Just doing a quick search, all are longer or within 1 inch of each other, wingspan-length. All are 3d planes.

The gear is simple forward the gear will flex back wards like yours will pull the front of the block first and out it goes

*** were is the Kaos in the u can do 3d? Farthest you can get from a pattern plane Modern pattern planes are square not old school.

First of all, I'm quite surprised you took the time to post those links, and since you put a smiley there, I guess you're not pissed off and are enjoying this debate. 2nd, the BANCHEE has a greater wingspan than length, so it doesn't count, I also wouldn't count any of the foamies, since their design, flight envelope and lack of airfoil is completely different than most other larger more common models, You also can't count bi-planes, since their sole purpose was to have shorter wings for more maneuverability, totally different design catagory. 3rd, None of those have a forward swept gear, which was the whole point of this to begin with.

I will admit, I am surprised that so many of the newer 3D models are so long in proportion to the WS, I guess since torque rolls became so popular, the designers tried to help us out. I suppose there is a distict difference between a 3D model and a true fun fly design, they are generally very short, and rather old school, but that's what I was thinking of.

So, we tend to agree on the wingspan vs. length debate, but are you still saying that the U Can Do does not remind you of a pattern plane? Let's take a look at some key "patterny" features: Very tall fuselage compared to it's width, Long skinny nose with lots of length ahead of the gear (and wing) , Long tail moment, forward canopy, wide chord rudder, tall narrow cowl with very prominent chin scoop and little or no cheek cowls typical of aerobatic models, and the swept back gear. Do not look at the airfoil, I am only referring to the basic shape

Going to be getting mine together this weekend with a ZDZ 50!! I'm going to have to do some mods to the lower firewall area and the cowling but it looks like it's going to work out fine and should be tons of power. I just didn't see the sense in underpowering this bird with it's intentions and there is definetely plenty of wing area for the weight.

How about some opinions on radio setup from those that are flying them. I'm particularly interested in the flap and spoileron mixing, am I understanding correctly that the spoilerons are supposed to go up not down with up elevator?? Are you guys running the flaps separate or mixing them to move all the time with the ailerons

thanks

My Feedback: (35)

I have my flaps setup to be separate from the ailerons but when I flip a switch it links them together and gives full span ailerons.

Post some pictures of your ZDZ 50 install, I'm really thinking I'd like to replace the Saito 180 on mine with a gasser.

I have a ZDZ-40 on mine, there are some pics in this thread [link=http://www.rcuniverse.com/forum/m_2998674/mpage_2/key_/tm.htm]http://www.rcuniverse.com/forum/m_2998674/mpage_2/key_/tm.htm[/link] It flies very nice, tons of power on a 21x8 , but still lands like a feather. I have my flap-aileron mix on a switch too. I use only the outboard ailerons for normal flying, it rolls just fine like that, then I use the full span ailerons for hovering, you can get good control with those large flaps right in the prop wash. I also have the flaps mixed to elevator for flapperons, I like to land with the flapperons, you can drag the tail first, then bury the elevator to get the flaps to drop, which really slows down the nose from just plopping down. This thing is a blast for touch and goes. I have spoilers (ailerons up) on another switch but I hardly use them, planes like this just don't harrier well anyway, I need to experiment with the amount of spoiler, maybe I can get it better.

I flew with a DA 50 and had a blast with all the extra power. I would recomend that you keep an eye on the fire wall for cracks. A 50 in this plane is a monster. I set up the plane with full length Ail. 2 servos per side with a y-harnes I also changed the control horns to bolt type so I could adjust the length to get the ail halfs to move the same. For harriers I mixed 60% spoilerons and the plane did them great. Only a small amount of wing rock. I was able to do Harriers down the runway draging the tail wheel.

BBriBro, I see that you used the rear exaust zdz 40 with very good results, do you know if the side exaust zdz 40 would fit inside the cowl as well?

Just wondering if you saw my video in the review as mine will harrier all the way to the ground.

BBriBro

My Feedback: (2)

Well, I can get it to harrier, but it just doesn't "lock in" like some other airplanes, which makes it hard to keep consistent and isn't very confidence inspiring, feels like you are always having to work it to keep it in the harrier. yes I saw the video, the harrier at about the 2:30 mark looks good, very steady and a high angle of attack, you're photo titled "harrier" isn't really in a harrier in my opinion, the wing is not stalled, and very low angle of attack. I make all my landings with a higher angle of attack than that, and it's still "flying" I carry a little power in the flare so the elevator is more effective, and you can really get the nose high without a hint of tip stalling. will yours "elevator" decent ? Mine won't pitch up enough unless I add power, and I have a ton of throw, I might have to move the CG back.

Sure the engine will fit, but the muffler won't.

My Feedback: (512)

Yes it will elevator very well, I think this is plane does it better than anything else I have flown. There was another guy that couldn't get his to do it at all either, maybe some variences in the kit or something? Mine has to have the spoilerons mixed to do it though otherwise the wing does rock. I can start up high, dive it and then hit full up elevator and it just basically stops in the air.

I'd like to hear about some of your setups on the flaps and ailerons. I hooked mine up tonite on my 9Z and currently have the ailerons on their own channel mixed as flaperons and have the flaps each plugged into a separate channel on a aileron pmix. I'm not sure if this is going to be the right way to go, I'd like to try spoilerons also.

thanks

I finally finished my Giant U-Can-Do and flew it last week! It flies well with the Saito 1.50 however I didn't really push it on the only 2 flights I had. This things flies so easy and so slow it isn't even funny. The landings are almost as easy as the trainers I have flown. I did end up using the Glider programming in my 9chp and it works great. I almost put it in trying out the mix that puts the flaps down and the ailerons up though. I have it on one of my slides to make it proportional and I hit it all the way up which stopped the plane dead and nosed it straight up. I forgot to add in elevator! I am going to put it on a switch now. Otherwise, all is well. Love the plane and would recommend it. I did try some hovering at a safe altitude and it was fairly easy with plenty of power. I still have to get the Saito tuned a little better as I am only running about 8400 rpm at full stick and I could be at 10,000. This is my first 4 stroke so I am a little green in the tuning area.

You know that when you activate "crow" or "butterfly" you need to mix in some down elevator, that is also one of the preset parameters in the BFLY programming. It took quite a bit of down on my UCD, lot's more than on the ultra stick. On my radio it took 2 mixes, the butterfly mix only adds down elevator to the elevator channel, (even with the link on) since we have 2 elevator servos I had to make another mix with offset as the master and ch 8 as the slave, and then make it the same amount as the BFLY mix, that way one switch activates both mixes, works like a charm, I can descend vertically over the numbers, and it will stay on that line, without pitching up, until I'm ready to flare.

My only question would be, how do you get the butterfly mix to turn off wen you do not want to use it? I tried using it, but it links to my throttle/airbrake stick adn I don't want it active all the time. I knew that I needed to mix in eleveator, I just forgot to do it. It does seem like it will need a lot of it, because my plane stood up straight and stopped. There were several tense moments until I could get the slide back to center and climb out. I like the butterfly because it is proportional, but I just don't want it active all the time. Besides, this thing lands so easily, I would only need it to come in screaming fast and lay on the brakes for a cool factor type of thing. How did you program it? This was almost more complex than programming my helicopter!

BBriBro

My Feedback: (2)

Mine is on a switch, the one that is normally used for elevator dual rates, (top left, front of transmitter) that switch turns it on or off, and the throttle makes it variable, so you can do a landing with full crow, then when you add power for a touch and go, the crow retracts, you can do touch and goes like that if you want, just leave it on. You can also deactivate the function on the throttle stick if you don't want to vary the amount with the stick.

I'm in the process of mounting a 40cc gasser on my giant UCD. Do you guys think I need to beef up the firewall for the gasser install? I was thinking the easiest would be to just glass the inside of the firewall and down the sides of the fuse.
The manual says the airframe will accept up to a 41cc gas engine but I just don't know if I trust an ARF to handle a gas engine.

Well I've got mine all done with the zdz 50 installed. Test ran the engine today and had a ton of shaking at idle. Have any of you guys been flying big cc engines and how well is the airframe holding up??

BBriBro

My Feedback: (2)

My ZDZ 40 shakes pretty bad at idle. I have the low end rich for a decent transition and it makes it shake worse. So far the only thing I've noticed is the dowel in the front of the canopy wearing away pretty bad from the bulkhead.

i talked to a guy about his zdz shaking at idle. the plug cap was screwed up and making the idle real rough.

rtn9105

My Feedback: (35)

mrbigg, what was screwed up with the cap? What did he do to correct the problem?

I put the first flight on my Giant UCD with a ZDZ 40 last night. It did have some shake a real low rpm but not a whole lot more than the Saito 1.80 had.

I took out the OS 160 and put in a Evolution 35 gas engine and flew it last weekend. It definatly feels heavier now that it is 14 pounds instead of 12.5 like it was with the OS. I couldnt get the cowl on so flew it without. It had about the same power (pullout from hover) as the 160 but this engine is new and not broken in yet.
