SRB Running Advice

[Gregor]

Ok, not sure if this was covered before?

But, I finally had a weekend that I could sit down and build a Superchamp runner. I will be honest, I have put many SRB's together and maybe on a few occassions actually ran the thing (Not very often!). I just enjoy painting them and putting them together.

So I put this (Will be a copy of Bimmermans SS) together and got a modern ESC, and wired the thing together and made a holder for a normal batt pack. Lined up the front suspension and tie rods.   Put some older tires on and took it outside.

It cranked the throttle and took a nice blast down the ashfault driveway and guess what... It turns but keeps going straight. The motor must be still rather good, because I can do wheeles down the drive way?  Anyways, it will not turn on full throttle.  Is this a case where they are all like this?  Or have I messed up the front suspension some how.  It looks like the parts are straight in the front. The only thing that I can find strange is that the one wheel is not turning all the way.  Should there be more toe in or out?

Hope someone can help me make it turn!

Well you will get a few replies on this one...The SRB's are back heavy and do not have a factory diff..They like to go forward...You will notice they turn pretty good in reverse..lol..Anyway I have been working on a brushless sysem thats very powerfull..Here is what I have found so far...If you can aquire a rear diff that will help..but I have found the best thing is the extended front end...CRP made one that is 1/2 inch wider than stock..between the two the car will turn well..but finding the parts is another story...regards jerry

I'm running my scorcher with some toe out, allthough i've got a direct steering setup with a kamtec radio box.

Watch the wheels as you steer. turning left for example, the left hand wheel will want to take a tighter turn than the right hand wheel, which will take a wider arc to get around the same turn. this means, the left hand wheel will need to be turned more by the steering rods than the right hand wheel. for a right turn, the opposite will apply.

if your steering gives you the opposite affect, the turning circle will be rubish - as one wheel will be pushed and one will be dragged into the turn!

hope this helps a bit []

Thanks for the advice!  it would be nice if someone could take some top shots and we could see that! It sounds like I have a case where the one wheel  Turning left (Left side) is as far as possible, but the right wheel is only 1/4 turned.  If this makes sense?
