Chris,
Here is the dilemma. See how it was added to the rules. For F1L, for
example, it is section d of the rules below. I do not see how a CD can
waive section d anymore than they can waive section a, b, or c. Here are
the FAI rules,
https://www.fai.org/sites/default/files/documents/sc4_vol_f1_freeflight_18.pdf
*3.L.2.*
Characteristics
Wingspan, maximum projected.....................................457.2 mm
Wing chord maximum...................................................76.2 mm
Stabiliser area maximum..............................................50%
of wing
*a)*Structure
1)Only balsa wood and adhesive are to be used for the basic structure.
Exempted are the propeller shaft, rear hook, thrust bearing, surface
holding fittings and reinforcements for their attachments. No external
bracing is allowed except balsa wood wing struts.
2)The motor stick must be a solid single piece of balsa. The tail boom
must also be solid and of one piece but may be an extension of the motor
stick. Balsa splices up to one centimetre in length may be used to
repair breaks in the motor stick or boom.
3)The propeller must be all balsa except for ground adjustable pitch
fittings, if used.
4)There are to be no devices for changing any part of the model's
geometry or torque during flight. Only the normal flexing of the
structure due to flight loads or motor forces is allowed.
*b) *Covering
1)Models are to be covered with any commercially available solid sheet
material such as paper or plastic.
2) Microfilm is not allowed.
*c) *Weight
Weight of the model without rubber motor shall not be less than 1.2 g.
*d) *The model shall carry the FAI unique ID number of the competitor on
the motorstick written with permanent marker or other non-removable means.
The competitor must be the builder of the models entered
