The P30 class is a model category that caters to those people who want to
begin in an easy
to fly contest class. P-30 is a common beginner's event. A P-30 must
use an unmodified commercially available plastic propellor. P-30 has a maximum
wingspan of 30 inches, and uses 10 g of rubber. The empty airframe must weigh
at least 40 g. The Rules outline all of
the requirements for the P-30 Class.
This was one of the first model airplanes I ever drew up on a paper plan but I didn't follow through and build it correctly. When I flew it, it would just hang on the propeller and stall. It was not for some time that I would discover that it had no longtitudinal dihedral. There are plenty of airplanes in this class to buy as kits and all are fairly easy to build.
