Another recruit to the Blackjack Army I just finished up the latest rebuild of my crawler. After hacking my stock AX10 chassis to the point there is nothing left to hack, I decided it was time for a new chassis. I was going to make my own, but I came across a great deal on a new Blackjack in the classifieds, so I jumped on it. The new specs... Blackjack Chassis Axial axles CKRC Heavy Duty Lockers R2 disconnect Crawlmaster Quark 33 Castle BEC Traxxas driveline Traxxas #3760 shocks Losi Rock Claws with Kreepy Krawler foams JR XR3i 7-cell split pack from cheapbatterypacks.com I also have a set of Teflon bushings for the R2 from Rocksmith that I need to install It is a belly dragger at 2.25", I may have to raise it a little, I need to do some testing first. The top of the chassis sits below the top of the tires which I love. This thing is insanely stabile since the COG is so low. http://img.photobucket.com/albums/v1...3/P1050061.jpg http://img.photobucket.com/albums/v1...3/P1050065.jpg http://img.photobucket.com/albums/v1...3/P1050066.jpg http://img.photobucket.com/albums/v1...3/P1050067.jpg I originally wanted to run a puller, so I mounted the transmission up quite a ways to make room. After looking at the chassis for a few days, I decided I wanted to run a compact brushless setup and order up a Crawlmaster and a Quark 33. All wired up and ready to go: http://img.photobucket.com/albums/v1...3/P1050068.jpg http://img.photobucket.com/albums/v1...3/P1050070.jpg http://img.photobucket.com/albums/v1...3/P1050072.jpg The wheel speed is not very impressive with the stock 8t pinion that came with the R2, but the low speed control is amazing! The Quark is such a smooth controller. I put in a 10t pinion and the wheel speed improved dramatically, but I lost some of that low speed control. It is a temporary solution, I will be volting up as soon as the budget allows, I’m thinking of stepping up from 7 cells to 9 or 10 (and then go back down to the 8t pinion), should definitely help get my wheel speed up. :twisted: I will be making a trip to the hobby shop on Friday to try to find a body that will fit it, I want to find something that I can slam down as far as I can on the chassis, so I will post some pics when I find one.

That is a nice loking BJ. I like the covering on the wires, it makes it really clean looking. Do you have any shots of your R2D shift linkage, I just like to see how everyone does their linkage differently. I guess you can see it in the top pic. How doe it work, do you get any binding. |
awesome, i love your wiring, where did you get that stuff? |
I'm interested to hear how this works for you. I've been curious about having a low truck like that and have been conflicted about how it would work in Washington. |

Very nice! "thumbsup" I love my BlackJack even though I am running a sprung setup. I have about 3 1/2" under the skid but it works well where I crawl. And for it to be that high up, its still very stable. I have not done much tuning with it yet but I took 2nd at its first comp so it may not need it. :-P |
looks really good man, i like it alot. im thinking about getting that chassis |
nice welcome to the bj army! mount the body low! this rig is awsome!!! run either a grappler or a bug body you can slam them |
Looks good...Welcome to the blackjack army"thumbsup""thumbsup" |
Welcome! Those sleeves look sooo damn nice. |

Here is how it use to sit with that setup: http://i19.photobucket.com/albums/b1...0/P1040869.jpg |
Not to hijack your thread or anything .. but what weight of oil were you using? I tried the Integy shocks, with 3 hole piston front, 2 hole rear, 1000wt rear, 900wt front...worked pretty decent. I was thinking of using the longer rod ends, but did not feel like taking the shocks back off when I had the idea...I just wanted to try it, I liked it overall. But a new chassis is sounding way cooler... :) |
I was using 100wt with the 1 hole piston in the front, 80wt with 1 hole in the rear. It worked well, but it could be a little floppy at times, it needed thicker oil, but I was too lazy to change it. :-P |
Got my new body on, an HPI Silverado. Did my first attempt at a fancy paint job, put a couple stripes up the body, turned out looking pretty good, there are a few crappy spots, but it was much better than I expected. Now for some pics: http://i19.photobucket.com/albums/b1...8/P1050080.jpg http://i19.photobucket.com/albums/b1...8/P1050081.jpg http://i19.photobucket.com/albums/b1...8/P1050088.jpg http://i19.photobucket.com/albums/b1...8/P1050089.jpg http://i19.photobucket.com/albums/b1...8/P1050091.jpg |
Looks good. now get back in line private |
Looks great. I am doing a rebuild on mine. |
Took it to it's first comp today with a total of 20 minutes of drive time on it, came home with 3rd place, highest I have ever placed. "thumbsup" Had a little breakage so I had to take a penalty to fix it, had I not got that penalty I would have been in 1st. :-( I can say 100% without a doubt that I would have been no where near the top of the pack with my old setup. Had a little difficulty with my front axle, the ears of the inner C's and the link mounts kind of ripped off. :-P http://i19.photobucket.com/albums/b1...Breakage02.jpg http://i19.photobucket.com/albums/b1...Breakage01.jpg I was able to borrow a knuckle and zip tie the links to the axle and finish the course though. 8) http://i19.photobucket.com/albums/b1...Breakage03.jpg |
damn thats some breakage!! glad youre liking it! |
