Hello.

Webra engines are made in Austria. Here is the link:

It is correct that nitro is very expansive in Europe ( the price for one liter 98% nitro is about USD 23,00). One gallon with 15% Cool Power costs about USD 30,00. This is one reason why the Webra engine is designed to work with less nitro. Last month i visited the Webra factory in Niederösterreich/Austria/Europe. Mister Kaineder, the owner of the factory showed us everything from the beginning to the completely installed engine. It was very interesting. He also told us, that nitro is necessary, but only 15 to 20% maybe less. I think Japanese engines need more nitro.
By the way: whats the nitro price (about 98%) for one liter. Or one gallon with 15% nitro like cool power in the USA or Canada?
