SERVAL 5-inch racing frame

The winner is thinner

Most frames keep the same thickness along the whole arm. The Serval 2.5's tapered arm is both tougher and lighter.

I ran simulations on 15 different arm shapes, and one of the lightest turned out to be the strongest. Hard to believe, right? I validated it in the lab and turns out, it’s true.

Practical and easy to build

The Serval’s wide top plate protects your VTX from costly midair hits. It has plenty of space to build. You can use a capacitor and even a stack saver.

And yet, a full Serval build with battery is only ~1% heavier than a MS25, Zigzag or LightSwitch Ultra.

Fully open source

The best way to buy a Serval is from the Tressym Shop (here), but you can also cut your own.

Modify it, remix it, even sell it if you want - just link back to this page!

This also guarantees fair prices everywhere, forever.
