Default slash 4x4 question

how are you guys getting your 4x4;s to jump right? mine and all the other guys i race with cant figure it out, Everytime I jump my truck nosedive's. For this past weekend's race i rigged up a weight for the back bmper, it woked a little but i need to find a way to get it right through setup, i have Big bore shocks ... and ideas?

I had the same problem and what I figured out is that everyone that has a 4wd truck has the same problem. I run very soft suspension in the front on mine and I have also got comfortable with my throttle response also. Right before I come up to a jump, I let up a little and then at the last sec, I punch it. Also using the throttle in the air helps too. It will just take practice. I am still getting used to mine also.

I've seen this happen a lot too. I had this happen with everyone of our 4x4 Slash's. Once I changed the shock fluid 55 front, 60 rear and threaded out the rod ends on the shock to extend the range of the shocks operation the truck jumped a lot better.

Keep practicing your jumps and alter your throttle during your approach.

Hope this helps

when the front end dives on jumps, it's either driver error by chopping the throttle on the jump face, or the front shocks have too thick of oil/rear has too thin of oil. This allows the spring to give "pop" to the rear end that the front doesn't receive. As the shock oils are so relative to what holes you are running the shocks in, it's hard to give a suggestion....but you want the front to feel slightly springy compared to the rear when it's on the pit board.

Also you gotta change your shock oil. I run 50 wt all around. And it it's stilll nose diving you gotta put some throttle trim on it.

My guess and it's only a guess is that most guys who are now running 4x4 sct have probly never driven or owned a 4wd before, (not the most common thing before now) as a result they drive WAY different than any 2wd. 4wd is way more sensitive and responsive to throttle input, especially in the air. Long story short work on using the throttle and then fine tune it with springs and shock oils..just my $.02

the key to jumping these is to give yourself at least 1/2 of the throttle left when launching. this gives you plenty of play to manuver it in the air. it took awhile but i have mine jumping well now.

yeah +1 on the holding throttle some when taking off. The motor has a lot of drag brake built in so if you chop the throttle taking off or even in the air, you are going to nose dive or do a front flip.

It will just take practice getting used to it.

I also noticed with mine before i installed the MMM system, installing RPM arms and bumpers really made the truck handle jumps better for whatever reason.
