Upgraded steering

[acerblue]

So I have noticed that my stock steering is very touchy. As well as it has a hard time electronically when turning to the left. It will wan to turn right when turning full left.

What is a nice upgrade go steering? And what all do I neeed to get the job done?

do you have a single servo setup or a dual? even though most are against it - i'd go dual servo for steering..get some high torque steering servo's and go with that...i'd did that on mine and it made the truck turn a lot better...issue with single servo is that one way if you let off the steering it doesn't come back to center very well...you can also upgrade your reciever battery pack to a higher Mah rating to make sure it has the juice to run it...

issue with single servo is that one way if you let off the steering it doesn't come back to center very well

Please explain. A servo will always come back to center as long as it's not broke in some way. Steering itself coming back to center is a function of rod adjustment and trim settings which is an issue with dual or single servo setups.

.........

A very real problem with a dual steering servo setup is that one servo will almost always struggle to it's neutral position against the other servo. I don't car how well you fiddle with the linkage and trim, one of them will always end up buzzing which eventually leads to failure.

Best setup I have found for a Revo is a single high torgue 300oz or better servo such as the Hitec 7955 with the Traxxas heavy duty saver spring and the Proline single steering arm.

Agree, that is the setup I am using now in my Revo and it works perfectly. I found with the twin servo setup even with high torque servos the servos seems to be "fighting" with each other and have a hard time return to center perfectly. I change to one servo setup and the issue is solved.

I have no idea how to change to a one servo setup... so if you guys could post detailed instructions on how to do it and specific servos that are the best to use... I would appriciate it.

i disagree - if you have your truck setup right - both servos at neutral when the linkage is off - and you have the arms/turnbuckles adjusted right then there should be no fight and no buzzing servo that you hear. The servos are not powered as much when returning to neutral - so if your truck is turned and rolling hard and you just let off the stick to allow it to go back to nuetral then there is almost no power being used to pull it back to center - with 2 servos at least they are both pulling back to center and i find my truck goes back straight if i just let off the steering much faster - one servo saves weight and drag on the battery pack for sure..but i've tried both setups and nothing i've found is better than 2 decent servos pulling on the steering..it has much crisper trun in and goes back straight without any counter steering for me...maybe just my experiences but that is my preferred setup...

I run a single servo on my track revo and dual on my basher less need for steering on the basher---

How ever i agree with rob on the servo issue--- I have yet to see a revo with dual not burn out a servo at some point-- Not saying it wont work well for a while-- but you are 100% better off with a High torque single servo then dual servos---

Yes, with perfect setup the dual servo setup should work better. But you know in real work situation nothing works perfectly. Due to the slop in the servo saver, ball link, electronic equipment inside the servo,etc. It is very hard to get to servo working identically. So when I first got my Revo I use the stock 2 servo setup. When I start racing it I prefer the single servo setup. Just my 2 cents.

Yall really are not helping me here with my questions. All I see is debates. No one trying to help the noob OP. I was under the impression I could get some help via this forums seems traxxas fora require paid emails for reg and there is not a single hobby shop in my town. *sigh*

I have so much I would like to do toy truck but no one to REALLY help. I don't know much about mechanics or anything advanced. He'll I have a hard time taking stuff off and remembering how to put it back together right the first time, but I want to learn. If I can't get it on this forum where can I find some experienced people with mods and upgrades that will talk me through stuff.

What is a nice upgrade go steering?

If you are interested in doing a single servo conversion, here are the parts you will need.

Proline Servo Arm

Heavy Duty Saver Spring
http://www3.towerhobbies.com/cgi-bin/wti0001p?&I=LXHGE0&P=M

Servo (This servo is what I like to use. There are cheaper options that put out less torque. It's a matter of what's in your budget.)
http://www3.towerhobbies.com/cgi-bin/wti0001p?&I=LXTHR3&P=ML

And what all do I neeed to get the job done?

Remove the old steering setup and install the new components.

Be sure to set the steering endpoints and trims back to zero on your transmitter if applicable and plug in the new steering servo so it gets centered before installing the servo arm.

If you want to do this conversion it is a really easy process that is self explanatory once you get started. The exploded view in your manual is helpful. I can walk you through it if you decide to go this route.

Thank you rob for some finally positive feed back. Parts are in shopping list for order. Budget isn't a problem. I'm military hehe.

Just in case for anyone else, the hitec 985MG will do the job really well as a single servo in the revo as well.

:goodpost:
I agree with him 100 % i have dual servos on my 3.3 revo and i just put the second servo on my Merv and it turns soo much faster than it used too, i like having dual servos for the simple fact that if by chance it is under a little bit of a bind the second servo makes up for the interference and compensates and makes the wheels turn when they are supposed too, or need too, i hate to keep this debate going but i just wanted to put my input it for arguments sake (although its not really an argument, just a discussion on preferences), but as i like to say "To each their own"
