Optima Mid Custom Special- your help please
 

It's time I got this car out on to the race track for some vintage racing. It's been more than 3 years since I have done any racing and I am rusty to say the least.

I'm looking for some assistance from anyone knowledgably with Optima Mids and gearing to be honest.

The Car.
When I built this thing car I added ball diffs, a hardened after market idler and an aftermarket spur hub and TUFNOL spur gear. I opted to go with Yokomo alloy wheel adapters to accommodate JC Racing 2.2" rims and modern day rubber. I will most likely stay with 'HoleShot' tyres or the like.

The Track.
tracks I will be driving on are primarily dirt/clay. From what I know the surface is usually a little loose but I will need to confirm this in the coming months.

Ok with this in mind I want to run a brushed motor. I have a 14 turn Double wind OZcharge motor that works well. It's been skimmed and runs efficiently. ESC wise I have a TEKIN FX Pro and batteries are 4200 Lipo saddles.

I am no expert with roll out and gear ratios (or even motor temps for that matter) so this is where you guys come in. From what I have heard the car has an internal gear ratio of 2.64:1 and the car has a 48dp 87 tooth spur gear. Pinion is currently a 20 tooth for starters.

With your suggestions I will purchase some B4 spur gears so I can fit the custom slipper layshaft my friend Jake (Seabass on 10TALK) sent me.
Here's a pic of Jake's-

Please feel free to post any suggestions or comments that you think will contribute to this car's rebirth onto the race track.

Is this going to be raced against my mid soon mate?

You know Dan, I did have it in mind :thumbsup:. Would be good if I could offer you some kind of competition. :D
