Jammin SCRT10
 

Recieved my Jammin SCRT10 kit today and it is sweet. I am glad I waited and got the Jammin over the Ofna and Traxxas 4x4 SC trucks. I have a CRT.5 and the Jammin shares many of the same parts. Aluminum shocks, cvd's in front, aluminum toe plates, full bearings, solid motor mount, nice rx box, plastic shock towers, nice body and esc tray. Only minus so far I have noticed is that the stock battery tray can only fit a 2s lipo.

More Pictures
 

More info, wide plastic 46T spur, comes with a 13T Mod 1 pinion and a bore reducer for those that want to run smaller motors with an 1/8 shaft.
A few more pictures.

Update
 

Started working on putting the kit together. Added a Mamba Max and Neu 1509/2D motor. Good news is most of the parts are the same as the CRT.5 so I am moving over a bunch of cnc parts (steering rack, spindles, c-hubs, wheel hex, etc). This also means replacement parts will be easy to get since the CRT.5 has been out for a while. Bad news (at least for me) is that the Battery will only hold a 2s lipo pack. I guess this is ok if you will be running a smaller brushless motor and 2s, but I want to use my Neu 1509 on 3s. I was running the Neu and 3s in my modded CRT.5 and it was a rocket and ran very cool, so I moved my custom carbon fiber battery tray over to the SCRT10 so I could use a 2s or 3s battery.

Here is a Protek 2s and a Losi 3s all 5000mah. Only the 2s will fit in the stock tray. My Reedy 2s hardcase also fits in the stock tray.

Yeah I can't wait to get out on the track. My CRT.5 was one of my favorite trucks, so the longer SCRT10 should be sweet.

Looks good, didnt expect it to come with the pinion and bore reducer, nice features :)

Cant tell But are the suspension components- Aside from the shock towers- the same as the crt.5

Is the chassis plate from the original nitro CRT.5?

How much longer is the chassis than your crt.5

stock crt.5 has a wheelbase of 8.8in
Scrt is 12.75in

I'm thinking of picking up that plastic spur for my CRT.5 to lighten things up a bit.

What would it take to convert a .5 to a SCRT? Looks like mostly a longer chassis and a the bumper/body mounts. I like some of the hardware a bit better on the .5 (towers, CD mount mostly, does it have plastic knuckles?) but looks GTG.

How long is Mike's .5 chassis?

They seem to be exactly the same as what is on the CRT.5 pro. aluminum shock bodies, screw type adjusters, alloy/plastic shock cap.

It looks like a stretched CRT.5 chassis. Has the mounting holes in the chassis for the nitro parts (not used).

Update
 

Finished the body, just a super fast rattle can job, I normally use faskolor but that paint takes weeks to cure and I wanted the body dry so I could get it out on the track tomorrow. I installed the battery tray, motor, esc and tested it on the work bench. One thing I did notice was the stock tires are pretty hard (compound) and much smaller than what others are running. See the picture where I compare the stockers to some Pro-line bow ties for an Associated SC10.

Stock tires and pro-line bow ties (Associated sc10) the Bow tires look wider than normal because there not mounted, but you can see how much taller (larger diameter) they are.

So is this SCRT10 the clone version?NH has 2 listed forsale/backorder.

Looks awesome, great job

wow, what a beauty, I like!! And a massive motor!
you should try to put the esc on the steering servo, that lowers the cog, and U get a bit more steering and you avoid wheelies.

Clone version??? I ordered my truck from NH.

On the Track
 

Got my truck on the track today and I was very impressed. It handled and felt more like a smaller/lighter 1/8 scale buggy. My truck was probably over powered, but I am used to it (ran the same setup in my CRT.5) and was able to control it. There were several new Slash 4x4's, 1/8 buggy/truggies and regular SC trucks on the track (open practice). The Slash 4x4 was pretty nice and it was close in speed/handling to the Jammin. The best thing was being able to hang with the 1/8 buggy/truggies. Until one took exception and blasted me in one of the high speed sweepers and took out my rear bumper. Pro Chad Bradley was at the track the day before running his Jammin SCRT10 and was just smoking everyone. I had so much fun with my Jammin my SC10 never left the car and my 1/8's barely got used.

Wheels/tires Update
 

The stock wheels/tires actually worked pretty well on the blue groove track I run on. But it was bugging me that I couldn't use the Slash proline wheels/tires (I have several new sets). So I was sitting there and I remembered that on my CRT.5 I ran Associated truck wheels by removing the 12mm hex and just using the pin. "Light Blub" well I have some old Proline Bead Loc's off my SC10 sitting right there so I pulled off the hexes and the installed the SC10 wheels. They actually fit pretty good, and cleared the body (at least in the track). I am not sure how they will clear in the up/down range when the suspension bottoms out since they are bigger in diameter. The larger size may also require regearing and will effect the handling (higher CG, more mass, etc.) but I will try to get out on the track this weekend and run some tests.

Parts, need to add a few spacers, otherwise when you tighten the wheel it will bind on the carrier.

Bumper
 

As I mentioned in an earlier post the first day out on the track I had a little accident and broke the front upper bumper support. It's been kinda slow at work this week so I figured while I was waiting for a replacement I could see if I could throw something together using some spares I had laying around. I had previously used a Slash front bumper on my 1/8 buggy SC conversion, it is pretty easy to adapt to other trucks, it is pretty tough and I had an extra one. So I took some scrap aluminum I had left over from some skids I made and put together a new front bumper for my Jammin using the Slash bumper. As a bonus I got a front skid plate as well. It took me a hour or so to make the parts and it bolted on without issue. The Slash bumper is very solid and has a built in shock absorber, unfortunetly it sits about 1/2 too high in relation to the body, oh well.

Here are the parts required, Slash bumper and some 6061 aluminum scrap.

Here it is with the body on.

Dang that is a sweet looking rig! If I picked up a short course truck, this would be it! I bet the 1509 is a screamer.


How much room do you have on the chassis for the battery? I am wondering if a 6s 2500mah system pack could lower the CG.

If I remember correctly the stock Batt tray interior dimensions are 6"x1"x2". My custom tray is a little more open and allows for a larger battery all the way around. Where you have an issue is if you go too wide you run up onto the mudguard mounting bumps. You are right about the low mah 6s it would probably be smaller/lower. But I have a bunch of 3s I recovered from my dead 4 and 5s 5000mah Zippy's.

Size
 

Well I don't own a Slash but I do have an SC10 so here they are for a size comparison.

Big Shocks
 

I have been slowly moving optional/modified parts from my CRT.5 over to my new SCTRC10. Today I added the jato front shocks and 1/8 buggy rear shocks. First there is nothing wrong with the stock shocks, I just run big bore shocks on my 1/8's and I like the feel and consistency they provide, the larger shafts will make the suspension more rigid and reduce shaft bending. Also, I ran this setup on my CRT.5 and it was dialed. I am still waiting for my replacement front bumper so I still have the modified Slash bumper installed. I had to modify the Slash bumper to allow clearance for the larger shocks. So I made a new top brace and cut some of the plastic from the Slash bumper.

Rear shocks

Nice... Z-Car buggy front shocks!

Looks like your truck is moving along well. Are you still out at Revelation?

Yup Z-Car buggy shocks (piston valve, Progressive spring, big bore). Home track is Hot Rod Hobbies in Saugus, SoCal.

Which truck handles better...Jammin or Associated? Just curious. I actually like the look of the taller front bumper better than stock.

If Mike got a hold of one of these and made a similar chassis, it would give people the choice of 2 chassis for the Jammin line. Would probably sell very well as so many people have the crt.5 and the parts are the same as the new truck

I agree 100%, the stock chassis is pretty tame, no cutouts in the chassis for weight reduction, still has holes for the nitro stuff, etc.

Jammin and Slash 4x4
 

Ok, earlier I posted some size comparison pictures of my Jammin and Associated SC10. I got my hands on a Slash PE 4x4 and here are some shots comparing them. The Jammin has a much lower CG, and small wheels/tires. I have already had the Jammin out on the track and it is a fast, sweet handling truck. I hope to get both out on the track this weekend, curious to see how the higher CG and bigger tires effect the Slash's handling.

CG - With the suspension arms close to parallel the Jammin sits much lower.

do you by any chance go to west coast rc? I'd like to see that truck run looks sweet

That's a little bit of a drive for me, so for now I run at Hot Rods.

Update
 

Ok, I was able to get out on the track this weekend (no racing, open practice) and test the Jammin SCTRC10 vs the Slash 4x4. There was also an Ofna Hyper SC out on the track as well. The Traxxas is a great truck and a lot of fun but for me the Jammin is a better racer (on the track). It handles a little better, is easier to drive fast, etc. One thing about the Traxxas truck if you race you need the center diff, it is night and day regarding the handling with the diff installed. The Ofna truck is very nice as well and between the two (Jammin/Ofna) they were pretty evenly matched. I saw no advantage with either truck when I was out on the track with the Ofna truck. These things are a blast, my poor 1/8's pretty much sat on the table.

cool pics I sometimes go to hot rod maybe I'll catch you out there one of these days

Could you tell me what the actual tire diameter mounted to the wheel is? Wanting to figure out speed and gearing with the speed calculator.

Thank you.

I think the outer diameter is 3.9".
