About us

Grumpy's Hobby started as a fan project in 2022. With the global economy in constant upheaval and shipping fees skyrocketing, Ritewing's founder Chris Klick needed a German partner to streamline the production and logistics for the Drak family.

We will gradually update the site and our product range, exciting stuff is on the horizon.

Please be a little patient with us, we are a small startup and things might take a little in the beginning. As soon as we have streamlined the business, and we are very passionate about aerodynamics, things will be as fast as with any other shop you know.
