Chernov, Annenkov and others: the aero products of Russia's Samara region

[Stargazer]

It is a very complicated task to sort out the various seaplane designs that have originated from the Russian Samara region. Although they can be traced to only a handful of designers, they have been produced by an array of companies of various sizes, such as AeroSamara, Gidroplan, Aviateksim, Gidrosamolyet, Status-Avia, Aerovolga and others.
No English-language page deals with those in a proper way and even our forum doesn't have much on the subject. Also, despite their being popular and often exported, those seaplanes are usually produced in small quantities (often custom-built) and are relatively scarce in the Russian civil register compared to other types.

This topic attempts to list as many of those designs as possible. I'm proposing here the following breakdown:

1. CHERNOV-related designs (Chernov, Gidrosamolyet and other Che- types)
2. ANNENKOV-related designs (Chaika, LA, Aviatech, and other L-/La- designs)
3. Other designs (AeroSamara, Masterov, Elitar)

1. CHERNOV-related designs

First of all, I invite anyone with an interest in the subject to refer to the parallel topic I created in the Aviation & Space section, in which you will find many photos of the types listed below:

2. ANNENKOV-related designs

In the same way that all of Chernov's design share an obvious family resemblance, so do Annenkov's. The characteristic double-fin surmonted by the horizontal tail is a trademark feature of nearly all the family of designs stemming from the initial L-3 prototype of the late 1990s. I will soon start a dedicated topic for all those types in the Aviation & Space section, in the same way that I did with Chernov.

3. Other designs

Okay... so I cheated a bit when I made this a "seaplanes" topic... Indeed, there are also a few aeronautical products of the Samara region that are strict landplanes, and since most of them came from Aerosamara, it made little sense to leave them out...
