his board which has the idler on the bottom.

We intentionally placed the idler on the “wrong” side. It’s more of a preferred side to be fair, and we had good reasons. First, the Aero Pro is a street board using street wheels, placing the idler on the driving side will make it easier for clearing the debris. Second, the Aero Pro isn’t 200A/side, we have only 20/25Amps running per motor and it’s not a lot of load. And lastly, the drivetrain on the Aero Pro was designed to decouple the motor and the wheel, in order to improve coasting.

It sounds like an unusual design choice.

Have I been doing it wrong?

No, if anything parsec is doing it “wrong”

With the idler on the top-side, the loose belt is more likely to be damaged by the road and might even cause a safety risk when it gets caught on something.

The aero pro seems to value it’s “longboard feel” as a high priority, part of that feeling is being able to free roll like a longboard, which requires really loose belts, having belts that loose leaves them at a greater risk of damage without the belt being pulled away from the ground by the idler.
