Ultimate 10-300 (oz5496)
About this Plan
Ultimate 10-300. Radio control scale model for K&B .65 power. Wingspan 54in, area 980sq in, weight 8lb.
Quote: "When Gordon Price is not competing at the World Championships or other full-size aerobatic events, you might find him judging pattern at the Tournament of Champions. Gordon knows high-performance aerobatic airplanes. Feeling that the present crop of competition biplanes could not fully utilize the capabilities of his Ultimate wings he set out to design his own state-of-the-art biplane. With the top model designers he conceived the Ultimate Biplane, at first the 100, then 200, then finally the 300 hp model 10 DASH 300S.
CGP is proud and excited to release Gordon's state-of-the-art biplane as an easy-to-build/exciting-to-fly 'typical' Goldberg kit. We kept the generous moments Gordon designed into the full-size Ultimate for its outstanding performance as he demonstrated at the World Championships. The model outline is quite close to scale with minor changes to improve flying characteristics.
The kit is designed around the proven 'slot-tab' method of construction, so you will find this the 'Ultimately-easiest' biplane to build. Simple built-in fixtures assure warp-free wing assembly. All screws, hardware (including glass-filled engine mounts) etc are included to finish the airframe.
Formed bolt together aluminum cabanes deliver precise 'hassle-free' wing alignment. Full-size plans, and clearly photographed instructions guide you through every step. Also furnished are rugged molded Cowl, Canopy, and wheel pants and two large sheets of full-color decals for the finishing touches of your Ultimate model..."
Discontinued kit from Carl Goldberg Models ref K-53.

Quote: "Good day, Attached you can find plans and traces of formers and ribs for the Carl Goldberg Ultimate Biplane. These files were shared today on FB group 'Balsa Model Aircraft Builders Association' by user Matt Newman, who posted: '... some time ago there was an effort we did on RCUniverse to document and produce a complete set of plans for the CG Ultimate. This includes formers and templates for all the die cut parts'.
He mentions he can take only partial credit since there were several persons involved. So, here are the files. Plans already in OZ have better resolution than the ones attached. I just wanted to include the whole package. Regards,"

ScaleType: This (oz5496) is a scale plan. Where possible we link scale plans to Wikipedia, using a text string called ScaleType.
If we got this right, you now have a couple of direct links (above) to 1. see the Wikipedia page, and 2. search Oz for more plans of this type. If we didn't, then see below.
Notes:
ScaleType is formed from the last part of the Wikipedia page address, which here is https://en.wikipedia.org/wiki/Ultimate_Aircraft_10_Dash
Wikipedia page addresses may well change over time.
For more obscure types, there currently will be no Wiki page found. We tag these cases as ScaleType = NotFound. These will change over time.
Corrections? Use the correction form to tell us the new/better ScaleType link we should be using. Thanks.

On the plan, it misses the frames of the fuselage.anon - 17/03/2019
Have added the manual, which on page 4 includes a parts identification sheet. So that might be some help. But no, the fuselage formers are not shown on the plan.

Like most Goldberg kits you have a top and side view to take measurements and make formers.

The parts cutouts are missing parts from die sheet 5316, PT #3468 (wing joiners and plates.) The parts cutouts is also missing the forward turtle deck sheeting. This sheeting is where the cabanes come through.

Pay attention to the size of the wing strut in the part drawing. It is longer than the strut on the print. I neglected to verify this part against the print and struggled to mate the wings to the cabanes until I checked.

If you build it put the brace wires on the tail like the full size Ultimate. I belonged to the Channel Island Condors R/C club in the early 90's and there was at least a dozen Ultimate's flying at any one time with everything from a glow .60 up to the hottest 4 stroke 1.20 available and at least one glow .90. It was found that the tail would crack when you threw it around hard, the bracing stopped that.

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.
