RE: The Big Blue 260
Steve or anyone using a Pull Pull rudder set up,
I'm building the 260 with a ZDZ80 and was wondering how you set up the pull pull rudder. Using the 3" arm that came with the WH hardware kit, it looks like I will have to cross the pull pull wires to prevent interference with a bulkhead. But, if I set up the Dubro 882 control horn to pivot at the hinge line and be 3" apart, I only get but about 35 degrees of rudder swing before the horn contacts the fuse. I'm guessing I'll need a 3.5 or 4" horn spread, with pivot on the hinge line, in order to get a 45 degree throw. So the 3" arm will not be useable.
What is the size of your rudder tiller & servo arm? and what rudder throw do you get?
If crossing the wires are you using an offset servo arm or straight?
Thanks for any advice or photos.

RE: The Big Blue 260
Ok, you guys convinced me to get a Wild Hare 260. But first, I gotta get rid of the H9 Extra 260. So if you know anyone looking for one, tell them to hit me up. And yes, I'll put a classified ad in as soon as I get down to Littleton to pick it up from my uncles house. But if you guys want the details for your friend, PM me.
Oh, and I have another question. If I put the new 3W 80 in it (5 lbs.), could I still get it to balance with a pull-pull system on the rudder?

RE: The Big Blue 260
Hawk, I set mine up like this. The bell crank arm is 4 inch, the wires are not crossed & I used a piece of 3.5" all thread for the rudder arm. With the WH arm the wires hit the back of the cutout if they were straightn the front of it if they were crossed. Might have something to do with the placement of the tray, I dunno. I get mad throw with this setup. 1/4" from the elevators at full deflection. I never measured it but thats what it is. You could probably do with just one servo, but I like redundancy & authority.
By the way, the plane wound up at 20lbs 2 oz. & that is with a nearly full tank of fuel. We measured it today at the airshow with digital scales.

RE: The Big Blue 260
I would Steve but I dont have anything to haul planes in. Also want to check the weight on that plane.
Kent
Jamie got the gear fixed, looks like a big ole scab of bubble gum. He HE He[:'(][:'(]

RE: The Big Blue 260
It does fun tumbles also 
The thing that blew my mind was how slow I could perform moves like rolls and knife edges. I can do most of my flying at about a quarter throttle!

RE: The Big Blue 260
Thanks Steve for the photo.
However, I don't see how I can use the 4" arm and 3.5" rudder tiller size like yours with out it rubbing the bulkhead just in front of the wire exit slot. The slots in my fuse might be in a different location. I have a bulkhead just at the H Stab leading edge and the wire exit slot begins 1/2 inch in front of this bulkhead. Looks like I will need to extend the slot up to the bulkhead or through it, and if I don't cross wires then I will have to trim off the inside of the bulkhead just in front of the slot. I'm using a 4" all thread tiller (came with the WH kit), but the max pivot point spread is 3 5/8 in after adding the Dubro horns. Seems like the instruction manual would give you some direction.

RE: The Big Blue 260
20lbs....dont make me jealous 
Oh well back to the drawing boards. Believe it or not when it gets windy in FL I consider adding weight on the big planes.

RE: The Big Blue 260
Yeah, I don't try to make 'em light, just always do what I think needs doin'. When I ad the wheel pants & get the gaps sealed that will add a few oz. Finally get the spinner mounted, that will add a few more oz. The big one is going to be the smoke system. That is going to be good for about a lb. & a half. I'm guessin' the final flying weight is going to be about 22 lbs.
I think I am going to go back to just flying for my own enjoyment. I flew that airshow on Sat. & there was a 15mph crosswind on the runway, 90 degrees to the runway as a matter of fact. I didn't have any problem with flying although some of the manuvers looked kinda bad, landing wasn't to bad either. Problem was when it came to taxiing back. The wind was strong enough that I couldn't keep her in a straight line. What got me was the fact that they (airshow organizers) were all hot to get us there & then kept changine the schedule. One of the other guys had radio issues, another guy wouldn't fly because of the wind, it was just a mess. I don't need the aggravition. I enjoyed the applause & the people coming up and telling me how much they appreciated the flying but I think I would rather just fly for myself. Ya know what I mean? Never mind feeling like you are obligated to fly. I mean face it. Who wants to fly a basically new plane in a strong crosswind in front of a couple of thousand people? [&o]

RE: The Big Blue 260
It's interesting with the amount of work that people put into some airplanes to make them light while others try to make them heavier. Don't get me wrong, I've seen what happens when you have a little wind and a really light wing loading. Gotta get them into a certain range to where they land nicely (i.e. they're not a brick) but still have enough weight to penetrate.

RE: The Big Blue 260
The wind doenst bother me much, but the flu sure does! I wont fly again for the next week or so until I get better. Still, you can only fly a SIM so much and not get borred.
No I feel you, I love the days when its just a few guys out there and you can just have a good time. Slightly bending the rules seems to be when I will try some new crazy things. I am trying to perfect figure 8 rolling circles right now! I actually have to change from thumb flying on my left hand though otherwise my thumb gets tired about half way through.

I went with 5945 servos on the ailerons, should have went with the 5925s, the 5945s are too slow for my liking. Either has enough torque for the plane & the 5925s are much faster. 1/3rd scale planes are slower to respond then little stuff but sometimes you want all the speed you can get. Makes things like 4 point rolls much cleaner & transitions from inverted flat spins to upright spins, things like that.

RE: The Big Blue 260
Just dont do 5925's on rudder. I learned that lesson the hard way. Luckily my plane just died about 10 seconds after I landed...what luck!
I have to side with you on that. Eventually I'll swap my 5945's for 5925 - or just rebuild them as 5925's. Thats the cheaper way to do it. Although servocity has a 20% off servo sale right now.

RE: The Big Blue 260
airborne just send the striped 5925's to hitec and state that you want the gears replaced with 5945's because they better fit your application. They will do it for free and even replace the decals.
