Argentinian Golden Eagle

Hello to all the friends of the forum. That engine is not a new version of anything ... it is simply a mix of parts that are assemble and sold here in Argentina by a hobby shop.
In the past and I think that died from the covid, there was a craftsman named Oscar Nocera. he designed and manufactured parts for cox engines, how Mauricio does. He even made complete engine that he called com. maybe Mauricio can give more imformation about them.
What I do have, which was manufactured by Oscar, is a back plate, with venturi and needle valve, all as totally manufactured by oscar.
here i left some images of what he made.
greetings from Argentina.
Nicholas
