So after building the SCX10 II builders kit, upgrading the usual bits, and having entirely too much fun, I decided to build an lcg chassis rig to potentially compete in class 2.
Equipment:
G-Speed TGH-V3 carbon fiber chassis
GSPEED TGH-V3 electronics tray sliders
Team Garage Hack dual servo mount
Team Garage Hack TGH-HH forward motor mount
With 15% od transfer case
Vanquish driveshafts
Boom Racing top shaft
InTheWorks RC stainless high clearance links
3Brothers RC Yellowjacket 1500kv outrunner
Mamba Micro X
HeyOK No Brainer BEC
HiTec 7955tg
AR44 axles, with cromoly axle shafts, vanquish gears, Locked Up RC FI lockers.
Stock 8/30 gears in the rear, overdrive gears in the front axle
SSD brass knuckles
Brass diff covers front and rear
DLux Dravtech short shocks, soft springs in fron, medium in the rear, IIRC
Pro-Line Power Wagon body shell, cut down quite a bit.
Salinas Design power wagon drop bed.
Current wheels are chinese aluminum beadlocks off Amazon.
Crawler Innovations foams, CWR-2024 front, CWR-2025 rear.
Pro-Line tires, Hyrax and Krawler KX's, both in predator compound.
The Crawl Space stinger front bumper, and one of their shorter front bumpers on the rear.
So, a few thoughts about the build, and the performance:
Holy hell it's good, so damn good. Great sidehilling, much improved breakovers, and wonderful stability overall. I am enjoying it so very much.
The 'all up' weight with 850mAh 3s pack is 5lbs 8oz. I really wanted to keep it under 6lbs.
The quality of the Chassis, motor mount, servo mount, etc. are all quite nice. The build was very easy, especially thanks to a few threads here, specifically Topher's g-speed v3 build and his sherpa build.
The dravtech shocks work better than anything I've ever used, hands down. I bought the Channel Lock brand snap ring pliers and a pair of shock pliers. I can not recommend highly enough to buy those when assembling these shocks, it made it very easy and painless. Eric has a video on youtube showing the assembly, this was a great resource as well.
The CI foams are worth every penny, and more. They are so much better than the ProLine two stage foams I was using. I vent my tires, with 2, ~2mm holes, 180 degrees apart, between treads. The Hyrax's work incredibly well in this area (Central Texas), the Krawler KX's work well, but so far I think the Hyrax's are a bit better. I was really hoping the KX's would be better, as they certainly look awesome.
Todo's:
I have some slop in my axles, mostly the front axle. It's mostly noticeable when climbing up, and I have to stop to wiggle or something. There is a bit off 'roll back' that annoys the hell out of me. I'm hoping I can shim the pinion further down into the ring gear and eliminate the slop. I may buy more lockers to try as well.
ESC tweaking. I just got a castle link, and I'm going to program my esc a bit more to tweak the performance. The reverse comes on too strong for my liking.
The low speed control of the 3bros yellojacket is awesome, it really is quite impressive. The whine isn't all that loud, and doesn't bother me a bit. The weight savings between the yellowjacket and my old HH 550 is significant.
Wiring cleanup. When I get the direct servo I can ditch the BEC. I plan to clean up the wiring quite a bit at that point.
Future upgrades:
3 Bros RC G13 servo
3 Bros RC overland winch
SSD Pro44 axles, brass chubs in the front for a bit more weight.
Lighter wheels
More single malt and japanese beer.
Different body shell. I love the power wagon, but wan't something different. I really like the MST FJ45 body, I might have to give that sucker a try.
Portals.... so this is in and out of my mind constantly. Which pretty much means I'll try some portals on this rig, or maybe buid another, at some point. I'm still researching which portals, gearing, etc. to ensure I get at least as much OD in front as I have now (~22.5% I think).
Overall I could not be happier with this rig, the build, the quality of the components and of course, the performance.
Some poorly taken pictures.
