Thanks!The official rules are already out...
Changes: The plane can be constructed of carbon fiber and tape, along with the materials from last year (Wood, glue, etc.). New maximum horizontally projected stabilizer span is 28 cm. No maximum chord measurement for stabilizers. Only one propellor and one motor can be used per flight.
Stiffness. Can be useful, but not necessary. Example, a thin layer on top and bottom of a floppy motor stick will stiffen it up greatly. Adds weight, but can be compensated for.carbon fiber? what would you use that for?
