INTERIM RULES
GOVERNING THE PURCHASE OF THE CLASS SAILS
These
rules are to be in effect until 100 Flying Tigers are sold and delivered.
It is the intent of
HipTrader (the builder) to limit class sails used in class-sanctioned events
to those provided by HipTrader.
At that time the
owners and the class association will convene to review and adjust the rules
covering the purchase and manufacturing of the sails if deemed necessary.
As you know it has
been the intent of HipTrader and everyone involved to build an affordable
“Club Racer”. To this end we think it is imperative that we keep the
OVERALL cost of owning a Flying Tiger as low as possible.
We are all dedicated
to building the Flying Tiger for many years to come and feel we are “Well On
Our Way”.
Sincerely,
Bill Stevens
Flying Tiger Class Association Sail
