Mile High

This morning, I'd had no hope for flying today.  I called the airport weather line, and it reported that the wind was gusting to 26mph.  In a crosswind, making takeoffs and landings insanely impossible.

Come along with me, I have a story to tell.

I had wanted to fly this plane today:

Yellow Ultralight Aircraft from Belite

So, I went about my work in the shop, and felt badly that I couldn't fly due to the crosswinds.

Afternoon crept around, and another phone call to Jabara weather showed a much more favorable wind:  crosswinds had reduced to 15mph.  Improvement, for sure, but still well above my limit of 7mph crosswind.

Another hour later, and the winds were down to to 8mph.  With the ability of our huge grass runway to angle into the wind, either on takeoff or landing, I was now safe to fly.

====

The gas tank was not full, but I didn't care.  I wasn't planning to fly for more than a few minutes.  I wanted to check out some engine mounts that I'd been experimenting with -- which type would produce the smoothest engine, in conjunction with the new, amazing propeller we'd been trying out?

Last week, I'd tried the new propeller/engine combination for the first time.  On another aircraft, it had produced some fairly eye opening takeoff and climb performance, as documented in this video:  (Click on the picture, and go for a ride!)

(Click on the CAPTION, and the video will load and play....)

Today, I was trying the same propeller/engine combination on the yellow aircraft, along with some slightly different engine mounts.

====

I'm off the ground easily and quickly, and the altimeter has passed 3000 feet in the climb.   (Ground level is 1400, so I'm plus +1600 over the ground...)  I'm kind of amazed that I'm not cold.  I have just my winter leather coat on, a hat, and some good gloves.  Normally, for winter flying, I wear coveralls.  But not today.

====

And now the altimeter has reached 4000 feet above sea level.  The views are beginning to be a bit surreal:  Jabara airport is now a long ways below me to the west; I can see Hawker Beech field to the south, and Benton (Stearman Airport) is just 4 miles to the west.

====

Still climbing; the altimeter passes through 5000 feet.  I no longer am doing anything other than having a good time.  For some reason, the idea of climbing is just a lot of fun.

====

The views are very, very good.  I am able to take off my gloves, and retrieve my phone from my pocket, and take some pictures:

Looking towards the southeast

I keep considering the feel of the engine.  It sounds strong.  I make a note of the squawks to be corrected before customer delivery of the airplane, later this week:

  a)  the control stick is a little right of center in straight flight -- adjust rod end bearing setting to fix
  b)  (maddening)  the EGT/CHT is inop -- must fix!!!
  c)  midrange roughness in engine -- adjust belt tension to ensure no slippage and adjust carburetor mixture
  d)  the floorboard is made from beautiful stained wood (hey, we've always done it that way) but I've decided to change this airplane (and all future airplanes) to aluminum, for safety sake.  The muffler is below the engine and ahead of the floorboard, so putting in a floorboard firewall seems like a good safety idea.  We have some 2024 clad aluminum for this application.
  e)  the brake cable on the left side is skewed.  It needs fixing.
  f)  the radio still does not have the antenna installed, and needs to be tested thereafter.

I think I'm forgetting one squawk, but I wrote them all down and gave them to Gene after the flight.  

====

While the ground winds were 6 knots when I took off, I can tell that the winds aloft at my altitude are very fierce, yet very smooth.  I am pointed into the wind, yet I am hovering in place over my home field.  My ground speed slows to literally 10 knots.  (With a slight bit of work, I could have moved backwards.)  (And this is really no big deal.  I've done this kind of thing before in other aircraft.  I remember hovering over a wheat field many years ago, in a Cessna Cardinal.)

====

The altimeter has reached 5,200 feet ASL.  Just about one mile above sea level.  While I'm nowhere near the maximum ceiling of the aircraft, I'm running out of time, gasoline, and warmth.

I've been higher in a Belite before, but this flight was a little better documented.

Do you remember my old blog post,  What Altitude Did James Reach...?  I certainly flew higher that day.

Time to go down.

One more picture of me ---

Really time to go down.

I push the nose over, and the airspeed indicator shows 70 mph.  (Redline is 80mph.)  I put in a couple of notches of flaps, and it helps reduce the fairly significant elevator forces, as the plane does not want to go down.  Of course, I work in some power reductions.

====

And I land.  Back on the ground.  Gene comments on how I'd been a hovering spec in the sky.

====

I've been recording the flight on GPS Essentials, on my DroidX phone:


The proof is in the flight profile.  Climb to 5200 feet; ground speeds below 10mph (and nearly 100mph); turning into the wind and with the wind.  Climbing at a steady rate of about 180fpm. 

(looks like someone made a move in Words with Friends)

Thanks for sharing this flight with me.

World Class Takeoff and Climb

Our Belite ultralight aircraft is now demonstrating world class takeoff and climb performance.

This is our new aluminum airplane design.  The propeller / engine combination has been tweaked for optimum performance and smoothness.

We've got some great new video which proves it ---

You can see the video here.

(Thanks to friend Jim Loewen for providing the video.)

Gorgeous Skies; First Flight; Video

Hey Everyone,

Please remember to follow me on Twitter.  @jamespwiebe  I'll be twittering from Sun N Fun and Oshkosh later this year.

It was a gorgeous afternoon in Wichita, KS -- temperatures in the low 50's, calm winds, blue skies.

I was scheduled for a first flight in a new airplane.  I've done this a fair number of times, and it is always a process which is cautiously approached and ultimately thrilling.

This particular plane is equipped with a 45HP MZ-201 engine.  I ended up flying it with a couple different propellers (none of which was quite right) and I look forward to flying the plane the correct prop later this week.

But this flight was still pretty cool.  I attached a high definition portable camera to the wing, and took video of the flights.  You can see one of the videos here on Belite's YouTube channel.

Gene captured some great pics of the maiden flights -- and a couple of them are just spectacular.

The new owner is in California.  We look forward to shipping this plane in a few days.

You might enjoy reading the following details:

1)  The windshield still has the plastic film in place.  We pulled it away only on the left side of windshield, and held it in place with tape.  I couldn't see out the entire windshield.

2)  The fuselage frame is a welded version of our new aluminum framework.  The entire frame is constructed from aluminum.  The wings utilize carbon fiber spars (which you can't see in the picture.)

3)  The paint is just UV resistant primer from Stewart Systems.  We expect the customer to finish covering and painting the airplane, but it's up to him.

4)  The engine is a 45HP MZ-201 from Compact Radial Engines.

5)  First flight was just smooth and easy.

6)  You can see the camera (from GoPro) mounted under one of the wings. 

7)  This aircraft has the big 5x5 tires.  Note the white tire labels are still on.

Top 12 Things you can see in test flight video of ultralight aircraft

Here is what you'll see, in this YouTube video of Belite's ultralight airplane:

10.  I turn to the camera and smile a lot.

9.  I do mild wingovers.

8.  I do steep turns around a point.

7.  I enjoy the beautiful weather on December 29, 2011.

6.  I get to prove that flying is more fun than working.

5.  I make the owner of this airplane wonder why I haven't delivered it already.

4.  I do a really sweet full stall 3 point landing.  If you look very, very carefully, you can see the steel landing gear springs barely compress, but just for a moment.

3.  You can see what a poor video editor I am.  Actually, I didn't do any editing ... just loaded the video to YouTube.

2.  At the end, you can see Mike, Gene, and my nephew, Matt.

1.  You can see the plane climb from ground level to 800' AGL in a little over two miles of ground distance.

0.  You can see me dive the plane to over 80 mph (IAS)

-1.  You can see why I enjoy doing this.
