Spotted For Sale: 100HP Clip Wing CUBy Homebuilt - Wish I Could!

A beautiful Clip Wing CUBy homebuilt spotted for sale on Barnstormers.com

(click the pic to see the listing)

 It's true, my heart rate might increase more than yours at the sight of this gorgeous looking Clip Wing CUBy, but c'mon, what could be more fun than sweet 100 hp taildragger that can fly all day with the door open and costs less than half of a Cessna Skycatcher? Yeah I know, the Skycatcher would be new, and this is a used homebuilt. Whatever. This thing is awesome! If I had some bucks in the bank or a credit score that wasn't in a flat spin, I'd be hopping in the car right now to go check this little gem out. Ultimately, in my opinion, it's the clipped wings that really make this airplane special... more on that in a minute.

 

 If you check out the listing for this airplane you'll see it called a 'Cubby', but to be accurate it's really a CUBy, by Wag-Aero. It's pretty interesting that Dick Wagner was on the cutting edge way back in 1975 when he introduced the homebuilt Cub clone that he named CUBy. There's quite a bit of story that goes with all the CUBy development, and hopefully one of these days I'll research it up and post the details. But for now it's good to note that while the Cub clone frenzy has been booming in the last dozen years or so, it really had its beginning with Dick Wagner and the CUBy back in the 70's.

 But the real story here to me, is in this next picture!

Everybody's Doing The Electric Cricket!

Hugues Duval in a Cri Cri aircraft powered by two 35 hp Electravia electric motors

  Ok, maybe not 'everybody', but first it was Aerospace giant EADS building the little 4-motor electric Cri Cri and then right on their heels was this one pictured here that uses two 35 hp electric motors from Electravia. Both actually had their first flights back in September. Kinda interesting that one of the smallest airplanes in the world has already been so successful at demonstrating the flight potential of electric power systems.

BTW, when the 'Cri Cri' first appeared from French designer Michel Colomban in 1973, the name Cri Cri was also known to be interchangeable with 'Cricket'. I wasn't able to confirm exactly how the two words are connected (I've seen several different stories) but regardless of which name you use, you're talking about one of the most unique aircraft ever designed and built. I can still remember the unbelievable sight of two Crickets doing some pretty hardcore low-level aerobatics at Oshkosh in 1981... still one of the most impressive aerial displays I've even seen!

 The real story here however is the electric propulsion systems. We're seeing several innovative ideas pop up around the world showing the potential of electric power for flight, but there's something extra encouraging to me to see this very familiar airframe so effectively adapted to it. It's almost getting easy to imagine that before long we'll see amazingly affordable and effective 'sport flying' machines readily available. In fact, the 'sport flying' segment is probably the perfect place for this technology to get an initial grip. Battery technology right now is still gonna keep overall run time fairly short, which is very well suited to the guy just looking for 30 minutes to an hour of cheap fun flying. And, with the relatively low power output motors that are currently available, smaller single seat airplanes are the best fit for these quiet powerplants.

 The rapid pace that things are changing is certainly making it seem possible that electric propulsion systems large enough for even 4-place aircraft may not be as far away as we thought just a few years back. In fact, the electric powered Cessna 172 concept from Bye Energy is a strong first step in that direction. That project, which includes participation from Cessna, is aimed at eventually getting an STC for the conversion which would make a 2-seat trainer that could fly for 2 hours and use no avgas at all. The concept seems to make sense... and it's unique applications like this that will slowly open the door for electric airplanes (and advancing motor and battery technology) to get a foothold into a market desperately in need of innovation.

 The biggest challenge for electric power for aviation seems to come from dealing with what to do about 'refueling' while on longer flights, or when traveling great distances. The infrastructure needed for replaceable batteries, or the technology advances required for 20 minute re-charging seem to be a really long way off. But overall, the progress already seen is pretty exciting.

 Lastly, it's interesting to note that the Cri Cri pictured here, with the Electravia motors totaling 70 hp, wasn't just barely able to get off the ground, it actually reached 162 mph, essentially the airframe's maximum design speed! They claim that using full power would have propelled it all the way up to 220 mph! When you consider that the Cri Cri is far from a 'motorglider with a massive wing', you can see that realistic applications for normal airframes powered by the electron are definitely on the horizon. I think I'm pretty happy about that... I wouldn't mind doing the little electric Cricket myself : )

Videos: Radial Rocket RG Drags Its Nose... But Not In The Air!

The new retractable gear version of the Radial Rocket

(1 pic & 3 videos)

 The new retractable gear version of the Radial Rocket homebuilt by New Century Aerosport is now flying! Even tho the original Radial Rocket is an awesome fixed gear taildragger (with the fabulous 360hp M-14 radial), the RG version has made the switch to tricycle landing gear. Why the change? Well, 2 reasons... one because there are a lot more people interested in an airplane of this high performance but with the reduced testosterone requirements of being a trike -- and two, because making the taildragger version into an RG would have been significantly harder to do. Getting long main gear legs that are attached forward of the main spar to actually have somewhere to go when folded would be a much bigger redesign of the existing airplane. For now, going trike is the best answer to the question.

 These videos give some great insight into the RG prototype that recently began flight tests. You'll see how it looks like a lean-and-mean version of a scaled down T-28 on the ground... and then it's just pure airborne beauty in the sky. If you're in a hurry, I recommend you watch about one minute of the first video below to see this gorgeous airplane inflight with the wheels tucked up. If you've got the time, stick with it til about the 2:20 mark to see the gear cycled.

 

 Then I suggest you watch the first minute or so of the next video (below) showing the airplane on the ground with that music-making M-14 running. Then hop down to the video at the bottom to watch the gear being cycled several times while it's on jacks. This gear is really fast! Looks and sounds solid as well.

Algie Composite Aircraft 'LP1' - 385 MPH At FL290 & 14.5 GPH?

Algie Composite Aircraft LP1 rendering and logo  (images: Woodward Aerospace)

 (11 pix, 2 videos)

 The LP1, or 'Light Pressurized 1', began over 15 years ago in the mind of David Algie. It wasn’t just an idea 15 years ago tho, work actually began on this airplane that far back, and the basic shape has been frozen for quite a long time. The LP1 is a two-place, pressurized, carbon fiber kit aircraft powered by an adapted Chevy Corvette LS engine that is intended to operate at altitudes as high as 29,000 feet (with sea level cockpit pressurization) and cruise at 385 mph burning just 14.5 gallons of fuel per hour. Even more astonishing is the goal for a 1,080 pound empty weight which will give this aircraft the ability to carry two 200 pound people, 50 pounds of baggage, and 62 gallons of fuel… all with a gross weight of just 1,902 pounds. Imagine the climb performance with 300 hp under the hood and such a light airplane!

 When I first saw the airplane at Sun-n-Fun in April 2010, the claim of 385 mph on 14.5 gph along with that flashy engine compartment, and the general feeling that this airplane wasn't designed the way were used to in the aviation world is what caused me to shake my head and walk away. The 2-seat carbon airframe with an elliptical wing claiming crazy high cruise speeds, sea level pressurization at 29,000 feet, and with an automotive engine tightly shoehorned into the cowl (and an unusual looking prop/spinner nose) pretty much told me this was just another crazy dreamer. I’ve been around homebuilt airplanes since the early 70’s, since before I was even a teenager, and I’ve seen a boatload of dreamers come along and make Bede-esque claims of wild performance coupled with low cost and build simplicity... but in the end, they all disappeared.

 But a couple months ago I had reason to be curious enough to find out more about that ’crazy’ airplane, and the research that day opened my eyes to what just might become one of the most revolutionary aircraft of the last 40 years.

Videos: Oshkosh Dreamin' As We Head Toward Winter 

 The high temp in northern Indiana today was right around the freezing mark, and with the clear knowledge that winter is on the way I found myself aching for some pure summer feelings... and that of course left me thinking about Oshkosh! It's pretty hard to beat a video (or two) from youtuber slickhutto for getting that OSH feeling stirred up, so here ya go! The 2009 Oshkosh video from Slick is above - I figured if you've already seen it, it's probably been a while, so it should feel pretty fresh...

 

...and this video is the one from 2010. Slick does a great job of capturing the real feel of Oshkosh, while also doing a fab job of editing. If you're a purist and would rather watch some Oshkosh without it bering a music video, check out Slick's youtube page for the more recent uploads that run 10 minutes and feature airplanes with all their natural (beautiful) sounds.

 I hope watching these videos inspires you to push ahead with whatever aviation project you're into. Whether you're building an airplane, learning to fly, upgrading your ratings, or maybe needing to fall in love with flying again (or just soaking up all the aviation knowledge you can find), watching moments from Oshkosh is one of the best ways to be motivated. I know it sure helps keep me going - thanx Slick : )

Burt Rutan And The Bede Aircraft Factory: 1972

Burt Rutan (middle) and the BD-5 at the Bede Aircraft Factory in 1972

 The aviation opportunities I had before I was even old enough to drive as a result of my dad's love for flying were pretty amazing. For example, to just scratch the surface, I was at the Reno Air Races 1968 thru 1970 (I was born in 1961), and at the last EAA Rockford fly-in in 1969 as well as the new Oshkosh location in 1970, and he taught me to fly at 13 in the brand new 1973 Citabria 7KCAB he bought... by the time I soloed in a glider on my 14th birthday, I had lived more aviation than most people get to in a lifetime. Thanks dad! He passed away January 10, 2009... please check out my tribute to Robert Clupper, my dad, and his amazing life in the sky.

 The whole BD-5 'Micro' revolution of the early 70's was a big part of my life as well. My dad had ordered kit #322 (out of 5,000+ that were eventually ordered) and we made several trips from Illinois to Newton, Kansas to check out the Bede Aircraft factory. The picture above is one my dad took on what might have been the first trip we had made there. It's pretty cool for a lot of reasons. It's cool because it shows the first of the all metal BD-5 prototypes (N501BD) with the newly configured 'stabilator' horizontal tail. The early V-tail proved to be nothing more than cool looking, and the subsequent change to the first generation 'standard' tail had also been full of complications. The solution was the larger, relocated 'flying tail'.

 The picture is also cool because the shorter guy on the right is Bede's new test pilot at the time, Les Berven. Les was not only sized very appropriately for the BD-5, but he was just crazy enough to be a good fit for the unusual 'Micro' flight test program. After the Bede years, Les went on to be the chief test pilot for the FAA's Northwest Mountain region. There, he flew Boeing aircraft during the certification process from the late 70's thru his retirement in 2001. Sadly, Les passed away shortly after retiring. This Seattle Times article on Les Berven gives some great info on his test pilot life.

 Lastly, and most notably, this is a cool pic because the guy in the middle, with the vertical striped shirt and biased striped tie, is Burt Rutan. When I look at the print date on the picture (July '72), it would appear that Burt had not been involved in the BD-5 program very long at this point. Burt's contribution to solving many of the 'issues' the BD-5 had was significant. Jim Bede has had some of the most unusual and potentially fantastic aviation ideas over the years, but there was often a gap between the genius of the ideas, and reality. It seems Burt's job at Bede Aircraft was to bridge that gap. Also, much of what Burt learned from the Bede years, both in aircraft design and business management, had a direct impact on the way he approached his own homebuilt aircraft business when he started the Rutan Aircraft Factory (which developed designs, but then only sold 'plans') in 1974.

 With Burt announcing that he will retire from being the Chief Technical Officer at Scaled Composites in April 2011, I thought this was a great time to start looking back at his most-amazing career in aviation. Watch for more little snippets of Burt's wild and interesting aircraft designs in the next few months. Also, you might want to check out this 2009 Air & Space interview with Burt Rutan - great stuff. 

 And hey, check out the pic below. Yep, that's me in the baseball cap at age 11, arms crossed and talking airplanes! The several trips we made to the Bede Aircraft factory thru the mid 70's gave me some fabulous exposure to this unique slice of aviation history. Check out some of my other BD-5 posts for a little more detail on one of the most interesting airplanes of all time.

CoolPix - Homebuilt: Fab Focke-Wulf FW 190 Replica At Reno 2010

(click pic for hi-res)

 When I was about 12, I built a 1:48 scale model of the short nose Focke-Wulf FW 190. I painted it in a really good camouflage scheme, and it was actually the only one of the many plastic models I built that I was really pleased with how it turned out. I've been pretty severely attracted to the FW 190 since those days as a kid, so I was very excited to see this one at Reno, shown here in a nice big CoolPix.

 It looks like this one was recently flown for the first time by Steve Hinton and is owned by Frasca International, the flight simulator people out of Urbana, Illinois. If I have my info correct, it's one of the FlugWerk replicas from Germany, and has a Pratt & Whitney R-2800 engine in it. It was raced at Reno by John Malony, but not hard and not as a serious contender. But wow, it was very cool to see it in the air!

 I was impressed with the paint job as the airplane appeared very authentic. Not a 'show plane' paint job, but one you could believe was representing the airplane just as it would have looked in the Luftwaffe. It also looked smaller than I expected by a little bit. The one or two I've seen before were in a museum, and seeing this one out in the open around other warbirds made me realize it's not as big as I had thought. Comparing dimensions to the P-51 Mustang shows that it is indeed a little smaller all the way around.

 The one thing that stirs me big-time about the FW 190 is those long, wide-stance, aggressive gear legs. It's the same thing that makes the Hughes H-1 and the F-8 Bearcat look so stinkin' hot to me. The P-51 is a very beautiful airplane, but its gear legs just don't affect me the way these other aircraft do. I know, I'm a weirdo... but I'm a very happy, aggressive-gear-leg-lovin' weirdo : )

2010 Reno Air Races - Picstream #3 Sunday 9.19.10 (14 Pix)

2010 Reno Air Races Unlimited champion Steven Hinton and team Strega

(14 pix)

 The big finale Gold Unlimited race for Sunday was cancelled at the 2010 Reno Air Races for safety reasons due to high winds and accordingly, winners were announced based on race statistics from thru the week. The championship for the second year in a row goes to Steven Hinton and team Strega. Second place went to Rare Bear and third to the P-51 Miss America.

 

Steven Hinton and team Strega proved thru the week that they were fast and reliable on the race course. Tho I'm sure they would rather have won the 2010 Reno Championship with a race on Sunday, there's no doubt that they earned the right to hold the big trophy.

2010 Reno Air Races - Picstream #2 Saturday 9.18.10 (14 Pix)

Making the T-6 racer 'Gunslinger' sparkle in the Saturday morning sunshine

  Saturday was a great day at the 2010 Reno Air Races - the weather was ideal and there was a lot great racing to watch too. Like in the picture above, a lot of time is spent by the race teams working on and cleaning up the airplanes. And as I've said before, being in the pit area to see all the work being done is simply amazing.

 The big story for me continues to be the way Jimmy Leeward has kept The Galloping Ghost alive in the Unlimited Class. The race on Saturday was an easy win for the highly modified P-51 Mustang, giving lots of hope to the idea that it can be a real contender. The big test will be the final race of the day on Sunday against the seemingly unbeatable Strega; the 'always-a-contender' Rare Bear; and possibly the very fast Voodoo. However, after pulling up and out of the race on Saturday, Voodoo's ability to race today may be in question.

 Here's a quick batch of pix from the day showing the wide diversity of flying machines, both in the air and on the ground, that make Reno's Stead Field a great place to be in mid September...

 

The first race of the day on Saturday was Formula One, and here the Biplane Class airplanes are watching as they are getting staged and waiting their turn.

 

Polar bear, and early A model P-51 that was crashed in Alaska back in 1944. It was eventually recovered and rebuilt, with first flight in 1985. It was a very nice addition the heritage-oriented fighters that were racing.
