Introduction

 

Thank  you  for  purchasing  the  ZupAir  Zulu.    This  glider  has  excellent 
performance,  a  terrific  speed-range,  responsive  handling  and  great  aerobatic 
capability.  A true multi-use glider that can fly well at almost any site with almost 
any skill level. The wings can easily detach after flying, making this 1.5 Meter (59 
inch)  model  easy  to  transport.    If  you  don’t  have  your  Zulu  flying  already,  final 
assembly  is  a  breeze,  thanks  to  the  molded  airframe  and  pre-assembled 
components.  

 

We think you will  

enjoy whatever you do, with your Zulu!
