A plane based on previous Kauba's design Sk-257. The V5 was experimentall fighter who was supposed to out-perform german Fw 190. The plane was supposed to be powered by a 1,750 hp (1,305 kW) Daimler-Benz DB 603 liquid-cooled inverted V-12 engine (you can also find two of those engines in Me 410). Thanks to this engine, plane was supposed to be able to achieve speeds more than 700kph in straight flight.
V5 was designed in 1943 and never met serial production.

My replica features detailed cockpit

To start the engine, you need to activate all switches on the right and then press "START" or A1.
To activate cannons, you need to press switch on far left.

I made two versions of the plane. One in German livery and you can download it on this post. The second one is fictional Czech livery and you can download it here.

Modded maps I used for screenshots:
