Make sure everything fits. Working on Pennys/Nickels, we have less space to work with so just be mindful of that when you’re buying batteries and thinking of how to configure them.
You might want to get grip tape for your Nickel board too, going at those speeds, a little more friction goes a long way.
You definitely don’t need a dual drive configuration.
Get your truck alignment right. You’ll likely have to drill new holes into the Nickel board if you’re using the enertion giant trucks and wheels. You only get one chance to do this! I messed mine up, so turning right is a lot harder than turning left. Don’t make the mistake I did.
