We are in the middle of a blizzard here in Wichita, KS.  So we all left work early, and I brought home a prototype wheel assembly for our ultralight amphibious float.  It needs a slight bit of tuneup, but I figured you'd like to see the engineering work in process.

The wheel used is a 5"; the brake assembly is an Avid BB5.  Assembly is not complete.  Weight of the entire subassembly will be about 7.5 pounds per assembly.

More info on our amphib floats:

We use a special rivet which is designed to be leak resistant.  It looks like this:

Yes, that is a carbon fiber / aluminum wing in the background under assembly.  Here is the partially completed wheel well in the amphibious ultralight float.  A carrythough bracket is visible in the bottom of the wheel well.

Weight is still tracking for 28 pounds per float in straight (no wheel) configuration.

Floats!!! Amphibious Floats!!!

Here's the first photos of our upcoming float offering for ultralight aircraft.

Constructed entirely of aluminum, these floats are designed to work with retractable wheels or as straight floats.

In other words, we're preparing to deliver an amphibious float, and therefore, an amphibious ultralight.  So cool.

The straight version will weigh less than 28 pounds.  (The FAA allows 30 pounds per float in FAR Part 103.)

It will be fun to announce the pricing, and also the full specs.  Here's the photos (the float is upside down...):

Wheel well takes shape.

Front skin is quite riveting.

Some parts still clecoed on.

Computer CNC machining makes for exacting fits.

Strength, lightweight, beauty.  And 7000 series aluminum alloys in critical places.

Easy building for folks who want to do it themselves.

Some of the bulkheads are sold.  Some aren't.

Before the skin goes on.
