Bob,
You need to use safety wire to keep the turn buckles from loosening up. Your favorite hobby shop should have some.

thanks for the suggestion about safety wire. After actually nearly giving myself a heat-stroke trying to assemble this S.O.B. with the "stock" wires and turnbuckles, I've copied Francis' hose clamp idea, with a couple of mods.

I have always believed an airplane that takes longer to put together than the first flight lasts is an airplane that needs redesign. This one, with it's turnbuckles, is just absolutely the WORST.

So I have "new" wires, and they attach to the interplane strut "pins" using Sullivan flying wire strap/ends, then are looped through my "hose clamp" adjusters. I made them similarly to Francis, silver-brazed hook eyes on the screw parts. Ain't real pretty, but takes all of ten minutes to do now.

Way better.

(Also now understand why we didn't hear much about this bird.... and why AW would have dropped it like a hot potato. There are WAY easier ways to design things.)

I am, of course, very hopeful that it will fly SO well that it will make up for all this b.s.

P.S. - You should note the bottom wing is 3/4" longer in span (per panel) than the top wing. I asked World Models about this, and they said "yes, that is the way it is supposed to be". If anything, a bipe should always have the TOP wing with larger area, NOT the bottom one. My own opinion on this is that it was a "oops", and rather than fix it, they just pressed ahead. Another reason that we probably haven't heard much of this bird.

Hi Guys

I would like to know what throw settings would be the best for the initial triming of the model.

The model is now ready for it's fist engine start up.

Today we have been balanceing the model it only required 400g of lead to balance it out. Quite suprised on this as you well know we have the Ultimate with a ZDZ80RV-J which she whight 1kilo les than the average 100cc twin.
We have decided to place the CG just behind the top wing tubing. More or less about 5" 3/4 inches from the leading edge.

I know that there has been lost of descussion on the Ultimates CG but i have not seen any Videos or facts to confirme the correct CG,
Good question would be is the WM Ultimate the same as the Aeroworks Ultimate CG.

My research has supported the idea that the AW *is* the World Models, so I'm going with that. IN fact, mine *was* an Aeroworks kit, and I completed all the assembly using the World Models online 33% manual. Everything was the same, parts labels, shapes, measurements, all of it.

The CG of 5 3/4" is probably very good. That's where I'm at, and I had to move my two of my A123-2300 packs to the engine box to get there.

I also setup all travels per the manual. Rudd 85mm, elev 20mm, ailerons 30mm. That's what I set for my LOW rates.... so that I have a lot more if needed.

Francis - your finish and color scheme is just beautiful. VERY good looking, and far, far better than the stock ugly World Models schemes. You have done a terrific job with it!!!!!!!

Probably. Depends on several things; I still have an interplane strut to plug and re-drill because of the incidence jigs being off, and some final tweaks on wires/hatch, etc. Recheck of servo programming, etc. You know.
I'd also prefer more runway and less muddy ruts....
Mainly depends on the steenkin' weather....

Hi Bob

Thanks for the complement, glad to read that you like it so much.
Well I have just started the ZDZ 80 RV-J for the first time. It sounds fantastic.

I have measured the top and bottom wing span, and as you well said, the bottom has a bigger span than the top.

The Top measures 76 1/4"

and the Bottom measures 78 1/2"
