Mike- good to see you again. question, is the chassis that was run at the worlds (asphalt 2.5mm?) would you run the same chassis on carpet? if not what would you run? I have the crc car and I am testing a prototype car for someone else. But thinking about getting the 5r lol. Let me know what you think. also do you always run the servo in the low position?

Sean is right..... Thanks sean..



rx7ttlm .. I run the out of the box chassis on carpet.. not sure what they ran at the worlds, But i think it was the stock one .

as for the servo . Do you mean flat vs up or low on the servo saver ??

I will answer them both lol...

I run the servo flat always. Back in the day i had a massive hard time getting a car to turn into the corner and putting the servo flat on the chassis and creating a little bump in on the bump steer caused the car to get aggressive going into the corner so i kept it and always have had it since..

as for the servo saver... I run a mid kimbrough one in the lowest holes. I liked the ackerman that it gave me and this is more of a driver preference like the bump steer thing also...

what are y'all running for gearing on a 17.5 stock BL motor? Do you need to purchase a different spur other than the kit one?

Default gear

74 spur and range from 40-52 pinions, but either way you need a small spur, 81 at least

Well If you know how to figure out Roll Out ...
Start with about 75mm or 3 inches per motor revolution.

Those are too big. You want a mini servo.

Hello, I am new to the 1/12 scene and just picked up a 12R5..I have a few questions.

I plan on using a Futaba 9650 steering servo but came across some posts about the stock servo saver not fitting..Which servo saver should I purchase that will fit the 9650....

I am not sure if I am going to run brushless or brushed..What would be the best set-up for a medium size track..I am leaning towards a novak 4-cell brushless setup..What would be the best gearing to start with. and it looks like I would also need to pick up the optional parts from AE to run a brushless setup......

Where can I purchase 64pitch spurs as I cant seem to find too many sizes on Tower or horizon..

I am running Jaco tires,,,Would would be the best tire setup for a medium size carpet track..

That should do it for now..If there is anything else I should now while building and setting up up the car please let me know..I am trying to do a lot of research as well..Any help is greatly appreciated..Thanks...

JP116,

You should buy a Kimbrough small servo saver for Futaba servos, they are white in color. You can also buy the Kimbrough Medium servo saver I believe, most people run the small sizes though.

You don't need to buy the optional stuff to run brushless motors, they came out with it so that the car was optimized for brushless, meaning the motor was centered. If your just getting going you can buy that stuff at a later time if you need to.

After messing around with the charts and understanding rollout I think I have found my gearing starting point..With the Novak 10.5 motor according to the site I would like a rollout of 53mm/Rev..To achieve that with the 96T spur I would be in between a 34t-40T pinions depending on tire wear...Let me know what you guys think..Thanks...

you maybe a little low on the gearing. Last time I ran 10.5 I was in the 60-61mm range
