I need to make an engine selection for a 'new' US 1000. I was thinking OS 1.08 or 1.60FX.
I'm a sport flyer who likes to do Big Loops.
Any thoughts?
Thanks,
Jim

The 1.60 is going to way too much motor for a US 1000. If you just want to sport fly then 1.08 would be a very nice motor for it. I'm getting ready to build a US 1000 and I have a YS 120 4-stroke for it.

This is a great plane, have fun with it.

I don't have any experience with this plane, but I was also considering the OS 1.60. It would be at the upper range of 2 cycles listed, but alot of people put ST 2500 and 3000's in them.

I have seen a pair of US1000's fly with ST 3000's and they were awesome, but had trouble landing because of too much 'idle thrust'. They had to run a smaller dia. prop than the engine liked and made up for it with more pitch. I'm sure this contributed to the problem.
Seems like the price of the 1.08 is awful close to the price of the 1.60.

Kelsey, you have a US1000 too?

I get the feeling the 1.08 is a higher rpm engine than the 1.60 and could run a smaller prop, but perhaps the 1.60 could run a 3 bladed prop?
That stock muffler on the 1.08 sure is HUGE!

Jim,

Yes, I do have an US 1000 kit. I thought so much of the 60's, I purchased a 1000 when I had the opportunity. I don't have immediate plans to build, but it will be waiting when I do.

I have been flying an Ultrasport 1000 now for a few years, and its an awesome flyer. I have a OS160Fx w/std muffler installed, running APC 16X10, the 160 is the perfect engine for this plane, I wouldnt use anything else. I also used a JTEC anti vibe mount because thats what the manual recommended at the time, not sure its necessary, but I did it anyway. I built mine with dual elevator servos, and tricycle landing gear. This planes will do huge loops, and is by far the best lander of all my planes, it will come in at a crawl, it will knife edge all day, and inverted flight is great.

I did bend new landing gear to make it sit up taller, and purchased a fultz front landing gear for it, the stock was too flimsy. I used a seperate servo for the front gear to take the load off the rudder servo.

You will love this plane, mine is on charge now for flying today!!!

I will snap some shots of it today at the field, and post them later today.

I have been flying the 1000 for quite a while with a YS 1.20 FZ. Plentyof power for this. Great smooth flying aircraft, lands a little hot but used to this on grass. See it in the photo gallery under my user name halflight.

Daz, that's quite an airplane! 1.60 no less! You have no trouble landing with it floating too much? What size tank does it require?
How is the CG with this engine?
Any other mods you didn't mention?

Also thanks to everyone else who posted. I now have plenty of engine choices.....

A7BLDR, the plane lands beautifully, no problems at all. Everything is installed in the wing saddle area, the battery(4.8 1400mah) in right inline with the wing saddle bolts for balancing. No other mods than what I mentioned above. I installed a Dubro 20 oz tank under the hood, with a 3 line system with fuel dot.

I suppose the new ST G-90 I have would be pretty anemic ?? The plane does have retracts.....

Two buddies on mine and I used to torment the local pattern flyers by flying in formation with three US60’s. We had a ball!

Later I bought a US1000 with the Sicker Tigre 2500 for power. My field required 98db to fly and when you choked the engine enough to get this sound level the engine was very cantankerous. I put 70 air hours on the plane before I sold it, the guy I sold it to still has it and is very happy with the 2500.

Anyway I felt the 60 was a much nicer plane because the 1000 had a shortened fuse. Well actually the 1000 was designed with a 72 in wing then they added 8in to make it IMAA legal. In turn making the fuse short. The tail power was never as good with the thousand as on the 60. Please do not get me wrong both were suburb planes.

If I had the option of a os 1.6 I’ld still have mine (the 1000, that is). I still have the 60 with 130+ air hours and I’ll fly her in about an hour.

On my Ultrasport 1000, I put a OS BGX 3500 in it. Boy did it fly!!! Didn't need much runway to take off and verticals were-out of sight. I also had retracts in it which were a nice touch. Had to extend the retract legs for prop clearance. Using a 18 x 10 prop.

My US 1000 has been a long protracted struggle, primarily due to engine issues. After much frustration with an ST3000 I went to a YS 120 FZ . I am firmly entrenched in the E flight camp but the YS 120 is my pick for the single finest RC product of any. I use a Mac Product Quiet Pipe with wisper quiet results.. It idles at 2800 and really pulls. It starts reliably and once warm, starts with a single hand flip.. The pressurized fuel system takes some extra care but delivers reliability. Ive seen the OS 1.6 in different apps.. I think it would work well here. I've attached a few pics, its my best work, a very complicated build but flies rock solid in a 20 mph wind...

Anyone know where I might get a canopy for the US 1000?

My Feedback: (9)

Your best bet is going to be calling Great Planes. They have parts for discontinued planes in stock. They don't have all parts for all planes, but they can tell you if they have it when you call. FYI I cleaned them out and got the last 2 US 60 canopies they had in stock!! If I remember correctly when I called them (last year) they said they did have US 1000 canopies in stock.

Give them a call and see what they have to say

A7bldr et al:

Believe it or not that was only my second RC project! what was I thinking?.... Yes the covering took many hours, I used metallic Monokote and chrome trim tape-5 colors in all. I even clear coted it to seal the edges.. I have come to prefer fabric and will probably use Solartex on my recover some day. In hindsite, this plane was as much about learning the building skills, tools etc as it was about the flying results.

So many planes go together straight and big. Done again, I would probably go with something prefabed but "YES" this plane was very much worth it and here's why:

Building is more than half the satisfaction of this hobby for me and this is very much a builder's kit. I build more than my share of ARFs but these days when people see and ask about the US1000 and hear its a kit build they often drop their jaw and say: "people still do that"? Its impressive on the flightline. I arrived a few times with a US 60 as well...that was cool.

I have 13 years with this project, hey, a Sonex or Sorarai or whatever won't be such a big jump, right.? Okok there's the costs difference....

Another reason: For all of us there's that one experience we have where we see a pilot or a plane and say- "that's me someday". For me it was Mr. Chuck Grinrod and his YS powered pattern planes practicing at our local club MARCS field. I was mesmerized by the sound of a quiet pipe and the grunt power of his YS's. Monday I flew the US with a 90 degree cross wind- nobody else

Now the US 1000 is on Hyde Out or whatever the current latest mostest is in pattern, but this plane has a solid smooth character and look in the air that's very distinct. I get goose pimply when I decend from a stall turn and it makes that giant scalle "whoooosh" sound. Other planes do that ofcourse but there's a lot of curves and carves on a US that make it an unlikely choice for construction en masse. I'm sure I'll be proved wrong on that one- the Chinese products are amazing to me.

Also, this is a plane that has taken some growth on my part to master and not too many of my projects have stretched me to improve as a pilot/builder like this one. (hHe others would be the IFO, Zagi and Shockys).

In the air this plane conserves energy well, and glides are long..landing attempts at high idle with a less than dialed in engine - well just didn't happen. I learned to raise the angle of attack with elevator for air braking, I added glow ignition giving me the confidence to run at very low rpm on final. Seems some added flap action would help the landing performance, perhaps a split aileron with a larger inboard section that function in 4 surface mode for aileron?

A couple other thoughts...Mac flex pipe should be backed off 1/4 turn when attached with RTV or silcone, that way it will have someplace to go if it needs to,-Otherwise breaks in the flex at the header will be a very common occurance on a soft mounted YS.

I have been flying a US1000 with a 108 for three years. I built the short wing and it weighs 10.5lb. The 108 with the stock muffler is fairly adequate but not great. It runs out of steam at the top of pattern style loops. I added a Macs pipe and am much happier. I have tried several props and get the best overall performance with a 14-8 Apc or MA Schimitar at 11400 on the pipe, 10400 stock muffler. I also increased the vertical fin area by 50%, much much better. Get the 160 or an ST140 and keep it lite. The bigger engines may have more power but they weigh an extra pound or more. They do become rockets but the wingloading gets too high for me.

My Feedback: (40)

Kweasel, how did you increase the fin area and why?
Jim

My Feedback: (29)

I added a 2" strip of 3/8" lite balsa to the LE of the existing vertical stab and built a new rudder fin. I built the rudder first because the stock one is completely ineffective at low speeds. If you try to fly pattern you'll find this plane takes a lot of rudder at the top of the box. It will still spin and snap but the rotation stops much faster. The best part of this plane is its wing, its thickness keeps the downline speed low.
