ORIGINAL: Jack211

I received my Can Do .46 yesterday--and it is the second worst put-together ARF I've ever had (Lanier's Dart takes first in that regard, pitiful): 1) I spent an hour trying to get all the wrinkles out of the UCD's monokote, no good, left those tell-tale, however narrow, wrinkles. Virtually every surface, especially the LE of the wing, cCAN'T be tightened, smoothed--and I know how to do that, built many a plane; 2) the two-bolt saddle, receiver, for the wing is OBVIOUSLY out of kilter with the fuse (that was a return-no return issue for me--if the wing was out of kilter, too. It wasn't!?); 3) the ribs for the top of the fuse do NOT fit into their three-sided holes on the former. There has to be 3/32" of space there, so the ribs are only contacted on two sides. Bummer; 4) the fuel tank wouldn't fit into the fuse until I took about 3/32nds off the upper cross support--which weakens the whole foreward end; 5) the forward pivot, dowel, for the wing wouldn't fit the fuse until I sanded the dowel down--quite a bit.

Did you guys find these production problems for the UCD .46? For $!50, that's a really poorly produced ARF. All my Hangar 9 Twists ($99), even Tower's Uproars ($89) have been near perfect. What gives with Great Planes?

I called Great Planes to complain. Naturally, they said they would replace the bird IF I returned it. I have to FLY it Saturday. And it will be a bird I shall not be proud of.

GP recommends 50 oz/in torque servos. Futaba S3004's are 44 oz/in. I'll use those, because I have them. Need I worry? They also recommend a servo reverser, expensive, for the elevator servos, but if you just turn one servo around, they work in the same direction. I did that with my UCD .60 and had no trouble. Is GP just trying to get our money, or is there very good reason for all the expensive hardware?

Very pissed,

Jack
Sorry to hear about the defects in your UCD.46. I would probably return it for exchange. Why is flying it on Saturday so important?

I have a fairly new UCD.46 and other than the below average Monokote job, it seems to be straight and well built. I also tried ironing out the wrinkles in the Monokote and had limited success.

As to your standard servos, I'm using the standard Airtronics 94102Z servos (50 oz/in torque) and they seem to work just fine. I imagine your 44 oz/in S3004's would be about the same. Not sure what you mean by "turning the servo around" to eliminate the servo reverser gadget, unless you mean installing the pushrod on the opposite control horn. I thought about doing that too, but that resulted in a less-than-ideal pushrod alignment. After looking at it, I went ahead and installed the servo reverser as recommended. I suppose moving the pushrod to the opposite horn would work, inspite of the misalignment, but my guess is that both elevators will not move exactly the same amount. This could possibly induce a little adverse roll with large elevator inputs. Just a guess, anyway.

Good luck!

Jack, I would return it if I were you. Otherwise you'll end up having to put up with it for a long time and not like it. [&o]

I also had a LOT of wrinkles in the monokote but after a while they all came out.
I used the servo reverser, got one at the hobby store for $10 and its a nice quality
item. My 7 CAP would have worked it out in programming but the trim would not
have worked.

Mine was a well put together model and is of very light construction. I am happy
with it even though only one flight before I discovered a hole in the fuel tank (my
fault).

Will be a fun airplane to fly with lots of potential.

yea, return it, i used a iron with a cover over it and with the right amount of heat the covering will shrink without wrinkles, mine did anyways, these things happen when they build them in the summer and ship them in the winter, it creates havic on the frames.but as far as the other problems i had none of those, my plane was great and i did use standard servos with good results.

id cut the hole patnjim, you can get the wrench in the front cooling hole to loosen the nut to remove the jam nut and i did mine lots of time without ill results with no locktite or any thread locker except on the end that goes in the muffler to reduce oil leaking and burning onto my pipe.

yes CEEGEE, the edge is great and you guys wont believe me but the edge does the inverted flat spinjust as fast and flat as the do (but wont rise) but it is beeeeutiful im really glad i got one and i love the speed also, my first fast plane[X(]

i also found a good use for those red ucd booties

sorry about those baddd pics cause i am way better looking than that

Nice plane.....! WoW! [X(] Who's that good looking guy holding your plane for the picture? [:-]

I'm getting a Funtana 40 this month and I'm assuming it will be somewhat faster that the UCD's..........

Hi all.... Well it "was" a Great morning until.. I even got some great inverted flat spins
and rising spins.... But as with anything, It must all come to an end :-(.... I was flying
inbetween training someone and on my last flight I was coming towards the runway to
pull into a low hover but just before getting to the runway the plane takes a nose dive
and no control, but about 3' I regained control, So I try to get in to land but control
was spotty then I lost control again for good:-(... The "Do" rolled over inverted and
did not stop until..... It's completely gone and on its way to the place in the sky....
It's hard to tell why I lost control... But I found one of the batterys lead at the battery
solder joint separated from the battery... Not sure if it came apart from the crash or..
But anyway it's history now......... It's a sad day... But it had some great history...

I've flown mine once and the CG was all the way back at 6in and it was fun.
The wind was gusty and I had to flght to land it, with the battery shifted forward
it ought to be better.

Too bad a new fuse kit and tail feather kit is almost as a whole new plane.
Gonna get another one??

you didnt waste a good inverted flatspin landing there did you Ron[X(]
im getting the same looks as you but come february (or maybe march) there will be a resuection in my hangar[X(]my new edge is a totally different fly but is grrrreeeaat in its own respect and i love it too(i like speed also)

thanks CEEGEE but that guys a lot better looking than me[:@] you will like the funtana i think as long as you realize that its a whole different plane (and get a high pitch prop) im ordering a x8 for mine

Hey Ron, Sorry for your loss. yikes! That looks demolished..........[X(] Pretty far gone.
Thanks for the info Gary. That's good to know and something to keep in mind.
I went flying today on my way home from work. It didn't work out good though. It got cold waaaaayyyyy too fast and I wasn't prepared enough for it. I hate this time of year. [&o]

Raideron, sorry to see you lose your UCD it looks to be in real bad shape. I hope your SAITO engine and servos survived the crash. Get another UCD and continue to post more messages and pictures as I enjoy reading this forum as I'm sure others do too. I'm a fair weather flier and it has been in the 20's here in Tennessee so looking for a kit to build this winter. Good luck

Gary...Rob...They say do it well if your going to do it at all
The "Boss" is now saying, the only thing I want for xmas is another plane like that???
Is this a trick??? The ground feels real soft to me..... Dad would say tread lightly my son..

KO4Z... Thanks.... Not sure on the Saito, it looked OK except for a dent in the intake
pipe... throttle servo had a broken tab.... Hey My landing gear block hung in there
I need to check all when I get back home... Could not do it at the field except put it
in the car, as I was training a new member, and we left for Vegas as soon as I
got home..... The reciever will be sent in for a check up.... It was my new rec. for the
S.T. which I used in the "Do" while sending the "Do's" in for a check up....
20degs..... WoW..... My hands/fingers the last few time at the field felt like it was about
to fall off at 40+ degs here in AZ.... Had to stand by the fire pit to warm them up...

Despite the production problems with my Can Do .46, I maidened her successfully today, off a snowy road, winds gusting to 20 mph, 90 degree cross-wind to the road. Two left clicks on the ailerons and she was trimmed, so I must've done something right in building her. The O.S. 61 was hard to start (15 degree weather) and flamed out at 6 minutes the first flight. The Can Do floats marvelously, I discovered, and plopped down in deep, soft snow. The pressure line had a break at the Pitts muffler, which has a very sharp brass nipple. I may have been rough on it with gloved hands.

I put in an O.S. A3 (hot plug) in the .61 and had an excellent second flight, 12 minutes, making the Can Do KEs, hovers, and inverted spins, EASY! You guys were right. This plane is fun! Easy to fly. I harriered the last landing and put her down in 10 inches of soft snow, tail first, just for fun.

I love the rudder and elevator command. I used full rates starting the second flight, but remember I'm used to the Twist, equally acrobatic and quicker.

I'm sure this bird will teach me a few things about what she can do, but I'm anxious to teach HER what she can do.

Thanks, all, for your help and encouragement. She may be uglier that she needs to be, but she flies marvelously. I guess I can burn the boxes she came in now, huh?

Hey Jack211... The "Do" with the foward canopy and long tail... Looks a bit different,
But as a fun fly and a floater/ lander.... She will teach you a few things... There is
somethings she may not do well, but all that she does, she does well and the best
part... She's Great at what she does and a whole lot fun while doing them:-)

Default RE: U-Can-Do 3d 46?

Thanks, Raideron, I'm always looking for a bird that will teach me something.

See pix of the Can Do. I decided to wait until I liked the bird before I inverted the engine and put on the cowling. I detest the long name, though, and when the decals go on, I'll edit the U-CAN-DO 3D .46 to Can Do--besides, I enjoy the imperative.

For those still thinking about buying a .46, see the way the pushrod is bent, two 90 degree turns for the right elevator. The OTHER side is as the book recommends. Yes, there may be more give in the right side because of those bends, but I haven't seen any degrading. I tried several "Walls" to test it. Bird went straight up. If the right elevator had bent, you'd get a screwing vertical, hm? I took a 24" extension, plugged it into one servo, then, having put the other servo wire through the fuse, I soldered it onto the extension.

Doing things that way saves you a servo reverser AND buying a "Y-connector." But that's me, cheap. The servos are Futaba S3004's, all of them, another saving. But I put Du-Bro arms on them, except for the throttle servo, a Tower TS-53, with a common arm. I WILL watch the servos' responses and operation because they are, SLIGHTLY, overloaded. The RECOMMENDED servos are 50 oz/inch. The S3004 are 44 oz/inch. I called a GP technician on the subject, by the way, and he said they OUGHT to work okay. So you CAN save the money and still have the Can Do 46 work fine.

This morning I burned the boxes. So my Can Do is my hangar to stay. It's the first bird I'll fly today--if the winds come down from 30 mph gusts.

Raid, do you like that yellow canopy?

The snow in the pix will give you an idea of what we're flying in. We have 37 inches of snow this month and 73 inches since Nov 16, when it started falling.

Skiis work! Fly well.

Jack

Judging from the way that long arm looks in your photo you could just as well have used a straight push rod and put the control horn on the bottom.

I use S3004's in all my U-Can-Do's (see photo of my fleet below). That's 18 S3004's holding up through everything I've put them through including blenders, walls, snaps and knife edge loops.

Hey Jack211.... It looks COLD... But it has to be a big rush flying in that white
stuff.... Guess you dress well for it... My hands feel like there about to fall off
here in the AZ "Cold" of about 40degs.. Bet it's a blast flying off of snow...

I must say the pushrod looks a bit different.... But hey... If it works... But watch
for flutter, That tail end may not take a lot of it.... I use HS 425's and a HS 645
on the rudder... The 425's has held up well.... Well that's when my "Do" was
flyable..... Love your canopy....

I'm working on a deal for another "Do" If I do get it I'm just going to blacken my
canopy out.... I did not like the smile my pilot had on his face after my crash.....
I have to go and clean out and check the S-100 in hopes it came out OK.... I'm
also boxing and sending the rec. and servo for a check up....
Now I just have to figure out what to say when that Brown truck comes twice...
Once for the OMP 46 V2... And maybe the new "Do".... I guess I could say it's
just parts to finish putting together the Showtime.....

Gees, Raid, I'm anxious to hear about the Showtime, looks like another hot plane--but not cheap. I'm really anxious to find a bird like the Twist, only twice the size. I run a Saito 82a in one of my Twists. I want a Twist I can put a Saito 1.2 or the new 1.25 into. How are you going to power the Showtime? The Saito 100, did you say?

About that effing, smiling pilot of yours: take a torch to his face--at least, THEN, it'll look as if he's paid his dues. You obviously have, Ace.

After many planes with and without pilots or decals for instruments, I've decided to paint ALL my canopies. I have a black one on the Uproar, a red one on the Can Do .60, a black, a green, and an orange for three different Twists, yellow for the Magic, Can Do, and Extra.

I flew the Extra, only, today. Best plane for the wind, which were gusting to 30, and I didn't want to put up the Can Do. I came close. I put her on the road away from the blowing wind while I checked conditions aloft with the Extra, and the "Can Do" decal on the bird kept laughing at me. SHE was willing, but I wasn't. Had the wind not been crossways to the road, I would have put her up. The snow's yet too fluffy to support the skiis.

Yes, 'twas cold, 22, +7 wind chill. But those birds against those clouds....

Hey Jack.... The Showtime will be powered with the YS 110 with slimline pitts
If I get another "Do" the S-100 and the OMP V2 with a YS 63... They all should
be fun...

Yeah my pilot is history... I like the blacken canopy's...

Well don't lose sight of your planes after seeing all that white:-)... If I do get
another "Do" I'm thinking of having a float setup for it also... That would be
almost the same as skis, but a bit warmer:-).... And it would be awesome with
the tail in the water.... Well as long as it pulled back out:-)

Rock, I thought so, too, but THEN the elevator works OPPOSITE the other side. Try it. On the Can Do .60 there's enough room to put one elevator servo arm UP and the other one DOWN while keeping the horns on the SAME side. The .46 doesn't have that room. I played with that bird for more than an hour reversing the servos end for end, putting the arms up then down.... What you see is what worked, the ONLY way it would work without a reverser.

I am SOOOOO happy to hear that your S3004s are doing the job. I had NO idea what the .06 oz/inch difference would make in the long run. You give me hope. I do NOT want to crash that bird because of a servo failure.

Thanks, Rock.
