Nickolas,
everything looks fine, buy check you prop selection for this particular engine on www.osengines.com
Thanks
Asif

Hi asif,
great! i thought that the bend wasnt enuff to bring the header to the top so that the pipe will be aligned level with the plane, anyway my header will be coming in next week, so really excited about it and will post pics of mine as well.. =P

Thanks Asif,

This is a brilliant looking plane, probably the nicest looking ARF I've ever bought. Yesterday I ironed the covering bubbles where needed. This material is pretty iron friendly, it looks almost perfect now. Be careful with the silver stripes, they shrink a lot more than the other colours.

As far for the servos I'm going for coreless on Elevator rudder such as JR-4231 or 2235, I'm gonna remove them from another plane.

APC 13x7 will do the job with 30% nitro, I hope ground clearance is ok.

Please send the flight report when you fly it. It seems this plane will have negligible pitch/roll coupling, what is your experience?

Rgrds,

Nick

Nick,
I flew one yesterday for one of our club members and it flys great... This one has a YS 63 for power with the new short Hatori 640 muffler from Central Hobbies. We ended up adding about 3 ounces of weight to the tail to get it to balance. It was still a little nose heavy for my taste.

Servos were JR 811 digitals for everything but the throttle. 13 X 6 prop, Unlimited vertical. It flys very close to a 2 meter plane. Very little mixing required.

Joe Dunnaway

Hi Joe,

Where exactly did you balance it on the recommended CG range? Probably it came nose heavy because of the pipe. I would not rather to put tail weight, if this is the case I will even remove the muffler of my OS 70 Ultimate and I will let it with the manifold.

Rgrds,

Nik

Hi Nickolas
Well finally I flew my Oxalys yesterday.....IT WAS EXCELLENT!!!!! perhaps its one of the best planes I have ever flow. The way that I have setup, CG came out to be perfect, no trims required for straight and level flight. Inverted flight required just a touch of down elevator, I will add some weight to the tail so that I dont have to hold down elevator.....
I am using 13X6 APC with wild cat 30% nitro heli fuel with 23% oil content.... higher oil content is is extremely important.
Although I am running the engine richer as said in the manual.... I still got very decent vertical.... Oh by the way no rudder required for vertical!!!!!
YS maual calls for 20 flight with rich settings, therefore I cant push the engine to its optimum to check the vertical, but I am sure it has plenty of power.
I am flying off the grass field and prop clearance is plenty, I was little concerned about wheel pants and relatively small foam wheels too, but they worked just fine.
Next week I will explore rolls, loops and knife edge...... will update then.
Thanks
Asif

Hi Nick,
The first flight was on the forward edge of the recommended CG. After adding 3 oz. to the tail it was closer to the center of the recommended GC. Shifting the battery back under the the servo tray should get it to the right spot.

Alpha11 is right. This is one of the best flying small pattern planes around. Knife-edge requires very little rudder and rolls are very axial.

The only weak spot may be the landing gear. It seems to bend very easy. CF gear would be nice.

Joe

Joe and Asif,

Thanks for the responses! I'll probably fly it this weekend I have a fresh Cool Power heli 30% bottle waiting for me. Don't have to break in the engine, is already broken in.

Did you use the stock hardware? Any issues? I am starting building tonight that's why asking.

I'll send some photos soon.

Rgrds,

Nick

PS: By the way Cool Power Heli 30% contains 22% low viscosity oil. Just for your info Asif. .

Nickolas, yes cool power has 20% oil, but WILD CAT 30 Curtis Youngblood special contains 23% klotz synthetic oil

Nickolas,
I used stock fuel tank, stock throttle cable and stock push rod. I used dubro adjustable control horn (tower stock # LXD932) on ailerons and elevator, with metal clevis, this will give you more precise control. Stock pull pull will work fine but I used dubro. I also used stock pull pull horn.....very simple but effective.
To my experience aircraft is not a floater...... you have to bring in with a notch or two of power and ideal when you are 2 feet off ground. I may me wrong as there wasd slight wind yesterday.
Thanks
Asif

Cool Heli 30% contains 22% low viscosity oil, I have been using this on my OS FS-70 Ultimate, YS-140 and will be using on my new YS-110. It is strongly recommended for YS. Cool Power Pattern Pro contains 20% high viscosity oil. Check their website if you are not convninced.

Rgrds

HI NICKOLAS,
I MISSED YOUR POINT.... ARE YOU SUGGESTING THAT WILD CAT Curtis Youngblood Performance 30 Heli Mix IS NOT OK FOR YS ENGINES? CUZ IT HAS 23% synthetic oil AND 30 % NITRO....
THANKS
ASIF

Νο if it contains 20% or more oil then it is ok for YS. I was mistaken I thought you wrote Cool Power Heli instead of Wildcat Heli. Cool Power contains 22% and Wild Cat 23%. I have never used that fuel as it is not imported in my country. If it is good for Youngblood it is good for you and me. I mainly use Cool Power Heli 30% Nitro and 22% Oil on my 4 strokers with no problem. Cool power Pro Patern is difficult to be found in my country so I use Heli type which is more than ok for the application. Their only differences are oil content and viscosity.

Anyway back to the Oxalys discussion. One of my ailerons has some warp, I had the same problem with my H9 Showtime. I'm a bit unlucky with ARFs lately. Anyway I'll see what I can do with it tomorrow.

Here's is a photo prior to assembly.

Rgrds,

Nick

Hi Nickolas,
so you are getting there with assembly..... if you built it right you will love this aircraft. as far as aileron is concerned, contact the hobby store that you got from or you can contact kyosho usa.
thanks
asif

Yes I'm getting there . Hope to finish it soon. Here are some photos of my progress. This fuselage is pretty wide. Seems that modern pattern designs have very wide fuselages. Fin is not located very high with respect to the fuselage axis, this must be related to roll or pitch coupling may be. Just compare with my Robber Saphir I 60 on top of the photo, no comparison in the design philosophy.

Can someone give us an explanation of this design tendency?


Rgrds,

Nick

how does this airplane compare to the Cermark Javelin ?

The javelin has a longer fuse and the wing on the javelin is larger. 61.5" (fuse) 58" for the wing.

I think the Kysho Oxalys 50 has a 53 3/4" wing and a 57" fuse.

by the way... The Javelin II is about $80 less than the Oxy 50.

Nicholas and Alpha

If you want to put a 2 stroke and a pipe you would need to make a tunnel below the wing, is that posible?, because looking at the pictures there is only a small place that is designed for a mini hatori pipe for the YS 63

Thanks

I think it is possible, the wing has something like a dummy belly pan made of balsa wood. You glue that thing to the wing in order to give a mid-wing location impression. However, you can put some fuel proof to the inner side and cut in accordingly. Then you can screw to the wing a ring with a special nut for tuned pipe and place the belly pan over it with screws. If I were you I would put 4 little pieces of hardwood with blind nuts in order to hold the belly, do not use just wood screws on the hard wood as they will become loose with vibration.

Good luck, if you want some more info on the plane construction etc. you can download the manual from Kyosho web site.

Rgrds,

Nick

I've built and flown both models. Both models use the YS .63. The Javelin is a good airplane. The Oxalys is outstanding. Closest thing in this size class I've flown to a good 2 meter. It's that good.

Nickolas:

Thanks forthe info...i can not download the manual of the OXALYS it doesn´t download completely, i dont know the reason i hava good computer and the last version of the ACROBAT.
Well.....so let me see if i understand you.....you told me that i can put the pipe over the wing and then over the pipe install the belly pan?? is that correct? or to glue the belly pan and then cut it until i could make a tunnel bellow the wing?
I can buy the YS 63 but i already have an almost new YS 45 with a hatori pipe and it is a very good engine, that the reason i am asking because i need to make a desicion very soon!

Thanks again, i would appreciate more pictures of the bellypan

Erdel,

It looks like Nikolas talked about rear exhaust setup. You are talking about the side exhaust setup that gets the pipe installed on the side of the fuselage.
Is your side or rear exhaust? I don't remember.
I have the PDF Oxalys manual, I can E-mail you directly (14MB)

I forgot to talk about another possibility.
Get a wrap around header from Karl Mueller ([email protected]). Then you should be able to get the side exhaust YS 45 to fit on the Oxalys 50.
If you need more on how to, let me know.

Ihncheol Park

Incheol:

My engine is side exhaust and i was thinking to put the engine 8 o´clock position so the header and the pipe would be exacly below the wing. I think this is the best option. That was the reason i was asking for the bellypan issue.

Another option could be to put an OS .46AX that i too have it in stock and buy an UltraThrust Muffler and put the engine inverted and the muffler from one side and it is a pretty muffler!

I would appreciate if you could send me tha manual via e-mail to my personal mail:

[email protected]

Thanks again for your help and i would accept suggestions!

if u r gonna use the OS 46 AX, save the trouble and just use the stock muffler, it is more den enuff power unless u r looking at e issue of getting oil all over the plane.

Here are some photos of the belly, you may have some problems with your manifold , have a look at the 2nd photo. You propably have to reconstruct this part in order your manifold to pass through.
