Default How to keep the front end planted.

I am running a brushless vxl rustler with 3S lipos, and it's almost annoying driving it with this much power! It makes it very difficult to drive because the front end stays so light which makes it very difficult to steer. I am jealous of all my 4x4 slash buddies who can mash the throttle and not worry about looping out as much.

In the rear I am running big bore shocks, blue springs, largest spacer, with the suspension set all the way in to put the rear as tall as possible. Front is stock with blue springs, largest spacer, set all the way out (as low as possible). Both filled with 40wt oil.

I'd like to think that keeping the front end planted isn't completely caused by the 2wd. What suspension is everyone using to make this much power at least manageable? Maybe gearing? It has the medium setting (whatever that means ) My lipos are 4000 and 5000mah

+1. Yes that would be way to much power for your application.

+1, you only want to run a 2s

also add some weight to the front. Anywhere from 4-6 oz
depending on your style.

3S are like crack... I'm addicted to them! I like having the power whenever I need it, I'm just trying to get the tires to hook!

That's weird, three people told you what your issue is coming from.......but you don't like their answer and don't want to take their advise.......its not so much that 3S is like crack....its more like you want it to be something else. If I was one of the people who took the time and tried to help you by responding to your post.....I would avoid responding to any of your questions/posts ever again. http://www.youtube.com/watch?v=APwfZYO1di4

Power isn't the problem, the fun part of having a Rustler is driving with way too much power and trying to figure out how fast you can get it to go while never actually getting there.

Some people put something heavy on the front end to keep it from coming up as much, also soften the rear end so it goes down a lot when you hit the throttle instead of the front end coming up. Set the slipper some, but that doesn't help much when you can wheelie at 30mph. You can also get rear tires that don't get a lot of traction so instead of lifting up the front the tires will slip, but you also have the problem of losing traction at high speeds. Just remember to work the throttle finger and there's more speeds than stop and full throttle.

I had the same problem in my Rustler. Here is what I would recommend

1. Lower the rear as much as possible and use soft springs. This will make it more difficult to wheelie.
2. Loosen your slipper clutch.
3. Reduce your torque. Use a smaller spur or larger pinion. Keep in mind that doing this will increase top speed and increase motor temperature.
4. Control your throttle finger.

Post a question in the Radios and Electronics forum. Ask about adjustments you can make to the Traxxus VXL esc that cut back on the initial power. Some manufacturers call it punch controll. You might be able to tone it down enough and still keep your top speed. Also, gear taller and maybe loosen your slipper a little and put some weight up front. If that doesn't do it, practice, practice, practice easing up on the throttle on initial accelleration or go to 2 cell LiPo. Borrow a 2 cell to see if you can live with it.
