Hey Chris.
Good looking photos of the rig. Glad to see you finally posted up what you've done so far. It's come a long way from the huge mess it was when you bought it from the guy down the street.

I'm anxious to see pics of the shaved rovers.

I need to see if I can invert my shocks like that. Every little bit helps. There's just no room on that darn mini!

Hopefully I'll have my pile of parts back together soon and we can meet out at Sam Louis.

Thanks MrCrackhead. Ill be posting pictures of the shaved rovers after work today and also a little write up on how I plan to repair the one I shaved a little bit to much. I was excited that my 4.5 hours of rubber sculpting was about to be completed I quit being careful and messed the very last one up. I think I can repair it good enough to last until I get another set shipped to me. Oh and that pile of parts is going to be a BA rig when you are finished thumbsup on the work post up a build thread so other can appreciate all the fab thats gone into!

I recently switched from brushless to brushed I have a novak 55t rock star motor my spur gear is 93t and my pinion is 17t. This setup gets me decent wheel speed but when I tested it out on some steep decents I noticed my braking stinks and my rig will slowly roll down hill instead of holding. If I switch to a 15t pinion I have no wheel speed but awesome brakes. I've noticed a lot of people use an 87t spur and 14t pinion. Can someone please give me some insight on this all research I've done just seems to gLk about how fast and how hot the motor and esc get. Any help or point in the right direction would be much appreciated.

I run 14/87 because that's what both of my Scorpions came with stock. Recently I grabbed one of the 20 tooth pinions from the spare parts bags, and tried that out on the CUCV (1.9 t/w). It picked the speed up nicely, which would probably be good for trail running, but I didn't like the feel of how it crawled. Just felt too flat and powerless for me. When I start ordering parts for my next build, I may grab a 16 or 17 tooth pinion and see if I can get more speed than I have now and still have enough torque to feel nice and snappy.

Nice job on snagging that Helios body!

That locker is from RCP, made for quite a few years now.

A 35T Holmes motor should provide good wheelspeed and low speed crawling using 14/87 gearing. A 3S battery would be better to power it though.

Good looking rig with yet another body proline shouldn't have discontinued....

Tire Repair
This is the Rover I shaved a little bit to much

I started by grinding the little rings so my patch will lay flat.

Then I glued on this patch I got from Walmart is just a bicycle tube repair kit $1.99

I let it dry for about 30 minutes then removed the clear plastic cover and applied more glue around the edge of the patch

Make sure the patch is completely flat and let the extra glue dry(I waited an hour) before you flip the tire right side out

Ive tested this patch job for a couple of days now and it seems to be holding up just fine. I was going to buy a new tire and still will but after seeing how well the patch is holding ill wait till it fails before I switch it.

Nice job on fixing your "oops". It looks solid. I'm sure it will hold just fine.
Have you thought about shaving the patch a little to keep the softness uniform throughout the sidewall? Maybe you don't notice it....
Now you need to narrow your wheels to get some clearance back. Those tires all look flat!
Off to my brother's wedding. If I can get my junk put back together when I get back, I'll try to hook up with you at the park. I'd like to see the new tires in action.

Thanks dude! I haven't thought of shaving the patch that's an awesome idea. But honestly I haven't noticed it being a problem. Yesterday my novak 55t gave up so I soldered in a 55t tekin hd im hoping will fix my braking issues but I have to make a spacer for it. So after my coffee I'm off to the laboratory!

Awesome photo amigo. Gettysburg area rock is amazing. The dished shaped faces, car swallowing cracks, and staircase ledge systems are really fun.
I can't wait for my "new" AX10 to get here from my brother.
I absolutely love my MRC....but I want to span some of the sick gaps you drove that day...
However, I'm going to get my MRC to crawl up the "Ice Dihedral" before you make it....just to prove that (small) size does matter!

[chris.martell]

Brother that rock is insanely slick around devils den and also rather large. I think alot of the lines there are gonna go. Hurry your brother along and get that ax10 in your hands so we can go back and have some fun. As far as the ice dihedral goes theres no way you will send that before I do, I found it ill I have it's first accent!
