Short story long this is the MRC pro roller I won previously this year. MNRCRC had a $10 challenge where we all competed with this truck. Thanks to Nicklepimp and Big Baller for making it RTR for the event. The seasons about rapped up here in northern Minnesota but this will be my 2012 comp rig. Enjoy!

The list begins with what I have to date.

Mini juice chassis
Stainless links with traxxas ends
VP little harry w SS weights
Crawler Innovations foams memory/med
Hot bodies red dot rovers
Traxxas rod ends
RC bros high steer knuckles

RC bros servo/link mount
RPM servo posts
BDW motor plate
Losi aluminum 12mm hexes
Jeepindoug C cups

First thing I ripped the entire truck down and went through it. I've just seen too many mistakes on pre built rollers. Everything was good though IMO. I greased the tranny and rear end with VP's grease. I also glued and sanded all the edges of the carbon fiber to prevent it from separating.

I purchased the chassis and links from ol' gravy leg just last weekend. I also purchased the rims, tires, foams and hardware from him. Im really happy with the deals I got. I also removed the front memory foams and replaced them with the softs. The temps in Minnesota seem to make memory foams hard.

I went through and replaced all the rod ends with traxxas 2742x they are a little shorter and the shaft area is round instead of square.
I then had to shim the rear links to compensate for the shorter link ends. The links in the rear are longer for more front bias and to push the wheelbase to 8.5" I just added some washers til I get my wheelbase and axle clocking set. This will be adjusted later after everything is in place.

wild bill · 09-25-2011, 12:25 AM

I put some time into the front end. For now its assembled with no grease or internals for mock up. I did the clocking mod to the axle and im waiting for the Traxxas mini revo pinion for the overdrive mod. The pic shows the clocking I did. I also did some cutting to the top of the housing so the steering link would travel more to get the max steering angle.

wild bill · 09-25-2011, 12:33 AM

Im kind of stuck now. Im waiting on my servo/link mount and posts I ordered today. Im also waiting on the traxxas pinion and some mini t springs.

I did go through the shocks. I filled them with 40wt for now til I can get a feel of it. I also am going to limit the front shocks a bit more internally. Currently it has the stock pro roller shims in the shocks. I like to run softer springs with alot of droop. I like to set the ride height with spring rate. I like it to settle a good 1/2" at ride height. Ill run the back of the skid at 2.25" with it 2.75" at full droop.

Once my servo plate arrives im going to shorten up the front uppers since they will be mounted behind the servo due to my steering link.

wild bill · 09-25-2011, 12:45 AM

Here's a couple more pics of the steering. I can safely dermal more from the axle housings to get more travel but the cvd's are just starting to click now. I like it to bottom out a bit if my end points aren't perfect.

Now I patiently wait for more parts to arrive. Its about all I can do for now.

Looks good Bill, can't wait to see it perform!

Thanks! Ya I can't wait to wheel it. It wont be done for finals next week. Cross my fingers but Kwapi is talking about building a 1.9 coarse in his garage this winter.

wild bill · 09-25-2011, 11:41 AM

Just playing around with the weights. I like to run with the 60/40 bias. Obviously there's no servo plate, servo and electronics but my projected layout will be pretty balanced. I plan on running between a 350-500 mah 3s lipo. I plan on putting the FXR and bec on the rear uppers. Rec will be taped to the back side of the tranny. Battery will be placed on the front uppers. Battery will be determined on how much room I have on the front upper links once I get my link mount.

For now I have four weights up front per wheel and two in back per wheel. I have a feeling this is what ill run.

wild bill · 09-25-2011, 12:08 PM

Here's a little piece of history. We had a $10 challange which consisted of 20 gates in 8 min. I amazingly finished the coarse with a flawless victory. MNRCRC purchased the roller from Jerry's RC. Baller supplied electronics and Pimp put it all together. Here's some pics.

wild bill · 09-25-2011, 12:38 PM

Well im still doing some tweaking. I had to shorten the front drive shaft a bit. Roughly took about 3/8" off both ends of the shaft with a dremel.

I like to pay close attention that the suspension cycles freely with no binding. The shaft was binding when compressing the suspension.

wild bill · 09-25-2011, 06:55 PM

Well I purchased a couple more items this evening. Thanks to motorman1600 for the new FXR and inkdaddy66 for the SR3500. Im thinking about possible making a mount off the rear axle to mount the esc between the rear upper links. Will see what I come up with.

djjiz · 09-26-2011, 10:20 AM

Enjoy.. The best man won.

irok22s · 09-26-2011, 07:04 PM

Looking good bill. You should do a comparison shot with the cf chassis and the delrin chassis. Sense you do have my rig in your possession at the moment. Id like to see a side by side of the 2.

Ha ha. I gave you the truck afterwards fair and square. Not my fault you gave it back.

Too late.... trucks already torn down. Ill post pics.

wild bill · 09-26-2011, 07:13 PM

Irok22's and my mini.

wild bill · 09-26-2011, 07:30 PM

Well I tore the wheels and tires down. Im gonna get the wheels drilled at work tomorrow for venting. I live in the land of 10,000 lakes so its not unlikely to have water on coarse. I prefer to vent the rims vs the tires.

I also got the bit from Irok22's to drill the new holes on the caster mod. Ill post more detailed pics since I actually got a pm today on the mater.

I've decided im not going to run a bec on the servo. I normally make a y harness so the bec directly feeds the servo. Im thinking I shouldn't need to with close to 200oz fed by the fxr.

wild bill · 09-26-2011, 07:59 PM

Here's better pics of the new clocked C's and the the notch I cut for the RC bros steering link to clear after the caster mod.

wild bill · 09-26-2011, 08:00 PM

irok22s · 09-26-2011, 08:47 PM

did you get the drill bit figured out finally?
