More Info: Ultralight Aircraft Aluminum Fuselage

The #2 Aluminum rear fuselage is taking shape nicely.  This particular aircraft is destined to be a tricycle gear airplane.

Everything you see here is weighing in at about 33 pounds, including tricycle mods.  I am pleased.  We had taken a 'weight bump' but have gotten some of the weight back out by trimming excess off cross members.

We're waiting to mate this fuselage with carbon fiber spar wings; we're currently out of stock on the carbon fiber and waiting for a shipment to come in.  As a result, the fuselage will not be flying until around Thanksgiving.  It is scheduled to deliver to a customer in December.

Please note the gas tank / cargo compartment.  It's designed to hold a 5 gallon plastic tank, for easy swapping.

The purpose of the side aluminum sheet panels is to spread landing gear loads from the gear into the fuselage.

It would be very easy to 'metalize' this entire airplane.  I hope some customer chooses to do that.

Phenomenal Performance from Yellow Aluminum Ultralight

You'll get three things from this post:

a)  I can't stop glowing over the phenomenal experience I had flying our aluminum prototype airplane.  It was configured with a 28HP engine and the performance was very close to what we've experienced with our 50HP airplanes.  The reasons why this all worked:  light aluminum construction, a big wing with an awesome low speed coefficient of lift, (bigger span, bigger chord), bigger flaperons, and the exact right prop/engine combination.  I took a GPS chart on my phone of the flight and will try and figure out how to post it.

b)  I can't stop glowing over the phenomenal experience I had while practicing off-field landings in the next door hay field -- my able assistant Gene captured the STOL landing to perfection.  I cranked in two notches of flaps and nailed the touchdown spot within 15 feet.  After rolling to a stop (and I didn't use maximum braking), position was noted. Gene and I went and measured the touchdown roll with our tape -- 100.5 feet (that's 100 and one-half foot) from touchdown to stop.  The landing was made full stall (and was nearly full STOL, for those that grok the difference) and the plane dumped onto the hay from about a foot or two off the ground.  The steel spring gear just absorbed it all, you can see the tailwheel disappear into the grass in one of the pics that Gene took, and nuthin' bent.  Just saying.    Oh My what fun ------ Steve you will like your plane.

c)  The plane is really pretty.

That's three things.  Here's picture proof.  Let's start off with three pictures of the plane just flying around.

Now let's look at that landing sequence, showing short final into the hay field with the 100 foot stop:

Already stopped!!!  Turning

Yeah Gene, I did it.  :-)  Nothing broke.

Pretty Plane, Awesome Performance, I like it...

Service Bulletin 8-24: Rod End Bearing needs cap washers

We had a partial failure on a rod end bearing, on a lift strut.  The point of failure is where the lift struts attach to the fuselage.  The internal structure of the rod end bearing began to fail, and as a result, the rod end bearing might have slipped over the head of the bolt.   If this had happened, there is a strong possibility that the lift strut might have detached from the bearing bolt on the fuselage, with damaging or catastrophic results.  A simple solution is the addition of a cap washer.  We recommend immediately adding these washers to your aircraft before further flight.  It is important that the top washer is trimmed so that it does not hit or rub the lift strut.

In order to prevent these rod end bearings from slipping over the head of the bolt, we are installing cap washers:

Here is a photo of the reassembled lift strut attach point, showing the rod end bearings and the cap washers.:

The bolt has been reinstalled, complete with quik release key (safety wire is of course also acceptable).

If you need these washers, please contact us and we will supply them at no charge.

The integrity of the rod end bearings should be inspected with each preflight.
