thanks Jack, all good advice, i do have a problem with working on my planes in the front living room, she sees everything[:@]
maybe i can put up a couple of locked doors and tell her its a weight room yea thats the ticket, it might work
but Ron can tell ya just how important that air comditioning vent is out here in the beautiful desert

ps. there are two more planes where the treadmill is[8D] she really isnt that bad, just gave me 1400 bucks for a new baby

Gary, at $1400 ... well, that's not a "sweetie," that's a "Sugar Momma!" And for THAT kind of money I wouldn't mind being a kept man--and would admit it to any flyer who asked.

Well done, bro!

Jack

P.S. And what did you do with the Saito 125? It ain't on the Can Do 60, hangin' on the wall. I thought that's why you bought that Saito.

its an old pic Jack, it is on the 60

WoW Gary! That's a nice bonus or gift or something. Cool. [8D] Maybe I should have my wife talk to your wife. [X(]
Did you need to use a pump with your 125?

no pump Rob, carb is pretty close to centerline, gottta go fix a leak under the sink now
but maybe ill get enough atta boys to get a 46

Well, I got to break in and fly the new UCD 46 today. The wind was pretty bad most of the afternoon, it was between 20 and 30 mpg with a few showers. I finally gave in and decided to do a break in run on the Saito 82. It was my first 4 stoke. I ran a tank through it at about 4400 RPM and then leaned the high end to get 9500 on a 14x4 APC prop. After adjusting the low end just a little to get a semi decent idle and transition, I took it up. It would cruise around at 1/4 throttle just fine. The low end was doggy, but when I got it to 1/2 throttle and it cleared its throat, it would hum. I flew two tanks after the break in tank, and the last one seemed like the motor was getting closer to stretching its legs. I could not believe it when I did a climbing inverted flat spin. It was an acident, I was up at about 3 mistakes high starting to do an upright flat spin when I flipped it inverted and watched it spin down that way instead. I started to feed in a little throttle to recover and it just started gaining altitude. I could not do that with my other UCD with an OS 46. The only thing I did not care for, and I dont remember my other plane doing, when I give it very much rudder the wings pitch the oposite way pretty bad. I cant get over the sound of the Saito. It was twice as loud as my 46, and the sound residence throught the plane was awsome. I just need to make a few minor adjustments before the next trip out and then I will run about 10 more tanks through and lean it out and get the cowl on.

Congrats on the new UCD with 82. Great combo. I love mine. Just a super flying airplane and a lot of fun to boot. Great job. Once you go to 4 strokes it's hard to look at anything else. At least for me.

Thanks
Barry

Good morning!...

Got the Big Do done last night! All up weight ready to fly with no fuel was 11lbs 15ozs. Gotta love it. I didn't do anything real special to keep the weight down. Just didn't use the wheel pants and did use common sense. I didn't reinforce with a bunch of glue but I did a little around the landing gear.

It's a very pretty bird, at least in my eyes. I can wait to do the maiden. Probably Wednesday. I think I can sneak out for a couple of hours then.

The 12Z is working perfectly and this will be it's maiden also. I'm gonna transfer all my planes to this radio and then sell the CAP 9C. This radio is fun. And will be exceptional when I get the other planes tied to it. But you can't really (at least easily) use the 9C as a back up because the channels are different. You can program the 12Z to change the channels to the same as the 9C but you will lose some of the "real time" speed you gain with the 12Z. The 12Z groups the channels together. 1&2 are the ailerons, 3&4 are the elevators, 5 is rudder 6 is throttle and 7&8 are the flaps. Anyways, once I prove up on the radio I'll transfer the other planes to it and change the channels in the receiver to the above and then it will make the 9C obsolete for me.

Anyways, I'm very pleased with the weight on the Giant. 12lbs should be good for the OS160. I still have to run a tank of fuel through the engine for break in and I'll do that tonight. I'll also take some pictures of the huge beast.

CG was the easiest to balance of any plane I've built. I installed everything where it looked good, except the battery, and then did the balance. The battery ended up being right on the wing tube. Basically right on the CG. That's a great place for the battery because there is practically no inertia created by the battery weight so it's a lot less likely to break loose in flight.

Plane and radio are ready. So am I. This week is gonna be fun.

Thanks
BArry

Have fun Barry.... Keep the wheels down..... Well unless your going to start right off in the
ol' inverted F. S. landing... SShhhhhheest Got a new gaint bird and a new hi tech radio... Should
make that invert landing a breeze!!!

Let us know how your "Great flight" went... Don't for get the pics...

what is great about this sport Barry is that we can all feel the same feeling that each one of us feel every time we maiden, so you know were with ya

sounds kinda korny huh[&:] but you guys know what im saying[8D]

Pictures as promised.
Thanks Barry

PS: Giant with 12Z

Another one.

And one more

WoW! That's nice Barry! [X(] Have fun with your maiden flight. [8D] Very cool plane!!

She's HUGE Barry!!!.... She looks great!!!..... R U sure she fits in the truck)
One thing's for sure, That engine will get loads of air... Great Job
Now the Flight report..... Hey, hold up on that inverted F.S. landing for now...

That's an unusual looking prop nut

Wow, what favorable wing loading! Isnt it 80 some inches? At 12lbs it should float like its lighter than air. OS 1.60 is a keeper,mine even ran with a cline with medium size tubing,had to put the cline on a Goldberg SU26(72" wing) because of sagging engine during rolls,snaps&anything other than straight&level flight. I think the 1.60 went lean when the clunk was in the air pocket(had 24 oz tank).
The Cline fixed that. You wouldnt think an engine that size would run rich enough when you look at how restrictive the cline is. Anyway,with all the surfaces you have to play with,should be a blast.

Mixmaster...

The wing loading works out to 15.683ozs/square ft. The only thing I have lighter than that is my UCD46 at 15.2, It should fly very light.

I'm a bit disappointed because I did the break in on the engine today. It ran perfectly and idled just great. It spun the 18x6 prop at 8550 RPM. All that sounds great but my thrust was only 13lbs 6ozs. It may get a bit better. I hope so. And I was the only one there so I wasn't able to "free" everything up on the straps etc. which sometimes helps. But to put that in prespective my mighty 110s make 13lbs 0ozs under similar conditions. And the engine is a pound less weight. That means the 110 would probably fly it better. 11lbs weight with 13lbs thrust vs. 12lbs weight with 13lbs 6ozs. But I'm probably doing something wrong. I'm hoping for at least 15lbs thrust out of the 160. It may do it when I can get a helper there to assist me. Also, I might change to a 17x8 prop. I've heard those give more thrust.

Anyways, regardless, it should fly very light. And fun. I might get to maiden it yet today. I hope so.

Raideron...

She won't fit in the truck until I put it cross angle. She's big. Air flow is important. Don't want to overheat.

That spinner is what came with the kit. A polished aluminum spinner. Quite nice actually.

I'm gonna try and avoid the inverted flat spin landing.

Thanks
Barry

Barry,
In the "Tachometer Readings" section, page 3, about half way down, there are 2 threads reporting rpm for OS 1.60 fx engines. It looks like some fliers got a tad more rpm with an 18x6 than you, but not a lot. An 18x6 at 8500 rpm at your altitude would produce about 13-14 lbs thrust according to data I have. My curves show 15 lbs thrust for an 18x6 at 8500 rpm at sea level. I am guessing a 10% to 20% reduction for the reduced density at your altitude. Maybe a prop with a little less pitch would let the OS rev up closer to its max power rpm and give some more thrust. 8500 sounds low for a 2stroke but I am not up on how those big ones are timed.

Jack Hyde...

Yeah, I've seen some of those posts. Some say they are getting as high as 19lbs maybe with a little different prop. But I never seem to get what others do. My elevation is the killer. It really hurts. Also, I must be patient as the engine is brand new.

I was thinking the same thing as you though. I'm going to try a 17x6 and a 17x8 (I have both those props) and see if I get better readings.

The OS160 is rated at 9000 RPM for it's max horsepower of 3.7. I want it to spin right there if I can get it to. The 17x8 has my eye.

It shoudl fly pretty good with the 18x6 for now. As soon as I get a little time and the nerves settle a bit I'll go for more thurst and a bit more 3D stuff.

Thanks
Barry

really nice BArry, i dont think the LG will come off as easy as the 60 or 46 with all those screws
gotta be a blast to fly(your probably out flying as i type)to hot here in the afternoons, im back on weekend mornings at sunup!!

Hey guys, guess what i just ordered, lets put it this way---- im a legal member of the ucd46 thread again
