Luscombe Phantom: Since I am arriving today at the National Luscombe Fly-In, I thought something from their inventory would be appropriate.

Don Luscombe, was a big shot at a little airplane company called Monocoupe during its early years and helped during the time Monocoupe was designing some of the most popular airplanes of the day and even producing some of the most popular engines. However in 1933 Mr. Luscombe embarked on his own journey. He founded Luscombe Aircraft Engineering Company.

Luscombe’s first design was the Phantom. If you squint really hard and look at it sideways, you could almost mistake it for a Monocoupe D-145. It is powered by the same 145hp Warner and shares the high wing taildragger configuration. It’s major difference however, was the construction method. The Phantom was made entirely out of metal. It had fabric covered wings and tail feathers, and everything else was aluminum skinned. It also featured an incredibly complex tunnel style cowling with individual passages for each cylinder. Another unique feature of the Phantom is its stainless steel split flaps that run almost the entire span of the wing including the majority of the aileron span.

The Phantom did fairly well in the performance category, however it was definitely on the luxury side of the airplane market and 1933 was not necessarily the year to be in that market. Only 25 Phantoms were produced before Luscombe moved on to cheaper airplanes.

This particular Phantom, is fresh...Continue Reading

I had a look in my box of goodies ..
I found a pair of 1.5g servos with JR connectors ..
And I still have a few FS2A Rx ( They be small ) that run fine on 1s .
So looks like I dont need to buy any stuffing for the Feather .

I will go with the laminating film for the wing covering .. Reading the instructions , apparently the tissue soaks in a lot of moisture .. And its very moist around here .
Interesting that the servos go in the wing .. That pod is small after all ( really small )

Ok . something to do when the weather is bad !

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 simply wanting larger front and rear supports (the U-shaped cradles) to accommodate my Radian, and then scope-creep took over. I've been re-designing of a number of components and playing with code changes, and learning a lot in the process.

The CAD screenshots show the removable pivot supports and snap-in wing pads which I'm currently trying; these enable easy changes to the pivots / pads without re-printing the supports, and also enable 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 for it. But it is easy and quick to use, and remarkably precise & repeatable.

It's a great project for someone who likes to tinker. Highly recommended, if that's you.

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

Here's a short step-by-step guide to building EdgeTX firmware for your radio using Ubuntu Linux. EdgeTX is a version of OpenTX, concentrating on new cutting edge developments.

In the first half of this blog entry, I show how to setup the build environment and the second lists the necessary steps to build EdgeTX. In the example, I use RadioMaster TX16S, but the steps are applicable to other radios as well, you just need to select another build target in the cmake line (more on that below).

After following the steps here, if you are interested to learn how to setup a graphical development environment for coding and debugging, please see my blog post #2, showing how to setup Qt Creator and how to perform real-time in-circuit debugging with it on code running on radio microcontroller.

Disclaimer: I have assembled this guide to the best of my knowledge. Nevertheless this is NOT the official guide of how to build EdgeTX, nor has it been verified by EdgeTX project maintainers. In short - if you run into problems, please consider first that it might stem from the steps here, especially before opening an issue in EdgeTX GitHub.

You will need Ubuntu Linux in version 20.04. The steps will also work when Ubuntu is running virtualized, such as on a VMware Workstation, VirtualBox or Hyper-V.

1. Setting up the build environment for EdgeTX v2.4
  • Download Ubuntu 20.04 LTS and install it (using Minimal installation type is sufficient. Allow Download updates while installing Ubuntu, 3rd

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.
