I use my right thumb and all the coupling goes away

That is fine for just flying around in knife edge. And maybe for knife edge loops.. although harder. But.. when you start doing things like rolling harriers or slow rolling circles.. it is a fight to even do those things let alone get them to look nice, smooth, and even. I guess it depends on what level you want to fly, but, the more advanced you get the more you need the plane to fly right. I am sure if you were good enough you could win the toc with a ucd, but, it is a lot easier if you have the right plane... and even easier still if that plane is set up right. I don't want to even do the toc, but, the point is.. I want to try some of the more difficult moves without fighting it the whole time.

Colby,
If I can get the mixes figured out on my 9C and have enough left I am going to try to couple flapperons to the rudder.
It may be awhile.
I am still trying to work my way thru some of the other stuff.
It's all so new since I've been away from it for over 15 years.
You are right about how severe it is.
Today I put the rudder to it in knife edge and made a conscious effort NOT to correct any coupling.
I think you could just about do a knife edge circle with it and not put any elevator input!
It does so many other things so well it's a shame it's got this one trait.
Oh well...
I guess that's what the computer radios are for!

I have jr, so, will not be of much help to you. On my 9303 I can do the flaperon mixing in that programable mix and set it up on a switch. I can then mix rudder as master and flap as slave. Anyways.. take your time.. plenty of time to mess that stuff up.. ha. I also noticed on some of my other planes with bad ke pitch coupling that statically setting the flaps down made the plane fly better in almost every way including ke. Just hate to do that. I feel like I am "dragging" my ailerons and causing undo stress when I want to do a fast flyby.

So.. to not get off the question.. has anyone tried to use flaps to get rid of the ke pitch coupling.
I got em mixed and they do help. Takes some of the load off the elevator. The elevator mix, although I still do not have it set with the five point mix, just the first of five, as it sits, is situation sensitive. If you hit it just right it works well, but seems to fail out of the correct parameters. I think that is where the five point mix will help, but untill I try it, I won't know.

Getting off the KE subject, my mix is mainly for cross wind landings. The way it couples and dives on KE will give you an idea of the results of a good amount of rudder on landing.

I did the tri stock in the vertical corners above the landing block. Added one more to the horizontal as there is only one across the top of the block from the factory. What made the biggest difference is when I drilled and added one more dowel between the two existing. Now instead of block failure, I'm snapping the tee nuts that hold the gear on. Joe

Joe,
I wish I knew how you guys get tri stock in there.
My fingers are too fat!

I took 4-40 all thread and drilled two holes from just below the wing dowel holes angled to out the bottom channel in the fuse.
I'm not going to get the Good Housekeeping Seal of Approval on this but I then filled it in with a bunch of expoxy.
Don't know if I did myself any good or not.
Time will tell.
Talking about the 5 points...do you have a 9C?

how good you are dosent mean how much work the radio does for you.. granted some people love it that way.. I have been flying that way for 25 years.. i have tried mixing and its just not my thing.. it actually messes with me instead of helping since the feel is not there. I have no problems with slow rolls. and rolling harriers and KE square loops without mixing.. but its all in what you get used to...

No.. didn't say the radio was what made you good. It is all in the shoes actually. I find that no shoes makes my ucd fly much straighter.

You are right.. if you have a plane that flies like crap (not ucd.. just any plane) you don't have to do use mixes or fix it mechanically or any other way. Really don't have to even trim a plane out. it can all be corrected in the sticks. How much you want to correct out by design, mechnical fix, mixing, or just getting a different plane is up to the pilot. Everyone is diff.

That is good that you can do all that really smooth with no mixes. Heck.. it is good that you can do all that period!! You need to get some of that on video. I have not seen a good video with rolling harriers on the ucd yet. I have seen harriers and inverted harriers. A good down on the deck rolling harrier I would love to see. And maybe some good waterfalls.. have not seen that yet either. They usually fall out before the 2nd waterfall. http://www.3dbatix.com/ has some ucd stuff and tulsa3d.com has a cool ucd on floats. Still.. no good rolling harriers!!

I think I am almost have a good rolling harrier after mixing the ke problems out. Flew like a different plane. Just only got 1 flight and it was almost 3 weeks ago.. no time. I did it once, but, might have been fluke.

Default RE: U Can Do 3D

only problem is i robbed my YS 110 off my u-can-do and put it on my showtime and crashed that[&o] I had my high rate switch set up backwards from all my other planes and figured it out after the crash when it didnt respond coming out of a blender because low rates werent enough....

rolling harriers with the UCD are really tricky.. i think they always look sloppy but it will do them.. just not textbook picture perfect.. as for water falls. CHENYs UCD with the floats on them do them better than mine did.. that is kind of the reason i shelved mine for a while and went with the showtime. but now all i have in flying order is my flip 3D.. all the rest of my planes either need work or are being built
My UCD was my most reliable plane and served me for well over 500 flights with all stock hardware... my landing gear block never let loose but it tried.. there are pics of it on my site at at the bottom of my post. just copy paste it there are some under action shots too

My UCD did rolling harriers,a little sloppy but you could recognize it as a rolling harrier. I just ordered another one,been flying my Yak & Showtime but I still miss my UCD.I know I'm going to have to fix the weak areas, but I feel its worth it. At $159 with discount, an old but still running OS 108,have spare HS635's laying around, all i'll need is a receiver&some hinges,&push rods-cant go wrong for the money. I still have not seen any other plane(any size)any pilot, do very high alpha slow KE that the UCD do.I'm going to video it this time before its history.(I've seen other planes do HA KE but not as slow or as HA like the UCD.)Love my Yak,Showtime but the love affair is not over yet with UCD.

MixMaster,
What do you think of the Showtime.
I too have a UCD 60 and think it's a heck of a value!
Thanks!

My UCD .60/YS 110 has been resting for the past two months since I maiden'd my 3W Extra Fun. Come this Sunday, I will pull it out and blow the dust off for an all day fun-fly. I miss flying it. Haven't worked my way up to snap rolls on take off with the Extra like I do with the UCD. Low and snappy. Joe

Havent had but 1 or 2 full flights w/Showtime. Engine trouble,have had a dozen dead sticks without a hitch-lands great dead,keeps the speed up like a pattern plane but not quite as fast. I did try some aerobatics & have added right thrust to the engine.
Heres what I think it does good so far: Elevators-little or no rock,harriers-same,good hoverer, looks like one to bring down low,great knife edge w/o SFG, tracks straight like pattern,very little coupling.With SFG's on, it holds HA KE & slow too but it has a bad tendancy to fall the oposite way you hit rudder. I noticed it sometimes would roll unexpectedly with elevator input,like a high speed tip stall or something-I need many more flights to trim it all out but it looks like a winner so far.

Man joe! how many UCD color Schemes to you have?

My showtime with SFGs i would have to say High A`d the highest and slowest of any plane ive owned (almost a slow sideways hover) Takes alot of stick work to do it that high though. I loved my UCD . Its temperarely retired.

Stoney, you will have the money when you sell that house!

Talking about KE, the Extra Fun KE's unlike anything else. Dump it on its side and the rest is just throttle and rudder. First plane that I could do KE circuits with. Throttle down, rudder up and it will do any angle desired. HA is in slow motion. Getting slower and lower. With time I will see about a full KE loop. Half way there without any roll out, just need more confidence for the bottom half. Joe

We have a guy at our field that does KE circles around the whole perimeter with the UCD 60 with a OS Surpass .91 for power. He is one of those Futaba 9C guys though that won't share his mixes with anyone. He also has the .46 size with an OS four stroke, but not sure what size engine it is. He really likes the smaller plane as compared to the larger brother. He retired the UCD in favor of a Funtana 90 until it was destroyed in a midair and really did not mind the loss. According to him the UCD was a better flier for his preferences.

Now that I have gone to gas I will not look back. When the glow engines planes are gone they are gone. Well O.K., I might keep one or two, but that's it

Joe,
When do you leave for your vacation?

Stoney, the 14th with return on the 24th.

Lee, all I can say is if you fly it, you WILL buy one. I'm that confident. There is only one other with the UL construction out there and that is the Giles 202 UL. Its slightly heavier, 226 sq. in. less in wing area and has reported minor coupling, but comes in at a very close second place. I believe the Extra Fun to be the perfect plane. Its not a looker, but the flight characteristics more than make up for it. Joe

I know what you mean, when my Saito 100 comes back from Horizon I will probably buy the Fliton Extra 330, its just too pretty to pass up and the weight-only 6lbs!!?? If I can keep the 4 planes flying long enough( 68" Yak,Showtime,.60 UCD,Flinton)I'll have enough saved for a gasser, maybe by spring-tax return time(hope my wife doesnt have plans for that money!!)

LOOKS LIKE THIS THREAD IS DYING, I HAVENT LOOKED AT IT SINCE MY LAST REPLY IN OCTOBER AND NOTHING NEW IS IN IT!
I HAVENT FLOWN FOR ABOUT 6 WEEKS DUE TO CRASHING OR DAMAGING EVERYTHING. I GOT THE FIRST FLIGHTS IN TODAY ON U-CAN-DO #2, WHAT A DIFFERENCE A SECOND PLANE CAN MAKE!!!!! THIS ONE HARRIERS NO PROBLEM AT ALL AND I'M TRYING TO FIGURE OUT WHAT THE DIFFERENCES ARE. BOTH OF THEM HOVERED EASY BUT THE DIFFERENCE IN A HARRIER IS REMARKABLE. THE NEW ONE IS 1/2 LB. LIGHTER WITH OS108 AND THE CG IS NOT AS FAR BACK AS THE OLD ONE-ITS SET TO 5.5 IN. BACK WITH THE FUEL TANK OVER CG.THE ONLY MOD THAT IS DIFFERENT IS THE AIL/FLAP THROW, I BEVELED THE TOP OF WING TRAILING EDGES FOR 55-60% UP THROW(FOR UP-RIGHT HARRIERS). I DIDNT USE THE MAXIMUM THROW ON THE FIRST FLIGHTS AND IT STILL HARRIERD OK,WHEN I MIXED IN MAXIMUM UP-THROW THIS THING HARRIERS GREAT,VERY HIGH ALPHA,PROBABLY OVER 45% AND SO SLOW-LOOKS REALLY COOL. iT HOVERS WELL AND STILL DOES THAT VERY HIGH ALPHA KE HARRIER THAT I LOVE DOING,GOES SOOOO SLOW IN THAT ATTITUDE AND IS STEARABLE BEST IF I USE THAT ELEV-FLAP MIX(UP ELEV TO UP FLAPS)
I DISCOVERED A TRICKY WAY TO GET THE MAXIMUM AVAILABLE UP-SPOILERONS MIXED TO ELEVATOR FOR HARRIERS. IF I JUST USED ELEV-FLAP MIXING ALONE, THE FUTABA 9C ONLY HAS A MIX % OF 100%,IT LEAVES A LOT OF AVAILABLE UP-THROW, NOT HIGH ENOUGH FOR MY LIKING SO I ADDED IN 2 MORE P-MIXES TO THE SAME SWITCH, I USED OFSET TO AIL&FLAP(HAVE TO HAVE LINK OFF OR YOU GET AIL DIFFERENTIAL). WHAT THIS DOES IS START OUT WITH SPOILERONS OFSET UP BEFORE YOU APPLY ANY ELEVATOR, THEN WHEN YOU PULL UP, THE ELEV-FLAP MIX KICKS IN AND YOU GET VERY HIGH DEFLECTION ON SPOILERONS.ITS COOL TO BE ABLE TO ASSIGN SO MANY MIXES TO A SWITCH,IVE HAD THE RADIO FOR A YEAR NOW AND STILL HAVE FOUND THINGS THAT I CAN INVENT WITH IT. I MIGHT NEED A RADIO WITH MORE MIXES!!!!!HAVE ALMOST USED THEM ALL UP ON THE 9C!!!!!!!!

FORGOT TO MENTION THE OTHER DIFFERENCES WITH UCD #2, THIS ONE HAS INVERTED ENGINE(OLD UCD WAS SIDE MOUNTED), MANY PAGES BACK SOMEONE MENTIONED THE "WATERLINE CG". I WONDER HOW IMPORTANT THAT IS??? NO WHERE DO YOU SEE MUCH ABOUT THAT BALANCE POINT, BUT IT MAKES LOGICAL SENSE TO ME. IT MIGHT BE SORT OF LIKE A PARASOL WING PLANE, MOST OF THE WATER LINE CG IS BELOW THE WING, MAKING IT SELF RIGHTING. I THINK MY NEW UCD HAS A LOWER WATERLINE CG WITH THE ENGINE INVERTED.IT WOULD BE GOOD TO KNOW IF TRUE, TO GET 3-D IT SEEMS YOU NEED TO SET UP THE PLANE UNLESS THERE IS "ONE" OUT THERE THAT NEEDS NOTHING-I,VE SEEN AND HEARD GOOD THINGS ABOUT THE VISION.

More on the rolling harrier stuff: Mine does really nice, smooth rolling harriers in both directions. Before I was able to do them smoothly, though, I had to mix out KE coupling so that rudder input was true yaw and nothing else. it took lots of time, fixing one thing at a time until it was done. Now, when I feed in rudder during a rolling harrier the rudder input doesnt effect the roll rate, it just holds the nose up. Old story, I know, but mixing out coupling only makes the controls do what they're supposed to do, nothing more. If you haven't spent the hours to learn a good, long, very slow roll no amount of mixing in the world will help your rolling harriers. The UCD is a nice flying fun plane.

Best too all!
Dave
