Inhance Steering

[unccpathfinder]

My new/used stampede has a Traxxas 2.5 transplant done on it and I have locked the differential (or the equivalent) I know this makes it push a little but prior to locking it steering wasn't great...

but for the most part under any acceleration the front wheels have no load on them and cannot turn...under braking conditions I get weight transfered to the front wheels and she turns decently but still not great

I'm running the traxxas tires which seem to do ok on gravel and in the dirt but on grass and asphalt seem to lack some


Will adding weight to increase the contact patch on the front wheels?

how about increasing my tie rod (or idler arms not sure of the R/C terms) lengths to increase the amount of wheel cut available?

Thanks

playing with with toe setting may help, more weight up front almost always helps, and locking the rear diff hurt very badly... I've never had one of these trucks so I'm not sure what diff it has, but if its ajustable then loosend it up a bit.

changeing the tierods wont really give you more cut, but a longer servo arm may, (if you have room)

If memory serves, the diff in the ol' Stampede was a planetary setup. Companies like Thorp and RRP used to make a ball diff upgrade for it, but that was a long time ago.

Aside from making it so the diff "works" (isn't locked like a posi-trans), the only real way to improve the steering on the truck is to lower the suspension down so the arms set level. This will allow the truck to steer quite a bit better.

The stampede was pretty much designed to be a wheelie-on-demand truck, with moderate jumping and speed runs every now and again.

I just went out and tuned on it some and now its even more ridiculous...It was runny way rich and very sluggish now if i pull the throttle it'll pretty much flip itself backwards...

I will probably go back to an open (or I'm guessing positrack) b/c I keep on ripping the U joints out of the rear shafts

Thanks for the inputs...Now I have to figure out the tuning on this thing b/c I have it about as rich as possible and it still gets crazy hot like 270F-290F got plenty of blue smoke and nice smooth idle but she's hot as a firecracker
