What is the purpose of running dual servoes for the steering? I have a pro1 sprint car and any time you touch anything solid, the servo arms flip and make turning impossible. I have even tried making one servo arm solid, then it just caused the steering to be off center. I am really comntimplating swithching to a single 1/4 scale servo. I know that hitting things will still cause turning problems, but I wont have to try and figure out which one is causing the problem. I run on a pretty small dirt track that is fun as heck,, but the walls are not friendly.

dual servos are better no matter if they are larger or smaller just in case 1 craps out on sprints they are fragile you dont need to hit anything anyway but i know it happens there are a few guys on here that probly can give you some good info on your problem like fred or randy baker

sounds like 1 of 2 things have happened. either you have your front end way out of adjustment or you need to stop hitting things. i would adjust the steering linkage personally..i like hitting things. sometimes makes the car turn better!!!:woohoo:

I've seen the body on BIGSHOW's car, I can say he hits things alot. LOL.:wave:

I was wondering the same thing about this question, I have one servo on my Baja and have had no problems with it. And if you think BIGSHOW hit things, you haven't seen me drive, if that's what you call it.

thanx for the support stivy!! lol that body has definately seen better days. i did finally run the blue deuce saturday night:woohoo:

I've got to drive the blue deuce a couple of times. How you do with yours?

The first problem with running only one servo is that you only have one servo saver and one servo spline, the torque of the servo is not relevent. You will snap off the spline on most servos. With two servos you divide the impact between two servo savers and servo splines. I've been there done that with an older sprint car.
Hope this helps,

1/5 scale cars use a very good servo saver that does not mount to the servo. It is a seperate unit... just like the old raco cars. Problem is you would need to reconfigure the front end of a sprint for it to work. The servo savers that mount directly onto the servo are all designed for small scale cars.

Make a link between both servo savers and this should take care of one or the other trying to cam over . Had the same problem you described and making this link seems to have taken care of the problem .

Thanks for the info, Never thought about the spreading force aspect. I have come up with a bunch of different mounting patterns but all seem to have the same problem, but never thought about hooking the servo arms together. I don't have my steering full turn so I bet the llink between the two might work for me. thanks

hey pup1970,I ve tried running a single servo ( hi tec 320 oz.torque ) for 1 1/2 years. on sportsman at Houston ( when it was open ) and Dallas.the problem is that the spring inside the servo saver wont hold up under load.it might not be as bad on dirt,but I cant tell you number of nights I spent fighting a tight condition,and all it was is that the spring was giving up and the car would'nt turn.the other ting is that if you do tag something you strip the insert in the saver.I tried everthing ( solid arms plastic and aluminum all different styles ) trust me it won't work.I know there a pain but stick with the dual servos.

I put a longer bolt on the right side (only) of the steering rack on my Pro1 Sprint. It works as a stopper. It hits the servo plate; thus keeping the servo savers from going up and over. That's when they blow apart...

It works great :thumbsup:
