To continue the topic of large and light aeroplane models I suggest having a look at the stages of constructing AN-14 Little Bee.
Wingspan – 2.6 m
Weight – 1.9 kg


I had been planning to construct this model for a long time until all stars were aligned to seize the chance. Still a low-end model should be physically alike to its prototype. Once I have already made a post on one of my models I-16

However, let’s take a look at Little Bee. While making drafts I found plenty of mismatches in terms of section sizes. This fact made me confused, and when I started working out the model I realized it would be impossible to construct something light enough using these drafts. I decided to take a different way and to make a model hull according to the drafts, but the insides would be adjusted as the process advances. As a base for the project the following draft of a paper version was taken:

In accordance with this draft I constructed the model hull, a tail and keel beams. The rest was made in the ordinary course. This time I decided to illustrate the process more. There might be some mishap in the order of the photos since there are lots of them. If you’ve got interested, feel free to ask any question. I’ll answer it with great pleasure.







Here is the video of the flight. The flight itself was fine, however the end of it is left to be desired. I have already lynched myself for it, but what happened can’t be changed. The next little bee will be made lighter as now I know the details of the process.

Spread – 2.6 m
Weight – 1.9 kg (But it is also possible to make it lighter - 1,7 kg)

Here are the materials used when constructing the model:
Padding for laminate flooring – 5 mm
Acrylic paint
Colorants
