So now that you have lots of power, you realize you have a new issue. You need to control the speed. There are a lot of controllers out there, and the ones that most other racers choose, are the ones made by Parma. They've been around since the sixties. Parma's quality has always been great. First, the way they fit in your hand, it's perfect. Super smooth trigger action, and a lot of power selection in ohms available. The lower the number of ohms gives less resistance and the speed comes quickly. High ohm controllers are great for low speed and even cruising. So they are perfect for a casual stroll through a highly landscaped track setup. Here is a great selection of controllers including favorites from Parma.
