Vacation (5/14/11-5/22/11)

I haven’t been building much over the last couple weeks, but I have a good excuse…vacation.  Between getting ready for vacation, going on vacation, and recovering from vacation, I haven’t been able to squeeze working on the airplane into the schedule.

For vacation, we decided to go on a cruise.  This is the first time either one of us has been on a cruise (Amber served in the Navy, but those cruises don’t really count as time aboard a “fun ship”), and I highly recommend it to anyone considering it for their next vacation.  The best part of the cruise is that it is almost all-inclusive (the exception being alcohol and soda) and you don’t have to worry about anything…your food, lodging and travel are all taken care of.   On this trip, we sailed roundtrip out of Galveston, TX, with stops in Mexico at Progreso and Cozumel.

Our ship...the Carnival Ecstasy.

In Progreso, we took a bus trip to go see the Mayan ruins at Chichen Itza.  The ruins are impressive, but the weather was miserable.  The heat and humidity here made walking around the city a real effort.

In Cozumel, we took a boat to Isla Pasion and spent a few hours at the beach.  While at Isla Pasion, I also asked Amber to marry me and she said yes.  So, I’ll be adopting her two dogs, and she’ll be adopting an airplane project…seems fair to me!

Arriving in Cozumel.

She didn't want the traditional diamond solitaire, so we went with something a little different.

Airplane construction will resume shortly!

Tailwheel Endorsed (1/21/11-1/22/11)

No building this weekend.  However, there was a lot of aviation activity as  I spent all day Friday and Saturday flying a Super Cub!  At the end of the day on Saturday, I walked away with a fresh tailwheel endorsement in my logbook after a total of 7.3 hours of tailwheel time.

This is the Super Cub that I used for my tailwheel training. With those tundra tires, there's a lot of fun stuff you can do in this plane.

Not exactly high tech...the Super Cub's panel only has the basics.

I have to admit, I was nervous about flying a tailwheel airplane.  I was actually nervous about flying in general since I haven’t been flying much the last two years.  However, after a few minutes in the plane, I was starting to feel comfortable again.  

Due to the limited availability of tailwheel aircraft for instruction, I opted to use Promark Aviation Services in Burnet, TX (approximately 2 hours north of San Antonio).  We started on Friday morning, took off from Burnet, and flew towards Lake Buchanan and Llano.  Before crossing the lake, we turned north and headed for a section of the Colorado River.  When the river came into view, we dropped into the canyon and slowly flew along the river.  For basic air work, following the river sure beat doing S-turns over a road.

After following the river for a bit, we turned towards Llano and started doing landing after landing on their grass strip.  All of these landings were 3-pointers, and, after about an hour of pattern work, we taxied to the ramp and went inside for a cup of coffee.  After the break, we were back at it, but this time we worked on forced landings and engine out procedures.  This went on for another hour before we headed back to Burnet.

Once at Burnet, we made several landings on the grass between the runway and taxiway.  Then, we took another break for lunch. 

With full stomachs, the instructor and I headed back to the Super Cub and flew the pattern at Burnet.  This time we did a couple three pointers in the grass and then transitioned to the paved runway for some wheel landings.  Surprisingly, I enjoyed the wheel landings.   Searching for the ground in a two-point attitude seemed more comfortable to me than flaring and waiting for the ground.  However, landing on the mains, keeping the tail up with forward stick pressure, then pulling back to lower the tail when I could no longer keep the nose up, was challenging to coordinate.  Not to mention that I had to constantly steer with my feet throughout the whole process!

After a few of these, we taxied in and called it a day. 

On Saturday, we returned to Llano for some more work on their turf runway.  We started with three pointers, then some wheel landings were thrown in.  Also in the mix was some more emergency landings and some slips to land.  After an hour or so, we again taxied in for a short break.

After the break, the real fun began.  First, we headed into the hills, searching for small strip that basically amounted to nothing more than a clearing in a cattle pasture.  From the air, this strip seemed really short.  However, after landing, it turned out we needed less than half of it.  We did three landings on this strip and then headed back towards Burnet.

On the way to Burnet, we crossed Lake Buchanan and turned towards a small island for some off-field landings.  The landing area here isn’t really a runway or strip.  There is only a trail that has been created through repetitive landings.  The instructor did the first landing on the island in order to show me the best touchdown point and also demonstrate how you have to make a slight right turn immediately upon takeoff in order to avoid some trees at the end of the island.  Once we were in the air, the controls were handed back to me so that I could take a shot.  The first landing was ok, but bumpy.  The second approach was high and I opted to go around.  The third approach resulted in a great landing!

Finally, we headed back to Burnet where I made another landing in the turf between the runway and taxiway.  As I slowed the plane and turned onto the taxiway, the instructor told me to taxi to parking because we were done.  I was surprised that we were done so soon, but he assured me that I did a great job and was tailwheel capable!

Overall, I learned that tailwheel aircraft shouldn’t be considered scary or dangerous.  However, you do need to keep focus and use proper technique.  I now understand what it means when people say you have to continue flying a tailwheel airplane until the wheels are stopped.  I also think that I have finally figured out what those two pedals connected to the rudder are for.  In a tailwheel, constant rudder input and adjustments is a must.  As for whether or not I’m going to build my RV as a tailwheel or nosewheel…let’s just say that the title of this website, Ethan’s RV-7A, may need to have a single letter removed.

Burnet CAF Museum

I noticed there was a small CAF museum near the FBO at the Burnet airport. After my Super Cub flight, I decided to quickly stop there before heading back to San Antonio.

Inside, the museum had a small display of WWII uniforms, weapons, documents, etc. The displays were interesting, but that was only a small part of the museum. Outside, there were several planes that you could walk around, with the highlight being a DC-3 that had the door open and a staircase inviting you to climb aboard.

The Bluebonnet Belle is a polished aluminum DC-3 that I’ve seen at several air shows. Today, the CAF members were conducting her annual inspection, but they were still letting people walk around and inside the plane.  The airplane was gorgeous, inside and out.  The interior was either all original or restored to look that way.  There were several rows of seats and also a couple of stretchers/cots that would have been used to transport wounded soldiers.  The outside was beautifully polished…not a fingerprint on her.

The Bluebonnet Belle. The CAF was conducting the planes annual inspection while I was at the museum. I was told that last year's annual took a year and a half to complete due to several problems being found.

I took this picture so that I would have the SN and tail number of the DC-3. However, I thought it looked cool because my reflection showed up in each of the rivet heads.

Another of my "artistic" shots of the DC-3.

Other planes at the museum included a very nice SNJ and PT-19 as well as several other miscellaneous vintage aircraft.  While not a large museum, it’s definitely worth a look if you are in Burnet.

Where To Put The Third Wheel (11/27/10)

Wait...the third wheel is in the wrong place!

I’m getting close to placing an order for my fuselage kit.  Throughout the entire planning/building process, I’ve been planning on building an “A” model (nosewheel or tricycle gear).  However, I’ve recently started thinking about building a tailwheel model instead (standard gear).  There are a few reasons for my nose gear doubts:

  1. Van designed the plane with a tailwheel.  The tricycle gear model came out later.  If the plane was designed to be a tailwheel plane, why mess with that design.
  2. The nose gear, even though it has been redesigned, still looks weak.  There is still the occasional report about it failing after hitting only a small bump or digging into a hole.  The new gear design seems to have fixed many of these problems, but it is still happening occasionally.
  3. Related to number 2, the tailwheel allows you to land on many more “unimproved” runways than the nosegear would allow.  Tailwheel aircraft are just better at landing on grass, gravel, etc.

Of course, the tailwheel also has its problems, with my main concerns being ground loops and prop strikes.  In order to see if my concerns were legitamate, and to get some flying in, I scheduled a tailwheel intro flight in a PA-18 Super Cub based out of ProMark Aviation Services in Burnet, TX (KBMQ).  When I arrived at the FBO, I sat down with the CFI, Ken Wittekiend, and we talked about my concerns, and tailwheel flying in general, for about an hour before heading out to the Super Cub.  The main points of the discussion were that ground loops aren’t a problem if you use good technique and keep the plane straight at all times, and prop strikes are unlikely except during heavy braking…as I later found out, you really have to push the stick forward hard to get the tailwheel off the ground during the takeoff roll and the nose doesn’t want to dip much lower than level attitude when the stick is forward.

As soon as we took off from Burnet, the controls were handed over to me.  I had not flown for close to 2 years, so I immediately did a little over controlling and mild wing rocking…I’ll blame it on flying an airplane with a stick for the first time.  However, I quickly returned to level flight, gained some altitude, and then did a few turns to get used to the airplane.  After some slow-flight and a few, incredibly mild, power-off stalls, we turned towards Llano, TX (KAQO), where they have a very wide grass strip.

First, we did a low approach, where I just tried to keep the airplane close to the runway and straight.  The CFI handled the throttle so all I had to think about was keeping the nose up.  Then, we went around and started over.  This time, we actually landed, and I was very surprised how much rudder input was needed to keep the plane straight (good thing that was a very wide runway).  We did two more landings, with each one getting a little better.

Finally, we headed back to Burnet.  The Super Cub isn’t the fastest airplane, but it was fun to do some low and slow sight seeing from about 500 feet.  I’ve never actually had to climb to get to pattern altitude, but as we approached Burnet, I did just that.  We made the final landing, parked the plane, and talked a bit more about getting an endorsement.  I’ll likely finish the endorsement as I decide how to build my airplane.  However, I don’t know that the tailwheel fears are justified.  If anything, having to use the rudder more makes you a better pilot and I now realize how much a tricycle gear airplane, like a Cessna 172, lets you get away with.

The mains are huge! Too bad the door isn't a bit bigger, at 6'2", this was not an easy plane for me to get in and out of.

Lackland Airfest 2010

No building today, but only because San Antonio’s annual airshow is this weekend.  With a line-up full of great demos and performances including Tora Tora Tora, the Aeroshell Team and the USAF Thunderbirds, this year’s show was a must see.  My Dad and I spent the entire day at the airshow.  Despite my sunburn, it was definitely worth it.  A few of the highlights and pictures:

Rv-4 – It seemed a little out of place at this show, but a lonely RV-4 landed right before the demos started.  At least it keeps this post RV related!

A RV-4 even showed up and landed right before the demo flights started.

Tora Tora Tora – Although I had seen this demonstration several times before, and it can get a little long and repetitive, I was surprised to see a new edition…FiFi!  FiFi is the world’s only flying B-29 Superfortress.  She was recently restored and flew a couple of months ago for the first time since 2004.  After making her first flight, she had some engine problems that needed work, and I hadn’t heard that she was back in the air again.  Seeing this plane parked on the ramp was a nice surprise…seeing it fly in the Tora Tora Tora demo was very unexpected.

After hearing so much about FiFi, I was surprised to see her fly in the CAF's "Tora Tora Tora" performance.

F-22 – I think this is one of the coolest planes ever!  The maneuverability it demonstrated is amazing.  I only wish they would park it on the ramp, instead of the taxiway, so we could get a little closer.

Just sitting on the ground, the F-22 still looks amazing!

Aeroshell Team – I had never seen the Aeroshell Team perform before, at least not in person.  While they don’t have the speed or power of the jet teams, they gave a very graceful formation demonstration using the SNJ (a.k.a…T-6 or the “pilot maker”).

The Aeroshell team warming up the engines of their SNJs (T-6) before putting on a gracefull formation demo.

USAF Thunderbirds - The Thunderbirds capped off the show.  While I had seen them perform at several other airshows, jet team performances never get old!  The head-on passes from the two soloists are simply amazing, and I just don’t understand how the formation group can stay that tight while going that fast!  Wrapping up their performance, they did a maneuver where all of the jets approached show center from different directions at speeds nearing mach 1.  If anyone is off…!

The USAF Thunderbirds capped off the show!

A Different Kind of Homebuilt (1/26/10)

No work on the RV last night or tonight.  However, I did do some homebuilding.  Instead of working on the plane, I built a computer for my girlfriend.

Building computers is intimidating to many, but it is surprisingly easy.  Her’s has an Intel Core 2 Duo processor and ASUS motherboard for brains.  Also, 4GB of dual channel RAM, a pretty decent graphics card, 580GB of hard disk space, DVD burner, a 24″ monitor, and Windows 7 for the OS.  All this for under $1000.

If anyone wants a custom computer, contact me.  I work cheap!

Pretty nice setup for under $1000 (including the 24" monitor).

A nice, quiet, cool case.

The guts...Intel Core 2 Duo processor, Asus motherboard, 4GB DDR3 dual channel RAM, blah, blah, blah.
