Robert, don't think your going to get an answer to that. Of the thousands of posts here, this may be a first on a tail heavy UCD. They are notoriously nose heavy, even with the recommended engine size. I've got a five cell battery half way down the tail to balance, tank on the CG and all the radio gear under the wing bolts. Joe

ive had 2 they were nose heavy,, had the battery as far back as i could reach in the fuse

BTW cumn thru Im still saving for the YS110

Save those pennies, as it will be the best money you have ever spent. Good luck, Joe

Just got off the phone with Tony, THE manager at HiTec. I had one of their 90 oz torque servos in my U-Can-Do 3D .46. The rudder servo stripped in the air! Tony absolutely refused to send another servo, oh, yes, would repair the servo for a fee, plus I would have to pay shipping both ways! The cost would total about $21 for a $25 servo!! Tony pointed out, and I saw is with my own eyes, that in the fine print of the warranty, there is NO WARRANTY on gears! Buyer Beware! You strip it in the air, even if it is the right servo in the right plane, doing the right job, your problem!! I have used HiTec servos for over 10 years now, and I have never had this problem, but I did not get a warm fuzzy feeling talking to HiTec when their response is, not our problem!! I was hoping that the company behind the product would be more supportive and helpful in this situation.

not here again dude this is a bad way to start out posting nobody wants to here the bad already know now if its bad thats new now I'm listening

Heres a question for ya guys. my u can do will be here shortly..

I have a Electron 6 with a JR 9303 transmitter.

My question is this. seeing that I only have a 6 channel rx, i was wondering how i should wire it. should i use y harnesses on the ailerons or on the elevators?

what would be benifits/drawbacks of doing it either way.. or is there a way that I can plug all 6 servos into the receiver and still somehow be able to plug the battery in?? Can a person Y harness say the battery and another channel servo to channel 6?? how does everyone else have theirs setup. I am new to plane setups.

Do people mix their elvators with their alierons? if so would you want to mix it for normal flying or for stunt flying?

thanks

Great flying plane.We have four in our club.Will fly unbelieviably slow.All of our plane have a Satio 91 or 100 installed.WATCH THE SPEED!Flutter is a problem.

i dont know about all that mixing stuff but i did y my ailerons and y my elevators with a servo reverser and also go with 4-40 or carbon fiber pushrods because the stock rods oill come back bent.also ive almost lost my rudder and an aileron due to ca hinges and was lucky to catch them just before they fell off. so i replaced them with dubro pinned hinges and they last. great plane choice to start with though!!!!good luck.

I start my build on it tomorrow.

Puttin in a Saito 82.

Has anyone had luck with the 15X4W props??

With the 9303 you can use all 6 channels to operate each aileron and elevator half along with rudder and throttle. You can mix any channel to any channel in the device selection options

hey alot of you guys run saito 100s and i just found metal in my crankcase and shipped it in for warranty after approx 26hrs of runtime and think that is kinda short, how many hrs should i expect? how many hrs have you guys been getting? ive been running power master 2020 and coolfuel 30 heli and everyone agrees these fuels are ok so i cant figure out why the short runtime. i ran 2 gal fuel thru per instructions realll rich for break in so i guess you can say im fishing for answers. also does anyone know if they will void my warrenty for using these fuels since the book recomends 10-15% nitro.

thanks gary

G'day mates. I am a newbe to the universe so lets see how this works. I read in earlier posts that ucdo's had some damage out of the box. Well I have just received my second wing with basla bits rattling around inside it. Tower are sending me another one. All boxes looked perfect. This time I asked if someone could actually check before they box it up we will see.

I had fuselage damage out of the box. Looked like someone had stepped on the fuse right in the center of the wing saddle. The former over the center of the wing was totally broken out and floating down in the back of the fuse, and the aft wing former was split in the center. There was minimal cosmetic damage to the covering and I reinforced the sheet balsa which had some cracks. I just repositioned the former and epoxied it back in, braced the split former and added some 1/4 in. balsa stock reinforcement from side to side where the crush occurred. I suppose I could have ordered a replacement fuse, but I was so anxious to get it in the air I just decided it would be quicker to repair it than to wait for another fuse. A guy I know also had problems with broken ribs in the wings, but my wings were fine. I had a problem with a Great Planes Super Sportster wing (landing gear kept folding up on touchdown), and they sent me another wing no questions asked.

ive had 2 ucds also and they both rattled and i just chalked it up to building leftovers and maybe chads from where they cut out for servos but they both passed the "feel" test and no formers were broke so you might be over reacting unless you felt some breaks in it.

I know what you mean about wanting to it in the air. I just couldnt bring myself to go ahead with the biuld not knowing where that balsa came from. If the wing failed in flight I would probably broke my leg kicking my self in the A. Putthing an os91fx in mine and 645's on the control surfaces. How does yours fly?

I also have an OS .91 in mine, and have Hitech 425BB's on the elevators and ailerons, 945 metal gear on the rudder. I really like the way the plane flies. I've got issues with knife edge tending to tuck toward the belly, but I think as my skills and time with the plane increase that shouldn't be an issue. It is really good hovering, but has a heck of alot of wing rock in harrier/elevator type maneuvers. You have to really be quick on the sticks to keep the wings level. Earlier discussions in this thread have indicated that others have had the same experience. The OS .91 is very good in this plane, but I wouldn't say mine "rockets" out of a hover. But, I'm only running 10% and also am using an extra head gasket to reduce preignition, which probably reduces power too. Even so, it will go vertical on takeoff until I can't see it anymore. All in all, I'd say it's definitely a keeper.

Could be "over reacting" but all the cutting is done before they cover them so I figure that it had to be broken after covering. Just dont want to take that chance.

what about the string inside used to pull servo leads thru? they rattle also. im just giving ya something to think about, im really not being a smart#!$. its just that both mine rattled like crazy also and im still flying #2 for last 3 mos and its still fine. i dove #1 straight into the rocks out here inthe desert with the tail being all that survived. good luck lal.

damaged wing up date, SUCCESS! Third time was the charm, wing with no brocken parts rattling around inside. But now that I have the wing I was about to install my 2 new 645MG's and thought I should check them before mounting. 1 worked great the othe ground to a halt in a couple of seconds then I could smell something burning. Switched off, unpluged, cursed, one servo was hot enough to cook eggs on. I don't know which flying god I have p*#@ off, but he is. Hope to have all this bad luck out of the way before next weekends maiden flight. Fingers crossed.

Hey i am wondering what would be a better motor to run in a ucd .60 a o.s91 or an saito91 and which would pull out a hover better

4 Stroke?? the saito 100 16x4W or 16X6 which ever suits your taste

the YS-110 is BEST choice but get on the waiting list they sell out faster than i dont know what.. if they are coming in on a tues. at 8:30 they are gone on tues at 8:30:01

I wolud go with a saito 100 for good 3D preformance with APC 16x4W. I had a saito 100 in mine running 30% fuel for good pull out power. I few it so often I wore out the motor and installed a OS120 in its place. A .91 would fly it good but if your looking to do a lot of 3D you would be much better off with the 1.00

Thats basically my story. The UCD .60/Saito 100 is a good combo, but I feel the engine life would be prolonged in a sport model. With the UCD being my first 3D plane, I discovered just how much more you rely on flying off the prop wash, which multiplies throttle time and engine use. I wore out the Saito in one season. Instead of a larger Saito I went with a YS 110 and never looked back. Joe

hey joe, glad to see your still around, i just finished wearing out my saito 100 (new years day) and sent it in for warranty and they said it would be $157.00 and i said why? and they ssaid my bearings were rusted and they dont warranty maintanance problems.and i convinced him that i did everything right as far as running it dry and oiling it and they went ahead and repaired it . whew!!! so saito warranty is good with me but i was worried.good to here from ya.
still on #2
