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
