Gliders are an easy way to enter the hobby of Aeromodeling.

Here are the Indoor Models that will be flown this year:

  • The Flying Aces event: Comet Phantom Flash
  • P-18 (7.5g min. weight rule)
  • Blatter 40 event. (its an ROG) club will provide kits / plans or build your own from scratch. I have plans! Volare Model airplane supply has the kits.
  • Tem Johnson Memorial Glider event
    (combo Indoor HLG and Indoor Cat-Launch glider) AMA rules.
Comet Phantom Flash 350

Phantom Flash

Almost everyone it seems last year had a P-18 and a Phantom Flash. This year the Blatter 40 will replace the Peck ROG.

Easy B 350

A P-18  (wingspan 18″) is similar to an Easy B

With the passing of Tem Johnson we will now have the Tem Johnson Glider Memorial Trophy as well 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.penny plane 350

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.

You don’t have to be a member to watch a flying event and the admission is free.
