Tiger 2 (oz12821)

About this Plan

Tiger 2. Radio control sport model. Wingspan 61 in, wing area 680 sq in. For .35 to .46 2-cycle or .40 to .50 4-cycle engines.

Discontinued kit from Carl Goldberg Models.

Quote: "The TIGER 2 is a new breed of cat - one that has evolved from what many of you knew as the Sky Tiger (oz10303). This 90's generation aircraft has what it takes to be a good first, low-wing subject, as well as a reliable sport plane. The construction is true-to-form Goldberg, a standard of the industry, engineered for the novice builder with 'top gun' performance in his sights.

The sure-footed tracking of the take-offs and landings will make your airborne transitions as graceful as the maneuvers in between. And speaking of maneuvers, the TIGER 2 does them all: super smooth loops, four-points, on-a-wire axial rolls and ...oooh... inverted flight.

So, let's get going! But before you lose yourself in the joys of building, do a read-through of these instructions and look at the plans. We're sure that you will find building and flying the TIGER 2 absolutely Grrrrrrrreat!"

Note this redrawn plan is complete, in a way that the kit plan never was. The kit plan did not show all parts and tools/jigs etc.

Quote: "Review By David M Sanders. The Tiger 2 from Carl Goldberg Models.

A Tiger that's easy to tame and playful as a kitten is how the designers characterize this trike-geared low-winger, and as our reviewer discovered, it's an apt description.

A low-stress plane of decent size and capable of good aerobatic performance is something I've wanted for a long time. Goldberg's Tiger 2 is a bird that has it all - easy construction, good geometry, sensible power requirements, the sexiness of a low-wing design and a sharp, non-trainer look.

The kit: Everything comes neatly packed with all hardware and small wood components in sealed poly bags. Closer inspection revealed very high quality balsa and ply materials, many of which are pre-shaped. Included in the kit are a very complete hard-ware package, pre-formed wire landing gear and a universal-type engine mount. About the only items necessary to complete the airframe are wheels, engine and fuel system.

Also supplied are a very detailed 31-page instruction manual and a 19-page general information booklet with instructions relevant to adhesives, covering, radio setup, pre-flight procedures and even basic aerobatics. Having become used to rolled plans in kits, I was a bit disappointed to find folded plans in this one and had to iron out the creases before I could start building.

Construction: The empennage is of lightweight built-up truss construction; as the Tiger 2 has a fairly long tail moment, this makes a lot of sense, besides being typically Goldberg. Parts fit was very good with the exception of the stabilizer doubler, which required significant trimming. I was careful to use the stiffest pieces of wood for the stab and fin trailing edges, which would later receive the control surface hinges. A nice feature was the supplied sanding jigs for beveling the control surfaces and rounding the leading edges, which will save a novice builder lots of frustration.

The wing features a symmetrical airfoil. To enable building it on a flat board, the designers conceived an effective method of built-in jigging using 'tabbed' ribs, three on each wing panel. The tabs act as stand-offs from the bench to insure parallel alignment of the spars and leading and trailing edges. The wing is constructed upside down directly over the plan.

The 3/8-inch square basswood main spars in my kit were slightly bowed (as wood is wont to do), so be sure to lay the flattest surface against the bench..."
