Bisson told me that they have the mufflers in stock for the ZDZ50. If someone doesn't want to wait for he ZDZ50 , it can be ordered from Amelung Modellbau in Germany. They are in stock at $425 and $26 for the prop jig. They are not charging any shipping. I ordered mine last week and will have it before Christmas.
I live in the N.West and can fly most of the year.( When it isn't RAINING)

I just found out from RCS that Amelung is not even supposed to do any business in the U.S. RCS WILL NOT do warranty work if it is purchased from Amelung.
Sorry Guys
