Puma 13.5
Owner’s Manual
VG Set-up
The VG on your glider should be factory set. However the ropes do stretch a little and it may be necessary to
adjust the ropes to retain full VG Travel.
Figure 2: VG. Travel set-up
NEVER ALTER YOUR GLIDER OR VG IN SUCH A WAY AS TO INCREASE THE MAXIMUM
TENSION OR REDUCE THE MINIMUM TENSION.
BATTENS AND BATTEN PROFILE
The Puma battens should be maintained in the correct profile. Failure to do this could result in adverse flying
characteristics. Batten profiles for all Avian gliders can be obtained from Avian Ltd. The correct profile
must be used on the appropriate glider.
Batten Material
The nose batten are made from 1/2" OD 6082 aluminium alloy tubing.
All other battens are made from 10.6mm OD 7075 aluminium alloy tubing.
6082 Alloy tubing is softer and easier to bend. 7075 alloy is harder, more difficult to bend and more brittle
but it holds its shape much better.
How often should your battens be checked?
At first check your battens regularly. This will give you some idea of how fast they are changing profile. The
Puma has 7075 battens which tend to hold their shape well. The nose is made from a softer 6082 alloy. 6082
battens tend to get harder, and hold their shape better, once they have been re-profiled a few times. On the
Puma the batten most likely to require re-profiling is the nose batten.
Don't forget: If you don't know how the glider has been treated while it is out of your care (for instance if it
has been sent by carrier or on an aeroplane) check the battens against the profile and do a very thorough pre-
flight check
BEFORE
flying.
