List of Indoor Models that will be flown this year:

  • Comet Dimescale Model PlansDime Scale
  • P-18 (7.5g min weight rule)
  • Comet Phantom Flash — A Flying Aces event
  • Tem Johnson Memorial Glider Event —This is combined Indoor HLG (Hand Launch Glider) and both Indoor CLG (Catapult Launch Glider) events, AMA rules. Best time from any of the three events counts.

This year the Dime Scale category will replace the Comet ROG. Almost everyone it seems last year had a Comet Phantom Flash. Note that if you built a P-18 for the Stars and Aviators Mass Launch event you can use that one you built for each month’s contest as well as the year’s end contest. Know that you can’t use the flight time the plane had in the Mass Launch for your official time.  Official flights must be flown separately.

With the passing of Tem Johnson we now have the Tem Johnson Glider Memorial Trophy for the accumulated points. Any indoor glider design which meets the AMA rules can be flown. Cat Glider is just as difficult as hand launch. You get to count your highest score of either plane for each month.

Indoor Free Flight Models are very light, slow flying models powered by twisted rubber strips driving a large propeller. Hand launched gliders and gliders catapulted into the air by a loop of rubber strip are also flown indoors. They are flown in school gymnasiums,  auditoriums, and similar large open spaces. It’s not unheard of to have typical flight times
of several minutes powered only by a small rubber band.

Indoor models are one of the least expensive and simplest ways to get started in aeromodeling.
You don’t have to be a member to watch a flying event and the admission is free.
