FlyingPilgrim, (Oh how I love these handles)

Try these sites. Krumschied ship worldwide, but only Mrs Krumschied speaks good English and you can order on-line. You'll get all the technical speck in English on their site.

If you need a ZDZ motor and the exhaust I purchase all mine from ZDZ.de service is just amazing, however as your on the other side of the pond, you may need to use aircraftinternational or whoever can supply you. I think RCshowcase do them, (they are the US importer for ZDZ).

A picture paints a thousand words, have you seen anything as beautiful for an exhaust and boy or boy are they very good performance. You'll see you can even have a DIY for any application.
