I wanna be Dave
I've got 3 unfinished trucks sitting on my workbench, as well as a crawler course I'm trying to relocate in the backyard, so what's one more project?
After tearing down 2 built trucks to build the Belly Dragger Sawback (with all the good parts) I had enough parts left over to build the second Sawback. Nothing too fancy, its mostly stock parts with a few twists here and there to keep it interesting. I had to resist my typical urges to cut up some aluminum and build a chassis.
Stock chassis with some flat black. I assembled it first, then painted so the color is consistent. I'm not a scale snob at all, but it makes a world of difference getting rid of the chrome.
My biggest beef with the GS01 chassis is the noise. The transmission sounds like I'm driving a blender through the woods. Compared to the SCX10II and especially the Ascender, the racket was driving me crazy. I tore down the trans and played with some 5mm shims to see if they made a difference. I found the counter gear was a bit chewed up...not sure why, looked like a molding issue ilo a debris issue. So I mixed and matched gears from 2 transmissions, played with some shims, and now the trans is amazingly quiet. Testing it on the workbench with 3v is smooth and almost silent. Amazing what a few shims can do.
Hung the rear axle on. Axle has brass inserts, Axial shocks with 40wt. oil and is set up with a large helper spring. The Sports body is a bit heavy, so the extra spring works out nice. I made an anti-wrap link when I initially built the kit and it seems to be working well. The springs have been on a few trail runs, and they look pretty good still.
Went a bit different up front - set up a 4 link ilo the leafs. It allowed me to push the front wheels out about 10mm or so...larger tires tended to rub the back of the fenders under compression and it never looked right to me. The geometry leaves a bit to be desired, but I think as a front axle, it'll work ok.
Took some messing around, but I got good caster angle, pinion angle, and a nice range of motion. Axle has brass inserts, and another SCX10 shock filled with 40wt. does the duties here too. Left the steering servo on the axle for now, though I have room for CMS later on if I decide to go that route.
And we're rolling with Sport bumpers and some Redcat Iroks stuffed with 4.5 soft DS foams and a bit of weight to offset that tall body. Tires feel GREAT....as good as any I've got on any truck. We'll see how they do though just testing around the basement I've got high expectations....
Wired up...running out of crawler stuff, so an silvercan will have to do. It's geared down with a 9t pinion, so should work out very well. (I have a 35t on the way) Battery can go up front or out back - starting with it up front for now.
Next up - bodywork. Can't ever go wrong with Tamiya copper....."thumbsup"
