Mr. Mugen -> Ailerons on stinger 10 (1/21/2008 5:57:12 AM)

Did anyone use bigger ailerons on their stinger 10? They just look so out of proportion. I know it's a trainer but it seems like they are still too small. Is it just me? How does it roll? Fast, slow?

I got the tail feathers on and secured and wing joined so far. Looking to finish it soon.

Also, what servo's are you's using? I see in the pics they show standard servo's. There is no way I am doing that but was curious what you's run. I was thinking hs-81's would be suffice.

Umm, never having had a Stinger I could not say specifically, but if it is a trainer I doubt seriously it will roll fast. A trainer should not do hardly anything fast to give the trainee more time to react to common situations. Also for those uncommon situations!

Are you wanting fast rolls? If so are ya sure you need a trainer? Or do you want a trainer that will bore huge holes in the sky while rolling like a high speed drill? If you want performance that is not like a trainer, there are plenty of others available.

Generally it does not take very much to make a plane change attitude in the sky. Large control surfaces and large deflection of these control surfaces is not warranted unless you are trying to do more extreme flying.

There was a related question titled "Control Surface Deflection" recently here:

I hope this sheds more light.

Stinger 10? A trainer? What gives you that idea?

No Dihedral
Symmetrical airfoil
Big Flippers
High wingloading

third airplane at best

It shows full size but the picture is not right. You have to use micro servo's is put in HC81's and had to redo the openings. They are not long enough. So make sure you redo the aileron cutout before epoxing in. I also striped one HC81 on the wing and went to HC81MG for it. Measure the opening and try to find something that fits or rework the openings now.




Mr. Mugen -> RE: Ailerons on stinger 10 (1/21/2008 2:54:06 PM)

Welll in the description it was called a mid wing trainer. I dont make this crap up. I do not need a trainer either so yes a faster rolling bird is what I am after.

Any chance anyone has one that has bigger ailerons that can pipe in?

I plan to use 81's for sure. I do have a few extra gear sets here to convert one to MG.

Anyone?




combatpigg -> RE: Ailerons on stinger 10 (1/21/2008 4:42:21 PM)

MM, I agree that little stubby control surfaces don't look right. They aren't as effective for finite control in some applications, they can get masked by the airfoil easier. A flap with more chord will enter the slip stream sooner, with less angle involved. This contributes to smoothness over using those stubby airbrakes. For a 1/2A model, 7/8" wide is as low as I go. If you can work it into the Stingers' design, then go for it.




BMatthews -> RE: Ailerons on stinger 10 (1/21/2008 6:11:30 PM)

The Stinger has been around for years. In this age of slow flying 3d models the surfaces do indeed look way too small. But this is not a model intended for slow flying 3D stuff. It comes from the day where the models were intended to be flown fast and furiously. Keep the speed up to a reasonable rate and it'll fly and snap roll just fine assuming you use around 30 degrees of throw either side of neutral. Even near stall it'll have lots of authourity although, again, it won't have the snapiness of the 3D models.

The benifit is that you're in far less risk of flutter at the higher speeds with the narrow surfaces.

And regardless of what the box says it was never intended as a first aileron trainer although I suppose with reduced throws it could be.




combatpigg -> RE: Ailerons on stinger 10 (1/21/2008 6:45:23 PM)

To illustrate a point with extremes, set up a 9 " chord, 1" thick airfoil flying wing with .5" chord elevons......fly it a few times and note how it behaves from the moment it leaves your hand, 'till the time it lands. Then add another .5" chord to those elevons and take note of that. I think the broader flaps make the plane groove better.




Mr. Mugen -> RE: Ailerons on stinger 10 (1/21/2008 8:13:04 PM)

Well it has a 7 3/4" chord and a 3/4" aileron. I suppose with the intended speed it will do fine. I am putting a OS.10 in it. I am sure it will be fine or they wouldn't have made them for as long as they did. Just a weird look I guess.

Kevin

Now that I look at the old warlock the it looks the same. I guess the design of the era shows here. I think it's growing on me.




hfenn -> RE: Ailerons on stinger 10 (1/21/2008 8:32:29 PM)

I had one back in the 90's and powered it with an OS Max .15. It was plenty fast and mauverable, I lost mine doing outside snaps in a dive (throttled back, I would usually hold that till it broke into an inverted spin) when the wing mounting block ripped out. Check that and reinforce as necessary. Mine was back when the Futaba S133 was the micro servo (they look huge now).




NorfolkSouthern -> RE: Ailerons on stinger 10 (1/22/2008 12:46:31 AM)

So, does anybody have photos of this plane? I once started on a kit, but had to sell it. I am thinking about another one, possibly the ARF that's on sale at Tower Hobbies. Any experience there? Is there no demand for this make and model, either in the .10 or .40 size? I suppose the trend these days is in the U-Can-Do 3Ds and Mustangs (everybody and the neighbor's dog has one).

Stock photos only --






Mr. Mugen -> RE: Ailerons on stinger 10 (1/22/2008 2:34:49 AM)

I need to recover mine. I do not like the covering scheme at all. It is a rainbow......




NorfolkSouthern -> RE: Ailerons on stinger 10 (1/22/2008 3:03:36 AM)

Andrew: I was not referring to stock photos, sorry.

Andrew -> RE: Ailerons on stinger 10 (1/22/2008 3:40:01 AM)

Sorry, those were the only ones I had on file.





Mr. Mugen -> RE: Ailerons on stinger 10 (1/22/2008 4:05:20 AM)

Here's a few pics of mine.




NorfolkSouthern -> RE: Ailerons on stinger 10 (1/22/2008 9:31:22 AM)

Mr. Mugen: Thanks! Yes, that's exactly what I was hoping to see. I'd like to buy both the 10 and 40 that are on sale at Tower, but I doubt I'll be able to afford them before they're sold out. Here's hoping!

It's the thought that counts, Andrew. Thanks. I do like the color theme on the prototype Stinger 10 kit, it looks simpler and more dignified than the ARF. According to Mr. Mugan's photos, I did notice a difference between the two (kit and ARF). The kit has an ABS turtledeck, wing cover, tank cover, and cowl. It's not bad to work with, but does require some fiberglass work, which I've never done and the parts also need to be painted. The ARF, however, is of wood construction and apparently has a built up wing, rather than foam core. It'll be interesting to see how it flies!

Mr. Mugen -> RE: Ailerons on stinger 10 (5/8/2008 4:12:29 AM)

Well I finally blew the dust off this thing nd finished it. It is maiden ready now. I was wondering for you folks who have this plane, what is your AUW? I am running a OS 10 and hi 81 servos and am getting a dry weight of 2lbs 3 ozs. I just feels heavy. Is this a flyable weight? I need to find the formula for wing loading again. The manual does not tell you wing area or anything for that matter. Maybe a maiden tomorrow if weather allows.

I do not have the .10 size, but two Stinger kits I have had my hands in surprised me with the all up weight, meaning they were heavier than I thought they would or should be. But they fly like the dickens, in some ways like a Hots with a less funky fuselage design. Your thought that it must work is sound, many have been built and flown and it is a proven design in the various sizes. It is likely true that the .10 size would benefit from a .15, since most .10's weigh about the same as the .15's anyhow, or close enough to justify the 50% displacement increase. However, yours should fly fine as is, give it a go. Depends how important vertical is to you.

On small airpanes there is less aerodynamic and inertial damping and the stock ailerons will give you a good roll rate. However the comments before are also sensible - this is an era of slower airplanes with radical control surfaces and throws, so this model may look odd to you. Increased chord may result in more joy, dunno. Just watch for flutter, which if you are using appropriate servos with good linkages should not be a problem. Sealing the aileron gap (or all of them) will help with control authority and resistance to flutter. You sure do not need standard servos! Don't go too small though, while the torque rating may be sufficient, some have lighter gear trains that take a beating on a glow ship. Mini or strong micros, no sun micros. Like hfenn, on the last couple of models I built in this size I used Futaba S133's as well.

Wing loading is simple, esp. on Hershey bar wings: if you want loading in ounces per square foot, measure the span and chord in inches, multiply the two, and divide by 144 to get square feet. Weigh the model in ounces. Divide weight in ounces by wing area in square feet, to get wing loading in ounces per square foot. That's all there is to it.

Curious: what prop do you plan to use on the .10?

combatpigg -> RE: Ailerons on stinger 10 (5/8/2008 1:50:53 PM)

Hmmm, at 35 ozs I would check to see if any tools got accidentally left inside the wing or fuselage.

LOL

I have a half built Stinger 120, it's one of the 47 casual projects on the go downstairs. The wing is nice and light but the wood in the fuselage and tail feathers borders between medium-hard and ebony; so I am picking away at it to lighten those sections up. I read a review not too long ago of the 120 and the reviewer's model came out something like 2 or 3 pounds heavier than the mfr. specs.

So I can imagine how the .10 size could be on the porky side. A .15 will fly a 2 pounder okay, I imagine the .10 won't exactly rip it to shreds but hopefully it flies alright. If not, out with the .10 and in with the .25. I'd aim for the 25 ounce range for a .10 size model, or lighter if possible.

Another model I have downstairs is a Birdie .10, that belongs to a flying buddy. I pulled out the OS .10 that looked lost in front, and am pondering what engine to replace it - he has an old OS .35 Max that I am seriously considering, but likely I'll attack it with small hole saws and the Dremel to carve out some useless weight, and fit a .15 to it. The fuselage is about the same size as a Q500, but weighs a ton - 1/8" ply doublers, heavy this and that, and the builder seemed to have ample epoxy on hand. I could mount a .50 on the front and the fuselage would handle it, although the wings would flutter off seconds after launch. So.. I wonder what the designer thought a poor little .10 was going to do to it. It feels like it would survive a vertical dive into the dirt, or a .10 at full throttle with one blade broken off. I can imagine how much better it would fly with 1/2 - 3/4 pound shaved off.

I'm always amazed at the broad spectrum of opinions and expectations with respect to weight, wing loading and overall flying capability. So far everything I've ever seen offered by Lanier has been at best mediocre, at worst unusable. I think the Stinger was designed by a guy named Bubba Spivey? Guys named Bubba should stick to designing earth moving equipment and freight train suspensions, not small model planes [;)].

Oh, my! Look for posts on the Lanier Laser (quarter scale). Mediocre? Nahh... fine flying specimen. Capable and stable. There are other posters who have said the same, I recall posting in a thread where someone called it "boringly neutral". As in, inverted, almost no down elevator required. Knife edge with very little rudder.

Of course, I also loved my TR260 - the ancient plastic one. Flew about like the Laser. Just my 2ยข worth,
