That's amazing Jack. Glad you got her down more or less safe. Good piloting.

Thanks

I call them doohickies too. Must be a west coast thing. My wife doesn't like it when I doohickies though. [X(]

RE: U-Can-Do 3d 46?
 

I have a question I was hoping someone here could help me out with. I am putting a ys 63S on my UCD and it is the first YS in my hanger. I am using a GP quickfiller mounted on the cowl and I was wondering if I needed to remove the vent line from the check valve in order to fill my tank. If so, that is going to create a problem due to having it hidden behind the cowl on my bird. I was hoping someone here might be able to shed some light on this subject for me and what solutions work best.

Thanks in advance for your responses!

RE: U-Can-Do 3d 46?
 

ItsShowtime... Yeah you will need to get to the vent line to depressure the tank
before pulling the fueler:((.. You can just use a "T" between the tank and check
valve and just let it hang between the engine and firewall... I used J'tec plug
type fillers on the top of the cowlon both the fuel lines.... Yet I still had a few
spraying of fuel mishaps:((....
I know they moved the regulator to get more cooling on the YS 63S... But make
sure you make big intake and exhaust cutouts in the cowl for the needed cooling
on the YS..... And Remember.... Vent first..... Then fuel:))))))))))

RE: U-Can-Do 3d 46?
 

yep, Ron is right, you need to put a "T" in the vent line between the check valve and tank, then run the line where you can get to it easy, maybe put a fuel dot on the end of it ande make it look cool[8D]
just unplug the dot when your ready to fuel and it will vent the tank;)

here is a link to the dots i use!!

What size tank are you using with the 125? Run times? I'm using a UCD60 stock tank in my Velox. It's 15oz I think. I'm hoping for 13 minute flights.

I'm almost done with the Velox. All I got to do is mount the battery and tie the raido gear down. Nice looking airplane. I've also got to break the engine in. I'm gonna do that on Monday, just run it in the plane.

Let me know.

Thanks
Barry

RE: U-Can-Do 3d 46?
 

Barry, im using the stock ucd 60 tank with the 125 and it gives me 12 min easy flying time, i have it all leaned down now so if your breaking it in on the plane a little rich just keep her down to 7-8 min till you see what it is using;)

RE: U-Can-Do 3d 46?
 

Well it looks like I can save on fuel cost today. It's so stinkin' windy here today that I could just throw the plane up in the air without even starting the engine..........[>:] And yesterday was gorgious out. I had to do some things with the wife so I didn't get a chance to fly..........Arrrgggghhhhh! [>:]

RE: U-Can-Do 3d 46?
 

that gives me an idea!![sm=idea.gif]
tie a string onto the prop nut Rob and with an assistant throw the plane in the air and fly it like a kite with your controller[X(]wow i just invented the rc kite:D

RE: U-Can-Do 3d 46?
 

:)gjeffers...
Thanks for the info. Sounds like the Saito will use fuel about like the YS. I've heard horror stories of the 180 drinking fuel like water. But sometimes I wonder if those people get the engine leaned fully in the low end. That's where I do most of my flying. Mid range with the occasional full throttle burst. My Saitos have been pretty good on fuel I think mostly because I lean the low jet wayyyyyyy down. Anyways, I'll go for 8 minutes to start. My luck the plane won't last that long anyways.

RC kite. What a great idea. I'm gonna suggest that here in Idaho. We have plenty of wind. My luck it'll be accepted the same way my suggestion for "Hat Bolts" was. NOT!

Have a great day guys.
Thanks
Barry

RE: U-Can-Do 3d 46?
 

it is the low speed idle screw that sc--ws ya as far as fuel consumption Barry, i dont squeez my line(although it is close) but i do my carb like i do my rockchesters and other old carbs, after the engine is brok in i just take the idle screw down till it dies(or almost, whichever comes first) and then bring the screw back out just a little till it starts to idle a little rough and then go in a hair and im there, idleing smoooooth;)
then set the top end and your good to go,jmo[8D]

RE: U-Can-Do 3d 46?
 

:)gjeffers...
That's how I adjust mine too. They'll run pretty good even when rich on the bottom. But the mileage goes south. Also, the transition is better when leaner even though you may not notice because it runs so good when overly rich.

Thanks
Barry

RE: U-Can-Do 3d 46?
 

Hey! That is an idea! [8D] Imagine the flights I can get at the ocean. [X(]
Well the monster winds did die down and I got to go to the field to get some time in. I spent most of my time helping a couple of guys so I didn't fly as much as usual. One even asked me to fly his plane and check it out. Yikes! The president of the club and another instructor have been asking me to be an instructor so maybe that's the direction I'm heading.

RE: U-Can-Do 3d 46?
 

i could be and instructor too[X(] but i have no instructees around[&o]

so instead im rebuilding and recovering a h9 arrow for my granddaughter, its gonna be pink on top with some flowers all over it, and white on bottom with powder blue stripes:) good stuff!!!

RE: U-Can-Do 3d 46?
 

WHAT! That sounds like one of my planes........[X(] Hey, you stole my design ideas..........[:o]

RE: U-Can-Do 3d 46?
 

Well, I finally madiened today!

It was a long journey for me and the plane... I went through many issues (mostly engine) that kept me from getting airborne. With the help of the RCU Saito threads I finally got going. WOW! What a plane! I had a blast... weather was picture perfect today - temps. in the mid 70's, winds around 8-10 MPH. After a couple rough moments (again) with the Saito .91 things finally got purring the way they should.

First flight was totally uneventful. 1 click of trim on both the elevator and ailerons and things were straight and level. Low rates are very predictable... high rates are a bit much, especially on the rolls and snaps, but I think that's more me than anything else. For now, I've dialed the throws on high down a bit, maybe 15% on each surface.

The power on the .91 is just obscene! Vertical is like a rocket with a 14x7 APC. I typically spend most of my time around 1/4 to 1/3 throttle. Hovers (while sloppy - again my fault) were well below half throttle. The Saito already feels like it's breaking in well with just a half gallon of fuel. I can already easily idle around 2100 / 2200 rpm and let it dip below 2000, but it starts getting rough there. I needed to get a 1.8 size starter and everything fell into place after that.

Now for the bad news...

1. Carrying the plane to the flight line (how I did it with my trainer) I managed to break one of the spars running down the turtle neck when a small gust of wind got under the right side wing. The spar was resting against the bottom of my right arm and just gave way really quickly. Didnt seem like much force to break it at all, but things happen. The Monokote had a 1/4" tear in it as well, but the damage wasn't enough to make me quit for the day - it happened at the begining of my 2nd flight and didn't seem critical or structural.

2. An accidental harrier landing on my 5th flight (it seemed to float forever and then just DROP) from about 4' put a big enough nick in the APC to warrant me trashing it, but everything else seems fine aside from some scratched monokote on the wing tip. Gear was OK - nothing rattling or loose.


Man, I can't believe how much work I put into this ARF getting it airborne! I'm sure the experienced I've gained will make others easier. In one day I managed to cause more damage than I did in four months with my trainer... LOL. I better pickup a backup U-Can-Do shortly. :) Positive notes are that in 5 flights I've already done things my trainer couldn't even think of. And I've learned some good repair skills!

Pictures show the bracing / repair to the spar. The new "trim" I've added to wing is to compensate for my harrier landing and the subsequent abrasions.

RE: U-Can-Do 3d 46?
 

Well done and congratulations, Wayne! With that .91 just remember she's waaaay overpowered. After a couple months with my 46 (OS .61FX, also overpowered), I decided to bring it back across the field at full power, into the wind, gusting to 20 or more. When she got close enough, I saw the elevator, shaking like mad, then went askew before I could reduce power. I landed fine, lucky.

The starboard elevator half threw the nylon keeper on the servo arm, it vibrated so much. And the horiz stabilizer came loose, with a piece of balsa on TOP of the stab, port side, missing. Easy fix, all of it. But the caution remains. If you overpower, keep her slow.

Sl1200MK2...

Congratulations on your first few flights. Sorry about your minor mishaps. They are built light, so you must handle them carefully. However, I must say I think they are as tough as any other seriously 3D ARF. You just got to be careful in the way you handle them. When you get used to it, it just comes normal. No problems.

I think you need to change props to a APC 15x4W. That'll keep the speed down naturally and it will make 3D easier, especially hover and that infamous "inverted flat spin landing". You'll fly all around better with that prop.

Have a great day.

Thanks
Barry

RE: U-Can-Do 3d 46?
 

congrats Wayne, these planes are a little fragile on the back side but they need to be,from looking at your pics id upgrade to 4-40 rod asap on all control rods, i just dont know why they supply 2-56 with these planes, just not strong enough:eek:this is a good plane and lots of fun when you just come off your trainer;)

good job!!!

RE: U-Can-Do 3d 46?
 

sl1200mk2
Congrads on maiden flights.:D Listen to these guys about modifications. 15 X 4p prop especially. Also let me throw my two cents worth in. Seal those gaps in control surfaces with clear Ultracote. Might keep them from fluttering or save a control surface from coming off. Makes them more effective if air can't get through also. Really jealous of those that are flying now.:( Our weather forcast for later this week is 50 to 60. Need to upgrade my control rods to 4-40 before then.

RE: U-Can-Do 3d 46?
 

Con-Grads on the maiden sl1200mk2..... As always, great advise above!!

Well I'm starting my build of UCD#2... Still wondering what will go in the front...
82 or 100????????????? But if I know me... It'll still be a bit:(.... And "NO"... still not a
thing from that Great Post Office Claim.... WoW..........

My "SPAD" flew pretty good. Not as fast as I thought it was going to be with my weight
savings from the other spads for the game:(... alone with afew other changes. They
all told me so:(... I do need to do some work on my weak wire gear..... I missed the
pylon race:(... My ail. mini servo stripped a gear on my third flt. before the race:(((
squirrelly little thing....

RE: U-Can-Do 3d 46?
 

:)radieron...
I'd go with either the 82 or the 100 on this plane.

Thanks
Barry

RE: U-Can-Do 3d 46?
 

:)Oh yeah...

It looks like we'll get some flying weather this year. According to the weather forecast.

Thanks
Barry

RE: U-Can-Do 3d 46?
 

Wayne, Great job on getting your U C D in the air. The repairs look good too and it's good experience. As Barry said I would try the 15w x 4 prop too.
Hey Barry, I got the Higley hub that you mentioned to try out. It looks great.....
