Great engineering achievement, finest water cooled 2-rotors Rotary Engine commercially available.

On early 2020, I met Toyan V-4 and single cylinder engine, I have gut feeling that this firm can produced high quality model engine. On about September, I have communicated to Stirlingkit that they can try to build Wankel Rotary Engine..........Now the dream come true : 2 rotors water cooled Rotary Engine, rotor chamber from steel with CNC wire cut, eccentric shaft believed is alloy steel, other parts from Aluminum CNC machine and grind, small enough to put on plam, but performance is great. A great alternative engine to put on model boat. Highly recommended to those model engine collectors.

Nice little engine

Nice little engine model,
high quality of elaborated parts.
I did not test how the engine works,
so I can’t answer about this but
mechanically, it looks good.
