A few months ago I decided to build myself a truck to the Sorrca class 3 rules, hoping to do some comps with it (which still hasn't happened...soon hopefully though). Rather than go full on 2.2 sized everything I built it using 1.9 sized components.
Enduro axles (two steering axles) - Beeftubes c-hubs and SSD brass knuckles up front, SSD aluminum c-hubs in the rear. Other than that the parts are standard Enduro. I did do various mods to get as much steering angle as possible, and I'm fairly happy with that. I've found however that these axles have two disadvantages...one is lack of aftermarket support (I wanted an OD or UD ring and pinion but nobody makes them. The other is they aren't a high pinion design, and as a result the rear driveshaft and cvd at the axle take a beating and end up being a point to get hung up on.
Chassis rails are the Gspeed V3 in fiberglass. Designed for SCX10.2, they work well for a lot of different applications. The rails are all as they came other than cutting a little off the front of the rails to pull the front bumper in more. The dual servo mount up front is by Team Garage Hack and bolts right up to the Gspeed rails, its very nice. My only complaint is that I wish that it mounted a little further forward. I may end up doing some drilling at some point or making a different mount.
Links are standard Enduro up front, long wheelbase Enduro in the rear. I'm using a mix of Enduro and Traxxas rod ends to get the lengths I want. Three link front, four link rear. For the frame side panhard mount I'm using the Gspeed G-MP multi platform mount which allows for some adaptability to different setups...pretty nice.
Shocks are Enduro kit shocks. I run mini t front springs using lower perches that I designed and printed. Still experimenting with oil but I'm running substantially heavier than the kit oil weight.
For power transmission I'm using the Team Garage Hack forward motor mount and transfer case. This serves a few purposes. It sheds a little weight from the standard Enduro trans, it moves weight forward, and it gets some Sorrca scale points. I'm using the version with 15% OD built in. At first I really wanted more OD (hence my disappointment in no axle gear options) but it's actually working pretty well with the 15%. The motor mount bolts onto the Gspeed rails using included adapter plates, and the transfer case bolts right onto the included delrin skid plate.
Electronics are pretty basic...not cheap but not too expensive. Savox 1230sg servos front and rear. Reef's 422HD servo winch. Mamba micro X ESC running a Holmes Hobbies Crawlmaster Expert 16t. Right now I'm using a Castle 10 amp BEC, which I think is ok with the servos I'm running. A 650mah 3s battery mounts on the right electronics tray. The trays are designed and printed to fit exactly to my truck/body.
Wheels and tires vary, but I set the truck up around the Pitbull 2.2 Braven Berserkers. I ended up with those on VP 2.2 wheels and CI foams are inside the tires. I also run 1.9 tires/wheels along with 1.9 tires stretched onto 2.2 wheels. I'm kinda torn right now, but I think the best overall setup is Proline 1.9 Krawler KX that I have on some chanquish 2.2 narrow wheels. But the VP wheels with the Berserkers just look awesome (that's what's in the pics below).
The body is a Tamiya F350 that I've done some work to. Pinched the front, trimmed for tire clearance, etc. The bed consists of just the bedsides bolted onto a tube bed. Running a Bomber interior which is too large in proportion to the body, but it fits with trimming and looks 'good enough' while serving its purpose.
Metal work includes a custom front bumper with stinger, tube bed with roll bar and integrated rear bumper. The bed is designed with an extreme dovetail for tire clearance. Got a few scale goodies back there in the bed like an Optima battery, tow strap, milk crate with oil bottles, etc. I printed a radiator and mounted in the back to hide the rear steering servo when viewed from above.
Anyway, this has been a fun build and a learning experience for sure...can't wait for the next build so I can apply some of the things I'm learning in this segment of the r/c hobby. I also can't wait to get to a comp with this thing, I think I might wear it out before that if I don't get to one soon. It's so fun to drive with the rear steering which adds a lot of capability too.
