OCD Club's Indoor activities are currently suspended due to the unavailability of a suitable indoor flying site.


Indoor Model Airplanes

Indoor model airplanes are light and delicate.  They must be flown inside a building, protected from wind and turbulence.

For example, the highest level of indoor aeromodeling is the F1D class.  Limited to 55 cm wingspan, about 22 inches, weighing no less than 1.2 grams, a dollar bill weighs one gram, having a rubber strip motor weighing no more than 0.6 gram, using 1/64" square spars of 4 pound per cubic foot balsa wood, covered with plastic film that looks like a soap bubble, with 2,200 turns on the motor and a propeller revolution rate of once per second, these planes are capable of 37 minute flights.  To achieve such performance requires very still air.  They are so delicate that the wake from someone walking by can destroy them.

A Pennyplane is limited to weigh no less than an old US penny, 3.2 grams, and to 18" wingspan.

A Mini-Stick is limited to a 7" wingspan.

Many sport models are built just for fun, although our club might have a contest for a class of such models.

There are also scale models in several sizes.  Peanut scale is limited to no more than a 13" wing span.
