Well Meeko???? How it go? Inquiring minds want to know...

hi mordib and all friends!!!

3 flights in 20mph side wind, and two cuts engine,
with my new saito 100 )-:

thats was to hard!!!!

the screws of the canopy flies away cos' the vibration
of my saito, any suggestions what to do with the canopy?

in the air the plane is very very stable, and thats was realy fun.

i'm think that i must to take the CG reverse, what u guys think?

one CA hing is aileron is "hang-up"

i will fix all the problems and hope the next saturday will be more happy and fun.

The Saito can be a little persnickity until it breaks in some... make sure you are running rich and not lean... that should help prevent the flame-outs...

The canopy? Well I just put alot of small screws in mine... about 22 button head, spaced 2" apart...


Don't change the CG just yet... It's better that you get the feel of the plane first with a few flights AND have the other kinks worked out... It IS satble and can be moved back a good bit, but do so in 1/4" increments until you feel it's where you want it...

Glad to see you got thru the first flights... You're gonna love it when you get more stick time on it and that Saito comes into it's own...

mordib, yap u right i realy hope that things go better...
i promise that u will know that (-:

if u have more tips...i'm here to listen

Was in the hobby shop yesterday and he had a book showing new items coming soon, and they're coming out with a 46 size UCD. That should be a good plane for someone already set up with smaller equipment that may be intimidated by a plane as big as the UCD 60.

See if I can post some pix of my UCD cowling. I thought I'd have some with it.

was hovering mine today at about 5 feet when the engine died and it did a nice tailslide. u'd be suprised at how tough the fuse is. the rudder is totaled but the fuse took no damage. it did fall to its back and busted canopy tho

Here's another one.

That is the most AWESOME cowl job I have ever seen!!!!!

Cool, a menacing UCD!

yeah that copwl is nice, where'd u get the grafix?

A few days ago I was hovering my UCD a couple feet above the ground when the ST 90 sagged. As the UCD fell, the nose pitched slightly down, the tail hit the ground first, and then the plane fell forward and hit the ground fairly flat. The pancake landing broke the nylon bolts holding the landing gear, with virtually no other damage....not even a broken prop.

In fact, this exact same scenerio happened twice within about 15 minutes, and both times all it did was break the nylon bolts holding the landing gear.

Wow, am I glad that the UCD was less than 3 feet from the ground when the engine sagged! Otherwise, this would have been an entirely different story! (In fact, the reason it has nylon bolts is due to a previous engine flameout at a higher altitude. That crash knocked the firewall loose, and broke the landing gear mounting structure.)

Here's an action photo of the UCD that my brother-in-law shot. At first glance, it looks like a UCD taxiing on the runway with the engine idling. But in reality, the photo shows the UCD at the exact moment of impact during one of the pancake "landings". Notice the landing gear has already broken loose, but the prop hasn't yet touched the ground and is still spinning. One wheel is visible under the fuselage near the trailing edge, and the other wheel is visible under the right horizontal stab.

it accually suprised me at the minimal damage from falling from that far. just time to rebuild a rudder
i am thinking edge 540 sized rudder maybe

UCD 3D cowl
Actually the face on the cowl was airbrushed on by one of our club members that's it that sort of thing. He sprays RC car bodies, and the like, and when I told him of my idea, he was excited to do it. It only took him two day to have it finished. He clear coated it with a clear enamel. I thought it turned out quite nice and interesting!

Awesome looking cowl. I was just talking to my brother-in-law last week and ask him to do something simliar to that. He's a very artistic guy.

I hope your not flying with the spinner like that. Hopefully you have it like that just to take the picture. If not I think you either need a new spinner, or you better tighten that one up

get a difernt color spiner cuz that one dosent look good with the awsome cowl

By this time there must be several of you that have now settled on your ideal set-up for mixing and coupling channels. What have you mixed/coupled for various flight situations? I'm using a Futaba 9C radio and my UCD is balance at 6.25 inches. My plane tucks badly on heavy rudder and tries to snap on heavy elevator.

Where is your C.G. ? It might be set too far back or your throws are too large. I indeed had to program a mix to fly knife-edge. Never had the problem of snapping when applying full elevator though (at least on the UCD... I had this snapping occurring on my Giles due to the CG being a little too far back... varies plane to plane).

UCD Cowl
The spinner was on for the picture, not for flight. This bird will see it's first flight this next week, if the weather turns nice again. It will be flown with no cowl until it gets trimmed out and flown a few times. I have a solid metal chrome spinner that I'll use on it.

Has anyone flown this plane with a OS61 FX and if so what prop is working ?

Bob

I know the UCD is technically a 60-90 size aircraft. But to be honest I wouldn't even consider putting a 61 in it. most UCD are ending up 7-8 lbs. A 61 will not be able to take advantage of what the UCD has to offer.

Others may be able to prove me wrong and give you better info.

These are the settings on my JR8310:
Exp: Aileron 70%, elevator 70%, rudder 50%
Elevator>Flap mix =125%, still experimenting for Elevator/Harrier
Rudder>Aileron +10% for right rudder, and +8% for left rudder
Rudder>elevator +8% for right rudder, and -10% for left rudder
SPOI>SPOI -100%, -100%: this is to get rid of any switches or pots on this channel, since it is my other elevator( reversed direction) channel
Elev>SPOI -89%, -104%. This should be -100%, -100%, but it is a mode 2 transmitter and I fly mode 1. It used to be the throttle channel!?!
These are the settings at the moment, but they may change as I trim the plane in some more. Hope this helped

My CG is 6.25 inches behind the wing leading edge. I must admit I had extreme throws on both the elevators and the rudder. I used the the outer most holes on 1.5 inch servo horns. I'm sure I had too much throw and have since taken some out. The plane has calmed down somewhat but still tucks pretty good when I try to do tight knife edge loops.

Thanks for your reply. Here's how my Futaba 9C is set up:

* No exponential settings used - I never liked exponential, however, I use triple rate settings off of triple rate switch "C" which is set up as follows:
* High - Ail 120%, Elev 115%, Rudder 140% (wild stuff happens at this setting)
* Normal - Ail 80%, Elev 75%, Rudder 100%
* Low - Ail 50%, Elev 60%, Rudder 80%

* Elev > Flap Mix set at positive 100% on a separate triple rate switch "G" when in the full down position. This causes the ailerons to go down like flaps when the elevator is up and to go up when the elevator is down. Makes for tight loops.

* Elev > Flap Mix set at minus 100% also on triple rate switch "G" when in the in the full up position. This causes the ailerons to go up when elevator is up and down when the elevator is down. Used for harriers, etc.

* When Switch "G" is in the middle/neutral position no mixing or coupling takes place between the elevator and ailerons.

* Variable Slide Switch "D" is set up to either raise or lower the ailerons manually if desired. No coupling with anything else.

* Switch "F" is used as a throttle kill switch. Since this transmitter has electronic trims as apposed to a slide I found it more convenient to be able to close the carburetor from a switch instead.

* Switch "H" is used to activate rudder to elevator and rudder to aileron mixing for knife edge maneuvers. Both elevators and ailerons are set to 10% as a slave to the rudder. These numbers still aren't quite right and I'm still adjusting them.

* I used channel "5" for my second elevator servo and set it as a permanent slave to the elevator channel #2 with links and trims set for "on." This allows for independent elevator neutral and endpoint adjustments for perfect alignment.

We fly off a grass runway,I haven't made a bad landing yet, but after just a couple of hours flying both spats have fracture marks either side of the alluminium undercarriage. I have repaired them on the inside with fiberglass tape and resin. I'm assuming that the cause is vibration
Anyboby else experienced similar stress cracks
