RE: Carl Goldberg Ultimate 10-300 Brotherhood.
Hello all, I would like to be a member of the brotherhood, I acquired my ultimate last year and its been a fun to fly. I also have a question for the brotherhood. I did not build the ultimate i have but did acquire a kit to build some time down the line it has to get in line. Anyway the ultimate was built with a Y pushrod for the elevator and pull pull on the rudder. When i pull back hard on the elevator i notice a that it also rolls when this is done. When i get it up on the bench and checked the deflections i notice that when fully deflected one half moves more then another in the order of a degree. This is usually not a problem until i start to really push the plane around. I know i can mix it out with the radio but i don't really want to do that. No real reason i just don't. So i think my two options are to add a addition servo and have a dedicated pushrod for each elevator half. Or set up a pull pull on the elevator using one servo. I have a couple of ideas on how to do a pull pull but was wondering if anyone has any suggestions or pictures?<div>

RE: Carl Goldberg Ultimate 10-300 Brotherhood.
Tom,
I am assembling a warbird that has pull-pull for the elevator, the stock set-up. Most guys on that thread for that plane are recommending against going pull-pull on an elevator. I am going to go with a rigid control rod on that one. I just haven't seen pull-pull used on elevator even once, but that doesn't mean it won't work. I guess I am saying try it if you are comfortable, but I wouldn't myself, lol. Regarding the elevator halves, I have the old kit version and have the Y control rods to the elevator halves. I don't notice any difference in throw on each half. Perhaps your rods are not stiff enough. I would not try to mix in aileron or rudder to counteract that difference in elevator throw. Either stiffen the Y control rod using one servo, or go to 2 elevator servos with preferably short control linkages. Jon

Hello all, I would like to be a member of the brotherhood, I acquired my ultimate last year and its been a fun to fly. I also have a question for the brotherhood. I did not build the ultimate i have but did acquire a kit to build some time down the line it has to get in line. Anyway the ultimate was built with a Y pushrod for the elevator and pull pull on the rudder. When i pull back hard on the elevator i notice a that it also rolls when this is done. When i get it up on the bench and checked the deflections i notice that when fully deflected one half moves more then another in the order of a degree. This is usually not a problem until i start to really push the plane around. I know i can mix it out with the radio but i don't really want to do that. No real reason i just don't. So i think my two options are to add a addition servo and have a dedicated pushrod for each elevator half. Or set up a pull pull on the elevator using one servo. I have a couple of ideas on how to do a pull pull but was wondering if anyone has any suggestions or pictures?<div>

I have two servos placed at rear of the fuse, they work great, the links are short and very reliable, I used my computer radio to mix both servos and deflect identically, some servos even the same brand work different and may deflect a bit different causing an unexpected roll or dirty flying. By mixing the servos the deflection of elevators can be matched and have a real sweet performance.
On the other hand, if you do not want to make drastic changes, you could stiffen the pushrods, just like Jon said, they should work fine, as you are using only one servo and the deflection would be the the same if the pushrods and Y are made with the same distances.
Enjoy.

Hello Gentlemen,
I just bought the CG 60.5" Ultimate. Am I allowed into this thread or is this only for the 30%?

I did some cosmetic work on my bipe. Wow, I just realized how sexy the ultimate looks. Added a pilot and instrument panel, checkered wing tips, and some stars. She looks like a beaut! Pics coming soon.

I live in Australia and want to sell my CG Ultimate, I have a Saito 120 in it and it is awesome. I'm selling it otherwise I would of hung it from the ceiling in the hobby room. The wife said to sell it if I'm not going to fly it anymore, fair enough I reckon.

Hey guys. Building a new one to rplace a crashed one. Any suggestions on the back turtle deck. I wet the 1/32 ply and it still cracked at the fin. Thought of running a few stringers and balsa sheet it.

RE: Carl Goldberg Ultimate 10-300 Brotherhood.
callide, I think this situation calls on you to exercise your powers as COMMANDER IN CHIEF. Inform the minister you will be keeping the Ultimate and getting the corsair. You know after you fly the Corsair the awesomeness of your Ultimates abilitys will give you an overpowering need to have it back. So let the minister know how much it will save in the future. If that doesn't work, hide it!

A lucky man am I. My wife supports my hobby. I can have more than one plane at a time. Actually I'm up to about 12 at last count with the assorted unbuilt kits and ARFs thrown in. You could tell het the alternative is the bar - or worse GOLF!

RE: Carl Goldberg Ultimate 10-300 Brotherhood.
Hello All,
I'm planning to maiden my Ultimate tomorrow. Any suggestions?
Some details, I bought it used, so it's flown before, but tomorrow will be first flight by me. The rx is new so it will have to be re-trimmed. I had added a fairly heavy pilot, which since it sits way aft of the CG, caused the plane to be a tad tail heavy. However, I moved the rx battery from behind the throttle servo to under the fuel tank, which has the CG now perfectly at the recommended 60mm from LE. I added 40% expo to all surfaces. Throws are around 35 degrees on high rates, which is significantly greater than the ones mentioned in the manual (which prescribes a max of only 14 degrees). They are lowered to 75% on low rates (so around 26 degrees). This is the 60.5" wingspan ARF, AUW is roughly 12lbs, engine is OS160 two stroke, 16x10 prop, 20oz tank.
Would appreciate all suggestions, particularly those related to throws/handling and landing (hot/fast?). Thanks.

Ultimate is back in work. It will be powered by a Hacker 50-16L, CC 100 ICE and, 8s-4000. I'm just going to call it the Clorex Ultimate. It will fly crisp and clean lines!!!
