RE: U Can Do 3D
 

My 60 Do would lock in harriers provided the wind was 5-10 or less,all the mods and mixing helped some. I did look at the Velox,felt it was too pricy for an unknown. I really wanted the 50cc Velox, but has been sold out for months now. I'll most likely fly what I have for now,reflect on the past later. Any experience with the Seagull Harrier 90?

RE: U Can Do 3D
 

:)MIXMASTER...

Yes, I forgot, I had the Seagull Harrier 90 also. Everyone of the above planes I flew with the YS110. I have 6 of those engines now. The Harrier was pretty nice. I liked it. It was pretty tough and flew very similar to the UCD60. My biggest complaint was it was very hard to see in the sky. It would waterfall excellent and flat spin pretty good.

My other complaint was it was very much like the UCD and not enough different. So...I like the UCDs so I gave that one away to a friend. But it was a nice plane. Wouldn't KE any better than the UCD.

Thanks
Barry

RE: U Can Do 3D
 

Damn,6 of those could be 3 Da-50s! How did they all run,I heard and witnessed too many problems with the 110 to bite.

RE: U Can Do 3D
 

:)Mixmaster...

The YS110 is the "best in class" if you can get them to run. After my first one or two I finally figured out that the regulator is almost always the problem. I ended up opening all of them to 3 turns and that helped a great deal. They are funny engines. They are difficult to tune (I don't care what anybody says) but when you get them right they are the most reliable. (I don't care what anybody says) And when it comes to performance they make the most power of anything in class. The higher in elevation you are the more difference there is. That is because of the supercharger. It doesn't lose as much horsepower as the air pressure gets less, hence more power at higher elevations.

I'm fond of saying, "Ahhh.....YS. You love 'em till you don't."

If you wanted to try one I wouldn't be afraid. Now that I've got them figured out they are my engine of preference. They make these 90 size airplanes sooooooooooooo sweeeeeeeeeet to fly. The power is truly amazing. And with the pump you can put the fuel tank on the CG which keeps it flying the same as you use fuel. Amazing little engines.

Oh, I have a DA 50 too. And a EVO 45. I'm building a gas plane as we speak. (Great Planes CAP 232) But I'm stalled on it. I think I"m gonna stay with glow. As I look at it the wing loading is always higher on the bigger planes. With my UCD I'm about 15 with the gas plane I'm gonna be about 27. That's a big difference. I gotta believe it will not fly as light as the UCD. (I don't care what anybody says.)

Thanks
Barry

RE: U Can Do 3D
 

Yep, I loved my YS45,toughest,longest lasting little 40 I ever had. The throttle response was perfect due to the carb and regulator. That low end regulator screw on the 45 never gave me any trouble,I just left it flush with the body & it worked. The wing loading factor on larger planes changes even though the numbers go up,I read an article somewhere about that. I know from watching them fly they dont look any worse,the guys that fly them here swear by them(33% & up). The way I feel now,I'm going to fly the Giles(77" wing,12lbs)and Funtana 100X and see how I feel about them. In particular the Giles,if bigger is truly better,I should notice a difference.

RE: U Can Do 3D
 

I have to move on and get over this crash. I am the always the first one to admit when I goofed up(theres been plenty of that lately) but this one is a mystery to me. I tested everything before I scrapped the wreckage and it all looked good. I *hit canned the rcv & some extensions since I'm not sure what failed if anything,it may have been a hit,rare for me, but its possible. The best thing for me now is to forget about it,if it was another dumb thumb,that would be another story but since it wasnt I did what I had to do-order another plane!!!!! Chip Hyde Vision for $425, I think its a steal at that price and I've seen one fly at my field and it looked very good to me,at 15.8 lbs with DA50-oh yeah!!!! I feel better already!!!!

RE: U Can Do 3D
 

Its been 2 weeks,I'm enjoying flying a new Ultra RC Giles,building a Funtana X100,but I miss doing hovering TR'ing tail touches in the evening, and all the other stuff. I'm not there with the Giles yet,I should get there with the Funtana eventually, but I just might get another Do just to keep around. If I dont get to do all that DOD 3-D with the new planes,then I'll have to get another one.

RE: U Can Do 3D
 

I just finished a Ucando 60 with a YS110 installed in it, and I am at a loss at how to balance this beast. It is very nose heavy at 5 inches back from the leading edge. I even put the battery (1100mah 4.8) right in front of the tail wheel and it was still nose heavy. I'm sure a 6volt would help, but I don't think it would be enough without adding a bunch of lead weight to the tail. I have never had a plane that was this far off of balance before. The only thing close to this was my Ucando 46, and it was the opposite with a YS63. It came out tail heavy, but I was able to balance it with a 6volt battery all the way foreward. I know that many guys put YS110's on these things, so please share with me any tricks you have figured out in balancing the plane.

RE: U Can Do 3D
 

:)That's kinda odd...Mine balanced at 5 5/8" with the 4.8v battery about 1/2 way between the back of the canopy and the tail wheel. I have servos that weigh 2.2 ozs each. Are your servos lighter than that?

You probably wouldn't have to add very much weight to get it to balance. If you're at 5" back right now you are in the "envelope" 5 5/8" is about as far back as you want to go. It will KE better at 5". So...it depends a bit on the type of flying you want to do. It would fly very nice at 5" but hovers a bit better at 5 1/2 or so.

Anyways...This is my favorite plane. The mighty 110 made it the perfect plane for me.

Thanks
Barry

RE: U Can Do 3D
 

Its a no- brainer, I have a good engine,receiver,batteries,servos,I have to get another Yo-Can-Poo. There's just too many things I could do with it that nothing else can match. I don't care what others think,I had more fun with that plane and I think I went further than anyone else has(in my club) when it comes to TR's DOD. I've heard maybe one other guy could do it with a foamy. Ive had the Yak,Showtime,Giles,none of them hover as easy as the Do,the rudder & elevator responsiveness in a hover are more than enough to correct any angle of error. I know I'm going to hear it "that plane has ruined your ability to fly real planes". They always seem to over look the "fun factor". If its "presentation" they want, they can have it, that doesnt give me the same thrill I got from hovering & TR & tail touching. THE DO ROCKS ON, BABY!!!!!!

RE: U Can Do 3D
 

:)Mixmaster...I'm with you on that last post. It seems the more planes I fly (almost all of them cost more than the UCD) the better I like the UCD. It is an awesome plane. And it's better than most people think it is. A lot better.

I've had a F90, Showtime, EF Yak, Harrier3D, Velox, and some others. I've liked them all, well except the Funtana. But for overall fun, I like the UCDs the best. I'm on my 3rd UCD60 and 5th UCD46. The other planes generally will KE better and maybe Harrier better (depending on the plane) but the UCD is their equal in every other area and is more fun to fly and is easier to hover, TR, Waterfall, rolling circle, etc.

I love the UCDs.

Thanks
Barry

RE: U Can Do 3D
 

Sorry Barry, I guess I didn't explain my situation concise enough. I havn't flown the plane yet. When I set the balance machine at 5inches and put the DO on the pads, the nose drops. I have played around with the battery possition, but have not set any extra weight on the tail yet. I always try to balance without lead and am usually succesful, but It looks as though I will have no choice with this plane. BTW my servos weigh 1.44 on the elevators, and 1.5 on the rudder.

RE: U Can Do 3D
 

:)msouth12...

Sounds like your servos are collectively about 3ozs less than mine. That probably would account for all the difference. This plane is very long and has a lot of leverage out there on the tail. I'll bet the extra 3 ozs I have in servo weight is the only difference.

The good news is your plane is probably 3ozs lighter than mine for the same reason. So adding a couple ozs of lead will probably not hurt it. Or you could go to heavier duty servos. I use the HITec 5645 on this plane. That's on the rudder, I us 5625 on the elevators.

Thanks
Barry

RE: U Can Do 3D
 

Barry, you said the 'L' word. [&o]

msouth12, I had some lightweight digitals in mine. What I did when swapping out the S100 for the YS 110 was to mount the engine as close to the firewall as possible. The cowl still works with the engine aft of suggested.

Radio gear in the aft portion of the compartment.

My battery position ended up 1/2 way down the tail. 5 cell 6V on a cusom mount to stand it on edge due to how narrow the fuse was back there. All accessed by a hatch on the bottom.

I think that the 4/40 linkage in the tail helped a bit as well. It can be done without the polution of 'lead'. Good luck. Joe

RE: U Can Do 3D
 

If we had a 3-D only contest at our field on a day with light wind(no foamies), I think my Do would stand up to any rival plane,even gassers up to 40% with flyers of similiar experience. If precision was the game,the Do would sit. I have to make quite a few mods,but they not that complicated or expensive,and I like mixing. No other plane can do some of the bizzare stunts the Do-Can-Do(sorry),like wheelie hops to a hover. I do understand the "presentation" idea, I hear that said a lot about the Do,guys wont fly one because it "looks funny","doesnt present itself well". Well who are they "presenting" it to? Its always the same group of guys out there,we all know each other,none of us go to contests. Granted the 40% will probably steal the "show"(if there was a show here) even if I matched every move. I haven't forgotten that its a HOBBY,as in have some FUN,ENJOY yourself,indulge yourself into whatever suits you. OK,sorry for the ranting,I'm done with this issue,the Do is back and I'm gonna go have more fun right now,oh,have to build it first.

RE: U Can Do 3D
 

Mix, they are all just jealous. Good luck with the build. joe

RE: U Can Do 3D
 

Hello i have got a new UCD60 and i want to learn doing 3D with it. I have to choose the engine to mount. I see that os 91 fx has the right power for it, but i see also os 120ax is it too much powered?

And the os 2 stroke needs pump to run right or not with UCD60?

I looked at this post for answers but it's too much long...

Many thanks

RE: U Can Do 3D
 

I've had a Moki 1.35 and OS 1.08 in 2 UCD's,both flew well,the weight was not a problem,so I think the OS 1.20 would be fine and if I remember correctly,its lighter than the older OS 1.08. They do fly OK with the 91 too,but if there wasnt too much difference in weight,I would go with the 1.20. Is there is only 2-4 ounces difference,the 1.20 will be best for hovering. If the fuel tank is mounted behind the firewall,no pump or pressure system needed. I mounted over CG,then use a fuel delivery system.I use nothing but Cline,they work well from a .40 up to 1.60.

RE: U Can Do 3D
 

Ok fella's I got it balanced at 5 1/8 by putting the battery half way back, and adding 1 1/2 oz of weight to the tail. So that is not nearly as bad as I thought it would be, and I guess maybe I panicked a little the first time I set it on the CG machine. Like Joe said there is a lot of leverage at the end of that long tail. Thanks again guys, hope it flies as wonderfully as 46 does.

regards,
msouth

RE: U Can Do 3D
 

That is odd,my 60 w/OS1.08 balanced to 5.5" with battery approximately where AcroJo has his. I used Hitec 635 servos in the tail and 6V 1200mah. I'm sure the 1.08 is at least 5-8 oz. heavier than the YS110. I put a pull-pull rudd servo on the bottom of fuse,half way between battery hatch and tail. Yours must have all the heavy wood up front? They are very light and weak in the aft section.

RE: U Can Do 3D
 

I dont know if they were jealous then, but they will be soon. Several guys quit flying during the summer,they havent yet seen the tail touches,T R DOD,and walls where the tail hits the ground as it rotates up. While they They've heard about it from others,but from their remarks,they dont believe the "witnesses". Only one other flyer saw me do a tail touch,several others watched me TR 6" off the deck several times. What they have done is essentially discredited the witnesses. Its getting to the point where I dont give a damn what they think,the more I tell them about it,the less they want to believe it,guess they dont want to hear it. I dont think I come across as a bragger,just excited about it. Its strange that I got "hit" at this time. While they were off,I kicked it up a notch from practicing more often. I hope I can get another one together with the same thrust lines,incidences,Cg & all that so it flys the same. Wish that Giga Hz Spektrum was available now for larger planes,I wouldnt have to worry about getting hit. I thought of Ham band, but think I would need a license for that.

I need to change my UCD 60 engine mount. Anyone knows if the Great Planes adjustable mount 0.6-1.2 is the correct part? Thanks

RE: U Can Do 3D
 

Mike, that is the correct mount, and the one the plane comes with. Part #LXJ773
