Hi Everyone!

New-ish to RCGroups but spend a lot of time in quite a few RC groups on social media. I'd like to spend more time here for several reasons. One being I sell things here and there and Ebay is getting RIDICULOUS with the way they treat sellers. Regardless, I'd like to invite anyone to check out my YouTube channel, Inverted Adventures! It's small but growing, and covers a lot of my RC Car and Airplane related adventures! I also have a matching social media page for those interested with keeping up between videos.

This is the long-form of my journey of the K&B 15RS (aka Wart, aka Racing Schnürle). First, I must acknowledge my friends without whom this project would have been impossible. Luke Roy (of Rattler fame) provided invaluable data. He has an original barstock case and sleeve from the prototype phase plus one of the investment case cases that came after the 15RS. This provided the details of the sleeve porting and case transfer shapes. Luke also reverse-engineered the stroke based on the cylinder bore. Bill Hughes contributed detail photos (aka Mug Shots) of Glenn Lee’s engine used at the 1964 F2A WCs. Additionally, he provided certain critical dimensions and important information like the engine used a K&B 15R rod. Darron Black (aka “Boy Wonder” because he reminds Dub and me too much of ourselves at his age) is a friend of Dub and mine that provided invaluable support for me learning Autodesk Fusion 360 and identifying Shapeways as a source of 3D printing directly in aluminum. Bill Wisniewski, of course, is the designer of the of the K&B 15RS and provided critical information about its design and development in personal conversations. And last, but not least, is Dub Jett, my life-long flying partner and friend who supported my efforts with his excellent advice. As the Beatles’ song says “I get by with a little help from my friends”!

The precursor of the K&B 15RS is the developmental prototype engine by Bill Wisniewski used to incorporate schnürle porting into...Continue Reading

An alphabetical stroll through the history of aviation. Day 24, X

Vought XO5U-1: Since the US military likes to give every experimental airplane a designation that starts with X, there’s an endless list of X airplanes. So how about one that is completely irrelevant in the history of aviation?

Between the wars, the US was looking for a catapult launched, single float, biplane with folding wings. The contract eventually went to Curtiss for the SOC. But several companies took a shot at the contract. Vought’s entry was the XO5U-1.

The XO5U-1, or O5U if you don’t want to type so much, was a high performance biplane with dramatic tapered wings, four ailerons and huge flaps on the upper wings. It was powered by a large Pratt & Whitney R-1340 so presumably it was quite the performer. The O5U which was essentially a continuation of Vought’s earlier biplane designs, had one really cool feature that most other catapult launched floatplanes didn’t have. It was amphibious. A very narrow, tail dragger gear was retracted into the center float. I’m sure given how narrow, top heavy and short coupled it was that it was a real treat to handle on pavement.

The O5U was a real barn burner in the production department with a whopping single example. Since it didn’t win the contract, obviously it never went into production. It managed to survive almost a year until it was crashed in 1938. Kind of a bummer that such a cool high performance, unique and cool looking airplane didn’t amount to anything.

An alphabetical stroll through the history of aviation. Day 23, W

Waco CRG: Who doesn’t love a racing version of a cool airplane? The CRG bears a striking resemblance to the Waco Straight Wing but is significantly cooler.

In the 1920s, Ford was sponsoring an event called the Ford National Reliability Air Tour. Essentially a big circle flown around the wester 2/3s of the US, covering nearly 5000 miles. In 1928 Waco won the event with a Waco 10 and in 1929 they won it again with John Livingston flying a Waco 10/GXE/O series airplane. So when 1930 rolled around the pressure was on for Waco to clinch the win again. They turned up at the starting line with two freshly completed CRGs.

The CRG was very similar to a standard Waco Straight wing but housed a few neat tricks. Firstly the wings had been modified with a new racing airfoil. Secondly, the landing gear was significantly lengthened. Since the new airfoil stalled at a higher angle of attack, the longer gear allowed for a perfect stall at three point attitude on landing. Lastly, they bolted a 240hp Wright R-760 to the firewall.

After some extremely questionable rule changes in the Ford Tour that conveniently allowed the Ford Trimotor to win it, the CRGs took second and third place flown by John Livingston and Art Davis. After the race, one CRG managed to find a career as a skywriting airplane that allowed it to survive to the present day. It was restored quite some time ago and is currently flying across the...Continue Reading

An alphabetical stroll through the history of aviation. Day 22, V

Vulcan American Moth: Between Vultee and Vought there is a whole plethora of V aircraft but I figured I’d pick something a bit more obscure. The Vulcan American Moth was an early monoplane with a surprising amount of history packed into it.

Designed in the late 1920s by the Doyle Brothers, graduates of Harvard and Yale, the Vulcan was the first of a confusing line of monoplanes. The Doyle brothers, fresh from college, joined forces with William Burke from the Vulcan Last golf club company. Together they formed Vulcan Aircraft Company. Their first design was the American Moth. Named such as an attempt to gain a little popularity from De Havillands success.

The American Moth was a two seat parasol with a conventional landing gear and a series of radial engines. The front passenger had to remove the section between the cockpits to get into his seat. The prototype actually had a bathtub style cockpit that went all the way around both seats. The moth had a whopping production run of 8 airplanes.

The Doyle Brother’s left the Vulcan Aircraft Company later that year and started their own company. They produced the Doyle O-2 Oriole and Vulcan Aircraft became Davis Aircraft which later produced the Davis D-1. (my all time favorite classic) Each of those will have to get their own write up one of these days.

There is one surviving Vulcan American Moth however it was more or less destroyed in a bad accident years ago and it’s wreckage is still floating around in some California hangar awaiting an owner with the will to restore it.

We are making available for immediate ordering our larger (30" wingspan) interpretation of the Leadfeather 3D Delta including a KF4 airfoil (theory) which not only gives the plane great flight characteristics, it also strengthens the wing significantly. We have increased the fuselage thickness to 15mm EPP to strength it. The KF4 airfoil (image) complicates the wing building over and above a typical flat foamie. (but the end results are well worth it) http://www.racores.com/DDDeltaXL.html

Also, you should be aware that the build uses more than 2oz of Foam-Tac to complete.

Check out the associated flight videos on our 3D Delta XL playlist as well as the full instructions online

Hi, I live in Sweden and is looking for a Hitec 61076 HG3XA gyro, used or unused but in good working shape. If I buy from a company I have to pay a lot of extra costs, with shipping more expensive than the gyro. I will be open for any advice, spring is coming, tomorrow around 68F in Westervik.

This afternoon, I bought the HobbyZone Super Cub RTF (HBZ7400) from an RCGroups.com member. Total paid was...

$175.00 (Plane ARF Kit, Engine & Radio!)
$23.99 (Shipping)
$N/A (Tax)
$198.99 (Grand Total)

This plane is discontinued but is still NIB! It's the color is blue and white (I have the red/white w/SAFE) but I got this one b/c the receiver includes the X-port which can be used with the different HobbyZone modules (i.e., Aerial Drop Module, Sonic Combat Module, Night Flight Module)!

I tried finding one online and saw one recently on eBay but it was used and the guy said it needed a new battery but wasn't sure if anything else was wrong, plus he was asking $99+$148 for shipping so after taxes, it would be around $250 and no guarantee everything works. But get this...


I'll update this with pics and an unboxing video later but I'll also include some more details that I don't have time to blog right now, such as my wanted ad and the other NIB I almost got from a hobbyshop - man that guy was a jerk! But so far, it all worked out thanks to a nice RCG member named Derrel!

Stay tuned...

I'm new at this stuff so forgive my ignorance! Is it possibly to use the Receiver in a colossal heli which takes 11.1 v battery. Can the receiver handle the voltage.

E-Flite Valiant 1.3m BnF Basic

5/3/2021
I decided a while back that I wanted some good high wing taildraggers. Probably the main factor in my coming to that conclusion was the Hobbyzone Aeroscout with a nose wheel. Crashing it or even very rough landings often leads to cracking the fuselage or breaking the nose off. I have probably had to repair the Aeroscout more than 6 times because of damage caused when that nose wheel hits the ground wrong. So after some research I bought the Night Timber X. I have not flown it yet, just finally got it paired with my Spektrum transmitter yesterday because I am new to Spektrum and there are not really any easily found complete instructions on binding a receiver to a Spektrum transmitter. I spent several hours searching and studying how to bind it and finally put enough information from different sources to get it to work, but the Avian smart esc may not be working right, so no motor reversing. Spektrum transmitters may be good, but binding, programming, and setup is not simple. I have been using Detrum transmitters/receivers, and they are more user friendly.

So after reading both Night Timber X threads all the way through, I wanted something else to read, and found the Eflite Valiant thread, another BNF high wing tail dragger. Reading about it made me decide it might be the next plane to get. So I thought if I wait a while, maybe there will be some kind of sale on it. Friday or Saturday I got an e-mail from Horizon...Continue Reading

ELF DLG , been a long time (14 min 4 sec)


I really like the ELF , amazing technology built into a 2ch glider .
Lift ? Where is the lift ?
I got teased by some rising air , just a tease . We just dont have much lift around here , lot's of sink , but that lift .
Next time I will try a lighter / smaller battery and have a more rearward CG .

Rusty flying on my part . Quite a few times I pushed the nose over too quickly , I might have got another 10 meters if I did not pull the trigger so early .

Completed a 1/48 Scale Revell T-6G Texan. I got this 1991 kit for $6.00 at an estate sale last summer.

It is to honor Russell O'Quinn, God's test pilot. Russ learned how to fly much earlier, but he had to take lessons in a plane just like this at Hondo AFB west of San Antonio, Texas. I weathered mine by griming it up a bit because in 1949, dirt and dust was a constant there. I do plastic models so that one day if and when I make an RC version, I have a good resource for reference.

Russ went on to test and even design jets for the USAF. His testimony is outstanding! I can highly recommend this recording:

Hi to all who are willing to discuss this issue. Recently I received plans and instructions to build a Stearman PT13, the plan dated 1981. In instructions reference is made to epoxy(understood) then still talking adherents they say to "hot stuff" an undercarriage wire in place. Does "hot stuff" equate to using a hot glue gun? I would appreciate any imput to my query.

I am at it again! Garden work is mostly finished.
Covered one wing and the tailsurfaces and test fitted the tail. I only had to do minor adjustments and glued the stabilizer to the fuselage. Test fitted the tailplanes and tested the swing. All went well.
