Further Development
At this moment (january 2013) all molds are made. Initials tests showed that chosen materials will not provide mass production. The epoxi sodden wood is not so enduring at it seems. The mold part can withstand only couple of tens impacts, while we have to make four or five impacts per one aircraft. These circumstances lead to us to only ten sets of planes possible.
The total cost of the work done already exceeded ten thousand
Further investment on our own is not possible, we need help from the outside. That's why we went to the indiegogo for crowdfunding.
Please, rcgroup, don't stay aside - even smallest help can make a dream come true
. One or two usd could make this project real.
Overall progress, as always, can be seen on our blog

Hello, rcgroups! I'm Serge from Russia and I represent the "ssair" brand. Since my childhood I’ve admired big civil aircrafts but up until autumn 2011 I did not dare to fulfill my dream - to have a big beautifull rc aircraft. So, I've started looking for a suitable aircraft in the market. And what I’ve founnd - there are a lot of uneven foam planes and nice but expensive plastic projects. And here it comes in my mind - wait a minute, I can do it better and cheaper! I chose the Boeing 777, I really love it. Ok, let's begin. First of all, I have to choose the material.
What we have - balsa, foam - cheap and lightweight. Ok, but how does it look like? - uneven bumpy surfaces and in regard to repairs after the crash – a lot of work, as much as to make it from scratch. Not suitable for us.
Ok, let's take a look at fiberglass. Glossy smooth surface, very well looking. But what about the complexity of the process? I have to make molds, learn technics and etc, at the end I'll have lightweight strong cowls but what price should I give for it? – a lot of hard work? And what about repairs? And the density of fiberglass is not as low as it seems - 2.4 and more g/cm3 - like aluminium. Not suitable again.
And this way I came to petg, to be exact to the manufacture of parts by vacuum thermoforming. You may ask - what about stress load of aircraft made of petg? - ok, we will use an frame made of alloy and carbon rods. This construction will take point loads (chassis...Continue Reading
