    Paintwork looks fine to me.

    And you are only going to scratch it on the rocks!!

      Worked on getting the body near finished. I must say that I DO NOT like detail painting by hand. My O.C.D. goes off the chart with small imperfections. I guess sometimes we just need to let it go...

      I also wanted change the wheels and tires. The wheels will get used on another project, and I wanted to turn to trusty TSLs for my tires. The TSLs have CI Duece's Wild foams all around.

      Once I got the decals on, the detail painting somewhat done, and the wheels and tires mounted up, it actually looks pretty good.

        Ran this rig in Round #1 of our local comp series. I came away with 1st place in Class 2.

        Two 10-gate courses; full SORRCA rules.




        Saturday was the first run since the refresh of the body. I think the rig did well, despite the long wheel-base. This rig has always been a solid performer; I have just hesitated to comp with it due to the long wheelbase. I did incur at least one reverse penalty due to the wheelbase. I had to reverse and add a little extra juice to get over a rock and through the gate.

        I think the motor is the only thing that needs to change at this point. I'll change the TX/RX to Futaba. I may change a few scale details. But, the motor was the only real issue I had. The Axial sealed-can motor (which was supposed to be temporary but has been in this rig for a while) just didn't have enough power in a couple situations. I'm not sure it cost me any penalties, but it needs changed nonetheless. I need motor wired soldered on the new motor I have and then I can swap them out.

          What the heck was that? Yep, that was Round #2... I ended up in 4th place; no podium finish.

          This round had three 10-gate courses, and they were challenging, if I do say so myself (I helped SteveC6R set them up).

          Let's just say... not my best outing... but, I've had worse. Still, I was a few bubbles off center. However, I got to see some great driving.

          The one issue I had was very unexpected. On course 1, I notice the slipper would slip way too soon for my liking when the rig was in a slight bind. It got a touch worse as I progressed the course. I'd chalk up a couple of reverse penalties to just that issue. It was easily corrected after course 1 by simply tightening the slipper nut. I didn't notice it being an issue again. I'll add that to the list to check once I get to do a once-over.

          Steering seemed to be the buzzword of the day. I noticed at least one spot that my steering wasn't a sharp as it should be because of the 4-link set-up with the CMS. I may decide to go to a three link set-up. The one spot I noticed the steering was less than normal was with the right tire dropped in a crevasse and the rig needing to turn sharp left to line up for an approach to gate 7 on course 1. Not sure if I can blame that for any penalties, but I need to ponder on changing the set-up.

          Always be tuning. Right?

          I got zero photos of MEAN STREAK this round. (Kinda sad, really.)

            I found a photo that SteveC6R took just after the situation I mentioned in my previous post.




            The left gate marker is just in front of the rig. Progress/direction is right, through the gate, down the rock, and around to the flags in the background.

            The rig ended up rolling off the rock, taking a gate (or two) and incurring a roll-over penalty to get right side up.

              Several builds have proved to me that a CMS and 4 Link just don't work reliably.

              A 3 link with Panhard works every time, I highly recommend it.

                A 3-link set-up is what I've ran on all my other rigs (except one with the servo on the axle).

                This rig came to me with different axles that didn't have a 3-link truss option. I didn't have real issues with it before, but it wasn't used in comps either.

                I agree, it needs to be changed, especially now that it can be.

                  I got the 3-link and panhard bits installed last night. No major issues encountered.

                  One of the more annoying steps that had to take place is modifying the stock plastic shock tower/chassis brace. One "ear" had to be removed to allow for the VP panhard chassis mount to be installed.




                  That was a pain because I didn't want to disassemble the whole rig to get that one piece cut. I eventually cut it with side-snips while prying it for clearance with a screwdriver.

                  The parts that installed on the axle went on without issue. Provided hardware + blue thread locker = secured.











                  After everything was in place, I found the panhard bar touched the diff cover limiting full compression of the suspension.






                  I plan to do some adjusting tonight to hopefully get better clearance to allow full compression of the suspension - at least full articulation.

                  While I had the axle removed from the rig, I deceided to remove a c-hub screw that was stripped when I traded for these axles. A few minutes with the dremel and a flat screw driver took care of that problem. I replaced it with a fresh stainless piece and some blue thread lock. (It looks like it had red thread locker on it.)

                    I worked some on the panhard bar situation. I tried a couple of different way to position the panhard, but to no avail. It looks like it was designed to go on one way - with the bend point towards the rear. I understand this will work in most situations because the bend should clear the diff cover and 3-link, but I have the axle pushed forward more than a stock SCX-10.

                    No matter what I tried, the panhard bar would hit the frame, or the 3-link mount, or the diff cover, or all of the above. I resolved to using bump-stops on the front shocks. Not necessarily to prevent contact at full compression, but to eliminate contact on full articulation. The rear 4-link truss hits the chassis brace at full compression but there is no contact on full articulation. I wanted the front to be the same.

                    I started out with half of an Axial stock shock bump-stop which measured to about 5mm. I removed the shocks and installed the bump-stop.






                    After cycling the suspension several times, I determined that the right (passenger) side needed a little more bump-stop (*cowbell*). I notched the inner fender to allow the chassis-side panhard rod end to touch the chassis. I removed the shock and replaced the 5mm piece with a 7mm piece.




                    That piece didn't completely fix the situation. There is still contact at full compression, barely, but still enough to make a noise to let you know it's touching. It did allow full articulation without sounding off that the link touched the frame. You can see that there is still contact at full compression.






                    I know that the rig would perform fine without going through the bump-stop thing, but I like to keep things mechanically sound and my installs "clean". The addition of the bump-stops will limit articulation some, but I usually run them on my rigs because I feel too much flex can be a bad thing.

                    I need to adjust the length of the panhard bar to better center the front axle. That should easily be done with a few turns of the rod ends.

                    I usually do all these adjustments as I am building the rig, but this time happens to be a rig I didn't assemble. It's still fun & games.

                        Can you notch the frame and then braze in a notch to strengthen the frame in that section?

                          I could notch it, but I can't braze it (never have brazed).

                          Notching is a good idea, but may be more modification than I want to take on. Heck, I didn't remove the brace to cut it.

                          If I see that it hinders performance, I'll revisit the options.

                            I swept the cobwebs off MEAN STREAK last evening, and did a once-over in preparation for the comp this weekend. Everything looked fine and the hardware was tight. I removed the winch controller from plan B and installed it in this rig, along with the pull-pal. I tested everything to make sure it did what I wanted; all did fine.

                            I added a couple extra decals and called it a night.

                              [SIZE=3]Well, Round #3 was a tale of two courses... One good and one bad & ugly.

                              Gate 3 on course 1 was not my friend. It was a non-assuming gate that ate my lunch. It refused to let me through. After paying the toll - several winches, several reverses, and a gate penalty (IIRC), I finally was allowed to pass. That set the tone for the rest of the course. Then gate 9 finished me off. A line that has been ran so many times in years past, but this day, it took it's revenge. With mere seconds to go, MEAN STREAK lay on it's side, frustrated and embarrassed, I gave up. I was defeated. I did not finish course 1.

                              Course 2 was a different story. I managed to incur only six penalty points, but that was not enough to keep me out of last place for the event.

                              I could tell there was an improvement in steering consistency when off-camber from the installation of the 3-link set-up. I saw no real issues other than the poor driving on course 1. I need to get the butterflies out before starting somehow. I need a warm-up course.

                              I think I will change up the wheels and tires. I need to get the track width narrowed a touch. I've seen a few spots where the overall width of the rig hurt whether it was a gate hit, or having to use extra reverses.

                              Here is a photo of my friend, gate 3 on course 1;

                                Getting ready for Round #5...

                                I changed the wheels and tires in order to narrow the overall track width. I went with VP Method 101 with Pit Bull Mad Beast tires and Crawler Innovation foams - Lil' Novas in front & Deuce's Wild in the rear. Using .350 hubs with the XD centers narrowed the overall width from the previous set-up by about 1/2 an inch.




                                Not much else has changed other than some fresh bearings in the knuckles. I feel like there is too much slop in the front stub-shafts. Some of it was from the bearings, and some of it is actually slop in the knuckle bushings. The bushings are the upgraded VP brass bushings, but the holes in the knuckles seem enlarged a bit. I'll probably change the bushing down the road to see if some new ones tighten things up some.

                                I did a once-over and things are tight and lubed awaiting this weekend.
