Hello gentlemen, Toni and Gerhard
Last week I did the maiden flight with "HMS-Piper mit Edelstahlschalldämpfer und Titan ZG 62SL". It really was the nicest surprise I ever have had in my RC-hobby.

1. The "aggressive Titan magneto engine" did nicely and neatly the unbelievable "hinten mit links" as you have promised.
See the short .mpg video attachment with sound (120KB).

2. The engines bass-sound was music to every RC hobbyist - thanks for the "HMS-system" and Edelstahlschalldämpfer"

3. The Piper itself was a really good flying airplane, even in aerobatics as you have written in your material. So you can have "serious fun" with scale oriented flying and also have "real fun" with miscellaneous aerobatics flying. I have not tried aero towing, but I am sure it will be "endless fun".

The reason why I decided to buy your product was:
flying capabilities - engine handling - balanced scalable combination of the Piper kit, engine mount, silencer and the engine. All this was made possible your good WEB-site with lots of written material and pictures.

Thank you!
