People ask me about what happened to Valach (a name that no-one, me included, knows how to pronounce) and who Fiala are.
Indeed, Fiala is the manufacturer. Valach an OLD trademark they used in the past for the German market and in the beginning here in the USA through me.
But the company name is indeed Fiala, the trademark Valach.
Think of it as GM owning/using the trademarks Ford, Buick, GMC, Chevrolet etc.
Fiala has decided against rebadging their engines for the USA from here on out, we will now use the company name instead.
Hope all is well and keep them flying!
