Griffin III (oz9894)

About this Plan

Griffin III. Radio control model for Cannon radio gear. Wingspan 28in. Wing area 120 sq in. Weight 11.5 oz.

The Griffin III (wingspan 28in) and Griffin VI (wingspan 36in) were both the subject of an article in Model Builder, Dec 1982.

Quote: "By BILL CANNON ... A two-for-one construction article for a couple of very spry, pocked sized, full-house R/C sport aircraft. Full size plans are available for both sizes, though only one plan is shown here.

These .03 and .061 Griffin Models offer something a little different for small aircraft buffs. Different only in size (and weight), both models provide outstanding performance for their engine displacements. Engines specifically recommended are the G-Mark .03 R/C and .061 R/C, both of which are equipped with throttles and mufflers and are ideal for R/C applications. Other small engines may be used, but with some loss in versatility.

Wind penetration for both models is excellent, and with all four channels of control plus steerable nose gear, both fly and handle much the same as larger pattern ships.

Although not beginners' aircraft, both the Griffin III and Griffin VI are relatively easy to build and fly. Speed is great enough to insure full control even in windy or gusty conditions, and for performance of practically all maneuvers you might wish to try. Built-in wing tip washout is largely responsible for the unusual stability of both aircraft.

Plans include details of a full, four-channel installation using the Cannon Super-Micro System. Two or three-channel versions can be built by making minor plans modifications. For rudder control, without ailerons, we recommend that you double the amount of wing dihedral shown. Be careful to maintain the balance at the point shown. Radios other than the Super-Micro may be used, but be careful to keep the flying weight within 10% of that recommended or performance will suffer.

Separate plans are available for both the Griffin III or Griffin VI, so take your choice or try 'em both. Neither one will disappoint you. Instructions herein are generalized to be applicable to both versions of the Griffin. Where significant differences occur, they are noted in the text. Otherwise, the individual plans provide specific details as required..."

Quote: "For many years Cannon Radios were the only real choice for very small RC airplanes, other than rudder only or galloping ghost setups. The Cannonshot (oz1247) and Cannonball (oz4406) are two plans you list that refer to this prior reality."
