Scale Trophy Truck Build Hello RCCrawler, this is my first post here. I'll give you a little bit about myself and the background of this project and then I'll get into the build of the truck. I have been a trophy truck fan since roughly 1993 or 1994 when I got Ivan Stewart's Super Offroad, the Baja. It's a great game and I still have and play it 20+ years later. There is even an android ap for it. Super Off Road: The Baja - Super NES - IGN I was just a young kid at that time and loved the idea of trucks that can travel fast over such challenging terrain. Fast forward 15 or so years...There is a new Baja game that I currently spend plenty of time with; Baja edge of control Baja: Edge of Control - PlayStation 3 - IGN Finally just a couple years ago I came across Dust to Glory on Netflix. Dust to Glory (2005) - IMDb I have had various RC trucks in the past (4wd slash, Losi 5T, SCX10, etc) but wanted something different. I found the ideal RC trophy truck blog, downloaded some free drafting software and got started. Trophy Truck Slash Project Part 4: Chassis | Ideal RC After a couple weeks of planning and playing, I ended up here http://i37.photobucket.com/albums/e9...ps748c4a01.jpg I was reasonably happy with it until I scored a Brushlless Slash 2wd with the RC4wd cage on ebay for just a couple hundred bucks. Now, The RC4wd cage did not fit on what I had built, it was over 1" wider than my steel base plate and the rear suspenstion structure interfered with the cage. I shelved the original build and started over with a new steel baseplate. The cage won't work without modification becuase it is meant to work with a stock traxxas chassis, it's not tall enough to work with my design, so I had to add 1" to the bottom of the cage to lift it up into the body. I bought a mpa gas torch and some tubing and taught myself to braze yesterday Shameless plug for a good book. http://i37.photobucket.com/albums/e9...ps7180a645.jpg I am trying to figure out what amount of anti-squat to design into the rear suspension by moving around the rear link mounting ponts. Thus far I have the RC4WD Steel 2.2 wheels and their Dune TAs, and Integy Wraith rear axle and some HR Twin Hammers rear lower links. http://i37.photobucket.com/albums/e9...pseda726e8.jpg The donor truck came with a brand new but butchered Welchel body. It's not my first choice but it's un-used and I fixed it up with a little trmming last night. Hard to pass up on a $60 body when it's already in the box. http://i37.photobucket.com/albums/e9...ps0550ccf7.jpg My future plans include a rear rack to hold the 2 Dune TAs, and recovery tools. I will finish up the roll cage, add a fuel cell, radiator with fans and fab rear suspension mounts for the RC4WD King shocks and their ultimate scale shocks I am using for bypass shocks. This truck will have front and rear lights and as many other details as I can add such as side exit exhaust, fuel filler, window nets, etc. I was first inspired by Topolino's build when I saw it on youtube. His work is amazing and his camera and video work are some of the best. I don't know if it's tasteless or a rip off to post his video here but it is pretty amazing stuff. RC Desert Trophy Truck -RC4WD/Topolino Ultimate Hardcore Slash - YouTube I want to build a scale truck that I can beat on. To give my mind a place to wander, I got myself a new desktop back ground for my work PC Mmmmm Camburg.... http://i37.photobucket.com/albums/e9...ps9f41fe76.jpg |
Re: Scale Trophy Truck Build I spent some time this weekend and built a tire rack and rear bumper. http://i37.photobucket.com/albums/e9...psec840845.jpg http://i37.photobucket.com/albums/e9...ps931a3788.jpg I have my new baseplate almost finished. I need to snap some pics of it. |
Re: Scale Trophy Truck Build subscribe, looks good so far. Keep up the good work |
Re: Scale Trophy Truck Build I made some progress this afternoon. Rear cage is almost done, need to figure out a shock mount. Fuel cell support is in. I didn't take the time to buff the burned paint off of the tubing. I really like the EXO rear light and radiator. I painted the cap blue, too bad you can't tell. http://i37.photobucket.com/albums/e9...ps1f133bea.jpg http://i37.photobucket.com/albums/e9...ps255b1585.jpg http://i37.photobucket.com/albums/e9...ps5a30169f.jpg http://i37.photobucket.com/albums/e9...ps82b366ed.jpg |
Re: Scale Trophy Truck Build Very cool! |
Re: Scale Trophy Truck Build My honcho front bumper donated some metal to the shock mounts. I think they look pretty darn close. I'll back them up with a 5/16" tube and bolt though the plate and the tube for the shocks. http://i37.photobucket.com/albums/e9...ps8081c0bd.jpg DROOP CHECK! http://i37.photobucket.com/albums/e9...ps5b6ef272.jpg |
Re: Scale Trophy Truck Build This is looking very good! I'd say you will have a very capable truck when finished. I have experimented with offroad jumping with a Stampede and balance really determines how it lands. But its fun playing with it and finding the balance point. In mx jumping, stopping the rear wheel keeps the bike from nosing over but I'm not fast enough with my throttle finger to do that. Good Luck and have fun! |
Re: Scale Trophy Truck Build I think I am switching away from a Slash 2wd based front suspension to a Losi XXX SCT front set up. Any thoughts? If I ran the slash set up, I would cut and narrow the bulk head and run the Protrac arms. If I run the XXX SCT set up, it would be mostly stock. Both set ups would get scale shocks and new shock mounting point on the cage. Also...Do you think this thread should move to the 2.2 forum for a little more traffic? |
Re: Scale Trophy Truck Build Shocks mounts and rear tool area are complete. http://i37.photobucket.com/albums/e9...ps1654b132.jpg |
Re: Scale Trophy Truck Build What a kick @$$ build! Keep the pics coming. Chris |
Re: Scale Trophy Truck Build Any issue with using stock scx10 transmission and center drive shafts on this build? I only plan on running a 2s lipo, but this thing is going to weigh 9-10lbs. I used 3s lipos on my old slash 4x4 and they were really crazy. I don't need to subject this rig to that kind of torture. |
Re: Scale Trophy Truck Build I added an SCX10 transmission, shortened driveshaft, velineon VXL brushless and speed controller tonight. I also started playing with spring rates. I believe I am going with 40mm axial SCX10 springs Green and Red. The stock king springs are simply too light (1.1lb/in) springs. http://i37.photobucket.com/albums/e9...ps31b8510d.jpg |
Re: Scale Trophy Truck Build http://i37.photobucket.com/albums/e9...psc7dd43db.jpg Droop check again! I only need to limit the rear a tiny bit to keep the driveshaft spinning freely at full droop. I shortened the 110mm Kings with 100mm Integy shafts. http://i37.photobucket.com/albums/e9...ps75710ff8.jpg |
Re: Scale Trophy Truck Build |
Re: Scale Trophy Truck Build Nice can't wait to see more of it! What are you going to use for the front? |
Re: Scale Trophy Truck Build I am thinking xxx-sct with a fabbed upper link/shock mount. I bought a roller on ebay, so I guess we'll see when it shows up. |
Re: Scale Trophy Truck Build My fiance made some window nets for me last night. I wanted them to have a little slack in them so they move like a real net. To keep its shape she put a little wire in the net to keep the edges rigid. http://i37.photobucket.com/albums/e9...ps9d168c00.jpg http://i37.photobucket.com/albums/e9...ps3f39ea5a.jpg |
Re: Scale Trophy Truck Build Nice looking build!!! The window nets look sweet!!! |
Re: Scale Trophy Truck Build This is sweet. I had an idea to do one but didn't know where to start so I put it on the build wishlist lol. Looking good can't wait to see it done. |
Re: Scale Trophy Truck Build I got my slash pro-trac front arms last night. I have been spending most of my time getting the rear shock length and mounting points correct. I want 3" of rear travel. I want the tires to just kiss the inside of the body at full compression and I want to use up all of the driveshaft angle I can. I think I am finally there. |
Re: Scale Trophy Truck Build Watching this closely. Looks like it is coming along nicely. |
Re: Scale Trophy Truck Build This thing will be sick once its finished! Seems like every ones build i see just seems far to advanced for my limited skills. |
Re: Scale Trophy Truck Build I'll have to snap some new pics tonight. I have made a few changes. I got some Vanquish products Twin hammers lower rear links, they look amazing but the shock placement on the arm limits travel to just over 3". I wanted 3.5" but I guess 3" is enough. Finally received my xxx-sct front bulkhead and tiebar. I think I can make them work with the Protrac arms. I cut the baseplate to the width of the Losi bulkhead. I also received a pair of RC4WD 100mm King shocks. I need to place one more Ebay order for some finishing details and then just get to work. I can't wait to paint it and finish it up. It's just that darn Rally section on this forum keeps distracting me. I turned my Tamiya Zakspeed Capri TT02 into a Focus Rally car already and I've only had it for a week. |
Re: Scale Trophy Truck Build Sick build man look forward to seeing the end |
Re: Scale Trophy Truck Build Sub! I've had this same idea in my head for years. I like the slash/hpi bit they're not trophy trucks. Def keing my eye on this thread! And sick work so far$ |
Re: Scale Trophy Truck Build I did a little work on the truck this morning. I got the rear suspension buttoned up. I have axial soft and medium springs in the rear (red and green) and 40wt oil. The bypass shock has the stock spring in it and a few drops of oil just for lube. It feels pretty good for a starting point. This thing is heavy! 9lbs so far. Those RC4wd wheels weigh a ton and this thing has 6 of them. http://i37.photobucket.com/albums/e9...ps7a01b0ec.jpg I got the front suspension mocked up. I need to do some grinding on the protrac arms to increase droop and I also need to braze some cage sections in for shock and upper link mounts. http://i37.photobucket.com/albums/e9...ps62074981.jpg http://i37.photobucket.com/albums/e9...ps6ff2208f.jpg I will be making side panels and using the Apache cockpit on this thing so none of the electronics will show. I am kind of getting the itch to work on this thing again. |
Re: Scale Trophy Truck Build I started messing around with ratchet strap ideas http://i37.photobucket.com/albums/e9...ps861d99c7.jpg |
Re: Scale Trophy Truck Build This is looking awesome! ive always wanted to build something like this but never have the funds for how overboard i go. I hope it turns out great! |
Re: Scale Trophy Truck Build Well I decided to dump the SCX10 gearbox and go with a SCTE-TEN 2.0 drivetrain. I plan to step up to a Mamba Max Pro and run 3s Lipos now. I have made progress on the front suspension, I will post up pics from my next mock up. |
Nice build and nice to see people going after real trophy truck builds! Now if one of the rc manufactures would get their heads out of their asses and make something like this! |
Re: Scale Trophy Truck Build I think I made good progress on the front over the last couple days. I figured out how to get RC4WD rims to play with Slash 2wd front spindles, got the arms clearanced for long travel, swapped out shock ends for long travel and got the wheel base figured out. http://i37.photobucket.com/albums/e9...psdf9cbecb.jpg http://i37.photobucket.com/albums/e9...psd1e4440b.jpg http://i37.photobucket.com/albums/e9...psea0e6c0f.jpg I can't wait to finish up brazing and to clean up the chassis for paint. I have a ton of scale detail I am adding. I found a solid file for a Ford Coyote 5.0 engine and I am having one printed on a 3D printer at work. Guess I need to order up a Raptor body to go with it! |

Re: Scale Trophy Truck Build I got a few more parts in. I need to finish up my brazing on the front but am lacking motivation. http://i37.photobucket.com/albums/e9...ps084698ee.jpg http://i37.photobucket.com/albums/e9...ps55c369a2.jpg http://i37.photobucket.com/albums/e9...ps045bbeec.jpg |
Re: Scale Trophy Truck Build Very cool build!! |
Re: Scale Trophy Truck Build and then... |
Re: Scale Trophy Truck Build That truck was coming out so nice . I ordered the same tires also for my project. I can't wait to see this done . Keep up the good work . |
Pretty awesome build Sent from my XT1080 using Tapatalk |
