Model Forum / Radio Controlled / Land Models / November 2004Nitro Rustler Handling
Howdy guys, wondering if anyone out there has some tips for setting up a nitro ST. Mine is a Nitro Rustler. Its running great, but comparing to my old Inferno, I'm finding it super hard to drive. I'm mostly on a dusty hard track. Problem 1: The front end seems to just pogo up and down whenever there is any speed on. Problem 2: The problem other is rear end traction - the slightest application of throttle lights the back up and it just wants to swap ends. I've already replaced the stock rears with Dirt Hawgs which has made a small improvement. Coming down the main straight the back is just spinning up wildly and threatening to step out. While this is happening, the front end is only alternately touching the ground, so it is damn near impossible - wild over corrections all the time. I've considered moving the battery pack to the front shock tower to keep the front down, but I think that would further decrease rear traction even more? I realise that this is not XXX-NT or RC10GT, but I think I should be able to get at least SOME improvement. So, grateful for any suggestions, ideas, replacements etc etc - let me know what you think! Mike Hey mike, I just got to see two new rustler with the 2.5 motors run at my home track and i noticed the same problem you are having. For one thing it looks like they have street tires on the front. Keep them for street tires and try Proline edge tires for the front m1 compound. Also i noticed that they had lots of power down the straight making the front leave the ground only advice i can see is loosen the slipper clutch or let of the throttle or you could buy lead weight at a hobby shop and stick them in the front. Also try Proline bowties in the rear they are good in any clay. Rob the only thing i can really say is that a 1/8 buggy is no comparison for a 1/10 nitro st. the stadium trucks will always be a little wild and considerably harder to control than a 4wd buggy. however, this should not be so extreme that you can't handle it. loosen the slipper clutch a little bit but not too much or you'll burn it up and just keep feathering the throttle. you'll get better with practice. my rc10gt has similar problems but not too bad that i can't handle it. also, check to see if you can make the wheelbase any longer. mine had spacers in front of the rear hubs that you could move to the front or back to change the wheelbase. a longer wheelbase will be more stable and increase steering. i also had to had some weights to my front end to keep it planted. hope this helps. jack > Howdy guys, wondering if anyone out there has some tips for setting up a > nitro ST.

Agreed. ST's are also easier to maintain and are more fuel efficient. however, this should not be > so extreme that you can't handle it. loosen the slipper clutch a little bit > but not too much or you'll burn it up and just keep feathering the throttle. > you'll get better with practice. All good advice. my rc10gt has similar problems but not too > bad that i can't handle it. also, check to see if you can make the wheelbase > any longer. mine had spacers in front of the rear hubs that you could move > to the front or back to change the wheelbase. a longer wheelbase will be > more stable and increase steering. I'd go against this, because one big problem is no rear traction. Moving the rear axles back will shift weight forward and make the fishtailing even worse. i also had to had some weights to my > front end to keep it planted. hope this helps. Ditto, for the same reasons. Justin > jack As far as the tires... The Dirt Hawgs are a good all round multi surface tire, but have limited traction. Try some Gladiator 2 tires for offroad surfaces. I was well pleased with them and they lasted way longer than any type of step-pin tire. You can also try some different suspension settings. > Howdy guys, wondering if anyone out there has some tips for setting up a > nitro ST. Mine is a Nitro Rustler.

The Nitro Rustler with the Traxxas 2.5 is way overpowerd. You will lift the front end on acceleration no matter what you do. Letting out the slipper can help, but don't let it out too far or else you will burn it up. Also you can try putting slightly lighter shock oil in the front to get better traction. I'd say maybe 30wt. > Problem 2: > > The problem other is rear end traction - the slightest application of > throttle lights the back up and it just wants to swap ends. I've already > replaced the stock rears with Dirt Hawgs which has made a small improvement. I'd look into getting track specific tires, and then loosen up the ball differential just a hair. If you have a gear differential then this is not an issue, and make sure that your slipper is looser than your ball differential. When you turn the wheels and hold the spur gear, you should be able to see the slipper clutch turning. > Coming down the main straight the back is just spinning up wildly and > threatening to step out.

You can help this by running a slight toe-in, maybe at 1 degree or so. > I've considered moving the battery pack to the front shock tower to keep the > front down, but I think that would further decrease rear traction even more? Yes. Traction will follow the weight when you shift your weight forward. > I realise that this is not XXX-NT or RC10GT, but I think I should be able to > get at least SOME improvement.

Justin Thanks guys, plenty of good ideas there! > Howdy guys, wondering if anyone out there has some tips for setting up a > nitro ST. Mine is a Nitro Rustler.
