I dont think so. If I were going to buy an engine it would be the OS 55 AX.

I love mine with a saito 82.

Good plane for beginning and/or practicing pattern.

ii have a 50sx _(non heli) and a 61 fx.... i dont want to have to add too much tail wait if i use the 61fx .... ive pretty much scanned through all this thread and i havent come across anyone using a 61 in it, when you


according to os the 50sx weighs 13.76 oz (390g)
saito 82 weighs 16.32 oz (462 g)
61 fx weighs 19.42 ox (550g)
ys63 weighs 17.4 oz (492g)
if any, where did you have to add weight using your saito 82?

MTK

Mine needs 1 1/4 ozs tail weight with the ys63 up front...even that is a bit nose heavy. Model still pitches to canopy ever so slightly in knife edge. Up and down lines pretty close. Oh yeah, rudder servo is in the tail too.

The Saito would probably need about 1 oz in the tail.... would about make it perfect. The smaller 2 stroke is probably the best ticket all around and should be plenty of power. The 61 fx is probably overkill but if that's all you have use it

My Oxy came in at 5 lbs flat, the tail weight included. Flies with a nice feel at this weight.

My OS 50 SX's have as much or more power than OS 61FX I have. Also have 2 OS 55 AX's and they Out Perform My OS 61 FX. If OS 50SX is broke in it's a Awesome Light High Performance Engine. The OS 55AX turn Bigger prop and APC 13 X 4WIDE runs great on it. I think it would work great on any Pattern Bird. I'm mounting one mine on 42" Ultimate Bipe and Other on Showtime 50. My Pulse XT has OS 50 SX in it and My Fliton 330 Extra Feestyle has OS 50 SX in it. I think OS will Drop OS 61FX soon. I was surprised when they dropped 50 SX so I whent bought 3rd one while I still could get one. OS 55 AX 525 Grams with stock muffler or 405 Grams compared 550 grams the OS 61FX weights. 50 SX may give You more Top Speed but less Power than 55 AX because of props 55 can spin. The lighter You keep Your Plane the better I think You'll enjoy How it flies. It's No Brainer to Me. I'd use OS 50SX and Experiment With Props. I run 15% Morgan Cool Power in All My engines. Hope this helps???

Metallicajunkie, there's a guy on a Dutch forum who just started flying his Oxalys with a 61FX on it, flies great he says. Then again he's only 14 years old and his previous plane (first plane?) was a Calmato. Anyway the replies there are the same, it needs quit a lot of lead in the tail. Why put a bigger engine on it if the extra power is only used to transport lead? In the same thread they talk about a 91FX being lighter than a 61FX, so if you really want to overpower it better go for the 91. Personally i think it is better to go for the 55AX. The 50SX (wich i am using) is no longer in production. If mine breaks down i switch to the 55AX. By the way, mine's the one on page 14 with the tuned pipe, it is now currently being overhauled, i'm giving it a new Oracover jacket.

I didnt add any weight with my saito 82, I did make a hatch in the back of the fuse for the battery and balancing. You could mount a servo in the tail and it should eliminate the need for weight. If you already have the 61 use it.

Dear Metallicajunkie, please note:

OS 61 fx:
http://www3.towerhobbies.com/cgi-bin...CH=OSMG0561%29
Weight: 19.4 oz (550 g); 23.6 oz (670 g) w/muffler

OS 55ax
http://www3.towerhobbies.com/cgi-bin...EARCH=OSMG0556
Weight: 14.29 oz (405 g) w/o muffler; 18.52 oz (525 g) w/ muffler

The YS 63S weights 17.4 oz (492 g) and includes muffler.

I don’t know the 50 AX muffler weight, but I believe the silencer weight around 4 oz (113 g). I suggest you make a hack for servos and battery and install in a more backward position, so you can balance the Oxalys 50 at right. Use your 50AX and try a APC 12.25 x 3.75� propeller.

Mingo, this is a precision pattern plane. I seriously doubt that prop would be any good on this plane. This plane wasnt meant to hover.

Minimum pitch I have used on mine was a 12.5x7 MK, Its happy with a 13x8 apc, with my saito.

MTK

I am using a 13x8 apc with the YS63. Goes a bit faster than it should (for pattern schedules) but not really a problem. A 14x6 may be just a bit better to manage speed easier

I don't care at all for the stock landing gear. It positions the wheels too far aft. The tendency is to nose over too easily off the grass where I fly. Probably isn't an issue on paved runways, but is off grass. Also don't care at all for the covering. It's already peeling off after only 10 or so flights.

But a decent flier all in all

MetallicaJunkie

great, then that settles my doubts about using the 50 sx, i use coolpower too, its the best fuel i have used and at a great price locally, even my fourstrokes like it

BTW you have a nice collection im trying to work on mine
and thanks to you and everyone else's advice

MetallicaJunkie

nice covering job! after reading richgrows reply i have decided to go back to the 50 sx, it has always run great, and doesnt have more than 15 taks through it, so its still somewhat fresh


ohhh your the one with the purple pipe that what inspired me to go tuned pipe thanks.....

MetallicaJunkie

thanks for the info, and correction

MetallicaJunkie

sorry ive been posting like a wildfire on this thread ....... im on a slight budget could i use the mighty minis? or is it best i use std size servos?

Jeff Boyd 2

Depends on what "mini's" and what "standards" you are looking at . .

I am thinking if you are on a budget, probably any quality standard (analog) servo will be OK (as long as it is over 3kg/cm torque rating). I am not sure of any mini's I would use on this plane (on a budget) the better quality MG Mini's with a torque rating of over 3kg I think would be Digital . . and I expect that would blow your budget ! !

Cheers, Jeff

MetallicaJunkie

i would love to use these if i could fit them with out modification http://www3.towerhobbies.com/cgi-bin...&I=LXN667&P=SM thats the max im willing to spend

my reasoning for wanting to use the mighty minis is mainly because of its speed and relatively hi torque for its size plus it has metal gears has any one used mini servos on the oxalys?

MTK

Just a bit more on the Oxy with the YS63 up front and rudder servo in the rear. The model is still too nose heavy even after removing the Tru Turn spinner. It will need at least another ounce of tail weight to fly right. This is critical if you ever expect the model to fly with minimal effort, particularly diagonals and knife edge flight.

Knife edge is very close...another ounce in the tail and it should fly practically perfect knife edge, ie- no mixing. Two ounces if I put the spinner back on. The climbing diagonals such as reverse Cuban or 45 deg up snaps, in general, tend to flatten too quickly because the model is too nose heavy. The ideal set-up will allow the model to fly the correct angle especially after rolling on the diagonal line is done. Inverted flight requires much too much down elevator and landing can be more difficult than it should be.

All of these things will be fixed when I get the cg perfect. Flying the Masters schedule is a bit more demanding of set-up. If you aren't using the model for serious practice then your set-up will probably be fine as you have it. I feel that there's quite a bit of capability that I can extract from the model so I am being almost as fussy about it as I am with my 2 meter designs

Oh, btw, I installed the landing gear backwards (moved wheels forward) and that eliminated the tendency to nose over when taxiing. The gear worked fine like that. The look difference was observed but wasn't hardly noticeable

Dear SuperD

Thank you to remember me Kyosho Oxalys 50 is a pattern plane. I had one with AXI electric motor, one with Hacker electric motor, one with a YS 63S 4-strocke glow engine and another one in the box, this the new series, with a T canalizer. The tree planes had a very different flying style with the mentioned engines. All the planes are used in experiments for use a small and cheap plane to training F3A pattern flying. I don’t like hover with planes, any type of plane. Hover is for helicopters.

I only suggested a very low pitch prop for the OS 50 maybe for some experiment, since in another time and in another pattern liked plane a used a 12.25 x 3.75 propeller in a Webra 50 2-stroke glow engine with good – not very good – results, since in my opinion the better glow engine for Oxalys 50 is a 4-stroke. In this sense I believe the OS 50 can perform like the Webra 50. Really, I don’t know how the Oxalys 50 will fly with a 2-stroke engine.

best regards, lineu

Super D

Fair enough, I just wouldnt try anything less than a 5 pitch. The engine would be screaming and if there was any wind the little oxalys wouldnt have much speed to penetrate the wind.

hezik

a small pitch shouldn't be too much of a problem. 13*8 on a Saito FA82 is too big.

The Oxalys doesn't need much speed at all, it can fly real slow. Flying it at high speeds would be a waste. I was using a 14*6 on my Saito FA82 and wanted to switch to 14*5 or even 15*5 or 15*4, depending on what the engine would handle. Switched to a 2m pattern plane instead. Which doesnt fly that much better than the Oxalys (offcourse it's less affected by wind), which proves how good a 'small size pattern plane' the Oxalys really is.

bbagle1

I am planning on buying my first pattern plane and i am looking at this plane as well as the world models spot-on 50. I will be using a ys 63 for power. Anyone who has flown both have any input? The world models plane is much cheaper but if the Oxalys is really that much of a better plane I would rather go with it. PLease let me know.

MTK

About the only disappointing thing about the Oxy is the crappy covering. That subject has been covered ad nauseum already so no need to get into it again. Everything else about the Oxy is super in my opinion.

MattK

bbagle1

So do you think it is a much better plane than the spot-on? I am mainly concerned about the performance not being up to par on the spot-on. There isn't much info on it on RCU

MTK

Hard to get much better than the OXY for a small plane. I am not saying anything against the Spot....just saying for the Oxy
I have a YS 63 in mine and it does a pretty fair job in practicing the Masters and F3A schedules. If you don't fly those schedules and don't much care about that level of performance, the Spot could be just fine.

All I am saying

Hello Smok,
I have flown Matt K's YS 63 powered 50 sized Oxalys. It flies absolutely superbly!
http://www.kyosho.com/eng/products/r...roup_id=100036
I am considering getting one for off-season practice.

Oh yes, welcome to the event!
