Just some quick notes...

I'm heading off to Alaska tomorrow for some R&R, so I'm doing some quick posting today with some detail on our aluminum taildragger, along with some photos from a new airplane.  On this particular airplane, I've modified the fuselage to use trusses instead of fabric; we're adding some more gussets as well.  Hopefully this will give our builders some ideas.

Rear Fuselage of Belite Taildragger.  Also note custom wiring circuit for use with strobe on tail.

And we've changed our heel and rudder pedals so that they are user assembled.  Here's a detail photo, also showing the shopbot cut floor pan they fit in, complete with nylon bearings:

Here's some more pics of the gorgeous yellow plane we're getting set to deliver:

Short & sweet:  Quick video showing Belite UltraCub ultralight airplane flyover:  (Click Here)

This plane has already been deliverered.  Got some awesome video of this plane in flight, which will be posted very soon.

Dusk skies, velvet touches, calming winds, drought in Kansas.  Heat.  Cooler up higher.  Beautiful evening to get up and look around.

An evening to explore.  What is the earth saying tonight?

The field two miles to the east responded to the drought by having itself cut.

Truck, combine, farming.  Responding to the drought by cutting the corn.

Ultra Lightweight Instrument Panel

I thought you might like to see the back of the instrument panel.  I also thought you might like to get some insight as to how the instrument panel is wired up, so let's do it.

The instrument panel in my aircraft is assembled from very lightweight Belite instruments.  My instruments provide information which is essential for flight in an inexpensive and easy to read manner.  As I was flying earlier tonight, I took another photo of the instruments inflight:

Belite Instrument Panel in flight

Kewl.  I like 'em.

The panel is designed to quickly be removed, so I can fly with minimal instrumentation when I want to.  (The blank hole on the left main panel is for an EGT/CHT, which will be added.  It's the only instrument I need when I pull the main panel.)

Earlier today, I took a picture of the back of the exact same instrument panel, and there definitely is some electronic magic going on in the wiring:

Some notes:

1.  The top right module is a +12V regulator.  I use it to regulate the raw voltage from the main system/starter battery.   (I use an extremely lightweight lithium polymer 14.4v battery for the starter, which is a little hot to use with the instruments.  When fully charged, the lithium polymer battery reaches over 16.0 volts.)

2.  A potentiometer is used to control instrument dimming.  It's in the lower right corner, immediately below the power regulator.  One side is connected to +12V, the other to ground.  The wiper (middle) output of the potentiometer connects to all the instruments to provide dimming level input.  The dimmer worked really sweetly when I was flying in dusk conditions earlier tonight.  More on that in another post.

3.  Not shown is an inline fuse, 1A, which is connected to the power regulator input.

4.  YES, that is a steam gauge air speed indicator in the lower middle.  I don't have one in stock right now, so I used an old fashioned steam gauge.

5.  The shrink wrapped modules are either electronic altitude (pressure) sensors or VSI sensors.

6.  That's a voltmeter at the top.  It's only connected to show regulated voltage (around 12v) but I might add a switch to allow selection between unregulated and regulated voltage.  A hole is already drilled for the switch.

7.  All the instruments have their power wired from a common avionics power switch (lower right side of panel), along with a common ground.  Just switched power, ground, and dimming to each instrument.

I put it all on a scale, and the weight is 1 pound and a fraction of ounce.
