Extasy - Introduction

Extasy F3B sailplane


The model is manufactured by Jiri Tuma. Jiri created a special technology to make wings stiff and light enough for this thin airfoil. Also special is the space between fuselage and wing and V-tail as shown on the pictures . This will help to reduce interferences and drag. The model is built in double-carbon with carbon V-tail. Fuselage same as EXTASY in carbon and nose-cone 2,4 Ghz ready (Kevlar-Glas). There are 5-ballast tubes (3 in the joiner and 2 in the wing) which allows 1800g only with use of brass! No expensive wolfram needed ! Gunther flew this model 3 weeks after maidenflight on the last contest of the season on the „Oktoberfestpokal“ in munich and won the senior award.
