuckles, Hitec 5995TG steering servo, Heydco 1/2" wideners
-Front suspension: Triangulated upper links, custom link/servo mount, Hot Bodies Maxx shocks
-Rear axle: TLT, CVD shafts from RCP Crawlers, Hitec 645MG steering servo
-Rear suspension: Triangulated lower links, GC-1 link/servo mount, Hot Bodies Maxx shocks
-Driveshafts: Traxxas T/E Maxx halfshafts
-Tranny: Traxxas Stampede
-Motor: Holmes Hobbies Revolver Black (1000kv)
-Pinion/Spur: 22/84
-Batteries: Thunderpower 1320mAh LiPo
-Electronics: Mamba 25 ESC, MPI adjustable voltage regulator
-Wheels: Createacrawler 2.2 Slot Mags
-Tires: Imex 2.2 Red Rocks
-Wheelbase: 13.75"
-Width: Front 11.5"

This thing is pretty dang fast!!
Acceleration is great, the left rear squats a little and it lifts the right front about 2" but then it gets it's boogie on. It pulls some really nice tornado's on the linoleum floor thatks to the rear steer. This is going to be sooooo fun.

With a 20 tooth pinion acceleration was unreal but top speed was not quite what I was looking for. It's fast but not fast enough.
I swapped in a 22 tooth pinion and that seemed to be pretty good. It's prolly a little slower than the Stampede with the 12T Stinger. I think I may call that good for two reasons. One, the courses are only 24" wide and this speed seems to be at about the limit of what I can control going around corners. With the rear steer this things a handful for sure. Two, as it goes by you can smell the Mamba25, so that's prolly all it can handle.
The Mamba25 is starting up just fine with the 22/84 gearing. It gets damn hot if I crawl it for very long but once I lay into the throttle it cools back down. "thumbsup"
I've got a different motor coming next week to try out with a Mamba Maxx ESC so we'll see how that works out.

Willy is going to drive for me and he requested a bottle of nitrous and a fire extinguisher. I think he's worried about the Mamba 25 melting down!

You just gotta love the look of those Slot Mag wheels. Nice job Troy! They didn't quite have the right scale look for Guido but on this rig I think they look stellar.

what's going on with the inner wheels/hub area? some strange wideners, or reduction hubs???

The front end has wideners on it. The other thing you see are the steel washers that fit over the ends of the steering knuckles. I like to use washers because they add weight but can be removed to tune it if needed, they add weight to the axles without adding weight to the wheels (quicker acceleration), and they make a nice "tink, tink, tink" sound for cowbell effect.

I've run Red Rocks for a while a on a couple different rigs. They are a decent tire, I had them on a Clod based rig that I competed with in the Super class and usually finished in the top 10 out of 25-30 guys. They don't grip as well as a Losi or Proline tire but they do pretty good. Much better than the All-T's.
I put them on the racer because the extra diff clearance will allow me to blast over rocks easier, and the longer wheelbase will allow me to climb vertical stuff easier. In rock racing there is less emphasis on technical crawling over the rocks so I think the traction of the Red Rocks will be "good enough". In mud and dirt the Red Rocks work very well but not so much on wet rocks. That's where momentum comes in.

Thanks for the interest guys.

yeah i was just wondering cuz i run them and a lot of people tell me to get new tires but it wont happen cuz i like the axle clearance.
of course i might try the rc4wd rock crushers.

I have a set of the 2.2 RockStompers, the RS doesn't flex as well as the Red Rocks but the traction feels very similar.
When I drag a tire on the tile floor they both seem to grab about the same and they both make that "howl".

Thanks. The Red Rocks work decent. I have them jam packed with foams from an HPI Savage tire. That combined with the 1" wide CAC wheels has really helped with lateral stability. I have some "tire juice" that helps them stick on the rocks a little better as well.

Overall, I love Red Rocks as a good all around tire on a rig that needs a slightly bigger tire. They don't master the rocks but they do very well and they rock in mud, dirt, and snow.

Here's some video with Peanut doing what he does best.
