Ultimate Bipes
Maineflyer:
Look at some of the ads for larger Ultimate kits, such as the ones from the old Ohio R/C. I don't think Ohio is around any longer, but I'm certain that there is someone producing an Ultimate.
Obviously, larger will cost more, but will also fly MUCH better. You may want to contact Horizon Hobbies to see if you can get their Challenger Pitts as an unassembled kit. Change the tail and you have the Ultimate look with a Pitts front end.
World Models (in Livermore, CA) produces a 1.20 size Ultimate ARF that I am currently flying. The difference between this one and the C/G Ultimate is in the cabane and interplane struts. If they would consider selling one of their planes in a kit form, you could make your own cabanes and interplanes and have an Ultimate that flies at least as well as the C/G Ultimate. Since the 1.20 size kit portion of the market is now devoid of the Ultimate kit, you may be able to spark the interest of a manufacturer who already has the tooling working for them
Comparisons at our flying field has mine flying hands down better than the Carl Goldberg. Mine weighs 9 lbs. with fuel and a Saito 1.50GK.
