Toni Clark practical scale GmbH
32312 Lübbecke 25.
Herewith several photo's of my TC Piper.
This Piper took roughly 400 hours to complete; spread over 4 months.
Is powered by the Titan ZG 38SC and the stainless steel silencer
#3877 with intake air being sucked out of the fuselage.
Covering is coloured ECOTEX film. Radio is JR SX 9 servos plus
two sets of Nicad batteries. All up weight is 9 kg.
First flight without slightest trouble. Must get used to the very
effective wing flaps.
The engine started and run perfectly with surprisingly little vibration
(20x8" propeller 6500 rpm).
