If you have stock...

Not saying it wont effect your steering handling because it will and that is another discussion..., so just for jumps... adjusting your springs and/or oil weight can have an effect,combined with thottle control. Anti squat could effect as well, but wont go into that. Its all about how you approach and release from the jump/bump.

The basic concept is you want your rear end to sag more or quicker than the front (causing the front to be higher) or you want a quicker rebound in the front.(quicker spring in the front will keep your nose up)

So depending your ride height, first thing I would do if I was on the track racing for a quick fix, is lower the rear end i.e. move the shock collars up so your springs are not as compressed. This however is for a minor adjustment. It might be just enough though.

I haven't heard of anybody running lower than a 27mm ride height, so I wouldn't lower your rear end much more than that using the spring collars.

if you have done all that already, on your throttle control, are you applying constant throttle over the jump? If so, then try giving a little extra blip of throttle right at the top(idea is to get your rear end to sag a little more)

If you are have time and can adjust your oil(thicker front or lower rear).
Stock is 30wt all around. Generally its more so with 2wd drive, but typically the front is a little heavier weight oil in the front than in the back. On a 4wd usually its more even, most don't go much different that 2.5wt difference from front to back.

So there are some ideas, give us a little more info and we might be able to help you out more.

However one thing I did notice for people copying others setup is Lane's has 2.5 toe-in in the rear. Correct me if I'm wrong but you can only do that if you have the Adjustable Rear Hinge Pin Holder Set [LOSB4113].

so you are right your setup is probably more out of the box friendly.

Might be useful to post if you want to do Dunford setup you at min:

Losi Piston Pack [LOSB2909]
Losi Rear Shock Spring Tuning Set [LOSB2963]
Losi Front Shock Spring Tuning Set [LOSB2959]
Losi Silicone Differential Fluid (5,000cs) [LOSA5280]
Losi Silicone Differential Fluid (3,000cs) [LOSA5279]
Losi Certified Shock Fluid (30wt) [LOSA5224] (dont need if you don't plan on re-doing your oil anytime soon - stock is 30wt)
Losi Silicone Shock Oil (27.5wt) [LOSA5214]
Sway Bars(can use stock, but I believe they need to be switched to opposite ends)

So Basically a Piston Pack, front and rear springs, your fluids and you can do exactly Dunford setup from box stock.

Lanes I believe you also need:

Adjustable Rear Hinge Pin Holder Set [LOSB4113] ( to get the rear 2.5 toe in)
1 more thing of diff fluid (7,000cs) for the front diff

But I agree with you Ryan.

I do have the protek body that has the vents...im going to next time I'm out try hitting the throttle at the highest point, i think i was hitting it a bit lat but there were some times i got and she rolled so smoothly down the back end of the jump....need to master that! lol

Thanks guys for the input!

But a mid size jump I should be able to land fairly flat with constant throttle, and then adjust my thottle control based on the bigger jumps.

Hope that helps some to gauge. I live up in the Pacific Northwest, so Coral Springs is a little far for me . I will take a look though and see if I can see anything.

Thanks!!

However, the 4000 has unnecessary torque that goes un-used. If I try to use it, it just wears out tires.

I am considering getting the 5200 kv sensored 401 tenshock motor. I did a search on it and did not find many testimonials.

I know it is a lot of motor. It is ok if it is to fast. I do not get carried away with the throttle and only use it when I need it.

Has anyone tried this motor out?
