Hey Jack, Lots of questions. I had a couple of Twists and I'll have to say I personally had a hard time flying them. Maybe I just wasn't good enough to fly it but I found it to be twitchy. Barely any inputs and I was all over the place with. Again, maybe I just didn't fly it right. I now fly an OMP Katana profile and fly it very well. I sometimes wonder if it's me flying it. I only mention that because they are both short, quick turning planes and I fly the Katana like a bandit. Now the U C Do, that's a different story. I find it much easier and funner to fly. (by the way, before I forget, I flew a U C Do 60 with an OS 91 and it was a dog too) The 46 with a 82, 91 or 100 is a great plane. Lots of fun with that combo.
But there are certainly a bunch of people that do well with the Twists. Is there anyone where you fly that has a Twist that you can try out?

hey there jack211, your right about the 60 size being a dog with the 100, but that is after i used it to learn to fly after my trainer, it was a great 2nd plane,then i moved to the 46 which was a lot quicker and agile with my saito100 and i mean i loved that plane(and will get another) but i know nothing about the twist and will never buy one because my buddy Rob says its twitchy and im to old for that,wait a minuite i have expo, oh naw forget it im not getting one, but if you want a real fun plane get the 46, imo its the best so far but then again ive not been that far in this game yet but im going fast
by the way ive flown in sustained winds of 45 mph, this darn desert is always blowing[8D]

Hi all!
These weekends crashed my ucd60
due to radio interferience. Nice plane. Two seasons of awesome flying! But... everything ends sooner or later......
I just took her off, made a couple of flat spins and climbed to start another one. Entered into the rotation and.....control completely lost. The plane was doing flat spin rotation without control until hit the ground.[&o]
The engine (Saito 100), servos and reciever seem to be ok.
I decided to get either the same 60 size ucando or get 46. Still cannot decide which one...
So the question to those of ucando46 owners who put saito 100 on their plane: Is the throttle resolution acceptable in ucd46-saito100 combo, especially near idle position?
I'm asking because the main things I plan to further work on are upright harrier and rolling harrier. According to my experience on ucd60 - the throttle control should be very precise in these maneuvres... My mistake still the same: when doing rolling harrier - a after 5-6 rolls, I either apply to much throttle or vice versa and the plane quits rolling harrier mode and starts doing something similar which is not rolling harrier. And that happens with saito100-ucd60!. I'm afraid with ucd46-saito100 it would be much more difficult to learn rolling and simple harries due to lack of throttle resolution near idle. What could you say about it?
Thx

Question along the same line about KE. Do you have to have a mix set up for Knife Edges? It it a c.g. balance or thrust problem?

G,
I still don't get it. Sorry for being a knucklehead.....I think I need to lay off sniffing CA....or maybe more will bring me full circle

Mac, i use the rud to ele mix on a switch and also mixed in some rud to ail to help with wing vert on the same switch. if it dives to the belly then add some up ele when rud is applied and same with the ele and it will help but not cure, depends on how fast the plane is going so it will vary so i mixed in just enough on both to handle the middle curve and stick the rest, hope this helps.
also i have a hover switch and mixed in a little aileron to rud so the torque roll lightens up a bit, but you may like rolling

Hi All... Well I re-maidianed my "Do".... It was ok I guess... Got in about
6 flts... Man the 100 pushes some air on the 46, It would hover at ease
at about 1/8 throttle or less.. It floated/landed about the same as with the
YS 63 I did not notice any difference... I could not invert flat spin worth a
darn it kept outside looping out... Even with low rates.. I also noticed I
needed a bit of push while inverted. Guess I'll play with the C.G.. But
once/if I get that worked out, I think a rising spin will be easy:-) One
thing is for sure with the S-100 and 16x4W... The Wing Sings...
Ohh, fuel consumption seemed to be about the same time wise... Most
the time the stick was near idle
... Ohh and I have the 10oz tk. now..
dougwill & The MacDaddy I use to use mixes for knife edges, I think I
had about 4-5% on the rudder(master) to elevator(slave)... And I think
the same % on the rudder(M) to aileron(S) But I have since stop using
the mix and just work the sticks...
crank Not much test flt. (6) on the "Do" with the S-100 16x4W APC, But
my low end responds was good as far as I could tell, but you do have to
get use to "Just" touching the stick...... Or it's too much...

I realized the things i was doing by accident, you call 3-d flying. Waterfall-whats, inverted spin things, snapper-rolls. My KE looks like boomarang.
Must be something defective with my UCD.
I'll learn these things someday. Gotta love those landings & take-offs. Wife wants her trainer back. Maybe Santa will bring her one. Yes i did get foamie info. Thanks a bunch. Mid-wing airplane should not pull out of a KE right?
Stupid machine! Doug[8D]

Got my UCD from Tower yesterday along with my servo extensions and high torque servo for the
rudder. Those control surfaces are HUGE...really HUGE!! Not much of a vert stab but man does the
rudder made up for that.
I'm excited and will start building tommorow.

Happy 14th Birthday.
I feel really old. I have socks 14 yrs. old.
Don't worry about tailwheel. A guy i fly with, lost his 2 weeks ago and uses rudder. He really isn't on the ground much if you know what I mean. where do you fly at?

Just my 2 cents;
As someone mentioned, there are a lot of opinions, here is my set up, it works extremely well, remember flyin' is supposed to be fun, I hate to waste time at the field fussing over stuff, flyin time is to precocious!
1. Saito 82 is the way to go, if you don't have the coin for it, save and get it later you'll understand why. I have three, 72 82 and 100, I just purchased a YS 140 Sport for my Funtana 90, so I'll get an opinion on that too! BTW, do the research, you will find that OS 4 strokes are overweigh, over priced and are low Hp. They need to get back in the game. They had a 70 "Ultimate", so many problems the stopped making it. That is a 2" TruTurn Wide Blade Spinner up front with a 14x4W blade.

http://www2.towerhobbies.com/cgi-bin...?&I=LXGAE5&P=M
2. IF your a Futaba user, S9001 coreless BB servos are great for this plane, $30 @ or 3 for $87. No need for digi's, metal gear, whatever. I just bough some Hitec servos for the F90, yet another pending opinion, but I liked the acc. pack they had vs Futaba's, they give you stickers too!
http://www2.towerhobbies.com/cgi-bin...296&P=ML#mults
3. Great planes fuel valve and "Handy Mounts" - makes fueling easy, sand the firewall and mount with EPOXY, also seal the mount w/ thin ca.
http://www2.towerhobbies.com/cgi-bin...?&I=LXME95&P=7
http://www2.towerhobbies.com/cgi-bin...?&I=LXK135&P=M
4. Remote Glow ignitor - Saitos must have some kind of funny recess in the plug area, I cant seem to remember what I used......ugggg I will let you know.
5. Upgrade the clevises, I think I used Dubro slide locks and "Z" bends at the servos. A nice pair of Z bend pliers is about $12, I have the Hangar 9 brand.
http://www2.towerhobbies.com/cgi-bin...?&I=LXWH33&P=7
6. Hummm..... let me think.
7. Upgrade the tailwheel with the small Sullivan job, $7 or if you use the supplied GP type, run a couple of screws thru the plastic tab in the fuse, remove them and harden w/ CA, put screws back in.
http://www2.towerhobbies.com/cgi-bin...?&I=LXFV46&P=7
8. Custom tail braces - I used the technique and parts list from my Sig Somethin' Extra, see the photos. Here is some of the stuff you will need, looks like a lot but you might have it laying around already, use thin ca for thread lock, it doesn't need to be so tight you pull the surfaces out of wack, just enough so the loads can be transferred during hi G maneuvers to the entire airframe.

Here is another option, I always look at it in the LHS, but always end up building my own; http://www2.towerhobbies.com/cgi-bin...?&I=LXFV30&P=7
See my pics, if you are confused as to the assembly, l could explain it better or just scan in the Sig manual for you, no biggie.
9. Oh yea, I wish I had done this, Seal the gap in the ailerons and elevators w/ clear monokote. Instructions are in the attached Hangar 9 assembly manual from the ultra stick, page 9.
10. Best for last, landing gear upgrade, this is EASY, CHEAP and will AVOID a repair. Use the Dave Brown long reach CA applicators to get thin CA inside where the LG block is, you will NOT be able to see what you are doing, but it's worked for me. Get a lenght of 4-40 rod (smooth), and find a drill bit (I used a tap bit, not sure of the size) and test to find a good fit. Then take the drill bit in a dremel and drill from the inside of the plane, where the front of the wing mounts to the fuse, you will see where GP put some bamboo looking pins in, do it at the same height. DRY fit the rod in and mark correct length, cut 2. Tap the rod in and thin CA from both sides. The goal here is to get the rod near the top of the landing gear plate inside the fuse, where you cant see! You might be able to feel it if you can get your hand in there, or you can look w/ a flashlight from the hole in the firewall and you might kinda see it.

MACDADDY - Thanks for the info, and the time you spent putting that response together. I'm sure everyone here can use some of the idea's that you described.
DOUGWILL - Glad to hear that your wife is getting interested, I guess she decided that its safter to fly than watching after I almost hit her with my foamy !!!!
I decided to build a new UCD after putting my last one in. It's about done, just a few things left to do....... Heres a few pics....

MacDaddy, Hey! that's an awesome write up. I think it's the best I've ever seen. Lot's of great info and links there.
I haven't been able to fly here lately since the monsoons have set in........ [>:] I'm praying for another drought.... [8D]
Hey Barry. I haven't see you on here lately. Are you still around the thread?

What happened to the last one? Is this number 1 or 2? You should have seen me last night. Left my ground stake at home. No big deal right. Saito 80 starts easily at an idle. Then the fun begins. Set my radio down to take glow starter off and bumped throttle to high. Plane chased me in a half circle.
Imagine this coming at you. No harm done, only my pride. Flew 2 pretty good flights. Still haven't got a good knife edge. I should be able to do these. Someday.[

Ditto on the pants on. Gotta be careful.[:-] Great write-up on UCD construction. Have you had any problems with overheating? I notice some have been really opening up cowls. My 30% Heli fuel should be in this weekend. Hope you & Barry are right. MY Saito 80 needs just a little more for good vertical. Weight with it (heavier than 82) and 1100 batt. pack just not quite there. Next one will be lighter if necessary.
