Welcome thirsty003. I hope you enjoy your plane and this forum. Good looking job on your build. On your question about lateral balance, I recommend you balance by adding wing tip weight. I feel it really improves the way the plane flys. This is especially true in hover and other stalled manuevers. I balance mine by hanging from the ceiling with thread on the tail wheel and a small nail I mount (just for this purpose) at the center of the firewall on underneath side. I hang the plane upside down for this exercise. I only had to add a very small amont of weight to mine. I took finish nails and coated them in epoxy glue and drilled small holes in wing tip and pushed them in. They never move. On another plane I had to add about a 1/2 oz to balance. On that one I epoxy glued the weight (flat stick on type) and then put a patch of monokote over it. Stays very nicely and all you see is a buldge where the monokote is.
My CG is at 5 3/4". For me this is just about perfect. I can land easily and still do a rising flat spin. You can't do either well without a perfect CG. This plane is very forgiving on CG. It can have the most variance of any plane I've flown.
Be careful. These planes tend to crash.
Thanks,
Barry

Another thing I do to laterally balance to help in not adding much extra weight, is to mount the battery on edge, upright, on the side of the fuse that needs the weight. The battery is heavy an even though it dosen't usually stop the requirement to add wing tip weight it reduces the amount needed. Good luck.
Thanks,
Barry

thirsty003... On my weights, I had the stick-on weights at 1/4 ea.
I think I used under 1/2 oz... I balance mine almost like Barry, But
I do it up right, I have a screw on the firewall and this may not be
good, but it has worked for me so far.. I just put the kevlar<sp>
stunt kite string on the rudder hinge.. The string is about 4' or so
with a sliding loop at both ends, I set the plane on the garage floor,
doors closed and lift it for a second and add weight to what ever wing
needs it and lift again until both wheels set down at the same time
make my small cut it the bottom of the wing and epoxy in and re-
cover... I'm sure you have your own way.. It all works... And it does
make a difference....

Gary.... Great weather.... Thanks keep sending it over:-) My brain
timer is working a little better... No out of fuel deadsticks the last
two days:-)))) But it's kinda a off and on thing:-(

ok, i know all you guys are Futauba guys(most of you) im thinking of converting, is this what i want?[&:]

Thanks guys

^ Well if your willing to splurge a little more, you can get the 14 channel computer color screen radio (for around $2000 bucks for transmitter only!). But yeah that's a really good raido, anything with elecrtonic trims is nice. I would get it if I were you... I have a T6XAS and the only thing I don't like are the trims (manual, but the "servo saver" confuses me so I have to trim out every airplane I fly with it).

BTW, the maiden with the .91 in the nose was AMAZING!!!! It fly's so well and doesnt even act over powered! My new favorite airplane. All I need to do is fine tune the engine and she'll hover no problem! I tried today, but wasn't comfortable enough with the plane yet. But vertical take off's are no my favorite way showing off. There was some guy with a .46 on his UCD today and you could tell the difference in all over preformance.

Colin"Addicted to U"C

i thought you would like that 91 preditor 500, if the cg on the plane is ok and the engine dont weigh to much i cant see whats wrong with going with power, it saves you fuel(didnt you use less than normal) and its great for vert pull out. you dont fly around full throttle all the time and use it only when you need it and you cant beat it, its greati love my 100 in my 46[X(] i flew today and got my hovers up to about a minute and i do believe the 46 hovers easier than the 60 size(especially with this engine)
i dont know if i have enough brain cells left to program a 14 channel, i might be pushing it with a 9 channel, but i think ill like this 9cap, everyone else does here, sooooooooo ill try it, these guys are right about everything
glad you had a good day, so did i[sm=thumbup.gif]

Gjeffers, I'll have to say I love my 9C. It's just perfect. I wish I had splurged and bought it originally. Now I have a couple of other radios that I'll have to put up on Ebay.....[]

Man am I bummed....... it sounds like lots of you got to fly this weekend and not a chance here. It's raining cats and dogs here today. That's the problem with this part of the country. One day you're sweating to death and the next day you're soaking wet.........[:@]

predator500, congrats on the maiden of your 91 UCD..........[8D]

gjeffers, Here is the radio you want, I think. It is the latest version of the Cap. It's called a "super". Also it has the PCM reciever. From the other post I have out on this subject people as saying it has less tendency to glitches. http://www2.towerhobbies.com/cgi-bin...I=LXHMD2**&P=0
Thanks,
Barry

gjeffers, I don't know exactly what the differences are between the Super and the regular Cap. Mine is the regular old style and I like it. But if you are buying a new radio then I would get the latest.

Speaking of that, tomorrow I'm gonna go get me a digital camera. But I need some help. Once I have the pictures on the camera how do I upload them on here? I hear you have to shrink the file size or something. Man I know nothing about that. Please help.
Thanks,
Barry

Barry, With my pictures and camera, when I load them from the camera to my computer I usually crop them and size them to about 50% then click on the section at the very bottom of the posting area that says "click here to upload" A box will come up that says "browse" When you click on the browse it will open a section that shows your files. (pictures, my documents, etc.) You are then able to select the picture from there and click Ok and wait and it will upload it to the site and it will tell you when it's complete. If you have a dial up connection it may take a little bit to load. Then click OK at the bottom and your done. Then an angel will appear in the picture. Oh wait, that's my wife..........[8D]

Ok, a little lazy to look through 89000 posts, on the UCD w/ a Futaba 9C, how do you guys get the dual ailerons and elevator servos to work? Ive read the book and still cant get it right. I am using the 7 ch FM rx btw. What needs plugged in where and how do I mix it? I also would like to put "reflex" in for harriers and ele-flaperon for tight loops. Help please....... someone at another field programmed my Somthing Extra w/ these features and I cant copy it for this airplane......it's ready to go and the radio is holding me up......I know someone knows this... I wish you could "hot sync' w/ other people's tx....some day soon im sure.


The Mac

I just have an old cheapie camera which uses compactflash cards, so maybe
the new ones are different... But I just read it off the card or harddrive and
upload it here....

Hi All,

I flew several more flights today and I am really enjoying this plane. You guys are right - it makes me look a lot better than I really am

I'm trimming the model currently and I've actually found the lateral balance is fine. I need a little more right and down thrust though so i will be doing that and then flying some more in the next few days.

I'll keep you all posted,

Tony

BTW - the weather here in Oz (Adelaide) is quite nice at the moment - usually around 20 degrees C but a little breezy a lot of the time - the UCD handles the breeze fine though

Hey Tony... I was thinking I need more rt. thrust also, I'm not sure
if it was caused by my "Flat spin landing" and not getting it true when
repairing or just that I never noticed it before, but I'm seeing it now...
Anyway keep us posted as you said:-)
Pattern huh.... So the UCD does that OK??? I know it floats forever and
is a slow easy flyer, and it can make you look better than you may be:-)

Here is an issue I just had while replacing my 50 SX with a Saito 91:

The owners manual says to place the engine so that the black plate of the spinner is 5 inch (150 mm) from the firewall. 150 mm is just about 6 inch, not 5. When I mounted up the 50 SX originally, I didn't catch the typo in the book, and mounted the engine 5 inch out from the firewall. Everything seemed to mount great there, but the engine cowl was mounted about an inch too far back (the graphics didn't line up well). I think that the book meant 6 inch from firewall to spinner, but there is no way that the engine mount that came with plane is long enough to extend the 50 SX out to 6 inch. Has anyone seen this problem? Is there a way that stock engine mount can even get an engine out that far?

Thanks,
Rob

I can try to offer a little help - I have a 7C and I know many of the features are the same.

Both of the aileron servos and elevator servos need to be plugged directly into the rx (no y-harness on the ailerons) to use the features you're after. For the ailerons, plug the master servo into channel 1, and the slave into channel 6 (the choice of ch 6 is somewhat arbitrary since you can choose which channels the flaperons operate, but I think the default is 6). Then enable the flaperon mix in your mixes menu, and both of your ailerons should be working in unison, although you may have to reverse the individual servo directions to get them operating in the correct direction. For the elevator, there is a pre-progrmmed mix that links two elevator servos together. The master elevator servo needs to be in channel 2, and the slave ch. is your choice (not sure what the default is on the 9C). With these two mixes enabled, you can then enable "Ele-Ail" or "Spoilerons" for the harrier moves.

Good luck! Hope this gets you started.

Thanks Barry, but do you know if i can use my jr servos or not with that? i dont think so, im scratching as it is to get this, (the old lady) i mean the angel is starting to harp
and as far as the pics CeeGee has it right but you might also note that on a reg post the "click here to upload" is not at the bottom, you have to either click on reply or quote , it states this at the bottom of the reply page that i am typing on now, and when you click on it just click on browse next and it will bring up you prog , and pick where your pick are and double click on the pic you want and it will put it in the browse line, then click on ok, i think im confused now[&:], but if an old truck driver can figure it out so can you, i think .there i go again.

thirsty, i think you may be right about the right thrust, but mine seems to be minimal so i just use about 3 clicks right rudder to compensate, hovers pretty stable with that.and tracks straight too.good luck with the weather there, here its spring and all we get here in the western US is wind for about 3 days and a couple days are ok and then the wind is back, over and over till summer and then well be flying in the mornings, its so hot here in the desert,( me and raideron anyways)its hotter here where i live than it is in alice springs there[8D]cant remember where Adelaide is, is it in the desert there also?wow this sure is a lot of talking, i guess ill give someone else a chance,later

Gjeffers and Raideron,

When I installed the cowl the nose of the engine was just touching the left side of the cowl. I've now added a little right thrust and the engine is now more or less in the middle of the cowl.

I tried trimming it out with rudder but in pattern the plane has to fly true otherwise I have to compensate all the time and that just makes it harder. Hopefully I'll fly it in the next day or two and give you a report.

I chose this plane to practice my pattern with because it flies really well slowly - that gives me much more time to think about what I have to do. I'm going in my first competition this weekend hopefully with the UCD so we'll see how that goes. I am nervous though. The other reason for the UCD is so I can do some 3D stuff later on - it looks like a lot of fun and requires a fair bit of skill so I'd like to try at some stage.

Adelaide - it's where Australia hosted the F1 Grand Prix up until about 10 years ago - now it's in Melbourne. Adelaide is in South Australia - right at the bottom. They say South Australia is the dryest state on the dryest continent on earth. We get quite a long summer - it's hot usually from about November through to April or May and we often get long runs of 40+ degrees C. Winter it never gets below about 12 - 15 during the day so it's not a bad climate.

Regards

Tony

your weather and climate sounds about like here Tony, we hit 50 celcius sometimes but normal is around 45 in the summer, i am about 30 nautical miles from death valley where its about 10 deg hotter than where i am. anyways when it gets over a 100 we just say its hotgood luck with the competition, hope you do well[sm=thumbup.gif]

you can see my terrain behind the plane, pretty dry, but i love the solitude, im the only rc,er out here ,got the runway to myselfand yes that is a dry lake out ther with the worlds larges soda ash deposits in the world. a lot of borax also.[X(]

V-Twin, I have a 82 saito in mine and its mounted flush with motor mounts I noticed that the cowl doesnt line up and I wish it was a longer mount so I could have mounted the 82 out a bit more and not needed any weight on the nose to balance. Could try to locate a longer mount with the same bolt pattern or just put new blind nuts in ..
John

Gjeffers, I got my 9C super from Servo City and only bought the transmitter. (about $280.) They will mix and match so you can set up what ever you need............[8D] The area you fly in looks alot like where I launched high power rockets in Gerlach Nevada on a dry lake bed......... I think it is 40 miles long and 10 miles wide...[X(]


I have a plan. I'm thinking of taking my TT 46 motor off of my 4*40 and putting on my U. Stick and taking the OS 70 off my U. Stick and selling it to buy a Saito 100. That way I can use the U. Stick for a sort of trainer, especially on windier days, and sell the 4*. [8D]
Question is will the U Stick fly good enough with a TT 46? [:-]

Hey Gjeffers, SPUD here, Yeah thats the one the 9C is great and very easy to program. I got the synthesized one its great easy to to change to my other planes. Sorry I'm late adding my two cents I had reserves this weekend, and now I'm at work. I'm a fireman here in Miami, 24 hr. shifts. So it gives time to catch up on the thread. Go 9C you'll love it.


SPUDS out.........

hey CeeGee, i think someone around here launches missils(iChina lake NAWS)i see them sometimes.
and you didnt say what your gonna do with that saito 100??????????????????i could guess, but im not

Hey Spud, i sure like that 9c, but im torn because i have all jr servos and receivers so im also looking at the jr8103air pcm, im selling my telescope to get it so i have a few days to ponder.i sure like the 9c,do i need all new recievers and servos if i get it or will they work with jr stuff if same freq?

Hey Gjeffers, I didn't know you were a JR dude. Stay JR and go with the 9303. Thats a great radio, I almost went with it but I've had futaba my whole r/c carreer. If you went fut. you would have to change all your recv. & servos over.

SPUDS 2 cents out...........

Soooo...

I have been doing a little extra work (web programmer) and have been building up a little spending cash. After flying my U Can DO this weekend with my 46 AX, and seeing an Ultra Sport with an OS 70, i think i am going to spend some of that cash on a 4 stroke.

Its amazing how the trail leads you up and up and up in size and price. I started looking at the OS 70, then thought i would check the saito. Well since i am looking at the Saito 72, i might as well check out the Saito 82. But wait the 91, hey how about the 100. From $200 to $280 in 2 minutes flat.

The OS 70 seems to be too much of a weigth trade off for the power. The Saito 72 seems to be a better option at 4 ounces less. But for only $30 more i get the 82 at the same engine weight with an apparently heavy muffler. Oh its all so confusing.
