Cool, but why does the rear wheel keep hoping up on the left side? Something does not seem right with that. :?

Think thats when it was wheelieing in reverse? The shocks are so laid down theyre really soft so it twists easy.

I noticed it when it was going in forward more. Just seems weird is all, but it looks like it handles really well off the jump and has really good turning radius.

Ya turns well even with the back end locked out. Ill watch it some more tomorrow and see, but still think its the shock position. The 4" are too long, may get some 3" revos or something.

Made some sway bars today and moved the 4 link mounting points to the outside of the chassis. Almost cured that back wheel flop, it only happens now under full breaking at high speeds while turning. Think I can just switch up to a thicker sway bar and see what happens.

Also ran the wiring through the chassis instead of over so it looks a lot neater too~

Thanks, getting close to being viable now. Nothing I enjoy more than building something like this from the ground up.

I think that will help with the wheel hop. =D> Nice job on this build!

Doubled up on the rear sway bar with a second bar, helped a lot. Stole the body off my gecko since I don't crawl much any more.

Next step balance the tires and up the batteries to 4S and maybe 5S. Been reading the evx2 will handle it.

I've heard the same, but your motors won't like it too well.
......says the guy who tried 6S..... :mrgreen:

Truck is looking good! :thumbsup:

Looks good with that body on it. For a minute there I thought one off your links was broken, but it looks to be a stick laying under it.

When you going to upload a new video of it? Curious to see how it runs with the dual sway bars in the rear.

Put in 4S today but didn't get a good run. It was fast and made a lot of power but I snapped the front drive shaft again and as you can see in the videos it was leaning badly. The zip ties holding the sway bars on the back left side actually broke. Guess I'll get some thicker ones. All of this happened mid first video so the second one is rear wheel drive and with a broken sway bar mount.

Actually found some emax 5mm outputs so can fix my drive shafts right this time~ Then maybe I'll try the 5s.

Interesting. It sure does lean to the drivers side, A lot and that pesky front right sure likes to lift up too. To fix that try using some stiffer springs on that side in the rear. This is common with shaft trucks with the torque twist. You might be able to add some preload spacers too to stiffen it up more. I had the same issue with my Comp crawler as well and doing what I mentioned does help, a lot!
