yeah i brake my shafts from time to time, mostly front, make sure you have limiters on the rear shocks so it doesnt compress fully. I run on high grip tracks tho.

I was happy with my new XB4 on its maiden voyage on an indoor track this past Sat, but struggled with the rear end getting loose under full throttle (RSX / 6.5 Motor). I have everything turned down as much as possible on the ESC and even backed out a little expo on the RX throttle and it's still getting loose and crazy fast . I started with 20/81 gearing and went up to 22/81 hoping to take some of the low end edge away, but it didn't. With this all said I managed to pull the win at my local track and had the fastest lap time of the day in over all other classes. Anyone else have a similar issue and tame it?

I am thinking about getting into the wheeler class. This is the only buggy that looks good to me. Is there a spring chart anywhere to show the firmness?

Maybe it's an apples to oranges type comparison, but I notice some of the things I've had success with / others are too with 1:8 scale (Tekno EB-48) doesn't apply to the 1:10 scale XB4. Specifically roll center changes and their effects on each vehicle. I notice everyone seems to run the rear arm pivots towards the top of the toe plates with the XB4 (with +2 toe plates) and with the EB-48 most run them as low as possible to get better traction (and even use special lowering inserts-LRC). Would this be due to the difference in weight and layout balance between the two and the one needing something the other doesn't? I figured that I'd need to try the same things that worked with my 1:8 buggy to get the same results, but am finding that most are reporting success doing the opposite from what I have done in 1:8 buggy. I only have a day on the XB4 so I'm limited with my setup knowledge, but this was bothering me as most of the setups I see conflict with my Limited overall experience.

Stiffer front springs 3 dot or Losi black.
Softer rear springs 1 dot or something equivalent in rate.
Remove rear spacer under diff case.
No front sway bar and 1.4mm rear or another option is run smaller rear sway bar 1.0mm and stiffer front sway bar 1.4mm. I've had good results either way. I run a 5.5 turn on med bite clay and the car has plenty of rear grip. Almost too much with the Vik setup. Had to go to 7k front diff fluid yesterday to get more off power steering.
