Hot Bodies Cyclone12
#168
A description and charts for this can be found at http://www.carsrcracing.co.uk/?page_id=33. The charts are done in millimetres per rev though rather than inches.
I've not run a 13.5 myself (UK rules are 10.5), but from what I've heard use a 78 tooth spur and aim for a starting rollout of around 68mmpr.

Anyone fit a KO 949 servo in their C12 using the 1 piece mount? I shimmed it forward 2mm using spacers but wondering how much this will effect steering/ackerman? Looking at some of the pics in here I see people shimming their servo saver forward so maybe it is the same theory. Just curious if anyone has any feedback.

If 12X arms are used it isn't possible to move forwards quite as much, or the turnbuckles will catch. Again for a 9650 1.5-2mm is the max.

I've been told that the HB hard spring is just slightly softer than an .020 Associated, so that could be a starting point for comparison.

Not used the alloy mount, but moving the servo forwards does affect ackerman. The optimal servo saver shimming (i.e. maximum ackerman) using standard mount and servo saver for a Futaba S9650 is 2.5mm. Any more and it starts losing it again. Hard to say for other servos due to size differences, but it sounds like moving it 2mm forwards will actually make it better rather than worse, though trying it out is always the best test.

Most of the guys around here are running 60-65mm rollout on a 4 cell 13.5 car. I start a set of tires at 44.5mm in the back, so for me, 37/84 would get me in the ballpark and shouldn't be an issue fitting in the pod. 39/88 would get me there, but I might start getting close to running out of room at the front of the pod. Maybe go a tooth or two down on the pinion for the first run and keep an eye on temps, then go up looking for better lap times until the lap times stop getting better, or the motor starts looking hot... Temperature probably won't be an issue on a big medium grip track, but better safe than sorry...

twitchy subject
Hello,
I have both the C12 and the C12X. I have been running 1/12th scale for a few years now. I know that 1/12th scale cars tend to be very twitchy. Both the cars are built pretty much stock. The car runs great but I think I can drive the car alot hard if I can figure out a way to take some of the twitchy out. I read that the front brace is supposed to give the car more steering. Is that true? I thought it would be the opposite. I have dialed the dual rate in my radial down to almost 50%. That has been the only way I am able to drive the car. I am very happy with both cars just looking for a little more. Any suggestions or help would be appreciated. THX!

Tire selection is usually the first thing to figure out, see what others are running. Your dual rate at 50% is fine, sometimes you have to make chages to the rear in order to affect the front.
