Sounds good Gary... Now I just have to get to doing it... My gaskets should be here in a
day or so... But I still have two to put together and two to repair..... :-(.... I have to get
on the stick here... Glad both of your's are purring....

Well had a ball in my first combat)) It's a blast!! We had 9 up today, and when all were
up no midair's... Then there were 3 left, Two were heading towards each other, and I was
coming up from the deck).. about 10' or so they have a midair and I just fly by... Wow..
Man that was fun!!!!! They said I was the only one to get a streamer)))... Man it looked
like a swarm of bee's.....I looked away once and took a bit to find my plane... Last time I
do that.... What a blast!!

Vs reading all these threads a Saito 82. will do great in the UCD .46 ?

Yes! That's what I have in mine and it works great. The 46 is more like a 60 size plane and the 60 is more like a 90........ or something like that.

Rob - Thanks for th response. I will pickup a saito 82 then.

liv, a note of caution from a guy who didn't listen. The 82a is definitely overpowering the .46. That's okay. We all do it. I have an OS .61 on my UCD46 and the Saito 82 is on my Twist. If you ever think to make a high-speed pass for fun, as I did, don't. You'll get some strange results from the bird. I lost my starboard elevator in mid air, the hinges held the elevator, but the connecting rod came loose from the servo. I SAW it go. I landed okay because the ailerons overpowered the tail problems, but the nylon keeper on the wire connecting rod flew off because of the vibrations in the elevator. A chunk of balsa, on the PORT side, got broken where the elevator goes through the fuse, too. It's an easy fix, lucky. But there are REASONS why they caution overpowering the UCD.

Good luck,

Jack

Jack -

I appreciate the word of caution. If go with the Saito 82 I guess I should beef up the control surfaces. Does the OS .61 give you enough power for all 3d maneuveurs.

Thanks for your suggestions

Mark

oh now dont scare him Jack, i flew my 46 with saito 100 and never had such a problem, just use dubro pinned hinges(or equal) and carbon fiber push rods, i flew the heck out of this plane and nothing bad happened till the main left wing blew off(after about 300 flights)

just my 3 cents worth, but Jack is right about flying fast, dont do it

LOL - Thanks Guys !! I will pickup the saito .82.

Yes, Gary, you can go full throttle doing inverted spins, rising. You can go full throttle out of a hover. But if you go down wind and come BACK, into the wind, across the field full throttle, my mistake, you may discover why all the cautions about over-powering.

It's only when the wind goes high speed over those control surfaces that you have a problem.

And listen to Gary about the carbon fiber connecting rods, almost a must on the UCDs, 46 & 60, long connecting runs. I've gone to the ball joints on the servos, carbon fiber for the rods, and Dubro SAFETY Kwik-links for the horn. Those are one-time buys, I reckon. That system will outlast the bird in almost any kind of crash, so they can be reused, time and again on new or rebuilt UCDs.

Incidentally, I bought the carbon fiber rod into which a 4-40 threaded rod fits perfectly without forcing, about the same as the titanium rods, but waaaaay cheaper. I tested the threaded rod, cleaned twice with rubbing alcohol and glued with JB Weld into the carbon fiber rods. I waited 24 hours then hung one of my 25 lb sacks of lead shot on the rod and left it there, twisting. After an hour, I picked up the bag and DROPPED it about 8 inches. The 4-40 rod on one end, bent to hold the rope, straightened out, but the connections didn't give. I rebent the rod and dropped the weight AGAIN. I broke the rope, not that big, twisted hemp.

In other words, save the money for the titanium connectors (at 2 bucks a pop). You can SAFELY use JB Weld, let it cure 24 hours, and threaded 4-40 rod.

Good, safe flying, all,

Jack

I have used the 4-40 rod ends and carbon fiber rods with great success so far. I doubt that they could ever pull apart. I think that something else would pull apart or break long before the rods will ever come apart. I would prefer to use the titanium ends but don't want spend the extra $ on them. I used to work as a materials tester at Boeing (still work at the big B but work in a different department) and would tensile test lots of different types of stuff. I remember when we would get in some of those electrical zip ties in to test and even the smaller type ones that are about 3/16" wide and about 8" long would tensile test at over 50 pounds. Anyway, the metal rods that come with the U Can Do bend too easily and are best replaced with a carbon set up. IMO

Another thing that's really great about the carbon fiber push rods, (just figured this out last night) they can be used as a high tech straw. Soild as can be. Doesn't bend. Smooth, and very stiff.

Another use...Use them to bull servo wires through the wings and deep from the fuse. Also, great way to line up the pull/pull wires. It gives you the place to cut the fuse where the wires come out.

Great things...carbon fiber tubes.

Thanks
Barry

ust wondering...I know I have been through two or three UCD's, Just love them!!!

Most due to dumb thumbs...mind lapses...or just messing up!!!

What do you guy's do with the left over pieces other than trash them?

I posted this on another thread, in 3D, but did not get much response. I enjoy trying to put the peices back together again, and/or modifying them...I would like to hear what you guy's might have done!

Thanks,

Jimmy

Can anyone give me some advice? I just mounted my saito .91 to my ucd .46. I know this is somewhat overkill but I'd like to try it for kicks. What prop size should work best? Thanks!

Hi all:-),

Barry I never thought about your C.F. ideas.... Love it:-)

Antennaman... I never tried a S-91.. But I would think 14/15X4W??? I used a
16X4W on the S100 on my 46 "Do" before it's demise, due to a broken connection
at the battery:-(

Well, "Do" # 2 should be done by next week, Not B 4 the fun fly for the leaving snow
bird members:-( Anyway I was trimming to fit the 10oz tank in, and started installing
the engine mount(stock) for the S82.. And saw that I could raise the Saito close to 1/2"
by installing the engine mount upright and installing the Saito on top of the mount
inverted.... Need to make some small adjustments, which a club builder said that it was
fine doing it that way...... Has anyone done this?? Thought's??

B Good people....

antennaman, my son uses a 15x4 on his 91 and it works great.

Ron, sounds interesting, try it and let us know.

ok guys, im about to order my next plane, a goldberg pitts 12 monster, gonna put a saito 150 on it, man this is gonna be great. this is the best part of this hobby, NEW PLANES

Raideron, I was also worried about the fuel tank/carb elevation and mounted the engine, inverted, on the top of the mount. I gained about 1/2 inch toward dead center, tank/carb. I haven't been able to try it yet, darn.

Jack

gjeffers...

That Goldberg Pitts is a great looking plane. I've been thinking about a bipe myself. Only I've been thinking about the Great Planes P6-E Curtis. I just love the looks of that plane. I'm not sure you'd be able to do that great of aerobatics with it, but it's neat looking and I'm sure it'd be fun to fly.

Yours will do great aerobatics. That 150 ought to make it fly wonderful. Good choice.

I got two flights in last Saturday before the snow got me. Might get a few more in this week end. Should be fun.

Have a great one guys.

Thanks
Barry
PS: My Mom passed away yesterday. I'm a bit distracted as we plan her funeral.

I've been flying my UCD with a Saito 65 inverted and have had no problems with the engine inverted but I've been thinking of switching to the 82 to get a little more punch out of the plane. It sounds like some are having flooding problems with the 82 inverted on this plane.
Has anyone that's flying with the 82 on their UCD had problems with the the motor inverted and stock fuel tank location on this plane?
If you raise the engine the 1/2 inch you guys are talking about, how does that effect the mounting of the cowl?

Barry Cazier.. Very sorry about your Mother.. Our condolence and prayers are
with you!!

rtn9105..... IMO if you had no problems with the S 65, the 82 should do the same
as long as the carb. is at the same height...
Most don't have many problems. When I had the S100 in the 46, it had little problems,
but I did lower the tank somewhat.. Now when putting together "Do" # 2, and just
getting the S 82, I thought of lowering the tank, Then I thought about the upright
stock mount( well I installed the mount that way by mistake, then saw the height
change) and the S 82 sitting on the top of the mount inverted.. I did have to shave
a small bit of the mount about 1/16 to get the carb to fit between the mounting lugs,
but i wil have a better tank/carb relation than I did with the S 100, and it should tune
better, with less chance of flooding, and I can't see that hurting the mount.
On the cowl, I'm not going to install the cowl mounting blocks, instead I'll just screw
into fuse/firewall.. With or with out the cowl mounts, the cowl fits as it should.

Gary... I used your landing gear "Beef-up" block tip:-)..... Was easy and Works great!!

ANTENNAMAN - I have an OS 91 and a 15X4W APC, on my UCD. It's a ball try a 15X4 and I think you'll like it.

In my .46 "Do" I have the tank higher up into the canopy and further back to enable a larger tank for the Sa 100 inverted,no problems other than some siphoning fuel into the carb IF I leave the carb open after fuel up. I always turn on radio/rcv to make sure throttle cut switch is on to stop/slow the flow before I fuel up,then I make sure I start engine immediately after turning on to fly. I do not need to prime the engine,in fact if I do it will flood & lock it up.

Barry my friend. I'm so sorry to hear of your mothers passing. It must be a difficult time for you. You are in my prayers.

Rtn9105, I have the Saito 82 on my 46 and installed the tank in the stock configuration and haven't had any problems with flooding at all. Most of what I have heard it is the 60 size that has the flooding problems. I used a Dubro fuel filling connection (don't remember what it's called) and made a loop with the fuel line and it doesn't leak. I have pictures of the set up at home and can post some when I get home. I'm still in Mexico. [8D] I'll be home tonight.

Thanks guys! I went to my lhs yesterday - The only prop they had that fit the s-91's recommendations was a 14"x6 Zinger. Strange. Apparently my lhs is going all electric now? Hopefully, I'll see how she works today.

Rick.
