Here's what to check to figure out if your Stoke is Series 1 or Series 2:

• Remote: If you use an R2 remote, it’s likely Series 1. If it’s a Phaze remote, likely Series 2.
• Motor controller: Series 2 usually has a distinctive striped "E" logo on the controller under the board. Whereas the Series 1 is a smooth plastic around the E logo.
• If you’re still unsure, reply with a photo of the underside of your board (especially near the battery and motor controller) and I’ll help confirm the model.
