thanks Rob, i may just go with that one:D

gjeffers

sorry about your loss

at less your 60 will get some runtime:D

RE: U-Can-Do 3d 46?
 

yea 38, got her going today and got in 5 flights and she still flys like a dream, will get a new baby do soon also!! so nobody feel bad for me cause im still havin funnnnnn:D:D

RE: U-Can-Do 3d 46?
 

Gary 300 flights. Thats more than I have on 4 planes combined. Glad your up and flying already. Is the 60 similar to 46 in how it flies? Exactly how high is 2 mistakes high.


Rob Katana 40 or 70 size? I have a 70 that I got off Ebay. Not started yet. Sure love UCD so far. Where did you get the Tetherite gear?

Doug:)

RE: U-Can-Do 3d 46?
 

Dougwill, I have the Katana 40 size and have to say that yesterday was my day of flying. Man I had fun!! What a kick!:D
Oh, I got the tetherite LG set from Ohio Model Planes. Here's the link - [link]http://ohiomodelplanes.com/tetherite/[/link]
I flew the Katana once and then got out the UCD but the Do really didn't seem to fly the same as it usually does. It just seemed to be acting funny and not as easy to control as usuall so I set it aside and flew the Katana most of the day. Later I was talking to a more experienced guy about the Do and how it was acting and he said that the Futaba 3004 servos that I have been using for the elevators had probably stripped a gear or tooth or something. That sounds pretty likely. Yikes! [X(] I might have lost my plane if I had kept flying it..... [:-]
But that Katana profile.......[X(] Boy is that ever fun to fly. I can do lots of stuff with it. I set it down on the grass after one of the flights and next thing I know I had about 5 guys standing over it looking at it and asking questions. Very fun... not as fun as the Do of course, but very fun.

RE: U-Can-Do 3d 46?
 

I have already bought this plane but I am not sure which engine should I buy. Since my flying field is about 7500 feet above sea level I am thinking about a Saito 100. If I install this engine, should I consider any modifications positioning the engine mount? How about a YS 63 or a OS .91 Surpass with pump? I am planning on using a Perry oscillating pump with the Saito 100 so I wont have to worry about the fuel tank position. Any ideas or experiences?
Thanks

RE: U-Can-Do 3d 46?
 

cafusin, you really dont need to move the tank, and if you go to page 75 i have some info on mounting the 100. i havent time now but ill dig up more info later and get back to ya;) just keep the questions comming and youll get more answers from everyone here!!

ps. the mount in the pic on page 75 is a ucd60 size mount (great planes 60-120 size)you really dont want to mount it on the stock(small)mount.

SCTCRASH
My UCD 46 has the same problem with needing 10 clicks up for level flight. which requires down stick on inverted flight. There was a post somewhere back there about trimming plane out to neutral flight upright & inverted. Not sure where. Mine balances at 5 1/2" also. She flies great even with up adjustment. Up thrust should work I would think. Plane is so forgiving on low rates. You gotta love this plane.

RE: U-Can-Do 3d 46?
 

Hey Gary... Just an update on the Skysharkrc.... I never could get in contact
with the guy at eagle, just his help that is running his hobby shop, he said he
heard about them but nothing more... But a few at the field said that S.S. has
been in Havasu for a while, selling their planes, but no real hobby shop for
parts etc...But that could have changed?.. But no reports on their planes and or
service... They did say a club member won a drawing of one of their planes at
a fun fly(not the 540) which looked good.... But he has never put it together....

Great 5hrs. this morning at the field... No UCD, But the 4*/Saito ran great...
Now using the 16X4W.... Guess I'll need bigger wheels... I only had about 1/4"
ground clearence with the tail in the up level position... Made a bunch of T.A.G.'s
and landings... And the prop is as it started:D... I was going to uninstall the
saito... But I readjusted the valves and had the new prop... So I had to try it..
Gary.. were you using this prop??? And the Profile is flying like it's old self?????
It was taking a bit more to hold it in a invert flat.... But the last two times out...
It pretty much went into it anytime I wanted it to... The last two mornings where
AZ. cool :-).... So I guess it was just the thin air??.....

cafusin....7500= Saito 100.... IMO.... I would go with the bigger mount also....
I think the stock tk position will work... Or just trim the F.W. hole and tank saddle
a bit... You can lower the tank 1/4 or a bit more before needed to trim the motor
mount, I used the stock marks for the engine mounts... That's what I did to mine..
If you do go with the Saito 100... At least make sure you have the 10oz tank...
which will fit in the location.. Seems like a few had the 8oz tks. and the later
models came with the 10oz???... My used UCD had the 8... and now a 10oz is in
there.... The saito will run a few seconds longer:D

On a little sad note... Members at the field were talking about how our "free" flying
site maybe close to being over in the unknown future and/or runway shorter....
Talks about shops and homes are getting louder[:@]..... You know what that means:(

gjeffers
new ucd?:D
anyway looks good

RE: U-Can-Do 3d 46?
 

oh no Ronl, not the cancer of society moving in on you[:o]

been checking around about skyshark and have had a little luck with good word about them and just saw a post about them in the giant scale thread and Q'd the guy just now and he lives in Vegas so im just waiting
for his thoughts.
yes i have run the 16x4w on my papa Do way back and really didnt like it, just to slow and had to push the engine all the time seemed like and slow spool up also, i just like apc 15x6 on my 100;)

has been really nice here too:D 65 this morning, got rained out for work so i guess ill have to fly the 60 size all day tomorrow (did today too):D

well we got a new contract signed and seems we will be hauling salt to las vegas every day starting in dec so ill have access to real hobby shops now,(will have to drop my trailer to go shopping) but just in fuel ill save a bundle.(just ordered 6 new model 79 petes with all the chrome)[8D]

RE: U-Can-Do 3d 46?
 

thanks 38 but not yet, im flying my 60 size for now, but will replace it soon:)
i pulled it off the wall and it flys again(and tomorrow too!!!)

RE: U-Can-Do 3d 46?
 

I too was not sure of the spool up with the 16X4W... But man it throws alot
of air... which I did notice on hovers of the 4*... Tho, the spool up was slower
the added air made up for it so I'm still checking it out, I also picked up a
15X6, but did not try it yet....

Yeah.. They are sure building a lot here... We thought with all this heat.....
It may still be a while... They can only play with dirt now..., piping work is
1-2+yrs away.... But with the playing of dirt... It may shorten the runway by
40'........ Maybe that's why I got the 100... The 4* can get up in a few feet,
with the 100 on the UCD I could problely hand launch it:D And you could
always do an "upright" flat spin landing:eek:

RE: U-Can-Do 3d 46?
 

look at the ouch thread Ron, i think some of the people there think im nuts[&:]
and i have actually thought of a hand launch too!!!!:D (but wont)[X(]

RE: U-Can-Do 3d 46?
 

Hey guys, I got to fly a 60 today..... [8D] [X(] One of the guys at the field has a UCD 60 (and about 20 other planes). He brought his 60 along today and really doesn't like to fly it so he had me fly it. He said "if you crash it, don't worry about it, we'll just go out and pick up the pieces." So I took it up to fly around some.......... Nice flying but it only has an OS 91 so it seemed really under powered compared to the 82 in my 46. Fun to fly the bigger model though. [8D]

RE: U-Can-Do 3d 46?
 

yea, i have my 100 in my 60 size now Rob and it just isnt the same[:o]
but is is a peach to fly:D

RE: U-Can-Do 3d 46?
 

Yeah, the one I flew with the 91 seemed kind of underpowered especially trying to do a hover. Beautiful plane though. Man! That is a daisy.......[X(]:D[8D] Would like to buy it from him but I'm still out of work. (on strike)

Hey Ron, Sorry to hear about the developing going on...... [>:] There's some neighborhood somewhere around here that is complaining about a gun range that was there long before the neighborhood. [>:]

RE: U-Can-Do 3d 46?
 

:)gjeffers...I read that "ouch" thread. They were making fun of you. They just don't know you. Starting a plane in the back of your truck...I don't see anything wrong with that.
With the 60 you've gone from Super Power to power. The 100 is just barely enough in the 60, at least at my elevation. Use 30%, it helps a lot. But I flew mine like that for a long time, but the 110 is more fun.

CeeGee...About that gun range...just point it at the neighbors. Should solve the problem.

Radieron...Upright flat spin landing...Sounds fun!!!! Sounds like you need bigger wheels or taller landing gear. I use Dubro 3" Super Lite tires. The only weigh about 1 1/2 ozs for both and it gets the engine a little higher. Also, I think gjeffers is using UCD60 landing gear on the 46. It's about an inch taller also. I think with the 100 on the 46, it won't matter how long your runway is.

gjeffers....It looks like you have a lot of room in your flying area...Wouldn't it be a riot for several of us to meet at your field and give you some flying buddies!!! Maybe this winter. You know...when it's not several hundred degrees out. That would be cool. I could bring 3 or 4 UCDs...maybe that would be enough for an afternoon or two.

thanks
Barry

RE: U-Can-Do 3d 46?
 

Try to pull full back on the elevators right when your leaving the ground, as soon as it lifts off hold it in the full up elevator position, then shut your eyes and listen for a wonderful sound.:D

RE: U-Can-Do 3d 46?
 

Life is a Death Spin

RE: U-Can-Do 3d 46?
 

Hey guys,

Would the U can do 3d .46 be a good second plane? I am looking for something unique for my next plane. My first was the Hangar 9 Alpha, but know I get bored with it since it only does mild areobatics. It seems like everyone and there ucle gets a Sig 4* or tiger for there second plane.

RE: U-Can-Do 3d 46?
 

Hey Savage, Welcome to an awesome thread where you can find out everything you want to know about the UCD's and some things you don't. Depending on your skill I would say the UCD's make great second planes but I think that with a 46 it will do only mild aerobatics and you may get bored with it quickly. While an 82 Saito or 91 isn't required to fly it it will sure make it tons more fun to fly and aerobisize it, much more than a 46. In the long run you'll probably be happier with at least an 82 4 stroke. [8D]

RE: U-Can-Do 3d 46?
 

Barry, That's a good idea. (about the gun range) I didn't think of that...........[:-]

RE: U-Can-Do 3d 46?
 

S-a-v-a-g-e... Only you will know.... But I feel the UCD "can" be a good second
plane depending on that persons skill level.. With low rates it does fly real easy...
Floats and lands great... Better than a trainer IMO.. Turn on the hi rates and let
loose.. Those big control surfaces will throw the plane around... But it will "not"
take the abuse the "normal second" plane would take... "excessive "Big" stick
movements or continued hard landings"( even after strenghtened the L.G. block..)
Now the UCD will handle 3D moves... And IMO is one of the eaisest planes to fly
But if you add to it.. a lot of over correcting, Hi speeds etc. that normally goes with
a second plane... Something may come apart IMO.. Just my thoughts....
She will make you look better than you think you are:-) But.. get to brash to soon
and she will slap you back down one way or the other.. But you have to love the "Do's"

RE: U-Can-Do 3d 46?
 

Ok, I have heard that the landing is most vulnerable part this plane. Does anyone make some stronger ones? I was thinking carbon fiber? Or is there a known converstion were I take the landing gear of a different plane and bolt 'em up?

RE: U-Can-Do 3d 46?
 

that would be great Barry, all you guys would be welcome to come down(and up for Ron) but yea there is plenty of room for us all and no rules[X(]we do have great weather comming:D

RE: U-Can-Do 3d 46?
 

Savage, welcome, thats exactly what i did, i had a alpha and went to a ucd 60 then a 46, but i think the 46 would be a great 2nd plane, my son did it that way;)do it!!!!!

RE: U-Can-Do 3d 46?
 

S-a-v-a-g-e.... It's not the L.G. it's self.... But the area the L.G. is connected too..
As with most 3D type planes... Their build "light"... Though strong enough for....
say a thrid.. fourth plane... It "may" not be strong enough for a second plane..
taking the above description.... She does fly, land easy..... But abuse is not one
of her virtues.....

RE: U-Can-Do 3d 46?
 

Savage, Yeah, what Ron has said is exactly right. They're made light for 3D type performance and also don't want to be flown fast. And yes they are easy to fly.......[8D]

Hey Ron, Where's the picture of your profile??? [:-]

RE: U-Can-Do 3d 46?
 

I'm new to this thread, but I just built a UCD 60 powered by a Saito 1.0--definitely NOT overpowered. I have about 70 minutes on it. I don't fly it "fast," not the purpose for this bird, but I WAS hoping it would be as acrobatic as my Twists (one with a .45 Super Tigre; one with a Saito 82a, love them both). The UCD is NOT that acrobatic, my opinion, but I'm still learning from the new bird. Admittedly, there's a different grace to it. And I'm learning to overcome my prejudices for the Twists. I flew all three of them tonight.

My question is how do you QUIET the damned thing? The resonance off the UCD's monokote wing sounds like someone beating it with a cat o' nine tails. All of my birds have unique sounds in the air: the Dart whistles, the Uproar and Big Stik whisper, and the Twists sometimes reverberate almost as badly as the UCD 60, but NONE of them is as noisy as the UCD. [I've put heat on the wing to tighten the monokote, no help. And it is NOT a problem of vibrating control surfaces--it happens on the table, where I can see it. The space between the ailerons and the wing is the thickness of one sheet of paper.]

The prop (14 x 6) and spinner are well balanced, and checked again. Any ideas? I CAN learn to live with the sound, but I'd rather not. It gets between me and the beautiful sound of that Saito.

Question #2: anyone have over-heating problems with a Saito and the UCD's cowling? This Saito 1.0 was previously on a Hangar 9 P-51D. In the 5th flight the Saito, with cowling, quit as I was about to turn upwind on approach. The lost power did me in: no speed, and not enough altitude to recover. That was the FIRST time that Saito quit in the air. My only reasoning was it overheated. I have YET to put the cowling on the UCD because of worries re: overheating--and when I change to a 15 x 8 prop, probably tomorrow, I STILL won't have that cowling on--and when I DO put the cowling on, I'll richen the mixture--to probably 9300 rpm. It's now at 9500-9600. Any comments?

About the UCD landing gear: I can see how they might come off if you landed badly--and it would mean rebuilding the whole front fuse if you did. So... what's so bad about learning to land with grace and aplomb? The UCD lands (and floats) like a dream. I flew tonight in 23 mph gusts--no problem. AND I had one flame out--when I got so excited flying I forgot about looking at my flight clock. Ran out of fuel! 'Twas the best landing of the evening. If you can't land the UCD without taking the wheels off, you've done something very wrong with the CG--or you are beyond your skills. Someone else said it: if you have a problem, look in the mirror. And there's your teacher, too. In the mirror. The teacher MUST be honest. As for me? I try not to use the wheels at all. Flying is not about "rolling," hm?

But we make mistakes, I know. So, if we can't learn from our mistakes, why make them?

Jack

RE: U-Can-Do 3d 46?
 

Hi Jack, Mine sounds like a snare drum too. I think it is because the the ribs in the wing are spaced so far apart that there is a lot of surface area to vibrate. Short of adding more ribs to take up some space, I don't know if anything can be done to fix it.

RE: U-Can-Do 3d 46?
 

:)Jack211...With that Saito 100 you need a lot of room for the air to get out of the cowl. I basically cut the entire bottom out of the cowl and a great big hole up in the front to get the air in and out. Open that cowl wayyyyyy up. If you get enough airflow you won't overheat.
Also, you need a different prop. I used a 16x4W, some would rather use a 15x6 either is an excellent choice but not a 14" and not an 8 pitch. That will help with the aerobatics. You'll find the UCD will hover easier than the Twist and KE better and when you get used to it I think you find it's more fun to fly. 30% nitro will really liven the Saito up too.
Welcome to the thread and have a great time here...and of course, at the field.
THanks
Barry

RE: U-Can-Do 3d 46?
 

Barry
You were dead on concerning weak set-up on tail-wheel. Bumped it and knocked rudder loose. Will put the
tail-wheel bracket on fuselage instead of supported on rudder. Flew 2 flights yesterday in 10+ mph winds.
Sweeeeeeet! Definately flies slow enough on low rates to be a good trainer, if you have a little help with landings. So far Saito 80 is plenty of engine for me. Watched what happens when you fly a UCD low with a strong tail wind. Flipped it over and right into the ground. Busted fuselage in half. so stay high.

Doug

RE: U-Can-Do 3d 46?
 

CeeGee.... Heck I lost it:-).... Here another of the Kangle SU-31...(red is where
I broke the fuse in half after running out of fuel and not making it back to field)
Oh and the S-100 on the 4*:-)

dougwill.. I too hate the tail wheel on the rudder... It's best on the fuse:)
But have been lucky so far on my "Do" It's still on the stock setup with no
problems..
On taxing with a tail wind... sometimes it takes down elv. with little throttle to
help keep the tail down... But in those times.... float her in right next to you
and grab it:D

RE: U-Can-Do 3d 46?
 

Barry, CeeGee, thanks for the input. Tonight I put the 15 x 6 prop on the UCD 60. Took off in five feet--10mph wind at one meter, gusting to 20 at 10 meters, so I had a hard time figuring out just how well the new prop was working. When I removed the 14 x 8 prop, I found it slightly out of balance--maybe some reason for the increased noise previously. The noise is still there but not as bad, and I was able to hover across the sky in the wind. The real challenge is keeping verticality in the torque rolls and the BOTTOM of the bird is towards you, rudder reversed. More to learn, joy, joy.

I flew three different birds tonight--for pictures. Tomorrow it'll be all UCD 60 and I'll learn her well. I got my remote glow plug igniter tonight--from a friend--and will put the cowl on--with big holes exiting. That ramped groove aft of the firewall bottom is there for that reason, lots of air outlet, hm?

Thanks again.

Jack

RE: U-Can-Do 3d 46?
 

Jack, Sounds like you had fun...... [X(] Glad to hear the noise has calmed down some. The guys at the field used to comment about mine all the time. I don't know if it's changed or I have gotten more used to it.

Ron, Cool looking profile......[8D] I'm having a ball with mine. I ordered 2 more.......;)

RE: U-Can-Do 3d 46?
 

Hello all:D
Raining here in Ohio today:(. Yesterday we had a picnic, fun fly at the field. Great turn out.(pics to follow) Too windy for me early on. 10 to 15 mph. Too many people watching also. 3 46 UCDs flying. gjeffers you would have loved the low inverted passes in windy conditions. (2 -3 ft.) These planes are amazing. The comments about how extreme to how trainer-like these planes can fly. Starting to get used to this plane. Will fly a couple more tanks on low rates and then kick her up a little. Where do you start as to acrobatics?

Doug:)

RE: U-Can-Do 3d 46?
 

Hi,
I am new to the hobby and this post. Just got my 46 ucd together and few her yesterday.. ucd is my second plane. My first was the nexstar. Just want to thank all of you 4 the great info you post. built my ucd with all the upgrades i found on the thread. My question at the time is where to buy a cline regulator? I have the classic fuel ploblems with my Saito 82 on the ucd. Thanks agin to all for the help with buildin the ucd with info from the thread!!

RE: U-Can-Do 3d 46?
 

:)gone2theriver...Congratulations on your maiden flight. Welcome to the thread. I hope your stay is enjoyable.
Thanks
Barry

dougwill...A good place to start your aerobatic adventure is with figure 8 and cuben figure 8 and inverted flying. And of course start practicing your hovers, they take a long time to learn. The inverted flat spin is easy with the UCD so that's another one but save if for later. And of course my favorite...the inverted flat spin landing.
