Last trial fit of wings and re measure all distances (wing tips to tail fin etc) All are accurate to 2mm.
Incidence is 0 degrees for both main wings and +1.5 degrees at the stab.
Finally completed both struts (lots of sanding and eyeballing) thumb screw anchoring, 3mm carbon alignment pins.
The struts perfectly follow the contour of the airfoil, this along with the wood saddle on the alu cabanes ensures a snug fit of the top wing at the desired incidence.
I am starting to run out of excuses to start the covering……………..

The wings when assembled are so sturdy you could probably fly them without the fuselage

Dreaming up colour schemes has never been my strong point so I had a look in my left-over’s bin and saw I had a supply of Circus Pink and white Super Monokote also some checker black and white.
I have made a feeble attempt to see how this may all go together on an Ultimate by colouring this three view.

Stab glued and waiting for the epoxy.
Tomorrow the fin and turtledeck...
...summer break is coming in february, I have to hurry now!


+1-1/4 degrees incidence, as shown on plans... ...had to sand some to get it square and true!!
I finally stopped borrowing a friend's incidnce meter, and bought a shiny new Robart one!
Very nice and smooth action BTW.

Would love to join the brotherhood! Flew my Ultimate kit I built 15 years ago for the first time last summer. I also have 1 other kit built plane and 2 ARF versions. One ARF is in need of some good repair that I will hopefully get to soon.

mnmopar, Welcome to our great brotherhood, your number is 97, I hope you can find here great ideas for your repairs and get your Ultimate in the air in a snap, it would be great too if you decide to share photos or new ideas on the process.

Make this kitnumber 98 for the brotherhood

My father picked up a bunch of gear from an estate sale of an old bloke who had been flying RCsince the 40's.

One of the non-descriptboxes contained an Ultimate 10-300 kit, not thatwehad any idea whatthe kit wasuntil Google was consulted, then I found this thread.

It will be a few months before the kit is started, we have a couple of other projects that need finishing first.

I have one to sell, I'd sold it to a guy in Austrailia but the shipping cost killed the deal.

I'll relist it in the classifieds if you're interested. It is a fixer upper.

I also have a Kit very much like trippergreenfeet's dads,, Original box is gone because it was water damaged, some slight warping of parts but still buildable, just might take some special care. I had bought it for a buddy to replace his crashed bird, but he like me has moved on to larger birds.

Hi Jon, always great to read your lines, no plans by now either way I am so happy to be part of your original idea and have the support and friendship of people like you. Our brotherhood has become a success thanks to people that have been posting bulging and repairing threads.

Hey all, I'd like to apply for membership. This is my second CG Ultimate. Unfortunatly the first rekitted some years ago.
I built this one when a few of our club members got together for a building session. We built 4 or 5 that winter. I converted mine to electric and couldn't be happier!

I'm using a turnigy 50-65 380Kv / 1820w motor 5000mah 6cell, 90 amp speed controller and an APC 18x10 prop.
Flight times aren't bad, has plenty of power (cruises about nicely at 1/4 throttle)

Thanks! This was my first real electric project. Before that it was a few foamies etc. However I have to say flying E isn't as "green" as some would say. I go to a lot of area gatherings during the summer and usually burn 5 or more gallons of gas running the generator to charge all the batteries... ok so some of it for the ac in the camper...

I did have one interesting flight though... I originally planned on 2 6cell packs in parallel to balance where shown on the plans. Well a few of the guys tried to convince me that I didn't need to run 2 packs. In a moment of weakness I gave in. I had the packs held on the bottom of what is usually the platform that holds the fuel tank by a piece of wood that I screw down to a couple of posts attached to the fueslage. I took one pack out, moved the other as far forward as I could... which wasn't much... then strapped it in with velcro.
I took off expecting it to be a bit tail heavy, but every thing seemed fine when it left the ground. I climbed out, made a turn, flew down wind, made a turn back towards the runway. It was at this point I saw a rather large object leaving the plane.
I right away recognized it as being my battery pack, with platform and velcro still attached!
My first thought... foolishly I guess... was that it was going to be REALLY tail heavy now. Well the plane was gliding pretty well. I made a turn to the left to get it over the runway, followed by a turn to the right to line it up, followed by a slick touch down.
One of my buddies at this point yelled to me that it was a good thing I had a separate pack for the reciever...well... err.. no, I didn't! That 18" prop swinging in the wind managed to turn the motor into a generator and sent enough back to the reciever to power everything! I was glad it didn't occur to me that it shouldn't be working while I was trying to land it!
