OK if I put my car on the track to practice with whatever size tires were on there and make sure its fast enough by OBSERVING other cars and adjusting my gearing as I had previously stated and I beat you in the main I think I proved my point. .... And I will further illustrate Mr Geek squad go get your laptop and go calculate your rollouts..Meanwhile I will be racing and having fun rather then crunching numbers thinking you will get that so called magic gear ratio with so called magic edge. LOL!
Dont make fun of my 5th grade edumacation Im hurt and devastated!!!
Thank you drive thru!!!!!
I love getting you guys going ballistic over the stupidest things its so easy....Thats what makes this country so great remember that

Laughing all the way to the hobby shop and the finish line...BOO YA!!!!!!

btw, good luck. From the sounds of it, you will need it.

Is there a website teaching how to compute roll out?

You can use this following link to a gear ratio program to plug in numbers or ask/PM one of the guys that commented of using a spreadsheet to e-mail it to you.

I have used the rollout method combined with motor temping to reach my goal.

Its well established that there are numerous ways to calculate roll out. For me those PDF files and spread sheets are never where I want them so here's my method. I have a cheapo calculator in my box with the formula "Dx3.14xP/S" written in sharpie across the front. D=tire diameter, 3.14 is Pi, P=pinion and S=spur. tire dia x Pi x pinion teeth divided by spur teeth=roll-out
You can spend all day chasing the right gear ratio as your tires wear or you can just figure it out in this simple manner.
If you are math challenged then just run rubber tire touring car with the masses

And, as someone who doesn't live in your country, I'm not convinced you have the last bit right, either...

This is one of the best explainations I've seen of roll-out yet.

OK I understand how to do the math on roll out but, how do I know what roll out I need? I.E I have worked out my roll out to be 38.24. Where should I aim to be?(in the 40's?) does it depend on the size of the track and how tight it is. I have been told that I should always try to achieve 1-1.

I'd like to know a roll out on a medium size, technical carpet track.
I will run either a 5.5 or a 4.5 Novak motor with 4 cell.
2nd. question:
Are there any other ride height adjusters available besides the one that are
included in the kit? number?
