Status: offline 		Thanks Zor. What you are saying is pretty much what I thought.
I'm not out to fly 3D with my US60 but I do want it to fly vertical until I pull back on the throttle. I don't think a .61 or the .75 is capable of that on an 8lb airplane no matter what prop I put on it. I also don't think the FS .95 would do it either. The .95AX may be capable but I can't go larger than a 14" prop.

I have been told by some of the guys in my club that I'm barking up the wrong tree without a paddle

Try measuring the thrust with the plane tethered to a fish scale and engine / prop full throttle, you'd want to see the fish scale reading more than 8lbs (at a quess I'd say about 30% more) to get 1 to 1 thrust.

The 95AX is going to give you all the vertical you need for sure. I would see the down sides as prop diameter and torque roll. When you snap the throttle open, I'm picking the plane will want to roll around the engine a bit. My Tower Kaos at just over 5lbs with a 55AX does this, especially on a landing overshoot from a slow air speed / low throttle to instant  full throttle, upsets the plane a bit if you bang the throttle in to fast. It's not an issue at higher air speed.
 
I've also bend my own 3/16 wire gear and lengthened it 1 inch even for the 13 inch props I use with the trike gear configuation. The 3/16 diameter is way stronger than the kit 5/32 wire gear.

Cheers,

Gordie.

My US60 with OS-.75AX,APC 14X8, Spring air main gear retracts with 3/16" struts, weighs 8.125#. I can fly straight up until I pull the throttle back! A larger engine may give more power but the prop diameter will be limited by the gear length. A larger engine may also add nose weight that may require tail weight to balance, thus increasing over all weight and reducing thrust to weight ratio. Try the OS .75AX/APC14x8 combo you will like it.

Status: offline 		Ok, I'm convinced, I'll order the .75AX. I have been worried that the .95AX would make it too nose heavy and prop clearence for a larger engine will be an issue. My landing gear is 5" from the bottom of the wing to the axle which should give me about an inch of clearence with a 14" prop.

Status: offline 		My US60 has a Tower Hobbies 0.75 engine with 12x6 APC. Last time I checked, it was pulling over 9 lbs of static force (WOT) checked with a fish scale at the tail wheel . With a dry weight of 7.0 lbs even, she goes unlimited vertical at 3/4" throttle. An US60 at 8 lbs would not be a problem either.

Hello Gordie,

The following is written more for the general reader.
You probably know this already.

The speed of the human being nervous system communication is such that reaction time is typically one half (1/2) second. The fastest ever measured was one quarter (1/4) second.

For that reason it is best to apply the throttle smoothly in about a two second motion so that if unexpeced model motion takes place then the pilot is able to react fast enough.
Instannt full throttle is not recommended.

Comparing 3/16" dia wire to 5/32" dia wire, the 3/16 is 1.440 times stronger if made of the same material and heat treated with the same procedure.

Have a great day all.

Zor

Hi JNorton . . . long time no see you.

There is a reaction time testor on that site.
I had seen this site a long time ago or a similar site which is from where I remembered some values.

Just tried this site from your posting and I averaged between 250 and 300 ms.
Perhaps typical for an old fellow   .

I had started this kit as my first kit around Feb, but life got in the way with an illness leading to death in the family, so on...

got out to the field for the fourth time this year last sunday, and a buddy had a US40.  He let me fly it, and let's just say, I have now been "re-inspired" to dust off the sanding block and 11 blade and "get back to work."

Status: offline 		A couple of months ago the battery came loose in my US1000 and the plane was destroyed. I was so depressed, I didn't fly for a month and almost quit the hobby.

However a couple of weeks ago I was luckey enough to buy another 1000 that I found on this site. I'm gonna stick with the OS 1.08 from the first plane.

I have flown many plane but the Ultra Sport is my favorite. Flys like a pattern ship and lands like a trainer. I'm not a builder but I love thewse planes and would be honored to join the brotherhood.

The blue one was my first one :-(.  The white one is the new one.

Status: offline 		Thanks, I'm kind of partial to the two  tone scheme of the blue and white. It reminds me of the classic pattern ships of the 70's. It was beautiful. I couldn't find out who built it but I would like to shake his hand. I still have the shattered pieces in a big box. I might try to see if someone can rebuild it for me. I just can't do it. 

The white one with the blue, yellow and red trim was built by Dennis Sarette (hope he doesn't mind) of NH. This guy is a master builder and coverer. To say it looks factory would be an insult.I hate to admit it but this is actually a better plane than the old one. It has wing filets, pull/pull rudder, oversized landing gear, and some other goodies that the other one didnt have. If you buy a plane from this guy, it's going to be top quality. I'll try to post some more photos in my gallery.

Yours are nice also. I would love to have a 40 or 60 in my hangar that I could fly when I dont feel like lugging out the big guy.

Status: offline 		OK guys, I wana be in too!  I guess I would be #140.  I own a US40 that I built and flew a lot back in the early 90's.  What a great flying plane.  But back then I also purchased a 1000, ST2500, and acquired OS108.  I've just decided to finally build the 1000.   But from what I've read, the engines I have may be a little small.  So I've been looking at an OS160FX.  It's the same weight as the ST2500 and puts out 1hp more.  So please tell me what you guys think.  I wanna do the right engine and retracts too.  Happy I found your group.   Rich

I was thinking of going to a 160 twin, but not in the mood the cut and redo the front so maybe a Saito 150 or YS 140 instead.

I'd still like gas (DLE 30?) but havent found any real feedback from anyone who has done that plus not sure if I have enough prop clearence with the exisiting gear.

Status: offline 		I have an OS 160fx 2 stroke. I also have a dle 20 and 30 but I think the gas engines will require too much of the nose to be cut away to fit around the gassers and it just wouldn't be an Ultrasport anymore. Love my gassers but the Ultra needs to keep its lines I think!!
The dle 30 swings a 19/8 prop so clearance would be bad also. I am running this engine in an EF Yak 74" and it has long gear so no problem there.
