TedBull's Titanium Bodyless MRC

[TedBull]

I have made some changes since I first built this rig over a year ago. Most significant change is a new Titanium chassis and Titanium bodyless cab along with servo/battery mount from (IRC) Infectious RC. I was in the right place at the right time to score their new setup.

Here is my list of specs: Some old, Some new.

*MRC PRO kit roller.

*JR DS 8711 servo. Its been great, no issues. W/ Racers edge horn.

*Losi zero ackerman aluminum hubs and knuckles clearanced for more throw.

*C-hubs rotated back for more castor.

*stock steering link and chunk of AX10 aluminum link for draglink.

*IRC Aluminum servo mount with integrated battery mount. Works Great.

*IRC Titanium chassis plates. (direct fit with OEM pro chassis).

*IRC Titanium Bodyless cab for IRC chassis plates or stock carbon chassis.

*Traxxas overdrive mod in front.

*Crawler mafia underdrive mod rear.

*Case halves are thru bolted.

*CC Bec at 6V for servo.

*MaxAmps 2S 860 mah lipo's.

*Spektrum SR3500 micro RX.

*MIP driveshafts.

*Aluminum HR tranny gears.

*Tekin FXR esc.

*Vanquish Products little harrys.

*Stock rovers with nova foams.

*Losi shock outboard kit, stock shocks inverted, internally limited a bit.

stock springs.

*Crawler Mafia motor.

*BWD billet motorplate.

This rig has performed well, it is a tuff truck. All the brearings and CVD's are original and have seen many comps in the last year but are holding up well. I had to replace the underdrive pinion once from normal wear, and I had to replace the front ring gear from overdrive pinion wear. I am very happy with it. I realy like my new setup with the Infectious RC Ti chassis, Ti topper, and servo/battery mount. It is a clean setup that works.

That looks great. I ordered mine and can't wait to build it up.

Did you make your own underdrive mod for the replacement in the rear or did you go with a rockhard one again?

[TedBull]

When I had Paul aka "rock hard" mod my rear case I bought two pinions from him. Getting the mesh right is key. I need to get another one for a back up. First one got me thru most of last season.


Todd (rockslyder) from our club has had good luck with a couple pinions he modded himself.

Damn, that looks good! I am waiting on IRC to release those cabs and then I plan to purchase his kit for my kid's Pro.

Keep your eyes open Jeremy, should only be a couple weeks when you see the cab and servo mount posted for sale!

Looks great Ted, good job on the panels too!

[TedBull]

Thanks JB. Glad you and Brian got me setup becuase I love it. The servo mount/battery plate is genius, works so well and it keeps the stock links and just bolts right on. Awesome.

And the Titanium speeks for itself.

I love the rear split window, nice work

The under drive mod uses a lower tooth count rear pinion so the rear axle is slower than the front axle. Combined with the Revo overdrive front axle mod sorta gives you a "dig" effect.

As to the case halves, remove the screws that hold the axle case together near the diff, make the holes go all the way through the rear case 1/2, install longer screws with a nut on the back side. This prevents stripping out the case screws which:
1-makes the case stronger
2-keeps a better pinion/ring gear mesh

The underdrive mod is a custom mod. Paul, aka "Rock Hard", aka Crawler Mafia modded my rear axle case and built my underdrive pinions. It requires some fabrication work and no one sells a drop in pinion.

To rotate the knuckles back you need to shave the corners off the axle tubes so you can rotate the hubs back. Then make new holes for the mounting screws, very quick and simple.

Its all been covered in length in multiple threads you just got to search it out.

and as far as the knuckles being rotated. how far should i go?

thanks

Take your knuckles and C-hubs off the front axle. Shave down the corners on the axle housing, top front and lower rear corners. Shave and fit, shave and fit untill the c-hubs can rotate back. Put everything back on and rotate both c-hubs back untill the steering link can go as far back as possible with still having clearance when fully turned. Then mark and make your holes for your mounting screws. It realy is very simple, I used a angle grinder and body reaming tool.
