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 is a modern redrawn plan in PDFvector format.

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.

Direct submission to Outerzone.

Update 5/6/2022: Added kit review from Model Builder, March 1995, thanks to rocketpilot.

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..."

Dear Outerzone Administrators, Thank you so much for curating and maintaining this fabulous repository of all the classic and old school RC-airplane plans and articles. I hope your eagerness and motivation will continue to keep this website around for years to come!
I would like to offer to share on your site, photos of my built Goldberg Tiger 2 [pics 004-007]. My admiration of RC-airplanes are the classic looking sport and pattern airplanes of the 1980s and 1990s. I built this last year from a kit that I was lucky to buy from someone in the US and it continues to be a fun and smooth flying airplane. Obviously, I made some modifications, the most obvious is the conversion to a tail-dragger (conventional) landing gear setup. Not so obvious are the slight enlargement of the rudder and a very reduced dihedral. The spirit of it being, that I wanted it to resemble a 1980s/90s pattern aerobatic airplane you would back in the days of glow engine fun-fly gatherings. It does some pattern aerobatics quite well and I think it looks sharp, for a boxy fuselage airplane.
Have a wonderful spring and keep on flying! Best Regards, from Montreal,

What engine? I see 2T engine, but CC? I love Glow engines! Thanks,

The engine installed is an OS 0.46 AXII engine (7.5cc), with a 12x4 propeller.

Hi, Hereby a few pictures of my Carl Goldberg Tiger II build from this plan [pics 008-013]. Powered by a 7.5cc Super Tigre two-stroke engine. Build log at a dutch forum see: https://www.modelbouwforum.nl/threads/club-bouwproject-ornithos-tiger-2.246723/ Cheers,

Notes

* 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.

Scaling

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.
