Joyrider: Undercarriage

With the fuselage finished it’s time to focus on the undercarriage. I’ve got two major objectives concerning my model: I want to have the capability to take off from smooth runways and I need a suspended undercarriage in order to dampen jolts during landings.

That’s quite an order on such a small model. Since I don’t want to put tundra wheels on a biplane, I probably won’t even be able to take off from mowed grass runways, but tarmacs should do. As a principle I don’t want to omit the undercarriage because on the one hand it offers some protection to the propeller and on the other hand it’s just part of a prototypical look. In fact I only know of one biplane with retractable gear, that being the Polikarpov I-153 “Chaika”.

Deltang Tx22 Completion

Wiring the ground first.

After assembling the transmitter, I proceeded with soldering the parts. This turned out to be a fiddly affair, which kept me from taking pictures. In return, there’s a video of the final testing! 🙂

Overall one can say that the manufacturer’s documentation works very well. Once you’ve found your way around the diagrams and schemas, the assembly is easily done in a few hours’ worth of time.

It is really helpful to plan the wiring in levels or layers. At the bottom, I placed the ground connectors. There I connected the potentionmeters, the main switch, its LED and the bind switch. The two function switches remain untouched for the moment because after soldering they will partly block access to the potentiometer.

Joyrider: Nose

After framing the fuselage, the nose had to be tackled. This was the first time my skills got stretched to their limits and I had to rebuild repeatedly.

The main challenge was the quite accentuated curve that I expected the stringers to follow. I did manage to bend them accordingly on the fuselage’s halves while they were fixed to the construction board and the fixtures seemed to be stable. However, while trying to join the two halves I overtaxed the wood glue.

DelTang Tx22 Assembly

As I have already mentioned in my post on powering my porter loco with Li-Ion accus, I’d like to experiment with the DelTang system. There’s a lot of positive feedback from other model railroaders and all my requirements seem to be met – with further room for improvements.

Unfortunately, with the upcoming Brexit the demand for DelTang components has skyrocketed at the moment (meaining autumn 2019). I was lucky to get my hands on one Tx22 transmitter and two Rx65c receivers. It will suffice for the moment, but I will need further components, especially spares.

New Construction Report: Biplane “Joyrider”

About half a year after I started flying with my EasyGlider the desire for another model aircraft grew stronger.

I soon realized that I’d have to build my own models rather than buy premade ones. Especially larger models would quickly overtax my financial abilities. However, scratch building can consume a lot of money, too. So I decided to test my will: Do I really want to build a model aircraft from scratch?

Thus an old cardboard filled with balsa wood was ravaged, following the old saying: it only costs time. Taking stock, I realized that the materials wouldn’t quite suffice to build a whole plane. However, it would suffice to put my endurance under proper scrutiny.

Saddle Construction

Hey everyone,

Saddle template

Saddle template

got some progress and some pictures!
I started constructing the smokebox saddle. Since I own neither a lathe nor a milling machine I’m trying to make virtues out of necessities and hone my manual skills. The first step was to make a gauge for the saddle’s curves, so I could construct two symmetrical and identical parts.

Trailing Wheel Revision

Hello everyone,

here’s what happened the last few days.
First off, I constructed a simple tablet-like working space, so I can work on small parts in the living room without having to clean up everything afterwards. In the future I will saw new parts in the workshop, then take the half-finished parts and the fine tools to the living room, combining the best of both worlds, so to speak.

Trailing Wheel Bearing

Hello there,

Drills holder

Drills holder

it’s 8 am, thunderstorms are rolling in after a week of intense heat (thermometer topped at 110 °F) and I can finally spare some minutes to keep you updated.

Last week I ordered a whole set of small drills, so far I had a very limited stock. Now my options are quite unlimited when it comes to making threads and clearance holes. I spent some time in the shop building a neat set of holders.
