SUPER TIGRE G 90

Welcome to the wonderful world of 3-D!!! Its exciting partly because of the risks involved,but when it catches up to you,can be a bummer. Good example of why people pay top $$ for engines that must run perfect if you want to keep your plane a while. Ive been there a few times this year,now I start a wall right down on the deck,if my engine quits,the plane only has a few feet to fall,ends up in one piece with only minor damage,hopefully.

Ok guys, I need some advice. I have recenlty read most of the showtime and the 100x postings and find both interesting. I have been out of the sport for awhile and have a Satio 100 and 150 needing a home. All this 3D flying has me excited to try and I was looking at getting both a UCANDO 60 and the Funtana 100X. Am I on the right track and if not what would be your recommendation? Also I have heard of a few putting the Satio 100 in the UCANDO 46, now should I be looking at it instead of the 60? If you do have any other recommendations also for a good beginner 3D plane I would appreciate. One last thing, I am flying with older Futaba radios and am looking to step up to the 21 century and try a computer radio, any suggestion in the cheaper range. I was under the impression that the Futaba 9CAP or the Multiplex Royal EVO 9 are good but man there is so much to choose from.

Thanks in advance, oh by the way, I have been out of flying for awhile but I am using the sim to knock off the rust and even though 3D wasnt about when I used to fly I always did love to fly close, slow and low so I really feel this type of flying is right up my alley.

Either one (Do or X100)would be an excellent start, I'm more in favor of the X100 but the Do(.60) is not too far behind. I think the Do might be a little easier to hover but it lacks the smoothness and tracking the X100 has. The Do will handle most 3-D but needs modifications for strength and 3-D flight. The X100 is far better design,easy to work with,no modifications needed and light wing loading plus the hardware is the best. If you have one of these and a simulator,you will cut down the learning curve time a lot. Either plane will require a mixing radio to get the most out of them,I have used mostly Futaba for almost 20 yrs now,the 8UAF and 9C are the latest 2 I've had. The 9C is best IMO,no need to pay $1,000+ when you get more radio than you can use with the 9C. You could get by with the Saito 100 in the Do(60) but the 150 is best for the X100. The X100 needs a heavier engine up front, I love the OS 1.20 AX but the Sa1.50 will do it. I had a .46 UCD but didnt like it mainly because it was too small, I'm beginning to believe the larger the plane, the easier it is to 3-D.

Guess everyone is done with the Do,its back to page 4 now. I was lucky to be off last Friday,Sat & Sun were horrendous,winds gusting to 50! I took the Do and Giles with me,man was it sweet all day,golden hour all day long.. I ended up flying the Do more than the Giles because of engine and battery problems, its been nothing but trouble for the Giles. I can still enjoy the Do even though I have 2 planes that are supposed to be better,(X100 and Ultra RC Giles). I forgot about going for a tail touch and just had fun hovering as low as possible without touching,I was below 1 ft. many times,did harrier tail touches,then harrier turns back the other way all below 3 feet. I did a bunch of walls so low,the tail wheel hit ground during rotation. My 3rd Do does RH circles without trying to turn,it has really bad pull to the left in harriers and RH's,its so bad that I can give full right rudder in harriers to keep it straight. I have a lot of right thrust in already,probably wont bother adding any more,I can do most anything I want,just have to wait for the best days to Do it.

Has anyone else had a 60 Do that pulls really strong to the left in harriers? I have added more right thrust,had at least 2-3 deg. at first,must be 4-5 now,even my cowl is slanted to the right. It hovers very well,no pulling when its vertical,just in harriers? Maybe its that P-factor thing I dont know much about????

Is the lateral balance OK? Rudder trim set correctly??

Been there,done that, several times. I'm really beginning to believe in that P-factor since its trimmed for level and vertical,no thrust line issues except in HA harriers & rolling harriers. I get my Do up to at least 45 deg. angle of attack for harriers,have to, to get the wing to settle down. Other planes dont seem to need this higher attitude to harrier,wonder if thats whats bringing on the "High P-factor".Funny,I didnt notice it with Do # 1&2?

Sergio,

I owned one ST, that will be the last one! It dead sticked more than the rest of my engines combined, 2 fold easy.

Hi guys

Last Friday i took my U-Can-Do .46 on its maiden flight. I was planning to taxi the field and do small jumps, but when it lifted i flew straight with no trims. So i took it up an flew about 10 minutes, landed och refuel.

This was my first flight ever with airplane, after ½ year helicopter and 40 hours of simulator it was quite easy.

I did 4 more flights, loops, rolls, stall-turn and knife-edge, boy this is fun! Then i lean the engine (OS 70 surpass II) 2-3 clicks. Went out flying again, stood vertical 20 meters of mother earth and the engine died! Gravity stills works and boom!

Think the engine and radio equipment still works. Now i have order a new UCD. Nice flying, i really love this plane!!

see you /Anders

I agree the Do is cheap & poor design(structurally)but I still enjoy flying it even though I have to make several modifications to strengthen & improve flight characteristics. People around here put it down mainly because of its appearance but when they see me hover 1" off the deck,harrier 1" up,walls,RH ect,ect,ect,then its cool.What's really cool about the Do is you don't have to spend mucho $$$ to 3-D,in fact, the low cost helps with the "pucker-factor" which often prevents trying those risky maneuvers down low. It does couple bad in KE but that can be minimized with mixing or the thumbs(practice), and it can dangerous to harrier this plane,drop the nose & it will snap out,any wind gust can knock it out of harriers. I fly it within its capabilities,no down low harriers or hovering when its windy. I fly it a lot in the AM or evening when its calm,do everything 3-D with it.

I agree with Mixmaster...I have the .60 size and the UCD even in this slightly bigger form, does not handle wind too good for hovering / harriers....but still great fun! A genuine RC bargain..would even make a great aileron trainer..so so easy to fly...lands slower than anything I have ever owned. I have had mine for about 2 years now and the film is just starting to come off the airframe..

I'm enjoying my 3'rd .60 Do partly because the engine was free,an old OS 1.08 that was re-built once,I put new bearings in and have been using it for going on 2 years now,hundreds of flights-I hope my new 1.20 AX lasts as long. Since I already had the receiver,batteries & servos from other planes,it was a no brainer,for $160 on sale, a few changes here and there,there you go,3-D for under $200.

Mixmaster...

I'm on my 3rd UCD60 as well. I love the plane. I agree with everything you say. I fly mine a lot in the wind...it's always breezy here, but the wind does knock it around a bit.

I love the rising inverted flat spins this plane will do. Not many airplanes will do this. I'm not sure why the UCD gets a bad rap but I always find myself defending it. It's a nice plane. Period. When you factor in the dollar value (cheap) it's a GREAT PLANE.

I love the way it flys. It has taught me a great deal. The KE coupling is bad and the Harriers are poor but I just don't those maneuvers with that plane. It does excellent hovers, waterfalls, and flat spins. It is very easy to do a rolling circle with and lands so easy it's funny. I was just flying mine last weel. I'm gonna fly it again today if I can get off work a bit early.

My biggest problem as been the rudder. I break it on the hinge line every 10 to 15 flights or so. I have to peel back the covering and reglue it.

I even use the stock landing gear set up now. I just am pretty careful when I land it.

Thanks

They cost less than some profiles.

I have had my UCD 46 for a few years and never felt it was a great 3D plane. I just switch from an OS 70 surpass to an OS 91FX with a 16 x 5 Zinger. After the motor breaks in I will be adding a V30 Perry pump and try the APC wide 15 & 16 x 4 props. I was looking through the posts on this thread for set info. (thanks guys) I set it up per the GP manual with the CG at 6 inches. I had to add 4.0 oz of lead to the tail. Now this plane rocks, it will do the best wall I have ever seen. Snaps up with no climb and will just sit at about 10 feet of the deck. I now can pogo it up a down like it has a DA 50 in it. Rock steady and will knife edge loop as good as my profile Katana.

Using a JR 9303 with 3 flight modes, 3D Max travel & 100% Expo, Low rate with 40% Expo and really low rate set up for pattern with 20% Expo. Set up to the GP manual and the pattern settings are set for just enough to do a good knife edge. I love this setup. I think all along I had the CG to far forward.

Included some pictures of my ARF bashed UCD XL. Covering was striped to re-glue and fiberglass the center section. I wanted to check the construction but found no issues. I did cut the trailing edges square and add a square strip back on to keep the edges straight. I am a big fan of square edge trailing edges for 3D. I can fly it WOT with no flutter. I also added hard-points (dowls) at each control horns. I went with H9 Purple Transparent Lites. I also did my own thing on the cowl cutouts for cooling. Was inspired by the way a hockey goalie facemask looks. I am glad I was not watching Star Wars when I was cutting it out. Had no problem stuffing the 91 in it. It flys like the UCD 60 with a YS110(OLLE from Sweden) in the video a few post up.

Very cool covering, paint, graphics, cutouts, etc. etc. I like it when someone works 'outside of the box'. Good luck with it. Joe

Actually it is the best re-covering and cowl cutting job that I've seen on a UCD. Fantastic!

That's why I don't use the stock tail wheel & hinges,especially if you plan on some harrier landings. For some reason I dont try flat spins much anymore, probably because this Do is a little nose heavy,one thing I like is inverted flat turns with the rudder maxed out,the turning radius is as small as 10' circle and I let it get very low. A rising flat spin is something I've never done,I've seen what it looks like,its crazy! Have you tried spoileron mixed to elevator with 45-60 deg. throw? I know this made a huge difference in how my plane harriers. I did have to add tri-stock to wing trailing edges & add in additional P-mixes to get the throw but looking back, it was worth it, it harriers quite well and looks cool because of the high angle,looks like its almost standing up. I fly mine in wind too but dont like to do harriers & hovers,too easy to get knocked out. I use a landing mix on the really windy days,a little up-spoileron to keep it from ballooning up on final,have it reverse-linked to elevator(when up elev is pulled,spoilerons drop proportionally). Let them talk,the flying speaks for itself! The Do rocks on!

Best looking Do I've ever seen-nobody messes with the Do!!!!!

How do you guys do the rising flat spin? Are the control inputs the same as in a regular flat spin, but with higher throttle?

I dont do that but can you imagine starting one down on the deck and then go up??!! Might be a new 3-D wave.

The rising flat spin is hard to do. I think the main thing is to have a very low wing loading. The way you do them is the same as an inverted flat spin. Then you manage the ailerons, rudder, elevators and throttle (about everything I guess) and the plane comes to a full stop while spinning, (pinwheel) At this point you feed a little more down elevator and pick up the throttle. The plane will pick the nose up just a bit and begin to rise. The challenge is to manage all the surfaces because the plane really wants to roll out the flat spin. With the UCDs and the Mayhems this maneuver is pretty easy but you do have to really juggle the sticks. I was able to do it moderately with my Twist. Those are the only planes I've been able to do it with. All others seem to just roll out of the flat spin. My AirWild is close. I've only tried it two or three times and it seemed like it would do it with some coaxing but I was unsuccessful. I will keep trying with that plane.

It is my all time favorite maneuver and looks sooooooo cool when you do it. On a calm day I'm brought the plane down to about 15-20' from the ground and was able to get a rising flat spin up to 50' or so. Most of the time I can go up 10-15' before the plane rolls out. Sometimes adding spoilerons helps. Sometimes I'm not sure it does. But I really have to be on my game to do them.

It's interesting that the UCD is so good at this stunt. Yet it lacks in many other areas. Kinda neat though when you can do something that the many thousand dollar planes can't.

Thanks

Its easy to forget other "old school" stunts the Do can handle but most others can't, like square loops, I use elev-flap mix(up elev=down flaps)for this and can start a loop (start on up-line)down as low as 15 ft,it does very tight loops and the corners look almost square. I can do diamond shape too,all very low. I dont hear too many posts about its slow HA KE but the Do again does this like no other I've seen,very slow and holds at 45 deg. angle which makes it easier to get down low,I've been down to 3' for a while doing this. Its just a unique plane IMO in appearance and flight. Even my good friends at the field tried to talk me out of flying the Do but after a time they all relented,no one else is doing everything that I'm doing. There are some better flyers at my field, they mainly fly giants, but none of them TR down on the deck,I've never seen anyone else drop 10-20 feet while TR'ing and still maintain vertical. Sometimes when its gusty I have to quit flying some of the 3-D stunts and watch the giants continue to do their thing, but thats OK with me, I cant afford 35-40%'ers so I'm content waiting for my "window" to do it all.

I actually deliberately unbalanced(laterally)my Do to see if that would stop it from pulling to the left in harriers,added more weight to the right wing tip,it didnt change anything,in fact it didnt even need any ail trim to my surprise. I can turn it but it needs max rudder momentarily and often. I,m dealing with it and it does a nice rolling harrier circle to the left without trying to turn,going the other way is harder,requires pushing down-elev when the wings are almost in KE. I can turn it as it is but makes it on the edge of a snap. Guess that's what 3-D is,always on the edge. I still take my Do along with the other planes,it was a little windy last weekend but I managed to get DOD a few times in hovers and harriers,it really moved fast with the wind,cant imagine a tail touch like that,it would cart-wheel.
