Another Yeti Score build!

[Zac_F71]

Well guys lost out on an SC10 SCT truck (going for more than I want to pay) SO made an offer on this Yeti Score RTR chassis on eBay for $215 shipped and got it! #racetruck haha

Going to make it a light weight, decent handling race truck. Typical SCT wheel/tires, body, and a few upgrades! Bought decals for a Rob MacCachren Mopar truck with another Pro-Line Ram 2500 body.

Hot Racing front sway bar
Hot Racing 43/13 gears
Traxxas turnbuckles for camber/steering
Twin Hammers rear links
Ditch the fuel cell (cut down aluminum links in place)
Axial narrow 12mm hubs
SSD servo arm
SSD Yeti D60 centered housing
Yeah Racing titanium steering link
Reedy shorty 2s lipo
Savox servo
SV3/5700kv system from my other Yeti
Traxxas black/blue 2.2/3.0 wheels
Jconcepts Dirtwebs (golds)
Few other things!

Looking forward to this one Rob Mac is one of my favourites.

Nice! Me too! My other truck sadly is to heavy for the SV3/5700kv SO I decided to save up and buy an 1/8 scale combo for it. So I'm donating the SV3/5700, and a few other parts from my other truck to build another ahaha

Wanted to do a light weight race style truck out of one of these to see if it could hang with the likes of race style SCT's on a clay track haha.

I doubt it, but it'll look cooler.

That's ok I'm a crappy RC driver on a track anyway ahaha

Even a 'lightweight' yeti will be at a disadvantage to an SCT in gearing, weight, balance, jumping, and having a solid rear axle.

If you are still set on spending your money to run a yeti against SCTs, here's my comments:
- dial out as much anti-squat as you can stand from the rear suspension.
- unlock the rear diff - I have heard that the spider gears won't last long on the track, but will will reduce 'fishtailing'
- use the stiffest blue-dot axial springs, and dampen well; you can run the suspension lower with less bottoming
- the fuel cell is integral to the chassis cage stiffness
- find out what tires work for your particular track, and get those.

1. Noted
2. good idea! Will do that! (swap front dif for rear ahaha)
3. Noted
4. fuel cell is going to be replaced by aluminum threaded links
5. It's an indoor clay track almost blue groove - Jconcepts Dirt Webs golds are the plan

[Zac_F71]

Said F it and ordered the parts! Once the chassis shows up the modding will begin! Going to try to mount the battery further in the chassis to lower the center of gravity a bit. Very little time left to wrench sadly as it gets nicer out my 1:1 will get all of my attention here!
