I wanted to give another class a go at my local track and really enjoyed watching the stadium trucks... class isn't that big either, so they could use the extra drivers. I figured this would be a good opportunity to handicap myself and force me to become a better driver since my Tekno EB410.2 pretty much drives itself. I decided on a 2wd rustler and threw a HobbyWing 13.5t combo in it along with a cheapie high speed servo from eBay.... the one car that everyone screams not to buy for racing. Something that will actually take skill to drive fast... I'm not looking to win races, I'm just looking for a challenge in both driving and the tuning department so I can get good at setting up a car.
First and foremost the track conditions are reclaimed carpet of various piles and it's laid out on a gravel pad, so it's not exactly smooth either. Does anyone have experience with running a Rustler on similar tracks and what have you done to improve its handling? Biggest problem I have right now is traction rolling... I've cut down on it a lot with changes to the geometry, but I'm fairly new to shock tuning and I feel that's the next step. Only thing I've done so far shock wise is put some 50wt fluid in the rear shock, which cut down on the traction rolling quite a bit and made the car handle the doubles without bucking itself off the track. But it'll still roll it if I push hard into the corners. Springs are all stock with zero preload spacers and the ride height is way too high compared to the other stadium trucks at the track... it almost feels like I need to run stiffer springs as there is a lot of body roll, but I fear that will raise the ride height to the point I'll be right back at square one. I'm sure the answer is obvious, I'm just overlooking it... any pointers from some experienced racers? A good starting point for spring rate?
"Upgrades" that I have done:
- Slash 2wd rear arms for some much needed rear toe.
- I got a set of tires that have been working on the track for everyone else.
- Adjustable links, I have just a little bit of negative camber in the rear and I've set the front toe out 1-2 degrees. Steering has improved dramatically and it doesn't feel like I'm driving a dump truck through the track anymore.
- I have some CF towers on order so I can actually get some mounting points for the shocks as well.
