About this Plan

Questor. Radio control sailplane model.

Quote: "Steve. Please find attached a plan and photo of the Airtronics Questor which I don’t see on your site. The photo is the one I built from their kit in the mid 70’s. It was a good small sport glider for the time. It’s been hanging in my workshop for years. As you can see it is still in excellent shape."

Quote: "Test Report: Airtronics Questor. A Compact, Small Field Sailplane.

The Questor, a compact sized R/C sailplane is the newest design from Airtronics, PO Box 132, Sierra Madre, California 91024. A completely prefabricated kit, the Questor features a 62 in wing span with a total wing area of 409 square inches. The wing utilizes the highly efficient flat bottom E-385 airfoil and is completely built-up. This is an extremely easy wing to build and assembles quite rapidly with or without a dihedral building board or wing jig.

The fuselage is of all balsa construction utilizing sheet sides top and bottom and a pre-shaped balsa hatch which is held in place with keying dowels and a front hold-down screw. The fuselage length is 35 in. The empennage of the Questor features a built-up stabilizer with Warren Truss construction and sheet balsa elevators. The vertical fin is of all balsa construction.

The balsa selection in the Questor kit is of the highest quality, and the plans, as is typical of all Airtronics kits, are quite complete. All balsa parts have been precision machined and totally prefabricated and a complete hardware package is included with the kit. Assembly time of the Questor, ready for finishing, is 6-8 hours. The entire sailplane can be covered with Solarfilm or MonoKote or, alternately, the fuselage can be painted using Hobbypoxy Quick-Prep Resin and Hobbypoxy Quick-Spray, or the fuse-lage may be silked and doped, if you so desire. To save weight, however, we would recommend the use of Solarfilm or MonoKote on at least the wing and horizontal tail surfaces.

The total all-up weight of the Questor is between 15-20 ounces, ready to fly. This little sailplane is highly maneuverable and has quite an amazing speed range. It is equally at home on a Hi-Start or low powered electric winch as well as on the slope. It is designed for individual component 2 channel systems, 2 channel 'bricks,' and has even been flown successfully on rudder only using an Ace Commander single channel system with an Adam's Stomper Actuator.

Price of the Questor is $26.95. We feel that this is an excellent compact sized sailplane that can be easily transported and can be flown from the smallest field. You will find it highly maneuverable, agile, and will even fly inverted. As we mentioned, its speed range is exceptional and its slow flight characteristics are ideal for spot landing events.

The Airtronics Questor has been Tested, and is Approved and Reccomended by R/C Modeler Magazine."

Update 25/10/2020: Added kit review from MAN, February 1974, thanks to RFJ.

* Credit field

The Credit field in the Outerzone database is designed to recognise and credit the hard work done in scanning and digitally cleaning these vintage and old timer model aircraft plans to get them into a usable format. Currently, it is also used to credit people simply for uploading the plan to a forum on the internet. Which is not quite the same thing. This will change soon. Probably.


This model plan (like all plans on Outerzone) is supposedly scaled correctly and supposedly will print out nicely at the right size. But that doesn't always happen. If you are about to start building a model plane using this free plan, you are strongly advised to check the scaling very, very carefully before cutting any balsa wood.
