RE: U Can Do 3D
 

:)rclement...You'll love the 60. I like it even better than the 46 mostly because it's a bit heavier and bigger and handles the breeze a bit better. Go with 5 3/4" on CG and you'll like the way it flys. Saito 125 is a great engine for it. But you know what I use!?!?!?!? It's a great engine also. I mount mine inverted and it seems to run fine. A 16x6 prop should work great with the Saito. Mine keep getting lighter. My last one is 7lbs 12ozs. Flys wonderful at that weight. My most common problem...(no not the landing gear) is I keep breaking the hinges in the elevators. If you can "pin" the hinges back there it will help. This plane does the best rising flat spins I've seen...well if you don't count the Mayhem. I love the UCD60. Funnest plane I own.

gjeffers...Good to hear from you. How ya liking the northern Nevada territory? Still flying quite a bit?

McDaddy...On the 12Z you should be able to balance the elevators by using the above 100% feature in the end point programming. You probably have them at 100%. One of your elevators has a mechanical advantage over the other and is giving you more throw. Also, you may be hitting the end of the throw by hitting the bevels. But...you should be able to max out the throw on the longest one and adjust the other elevator to match by going above 100%. I personally usually go close to 140%. By care examination and programming you will be able to match your throws. The 12 Z is one of the finest radios out there. It's so precise I use it to fly two models at the same time when I get bored.

Thanks

I've never noticed a big difference in fuel consumption between 2&4 strokes. Except... with my Saitos, when I went to 20&30% Nitro, my run times went way up.But that was mainly when I was in 3-D flight. I like 2-strokes because they seem to spool up fast (wood)& they are happy with a lightly loaded prop- low pitch. I didnt have great luck with 4 & 5 pitch props on 4-strokes, I know other people use them but I think it wastes the low end torque of a 4-stroke and might be doing harm.

RE: U Can Do 3D
 

Thanks Gary and Barry and Mixmaster. Yeah, I need to replace the elevator hinges with nylon hinges. I still have to order the engine and some servos for it so it could be a while before I get it in the air.

RE: U Can Do 3D
 

CA hinges are great for cowl reinforcing, I epoxy them in around the screw holes to keep cowl from rubbing the covering off, then I use good strong,long lasting nylon hinges!(pinned or flat)
My .60 Do is still fun even though I have larger planes, doesnt seem to matter to me as long as I'm low & slow, huckin & tail touchin.
Yesterday my engine sagged in a low hover, had no pull out at all, I waited until the rudder was about to touch and then pushed up with a little throttle , the darn thing landed with the engine still running!! HOVERING TAIL TOUCH & LAND-NEW STUNT!!! (OK, it was not planned and its been done before but WHAT A HOOT!!!!)

RE: U Can Do 3D
 

We had another huge turn out at South Jersey Sky Devils Field last weekend, it was a little windy, 10-20 maybe. The Giant Scale guys stole the show most of the day, they can hold them still in hovers even in 10-20 gusts. I could never do that with .60 .90 size planes, Ive tried, I see how they do it by holding the plane at a very high angle into the wind with some up elevator but it doesnt work well for me. Hell, they even seem to stay put when straight up in a wind! I got my 2 cents in at sunset though, only one spectator there to see, got several TR'ing tail touches and kept it DOD for many minutes one flight. I really dont like having limitations but dont seem to be able to work (fly) my way out, maybe the Double Vision will do it.(hope that DA50 runs perfect!!!)

RE: U Can Do 3D
 

it would be awsome to get to see those big birds fly like that on a regular bases we have a guy thats got some 46%ers but cant 3d em it would make it a little hard to get use to though haveing 5 or 6000 hangin on a $100 prop:D hehe
my do is doing great tons of fun every time flying the ep do too it just as much fun has a thing or 2 about it but dont they all fixing to put a ys 110 on the 60 cant wait till it comes in. looks like ill be frizein this winter the old mag 120 is always almost enough leave ya wanting more planes about 9lbs and the mag is no power house

RE: U Can Do 3D
 

I think the do's going to be a whole new bird. Just got my new ys 110s mounted and runin and WOW!!!! why did i wait so long, its going to be killer. havein't had it in the air yet. spoil up is like crazy with a 16x6 and the transtion is like a fuel injucted V8 perfect, and would trun it 9900 easy very rich not even broke in yet think it could get 10700 mabe 11000 going to have to put some more prop on it less pitch and more inches for the do. Sence i don't spend much time at full throtle for 3d keep her around 9800-10000 says shes good up to 11000 though

RE: U Can Do 3D
 

Yea..... yur gonna have fun now:D

RE: U Can Do 3D
 

We have a couple guys fly 35% -40%, 2 of them can bring it DOD whenever they want, one of them does it every time out, I mean DOD-tail touches, drags the rudder in the ground in harriers, even harrier landings, thats ScottZ in my gallery. We had a mid-air 2 weeks ago, not even 3-D'ing, just one of those things that make you sick, 2 planes,maybe 7-8 grand smashing into each other. I'm think about flying this weekend, don't know if Scottz will. I have just finished repairing my Do, was tailtouching after sunset & it was dark, the rudder hit & it cartwheeled, broke in half. This makes think about the Mojo, Fusion, if only the wing tips & stab tips get damaged, then repairs would be easier.

RE: U Can Do 3D
 

:)msn jrd...

As Gary said...yur gonna have fun now.

I had a 100 on my UCD for a year and loved it. I didn't think it could get any better. Then on a whim I put on the mighty 110 and WOW! What a difference. Could not believe it. That's when I got it to start doing the inverted rising flat spin. Everything was "snappier". It was just great. Still one of my very favorite planes.

Mix...I'd love to see you fly. You have way more confidence than me. I bring it down to 6-10 feet and can reliably hover for many seconds but lower....??!?!?!?!? I'm trying but I just can't get there.

I've broke several of my UCDs in two also. They can be fragile. However, I also broke my first Fusion in half. Just behind the wing. Soooooo profiles aren't the perfect answer. Does fly better in many ways than the Do though.

Thanks
Barry

RE: U Can Do 3D
 

Ive got some vids but I dont know how to get them small enough to send via e-mail. They are not much compared to the "commercials" but I can huck a little. You broke the FG tube in a Fusion??? Was it a high speed thing or low & slow "hard landing"? (I hate the "C" word!) One thing I know, there is always less damage when hovering right DOD compared to 10' or 15' up. I've survived 2 flame outs with just broken prop & bent gear when 1' off the ground. Knowing this helps me get it DOD, I just relax & let it come down, if you've done it many times with confidence 10' up, you can do it LOWER.

RE: U Can Do 3D
 

:)I'm not sure really why I crashed my first Fusion. Probably just inattention. I was powering out of a flat spin and got up to a pretty good speed and did an upright "pancake" right in front of me. Broke both wings right at the tube and the fuse at the back of the wing. Tore the engine out and ruined the engine mount as well. It was about a 3/4 throttle pancake job. Hit pretty hard. I'm sure my UCD would have been total toothpicks. I was just really starting to enjoy the Fusion. I think that was about my 20th flight on it. Happened last November (2006). I immediately ordered another one because I really liked it.

One tip when you build yours. Just cut a groove in the side of the fuse for the servo leads. I tried till I was sick to fish all 3 servo leads through the small crooked tunnel and just couldn't get it done. I ended up just "ripping" a groove with my finger to get the thing open enough to get the wires through. On my 2nd one I just opened up the side with my Xacto knife and then just covered with Ultra Coat. Didn't even bother putting the balsa sheeting on it. That was so much easier. And much less frustrating. Also I had a bit of trouble locating and mounting the throttle servo. I used a mini HS85. When it's all said and done I think it's quite a bit harder build than the UCD but not that bad. It's a great flying plane. I've only flown my 2nd one about 20 flights because I've been moving into the gas planes. But the other day I flew glow for a day and had a great time. I just enjoy flying.

Funny how some planes do some stunts very well and not so good on others. The UCD for me is the rising flat spin. The Fusion is the rolling Harriers. The Velox it KE. My Mayhem was great spins and easy landings. The UCD and the Fusion hover about the same (easy). My Wild Hare Edge is the KE Spin and waterfalls. Etc...etc. The other planes will do the same things in many cases but they all seem somewhat specialized. Maybe I've just grown to expect that out of them.

This winter I've commited myself to do a tail touch. I'm beefing up the UCD elevators and rudder (pinning) for the occasion. Some of the guys I fly with fly with skis in the winter off of soft snow. They say it's a no brainer. Anyways, I'm gonna saddle up the UCD and I'm gonna bury the tail in the nice soft fluffy stuff and learn how to do it. I can back down from 20' to ten or so and then nothing works. No matter what I do I can't get any lower. I sware even if I had a flame out it wouldn't go lower. I'm gonna work on that this winter. Normally I don't fly in the cold but my buddies are making me. Anyways...we're gonna give it a heck of try.

thanks
Barry

RE: U Can Do 3D
 

Did the FG tubes in the Fusion break??? I thought they ran the full length of the fuse? Any hoo, if you got another one, they must be pretty good. I have a little experience with profiles, built 2 Su Do Khoi kits, I also discovered that cutting channels in the sides was the way to route wires. I even had the fuel tank inside the wing root area, used 2 long brass tubes to protrude thru the leading edge balsa, then just fuel tubing to the engine. It was only 8oz. so it just fit.( it had fat wings) I loved that little bird, its what inspired Scottz to go 3-D & join our club. Its ironic that I lost that plane in a mid-air 10 yrs ago. I think I read in a thread that some are actually cutting the connectors off, fishing the wires only thru the hole, then re-solder. I can solder with the best of them, but will have to be pretty frustrated to go that length. You're right about each having their own traits, seems like you need at least 2-3 planes to get everything. The Velox is great, but doest do some of the things a Do will, & vice-versa with the Do. One thing about tail touching,there is a point you have to get past, its nerves, & nothing more, you need to get used to seeing your plane near the ground. Do it in steps if you have to, as long as you can hold a hover for lets say 15 seconds or more 10' & do it consistantly, then you know you are ready to get lower. I usually lose it a little each time I come down a few feet, I recover, get it stable, then cut the throttle again, & keep going down. Even if you dont tail touch, just hovering 1-3 ' was a whole new feeling for me, I knew I could touch after that.

RE: U Can Do 3D
 

I'm a very new pilot. The U-can-do 60 is one of the options I'm considering as a second plane. In doing my pre-purchase research, I am looking for mods, particuarly as they relate to the main gear. I've seen some comments that suggest it benefits from some reenforcement. I've done a number of searchs but they return so many threads that its been difficult to find a reference to specific modifications. No doubt some suggests are made within this thread but . . . its a bit long. :D Specific page references within this thread would be welcome though.

RE: U Can Do 3D
 

You can place tri-stock in the corners of the LG formers. You access that area thru the fuel tank opening at the wing leading edge area.
Its a little tight, but I put them in vertically from the ply LG plate to the top of the formers, 4 total. Then I join the 2 formers with a block of hardwood, it can be square, it needs to be about the same width as the LG ply plate. You could use hard balsa soaked w/CA to save some weight. This usually makes the LG strong enough for harrier landings which are pretty tough on the gear. I've had one gear come loose even after the mods, I found almost no glue under the ply plate, not much you can do about that.

RE: U Can Do 3D
 

As for servo connectors, I think one of the easiest ways to deal with them is to remove just the plastic part of the male/ female connector and the plug each pin together individually and secure with heat shrink. Obviously make sure that all of the pins are totally covered so that they can't touch.;) This makes the wires easy to fish and they can be returned to stock by just putting the plastic back on.

RE: U Can Do 3D
 

:)Mixmaster...

I'm not sure what you mean by FG tubes in the Fusion? It has long carbon fiber strips the run the length of the fuse but they are about 1/16" thick and 3/4: wide and there are two of them one sorta on the top end of the use and one towards the bottom. Neither of those strips broke...the wood just broke around them and they just sorta lay there. They are not very stiff when seperated from the wood. But they didn't break. Everything else did. I think they are in the fuse to keep it from flexing side to side.

I can generally hover for a minimum of 30-40 seconds with any of my planes. The Do and my Wild Hare I can pretty much hover as long as I want to. So I feel I'm in control...it's just time to lower it on down. The Fusion I can hover a long time as well. It might be a good canidate to do my first tail touch with.

Thanks
Barry

RE: U Can Do 3D
 

My bad, must be thinking of the Mojo. Usually planes don't break where there is CF or FG support. It doesnt mattter, they will break somewhere eventually. I think I only tail touch with the Do because it s the cheapest plane of them all, but not by much. I'm ready to do it with the Velox, I just prefer to do it when its very light-calm wind, hasnt been much of that lately.

RE: U Can Do 3D
 

I went for a tail touch with the Do and the Velox on Saturday, made it with the Do, almost lost it with the Velox. My muffler was loose but I didnt notice, the engine must have leaned due to loss of muffler pressure, I was only 1 foot or 2 off, the lowest Ive been with the Velox, was just about to go for it when I needed a little throttle, there was no more, had to push down elev & hope for the best. It pancaked a little hard, just bent gear & broke prop-I use only wood to prevent engine damage(crank,bearings). Thats the 2d time I had to land from a low hover, its becoming normal.(the abnormal!) But again, being low can save your bacon!!! My Do looks like a P.O.S. with all the repairs, I'm using any old covering I have left to cover the repairs, but I seem to hover it even better now that it doesnt look so pretty. A friend got it all on his camera, were going to see if we can get it on U-Tube.

RE: U Can Do 3D
 

Finally got one of my tail touches uploaded here in the member video page. Its MixDoHuckNov07.wmv, tag is Mixmaster. Hope you get it playing quicker than I could, waited 15 minutes & still not downloaded! The Velox is MixVeloxNov07.wmv. Its not great, I'll never claim to be a great 3-D flyer, but I can huck a bit.

RE: U Can Do 3D
 

still havent got to try out the do with the mighty 110 yet got every thing ready for this past weekend temps were in the mid 60s and sat morning you couldnt see your hand in from of you face do to the fog! and waited all day and it never lifted and sunday was the same!

RE: U Can Do 3D
 

Sounds like a great combo, probably a lot less than my fat ***** Do with OS 1.08! 8.3lbs! I still like my Do-Wack-A-Do!

RE: U Can Do 3D
 

hello,
Uihm I will fly the UCD with an saito 100 also,but wich servo's do I need?
I prefer to buy futaba's but I don't know wich one are good(I like to buy the cheapest,best servo's for this plane)I'm only 16 and it's already expensife enough,you see..I hope I have enough with 200euro's for all the servo's and accu?Cause my budget is 700 euro's,the plane will cost 209euro's,the engine 300euro's=€200left.I hope I can have a great setup with €700.
I'm sorry for my "bad" english,I'm from Belgium and my mother language is Dutch...
Thanks

Hmm I might use the servo's as in this plane:

They are fine?.

RE: U Can Do 3D
 

iv been flying the do for a good while now bring it every time i fly normally when the weather is good thats once a week at least. upgraded to 4-40 rods everywere and pull-pull on the rudder and i have a hitec hs-625 on the rudder and futaba 3004s everywhere else using 6v bat. and havent had any trouble works great some say it wont but does for me, im not a speed freak maybe thats why, yes i want better servos and will get them some day never had better witch may be why im not in any hurry to spend lots of $$ on them
