LL, The only thing that I anticipate with the tank on the CG is that now my battery may be slightly forward of the other models with the stock location. But still I will target the CG that I am used to. As far as drape cords on the rudder, the Ministry has a patent pending on that application and you may need to apply for a special use permit. Joe

YO Yo Yo, Got my "Cline" fuel regulator today. Oh yeahhhhh !!! Now if only Quantum Models will ship my "Earnst" thrust plates, I could finish up on this. Looks like 3" to 7" snow for tomorrow. This is like Alaska. Later, Joe

[]U-CAN-DO 60 WARNING!!!!!! Be sure to frequently check the bolt in the front fuel tank cap!!!! This threads into a metal backplate and vibration can cause it to loosen and fill your fuse with fuel(nasty-nasty-nasty). I've always had plastic backplates and they stay tight. Yesterday was my fuel in the fuse day and I hovered a few times so I had a real mess...... MAINTENANCE .....Yes I know and I do but I never thought about that bolt loosening up...Check Yours..
To all the dry fuse's,
Eddie

thanks for the heads up, will watch for that

so the ys 120ac i traded for will make a good engine for the ucd 60?

i guess i might as well make a list of the thing to do...

fix lanfing gear area
glass the firewall and maybe even put in "pins"
find some kind of metal motor mount?


i still have pieces of my first ucd..it had os91fsII and was a pig...i am about 20 times better than i was when i had that plane...and i am hoping to have a freakin' 3D bad ass whith the ys120 on the nose..

wonder if there is ground clearance for a 17X6..?

what do you guys think...enough power or just stupid..? i do not have another engine to put on it...

If you have pieces left of the firewall you will notice that there is not a whole lot you can pin to. My thoughts were to install some kind of rods, wether aluminum threaded or thin dowels and go from the firewall to the next former in line. I think a YS 120 will at least taxie it. Good luck, Joe

Kevin,...Hi..!
As you probabally have seen from this thread i'm in the process of putting my first UCD together i was going to use the .91 O.S.FSII in it...a couple of guys have said how well this combo is starting to work out, what where you not happy with..? regards Dave.

lord vulcan...it is in retrospect that i say i did not like the os91 combo on my ucd...it did tricks ok...pulled out of a hover(what hovering i could do back then) somewhat...and to be honest, i could not really do anything more than very short knife edge's (coupled all to be damned) snaps, harriers, and very shoprt hovering...

but now that i have become a LOT more 3D oriented, du eto foamy electrics with 3:1 brushless set-ups, i can say that for me, the ys will be a lot better...i know that i will be trying stoopid things like tail touches, rolling circles a few feet off the deck, crazy snaps and violent manuvers and things like this, and as best i can do them, you have to have an overabundance of "ooommph" to do them easily...if i can get 2:1 or even 2.5:1 with the ys 120 and 30% heli, then i will be happy...the plane may not survive even as long as my first one did, but at least i will have enough horse-pressure...

try an apc 15x4w on 30% and you will do ok...i am very close to sea level and that combo worked really well...i also liked a zinger 14x6 but it exploded due to an attempted harrier landing that kind of ripped the landing gear out....

good luck..

if i were you, i would try to get a bigger motor..a saito 100 is also a viable motor..from what i have seen, they have a good deal more power than the os91 and weigh a little less...but find you a 120 or a 1.10fz if you can..i think you will be happier with it in the long run..!

here i am with my ucd..."look..i am hovering..!"

then.. "oopss....is that supposed to happen..?"

a few repairs from repeated attempts at tail touching and other failed 3D manuvers

the fatal last day of my UCD...

i was really doing well..i actually made a knife edge pass all the way down the runway...

that got me all excited so i decided i would harrier around down low and hover close to my head...

well..the pics are self explanatory...

RIP UCD3D...

and yes...i am a fatbody...so no need to comment on incredibly fine backside!!

Hi Kevin ..
Hey..! ..you've managed a lot more than i have with your UCD....not got mine built yet ,let alone in the air...
I've got a YS lined up for the UCD...but i was going to put the OS.91FSIIP in first .... a sort of " walk before running.." excersise...i'll still probabally make a mess of it though....keep the pictures coming ...were getting quite a UCD " gallery " going....
Maybee father Joe from the "ministry of aviation" could offer a few words of comfort on the passing of your UCD MK I...!.. cheers, Dave

Kevin, welcome to the community. I don't see any thing with your plane that a little duct tape and drape cord couldn't fix. Get used to that sight if you continue to put these planes through their paces. They fly so great you just can't help trying things that you wouldn't even attempt with other models. What is the weight difference between the YS110 and the 120 and relevent BHP of both. Just curious. Good luck with the next one and forget about landing gear, that 120 should hover right out of your hand. Joe

Great pictures, Kevin. Sorry to hear about your loss. Been there many times myself. Guys, are we talking about the same engine? I think Kevin was using a 91FX. LL you are using a four stroke 91FS. Just wanted to keep this straight.

The CG discussion became a bit complicated. I was merely asking about how mounting the tank over the CG would impact flight characteristics as the fuel drained. Joe provided a good explanation. LL I like the idea of mounting the tank a little forward of the CG until you feel comfortable with how it handles. This is what I would do if it were me, though as Joe stated, this plane will make you look good. I just wouldn't want to take any chances on a plane that has never been flown. No two airplanes are exactly alike from my past experience.

Roger, I totally agree with starting out at the recommended CG of 4 7/8" which is nose heavy. As far as the tank goes as a form of ballast it is not reliable due to change as fuel draws. Let me specify that the variations are more noticible in advanced stages with a more aft CG. My feelings on a remote tank placement make the planes characteristics more consistant. With the tank on the CG the battery can now go forward to obtain 4 7/8" After becoming prolific with the model and a desire for more aerobatic performance comes into play the battery can now start to move aft to a more tail heavy attitude. With this set up, full or empty, the tank does not effect the CG. Joe

Roger...i was using a surpass II .91...it was ok...but i can't wait to try the YS..!


i have never seen one of the 110fz motors, but i am sure that my 120A/C is probably several ounces heavier just from what i have read...

but i can always just mount my pull-pull closer to the tail to compensate...as i am sure i will be way nose heavy...maybe i can ask mr. shadel about the weights...

i have never seen any BHP figures for any of the YS motors...like it is a closely guarded secret or something...but i have to say that from firsthand experience with my little ys63..i would bet money that it pulls harder than my 91 surpass ever did...if i can afford to, i will never have any other glow motor but a YS from now on...

there is a local TOC guy here that has an old trashed ys 120a/c like mine on the huge aerowoks profile...and it hovers that 13 or 14 pound monstrosity with ease! and it has an estimated 50 gallons of 20% thru it...yes..i typed 50 gallons! without rebuild..but it is about to need a new front bearing...it is the most impressive glow motor i have ever seen...

i will try to get my u can do in the next week or so and then get some action photos and video...i got a cool new video card from the in-laws that allows video capture...so i got to learn how to do it..but maybe i can get some vid and sound for youguys....

Kevin, if you get to post videos please see if you have the option to post it in an alternative formatt as well as WMV which most guys use. I'm on a Mac and miss all the good stuff. Thanks in advance, Joe

Hi Kevin again ...

THOUGHT i spotted a pull /pull set up in one of your pics, i still fancy somthing along these lines..... sort of 'servo out of the breeze' set up...if the tanks on the Cof G....then..?....with that weight not there anymore... and the relatively light O.S at the pointy end.No..No..no..no..no..Joe wont let me, he said I've got" Drape feever " or something..!

Dave..

yep..the pull-pull was kind of just hanging out..but it worked really well..that was a 200oz/in servo on there! hahahah way overkill, but it was a little heavy, and i needed it...it worked great...even though the unintentional tailtouches usually resulted in ugly harrier landings! that was one tough servo! it has since found a home in a friends savage .25 monster truck as asteering servo!


i plan on using hitec 5245's on surfaces this time with a hitec 5945 on the pull-pull....try to keep it as light as i can with that hog of a YS on the nose! hahaha


i will try to learn how to export videos in more than one format...i suppose you need avi..?

i am sure i can figure it out...

the video probably will not be worth watching anyways...i am so used to these little electric foamies that i may forget myself and piledrive the UCD..!

you will love the Ys 110fz.....With a 16x6 APC prop.....JW

Well guys, the drape monster finally made it across the ocean and bit me in the ars today. My wife had me hanging cornice boards with my father-in-law, and while doing this domesticated deed I couldn't help but think about how LL had somehow passed this dreadful curse abroad.

Tears of laughter, misery loves company.!.. remember, this is just a place you are passing through... we will pray you are there but a short time ..next cometh the bedding plants ...slugs ...snails and things that go munch in the night... they are mearly distractions to keep you from your true mission... look towards the light....past the drapes..! Chant ...UCD!....UCD!...UCD!....!

Yo, ordered my servo arms and thrust plates on the 12th from Quantum Models. Today is the freakn' 19th and have yet to cross my threshold. Now I know that they are not going to show up on the weekend, which would have been nice. All I get on the web site is that they shipped, no dates. That means they could have just shipped today, so there is another week shot. I wasn't going to fly with the 8" of new snow but I could have worked on it so I would be ready when it melts. What the flyin firetruck takes so long to pull stock and ship it out? Joe
