Here's a picture of my G-UCD with the ZDZ 40 on it. As you can see it fit very nice inside the cowl.

Very nice picture. The ZDZ40...Is that the ones that Chief Aircraft sell? Did that give you more power than the Saito 180? I have absolutely no experience with gas. When I look at the specs, it doesn't look like you get more power than say with the Saito 180 or OS160. You also seem to gather more weight quickly. Not only in engine weight but also a 2nd battery to run the ignition. Does it seem better for this plane than the big glow engine? I'll probably fly mine with the 160 but if I am not satisfied with the performance, where do I turn? Gas?

thanks
Barry

PS: Completely done except the cowl cut and the balancing.

Barry, yes you can get the ZDZ engines from Chief or direct from Cactus Aviation.
ZDZ also makes a rear exhaust 40cc that lets you keep everything inside the cowl. I think the gas engine made a little more power than the Saito but again the reason I changed it out was the frustration of trying to keep the big Saito from flooding on this plane. I'm sure there are things I could've done to correct the problem, but at the time it just seemed quicker and easier to change the engine out than trying to move the fuel tank or mess with pumps and regulators. Having said that, I think your going to be very impressed with the 160's power on this plane and I haven't heard of anyone having the flooding problem with the 160.

The video on the Giant with the 160 is pretty impressive. I always worry though because I think the videos are mostly at about sealevel. Me, I'm at 4800'. The air here is so thin you can't see it. Scarey. Anyways, makes quite a difference in horsepower. That's one reason I like the YS engines. With their supercharger effect they don't lose so much power up here. But I had a 160OS on a ULtra Stick at 11 lbs a while back. The 160 just played with that think. My projected weight on the Giant is about 12lbs even. If I can keep it there I think I'll have a fun plane. At least I'm hoping so.

I'm anxious to try it. Maybe tomorrow.

Thanks
Barry

rtn9105, Just wondering if the Giant U C Do has the same drumming noise that the 46 has. (?)
I bet that big plane looks impressive in the air. I heard a while back that someone at our field was flying a Giant and crashed it and pretty much totalled it out. On examination of the crash they found that the builder forgot to string out the RX ant. Dohhhh......[X(]

Barry, make sure you have some good altitude the first time you try the crow feature. It took me quite a few adjustments on the elevator mix to get it setup correctly so the plane didn't climb or fall as soon as I turn it on.

RClement, I didn't notice any unusual sounds while mine was in the air.

rtn9105...

I'll have that plane so high I'll barely be able to see it. I have the "Crow" on a variable knob. This should help with quickness. I'll be able to dial a bit in slowly and see what happens then adjust. After I get the mix set the way I want I'll change it to a switch.

This will be the first plane I fly with my 12Z so everything will be scarey.

It is an impressive looking plane. I can't wait to try it.

Thanks
Barry

what is the "CROW"??????, remember im still learning, and can i do it inverted?????

rtn9105...

In the above picture of your Giant it appears the wheels a slanting to the tail. Is that correct? It appears to show the same thing in the manual but it is unclear. My instincts tell me to slant the wheels forward but pictures seems to indicate otherwise. Did you have any nose over problems with that configuration? Did it make the plane easier to balance?

Thanks
Barry

Crow is a combination of spoilerons and flaperons. Sometimes it's called "airbrake" also. You can only do it with planes that have flaps and ailerons. Like the Giant. Like and Ultra Stick. Etc. When you apply the "Crow" the flaps go up and the ailerons go down. Brings you to super slow flight in a big hurry. Many think it helps with "harrier" as well. And it makes landing very slow possible (short field, etc.). It's a fun thing to play with but I don't have that much experience with it. I had it a couple of years ago on a 40 size Ultra Stick. Pretty neat but I couldn't fly good enough to enjoy it. I have it set up on the Giant and plan to experiment with it. Should be fun. That's what made the 12Z a necessity. It programs those kinda mixes very easily. In spite of a long learning curve. Just plug it in like the manual says and "Crow". Other things that are cool about the Giant and the 12Z. I have it programmed to do "Crow" "full span ailerons (flaps and ailerons move as ailerons), I can just use ailerons if I want to without the flaps moving or I can use flaps without the ailerons. All with just the flip of a switch or knob. Pretty darn cool. I can also set my elevators to mimick my ailerons for a super fast roll rate. With 8 servos and a lot of radio I can really do a lot.

The result will probably be a nice crash while I'm fiddling with all the bells and whistles.

thanks
Barry

gjeffers...

Forgot to answer the other part of your question. Yes, you can use "Crow" inverted. An inverted "harrier" would be a good example. Or a very slow upside down landing.

Thanks
Barry

Barry, I guess I don't know if it matters for CG if the gear is slanted back or ahead. It looked to me in the manual and all the pictures I've seen of the plane that the gear leaned to the rear so that's how I installed it plus I thought it made the plane look kind of like a pattern plane.

Barry
We're biting at the bit here to see some pics of the giant in action. Also if that 160 isn't enough, remember Saito has that 220 out and I saw one in action on a giant last fall. All I can say is vertical with an attitude.
I'll stick with the 46 for a while. I picked up a slightly damaged one off Ebay last week incase I need spare parts. Maybe hovers and low inverted passes this year.

Weather here in Ohio is monsoon like for the past week. Three planes sitting here ready and am going crazy. My wife's Kadet LT-40 is almost ready to go. If she does okay with it, maybe a UCD 46 will be next.

hey guys check this out, makes me feel kinda non eventfull now[]

but very good stuff


http://www.geistware.com/rcmodeling/...tics/video.htm

Very impressive video. They will be doing a rolling harrior some day.

gjeffers...

Great video. I enjoyed it. I'd love to try my hand at that stuff. Wonderful waterfalls in the first 1/3 of the video. That's one of my favorite maneuvers. That guy might even be a good RC pilot someday. You know...if he practices.

Thanks
Barry

PS: Busy time at work for me right now. I'm trying to finish the Giant but just can't quite get it done. Haven't flown a thing all week. Got the Giant completely done except the final weight and balance. If I I can keep from adding any weight to balance I will be just under 12lbs. That's good. Very good.

Good Vid Gary.... Is that you flying....

Barry can't wait for the Gaint report...

Well I have the S.T. and "Do" ready and all bat's charging for the Kingman Funfly.. But the
wind forcast does not look good:-((.. Hopefully, the reports are off???? ........ Anyway...

My last outting with the "Do" I thought I "may" have cleared me glitches.... I replace the
medal clevises on the tailwires to plastic ones, So, now no "moving" medal to medal except
for the brackets on either side of the stabs..... But it was a no go:-(((((((((...
Still works great taped to the wing... &*$!&^..........

Most at the field, said the servos is most likely "not it".... They did say the wires could be,
and that sometimes it can be magical once you find what will work??? Any way I repositioned
the rec. so as the end of the ant. wire goes half way into the rudder, Un-zipped tied the wires
at and around the reciever... If the wind is not at the stated 20-30 mph in Kingman.. I'll see
how that goes...

Have fun this weekend People.....

Quick question...

I have a strong running Saito 72 in a profile that has seen it's better days. What do you suggest UCD46 or Mayhem 46? I really don't want another profile. I have the 90 Mayhem and really like the way it flys.

Thanks,
Coolair

Not sure but the Mayhem looks to be a little bit lighter than the U C Do, the 72 might work in it. I think you would be underwhelmed with it in the U C Do though. I have an 82 in mine and it's just about right. Maybe others on here have tried it successfully.

Hey all.... Well no change on my glitch((( Rats!!!! Still works great on the wing....

Was a good day at Kingman Modelers R C Club funfly... The wind did come up, but it was
a nice day and a great funfly none the less.. Great club and members!!! And some Great
food))) Even with the wind it was a blast!! Ohhhhhhhhh....... I lucked out and won the
G3 sim and the add on in the raffle :-)))))))))))))))))))))))))))) Our club made out pretty
good... )14 or so member's made the short trip) I think two or three planes, a hitec 6
channel radio, some parts and the G3/add on that I won. Thank you Kingman Modelers!!

I flew the "Do" once for one circuit and she started glitching real bad, so landed put the
ant. wire on the wing and finished the remained of the tank... She flew good.. I then tried
the S.T got it fired up set it on the runway taxied a bit, but the the YS died. was going to
try it again but the wind started coming up... So I put both up.....

sounds like a good day Ron, a little windy here too[:'(]
i almost did in my 60 size today, was inverted about 15ft off the ground do-ing a end around of the runway about a 100 yards out and lost orintation and choked[X(] fliped it over and jerked up and thank god it was the right move cause i didnt know which way was up[&:]
told the sweetie about it and said that when it does go in im ordering another 46 size and she shook her head ok_____+++++ well i said why dont i just save the 60 size and go ahead and order it and then she woke up and said i have to pay for my glasses first( $500) for sunglasses and clear[:@]

i will get one[

Sounds like you had a fun day Ron. Gotta love that!! [8D]
Gary, It seems your in a tight spot. You have to get the glasses but not a new plane! Hmmmm....... This is complicated indeed. If you get the plane and skip the glasses you might not be able the plane good enough to fly low and inverted over the runway. I hate decisions like that!! AArrrggghhh.....[>:]
By the way, I've been flying my U C Do inverted lately and I'm getting the hang of it. [8D] I'll post a picture someday.

yea rob, i had the hang of it too and scared mysedlf to death today[X(], but i came out smelling like a rose[8D]
dont know whether to worry or not on my next invertprobably not

Rob and Gary... It was a good day, a bit cooler there also... That's bad here in AZ land
when using a tank top outside for 8 or so hrs.. [:@]

Gary.. sometimes the mind/eyes plays tricks huh.... The same thing almost happened to
me... was between 10-15' doing an inverted flat 8 the middle of the 8 right in front of me
I did about three of these, then I thought I would add a snap roll in the middle the first
two was good, but on the third circuit guess I held the snap too long and she almost bit
the dust.... [:-]

Gary, why do you feel the need to tell "sweetie" about your flying OR your birds? Big mistake.

My problem is my shop is on the first floor (we enter the house on the 2nd floor), so I have to time my getting garbage bags with tail feathers popping out PAST the wife. And you can always lie, if asked. "Oh, one of the guys gave me their crashed Can Do. I'm fixing it for him." Never, ever say "...fixing it for HER."

And, Gary, seriously, because I know you fly three or four planes on a given day, on the first flight of a different bird, fly figure 8s both low and high until your eyes talk to your fingers about what the plane looks like at all attitudes. Then, when you get into trouble, flying on the edge, your FINGERS will recall what to do. If you have to THINK what to do, it's too late.
