Reproductions of the JASCO Free Flight beginner series of models

This is a rubber powered model intended for spirited climb performance. It has a 12" wing span. Construction is mainly balsa with a spruce tail boom. The original kit came with a made up prop assembly consisting of a plastic prop hanger and a 5.5" diameter prop. The plastic prop hanger fits over the nose of the balsa motor stick. A simple alternative to the plastic prop hanger is provided in the drawing package. The alternative design uses some 1/64" plywood, some balsa, and a Peck thrust bearing.

Please note that the dihedral joints on the wing are angled when viewed from the top. This is part of the built in trim for the model. It is set up for a right spiral climb. The rudder is set for a right turn and the angled dihedral joints help set up the model for a flat turn to the right.

Thanks to Carl Dowdy who provided scans of his X-12 kit contents for the development of this reproduction drawing package. The CAD drawn plan package including a scan of the original kit plan is provided along with a parts layout for printing on letter size sheets of T-shirt transfer paper. As an update to this material, a 3D printed propeller hanger has been created. The 3D print file is presented below.

This is a rubber powered model intended for spirited climb performance. The kit box indicates it has an 18" wing span but the measured parts show the actual span to be 17.5". Construction is mainly balsa with a spruce tail boom. The original kit came with a made up prop assembly consisting of a plastic prop hanger and a 7" diameter prop. The plastic prop hanger fits over the nose of the balsa/spruce motor stick. A simple alternative to the plastic prop hanger is provided in the drawing package. The alternative design uses some 1/64" plywood, some balsa, and a Peck thrust bearing.

This is a 12" span model used as a hand launched glider or a catapult glider. Construction is balsa and a spruce tail boom. The kit plans shows the set up for each glider option and provides good flight trim instructions.

Please note that the right dihedral joint on the wing is angled and that the rudder has a built in left turn offset. This is part of the built in trim for the model. It is set up for a left turn during the glide phase of a flight. The angled dihedral joint helps control the turn so the model will not spin in to the left.

This is a larger glider, but still small enough to be flown in smaller flying sites. The kit box shows the wing span to be 24". Measurement of the parts show the actual span to be just a bit more than 23.5".

This model is flown by using the hi-start method or by hand towing using a special towing set up. Hi-start glider launching uses a length of rubber strip that is attached to a tow line. The model is attached to the tow line with a slip off hook. The rubber is anchored to the ground with a stake. The model is pulled back stretching the rubber. When the rubber is fully stretched out the model is released. It is then towed to a height determined by the tow line length. After the apex is reached the model slips off the tow hook and begins its gliding flight. The instructions for setting up the hi-start system, launching the model, and flight trim techniques are covered on the provided kit plan. The adaptation of the hi-start system to hand towing is also covered on the kit plan.
