Tiger 60 (oz11032)
About this Plan
Goldberg Tiger 60. Radio control sport model. Wingspan 70 in, wing area 855 sq in, for .45 to .65 two cycle or .65 to .80 four cycle engines.
Discontinued kit from Carl Goldberg Models.
Note this here is a modern redrawn plan in PDFvector format. For a scan of the printed plan as supplied in the kit, see Tiger 60 (oz11632)
Quote: "The new TIGER 60 offers the latest in aerodynamic technology in a great-looking aircraft. With its light loadings, low landing speeds, and tricycle landing gear, the TIGER 60 makes a deluxe low-wing trainer. Yet, those same features; along with its long tail moment and clean, symmetrical airfoil come through with super smooth aerobatic performance. Loops, square loops, and cuban eights groove perfectly, rolls are on-a-wire axial, and inverted flight couldn't be easier. Plus, all you really need for truly sparkling performance is a .60 to .65 two-cycle. Anything bigger would simply be excessive.
Before you start, please read through these instructions and review the plans to become familiar with the TIGER 60 methods of assembly. Having said this, we hope you enjoy your new TIGER 60 as much as we have. It has become one of our favorite aircraft to fly..."

Update 28/01/2021: Replaced this plan (also the CAD file) with a revised version, thanks to AlanSinclair.
Quote: "Hello, I discovered additional errors in the Tiger 60 while working on drawings for the Tiger 2... Here are the updated files. Have a great day."
Update 11/02/2021: Added 'tools' supplement file, showing the wooden tool/jig parts that were supplied with the kit, thanks to AlanSinclair.
Quote: "Here are Tools & dihedral jig for the Tiger 60 (as was pointed out in one of the comments). I managed to buy a partial Tiger 2 kit with the plans, so I was able to duplicate the 'Tools' for the 60."

User commentsA helpful hint for builders of the GREAT Tiger 60... An otherwise great design had one structural flaw/weekness. The tail assembly (empennage) is of fairly large surface area, and the cross-section of the fuselage immediately ahead of the tail was small enough that Tiger 60's would suffer from "tail wiggle". This can be demonstrated by "dangling" the entire plane from the tail. Hold the plane, fuselage down - with the wing on - with one hand on each stab. Hold the plane with the bottom of the fuse facing you. Rock/twist the entire plane gently from side to side, looking at the last open "bay" on the bottom of the fuselage as to twist/ Rock the fuse. You will see the covering on this bottom bay "oil-can" as the fuselage flexes at its narrowest point. This manifests itself as "tail wiggle" in abrupt aerobatic maneuvers. Fortunately the fix is super easy: When assembling the kit, just don't "punch out" the last bay on the bottom of the fuselage. Instead permanently glue-in-place the "punch-out" into the last bay (narrowest one at the rear) of the bottom of the fuselage. In the kit instruction book this is "lite-ply" piece PT # 3902, D/C SHT. 6803. For scratch/plan builders, just don't cut out the bottom bay (at the rear) of the fuselage - presto! No more tail wiggle. You will LOVE the Tiger 60, it flies GREAT... it "grooves/tracks" like a slot-car.

Built in winter of 2006/7 maiden in 2007 - O.S. Max Surpass .72 4-Stroke - 38 flights it Flew GREAT [more pics 004].

Great effort! I did not see the vitally important wing dihedral support parts on the cut sheet, see manual page 14, step 15 for their assembly. The wing plan has leader with reference at the wing leading edge tip dihedral support location but is missing the forward pad alignment box as shown on the original plan, see manual page 15, step 15 for their placement. Not overly a big deal as long as the base of the support at the wing trailing edge is properly pinned and kept squared to the wing. I also did not see the wing spar set-back gauge on the cut sheet. The wing top spar set-back gauge helps with offsetting the top spar needed when wing halves are joined, see manual page 13, step 8 for its usage.

* 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.
