I'm working on a comic-scale version of the Mambo with 28" low AR wing and 1/16" slab side fuselage.

Since I can't leave things alone, even the well-proven fuselage box, I decided to work in some truss members behind the wing. Obviously the grain wouldn't work well as-is, so I came up with 9 different options for the truss members.

Results on the third photo.

I list them here in roughly ascending order of preference. I will be going with #8, since it feels like the right amount of stiffness and durability. Definitely I will be saving some balsa weight from the cutout sections and even what would have been some balsa truss.

I've used similar techniques in a very small Telemaster and a 92" Guillows Javelin (400%) with a 7-foot long fuselage. The balsa/carbon bond (with CA) is not a problem but could be reinforced if needed.

I've been tinkering with my build of the Arduino-based CG scale. It started with wanting larger front and rear supports (the U-shaped cradles) to accommodate bigger planes, and grew into re-designs of a number of components and a lot of playing with the code.

The CAD screenshots show the removable pivot supports and snap-in wing-pads which I'm currently trying; this enables easy changes to the pivots / pads without re-printing the supports, and also enables having multiple locations for the pads in the rear support.

I know there are various ways to measure CG/AUW, and this is not the simplest or cheapest device. But it is easy and quick to use, and amazingly precise & repeatable. And it's a great project for someone who likes to tinker. Highly recommended, if that's you.

More info about them:
Questions and comments are welcome.

Cessna Model A: You may have heard of this small airplane company called Cessna. No? Well let me tell you a little about them.

Clyde Cessna built an airplane from scratch using some ideas from Louis Bleriot and called it the Sky Streak. In 1911, it became the first airplane to fly between the Mississippi River and the Rocky Mountains. (in Enid Oklahoma) When Cessna couldn't get any more money from the bankers in his area, he moved to Wichita Kansas. In 1927, the Cessna Aircraft was officially started.

Cessna’s first official product was the Model A. The Model A was a four seat traveling airplane. As were the times, it was quite large for a four seat airplane with a 40 foot cantilever wing. It was an exceptionally advanced airplane for it’s time. It was very early into the radial engine game originally being powered by a ten cylinder two row Anzani radial of 120hp. Following airplanes were powered by Comet, Axelson, Siemens, Warner and Wright radials of increasing power.

Cessna Produced 83 A series airplanes before the end of it’s run. Cessna decided they would scale up the A model for six seats and they designed the Cessna DC-6. On the day the DC-6 Type certificate was authorized, the stock market crashed. They did manage to produce a few of the DC-6, however the company was inevitably put out of business by the depression and wouldn’t be back again until 1934 when the development of the Airmaster began.

There are at least two complete Cessna A series airplanes...Continue Reading

This tool will make it easy for you to make a perfect CA hinge.
Also will be a standard hinge making tool for all Craycle models.

In addition, a hinge design has been made that you can use for your own balsa and foam models.

You decide which flexible material you will use as a hinge. You can use special materials produced for this, or you can use an easily accessible material such as nylon film (for example: acetate film).

Note: You must print the Hinge Maker at a layer height of 0.15mm.

Follow us for the next projects.

Here is a 3" tether car powered by a Cox Tee Dee .010 engine.
The body is a Tootsie Toy piece. Had to do a good bit of grinding on it
to get it ready. I messed up on the cylinder opening. Decided to make a
gear choice change after I had cut the opening out.
I fabricated the frame and fuel tank from K&S brass stock pieces.
Used solder to hold it all together.
Gears and axels are slot car parts.
The wheels are Dubro tail 3/4" airplane tail wheels drilled and
tapped to fit the axles.
The brass screws are 1-72 thread 1/4" long.
I'll fill the cylinder opening and paint the body one of these days.

Halloa people

first video on an (for most) unknown radio / radio-brand and I've combined it's maiden with a first plane of the ZOHD Drift...
The Drift isn't a new-new plane ofcourse.. it IS new to me though :P

Soooo a Wfly ET16S radio.. Ever heard of the brand?
Also: it was sent to me for free.. Just so you know...

Let's at least see if the plane + radio combo results in a flight

New Radio + New Plane + New Camera ! :O What could go wrong :P (14 min 17 sec)

Yep Les Amis,
SMO or NAKED ? That is the question ! J'ai en test depuis quelques temps la petite Insta 360 SMO qui a été développée en collaboration avec BetaFPV. J'avais quelques aprioris sur le fait de devoir passer par un logiciel de stabilisation mais tout compte fait, quand on compare à la difficulté d'obtenir ou de se fabriquer une Gopro Naked et à sa fragilité, c'est vrai que la SMO est un excellent compromis niveau rapport qualité prix et utilisation. Donc j'adopte aisément cette nouvelle petite caméra pour mes prochains vol en HD, que ce soit sur des petits ou gros racers. La coque solide et les lentilles de protection sont très rassurants en cas de petits crashs ou contacts ( j'en suis déjà à ma deuxième Naked et un objectif changé sur la deuxième ! ). En bref, je valide ! ... Prenez soin de vous et merci à tous pour votre soutien .
