SVEN's Trail Class Rubi

[SVEN]

Trail Class specs can be viewed HERE.

Won this SCX10 in the 2012 Christmas Giveaway (thanks RPP!). I've been beating on it in stock form for the past year and now it's time to give it some new life for the new USRCCA TRAIL CLASS.

I don't really intend to go all out buying stuff for this. The only thing I've purchased is a steering servo. Everything else is from parts accumulated over the last 10 years. It will be repping some RCC 10 Years stickers for sure.

Per Trail Class rules, either dig or 4 wheel steering is allowed. I will be using an Erickson dig unit, because I have one and I don't like the look of 4ws on a JK.

Power will be supplied by a 4 cell lipo, going to a Holmes Hobbies BRXL (won at Nats last year, Thanks John!). And then to a 55t Holmes Hobbies motor I had from the Clodbuster days. The motor looks to be in good shape and I am hoping the 4 cell will be enough to wake it up. We will have to wait and see on that.

Here it is before the teardown begins

To get the dig unit in, I had to rotate the skid 180*.

While I was getting into that, I found some Axial high clearance links to put in the rear. Upon installing the lower links I found that they would bind on the stock upper links, so I used some plastic high clearance links for the uppers as well (in the reversed direction).

The high clearance links add about 1/8" to the overall length. The rules allow for + or - 0.5" in the wheelbase, so the little bit of extra length shouldn't hurt anything.

Let's see what you can do with this, Grasshoppa!

Ive seen a Youtube video of a guy running a 55T on 3s, and the thing had torque for days, id say if i had to guess the speed was maybe 1/2-3/4 of what a stock rtr rubi does...so i was actually super surprised how quick it was, 4s should definitely still have good wheel speed

Drew up and cut out a rear electronics and dig servo plate on the old router. I havent cut anything in months, so it came out a little rough, but good enough to use.

ESC and rx are mounted, I just need to solder on a deans connector for the esc and find an extension for the steering servo wire. The mounting plate has holes for the stock rx box, if I want some added protection for the receiver.

The 4 cell 850mah packs I use for my Super fit nicely up front between the frame rails and is strapped to the crossmember.

Took it to an ETRC competition at the Ocoee Whitewater Center in Copperhill, TN. Had a blast running the Trail Class courses and also the 'for fun' 20 flag trail run.

First thing on the to do list is a battery mount for a full size pack. I killed two 850mah packs on the trail run and only made it half the distance. Still fun while the packs lasted though. Also need to make the front bumper less in the way and take the spare tire carrier off. I don't see any flats in my near future, so it's got to go.
