LOL... i jumped the gun yes .. But you defined roll center and then said it wasnt roll center. Thats why you got the coment.

We pretty much just let it hit. Allowing the body to fit loose on the mounts will keep it from doing anything too bad. By loose I mean run the body clips a little above the body so that it can move up and down as needed.

John, Ackerman isn't that hard. Haven't drawn it out in years because we use it as a tuning aid in 12th. That's what the spacers on the servo mount are for.

I am going to buy my 12R5 today and would like to know which servo fits in directly and any recommendations you all have. I am currently looking at a futaba S9650 mini servo

Welcome to 1/12! You might want to get rid of the 96T spur and get 80T and 84T PRS spurs for starters. Depending on which brand of 13.5, track size and other factors, start with a conservative rollout in the low 60's (mm), temp the motor and gear from there.

To be honest many of us are running 88 at the largest for the spur with a 13.5 With anything bigger it can get pretty hard to fit a big enough pinion on the car with smallish tires.

Marcus, do yourself a big favor and get an 84T spur, then you can use a range of pinions of 42 to 46 to maintain a 68-70mm rollout. An 88 will limit you and cause you to replace tires more frequently as they get smaller in diameter.

I'm using the 84 in my R5 with a 13.5 at the rollout mentioned and it works well. Made the A Main today at Jtec.

If you have new tires that are 46mm in diameter and want to use an 88 try a 41T pinion to get a 68mm rollout or a 43T pinion for a 70mm rollout.

hello, I have a 12r5 issue, my rear pod seems to be anything but flat.
first of I have new upper and lower pod plates, new right and left axel plates,and a new football.
the problem is that when I put the motor plates on the bottom pod plate,my bottom pod plate becomes warpred, I hold down the 3 points that attach to the car,and the back of the pod lifts up,so i take the pod apart and all the parts are flat.but when i put them together, the pod seems warped, any body else have or heard of this problem?

Hi,

are your motor plates the same height? Perhaps they tweak the pod plates...

Cheers
