A Message from Mr. Tiny Whoop

about Tariffs and Pricing

Hey everyone,

I’m speaking to you now both as a business owner and a member of the FPV family we've built together.

For almost ten years now, I’ve been doing everything I can to keep Tiny Whoop prices steady, even as costs started to rise. But with the newest wave of tariffs—more than doubling the cost of nearly every part we import from China—that fight has hit a wall.

Lots of you have already noticed some prices going up across the site. This isn’t a price hike to chase profit. It’s survival mode. Like everyone in the FPV industry right now, I’m facing a set of changes that hit fast and hard. Nearly everything we source from China now costs us more than double.

For an irresponsibly long time I ate the costs of the tariffs, but the math doesn’t work anymore without putting Tiny Whoop at serious risk.

So here’s what I want you to know:
Every price increase is a response to real, unavoidable costs.
Even with the price increases I’m taking a big hit.
When this pressure eases, I’ll roll back prices immediately.

If you have any questions or ideas it would mean a lot to hear from you!

We’re still shipping every day, still guaranteeing satisfaction on all orders. But this is the toughest moment Tiny Whoop has faced in nearly a decade.

Through all of this, my mission hasn’t changed. I’m still committed to helping people experience the gift of flight, to keeping TinyWhoop.com on the leading edge of innovation, and to making sure the magic of Tiny Whoop doesn’t get swallowed up by politics and global economics.

If you’ve been a part of this ride in any way, I am so, so grateful! Thank you for supporting Tiny Whoop, thank you for supporting my family, and thank you for being a part of this amazing community!
