Seanster43 222 Posted July 5, 2020 Hello, I have searched and been unlucky also had a read in the builds section unfortunately gear ratios has always been a total muddle for me. Is there a dummys guide to make it easier 😂. Anyways I plan to run a Superstock Bz motor to the kits standard 79t spur and I was wanting to know what would be best pinion to run for acceleration and likewise what would be better for top end. Cheers Sean Share this post Link to post Share on other sites
Manix92 121 Posted July 15, 2020 @Seanster43 well I initially went with 8.56 on the Super Stock BZ and the motor was getting really hot and so was the ESC. I looked at the manual again for the BZ and it states use within 9:1 - 11.1. So basically I had it over geared, perhaps if you took the foam off that protects the motor from dust you could get away with 8.56 or add extra cooling. Since then I have changed it to the 9.1 specified minimum (or maximum depending how you look at it) and it runs a lot cooler now. Obviously it has lost a bit of top end but compared to something like a silver can it is a absolute missile. Share this post Link to post Share on other sites

Cheers Sean Try 23-22 as a starting point depending on where and how you are driving it. I'm on 23/75 with a 9t sensorless brushless and 2s Lipo. If you look at the set-up sheets on PetitRC you can see some wild gear ration choices, like 25/79 with an 6.5T modified motor. So plenty of scope to dick around. I did try running 18/19 but things were getting too hot from under gearing. Probably wouldn't go much higher with the 9t. Share this post Link to post Share on other sites
