Alright im new to this web site, so if you want you can add me as a friend. I have a traxxas slash 2wd and it is a vxl and i was wondering what the best, fast, and coolest gearing there is because i dont like it to heat up either. I was also wondering what i can do about my steering because it turns to the right well and it dosent turn to the left not so well. Thanks
Are you in Grants Pass? If you are around this weekend there are usually people at B Street or Harbeck who would look at it for you.
We have a couple members in the Medford area that may be able to help if you haven't had and luck yet.
I don't have a Slash, but I've had plenty of other vehicles so hopefully I might be able to steer you in the right direction. (No pun intended.) Gearing: is mostly based on motor temperature. You're smart for not wanting to run it too hot, that can damage your motor, overheat your ESC and put strain on your batteries. Since the Slash comes RTR, I'd just stick with whatever the stock gearing is unless you feel like you want more torque. Drop your pinion down a tooth or two and you'll have less top speed, but more torque and acceleration. Go up a tooth or two and you'll get more top speed, but loose acceleration and run-time. Be careful moving up on the pinion gear because this is what causes the motor to get too hot. The "rule of thumb" I've heard tossed around is that you want to be able to hold onto the end of the motor for about 3 to 5 seconds before it really starts to feel hot. If you can't hold it for at least 3 seconds it's too hot. As for your steering problem: It could be all kinds of different things, but here's where to start looking. This happened to me after building my new TLR 22T. I got great steering going left, but almost none going right. Turns out something was bound up inside my steering rack that kept the servo from pushing the wheels that direction. I ran some light oil down the rack and it freed up and worked fine. Be sure to check out the whole steering system and see if there's anything binding it up. Check all the moving parts and give them a little bit of light oil or WD-40. If that doesn't fix it you might look at your steering linkage (also called turnbuckles). Sometimes one of them can be bent or severely over/under-tightened which will throw all your steering geometry off. Lastly, you could look at the steering servo. I had a brand-new servo not spin in one direction once. Generally, when a servo breaks it's because a gear inside it stripped and needs to be replaced, but in that case the whole servo would be dead and wouldn't turn the wheels at all. (At least in my experience.) My servo that arrived DOA had a broken motor that would turn only one way. I hope this points you in the right direction. Let me know if you have any other questions, I've been doing this hobby for more than 10 years and have gone through my fair share of cars and gear!
