Status: offline 		I understand why you would like to have duel servos on the ailerons but I’m not sure how you will be able to do that easily if you plan to put the servos out in the wing with the pre-covered wing. One solution is to put both servos side-by-side in the center of the wing but you lose some of the duel servo advantages. I have a kit built Tower Kaos 40 with a single servo on the ailerons using a tight linkage setup and it works fine. On smaller aircraft a single servo should be all you need. Back in the “day” we used a single servo on all of our aircraft. On the other hand if you really want duel servos placed out in the wings it can be done but you will need to replace some of the covering on the wing after you cut it away to build the servo mounts. The covering used on the Tower Kaos ARF is strange stuff so I’m not sure what covering would be compatible.

Status: offline 		gjhamp,

I'll have to agree with 8178. Dual aileron servos on this plane serves no real usefullpurpose. I've flown this plane both ways and there is really no noticable difference in the way it flies. I had a Tower Kaos kit that I converted to dual aileron servo's and it was a real pain in the a__. As far as the ARF goes, other than the covering issue 8178 brought up, the ribs in the arf have very large openings in them which is what you don't want when you are trying to mount a servo between them.

The Kaos arf is such a nice flying plane as it is, I'd suggest you fly it like it is.!!

Using two servos side by side in the center would probably be easier to do. I installed the aileron servos in a 40 size MT Lucky Stik this way to play with ail/flap/spoiler mixing. It worked fine but I don't use the mixing any more.

Status: offline 		Thanks for the advise 8178 / hrccflyer I will give it a try with the single servo, I am still learning about setting up planes and since alot of the pattern planes seem to come with dual servos I just thought I needed them on the Kaos.

Thanks.

Status: offline 		I would agree with the above advice to go single servo. I have the Tower Kaos Arf with a 46 OS in it. I, too, decided to just build it with one servo. Flies great. You'll love the plane just as it is.

The best thing you can do for your Kaos is to use the innermost holes on your servo arms and the outermost holes on your control horns. This is what makes planes fly smooth and precise, not dual servos. And, set your EPA's to 100% because you want to use as much servo travel as possible for precision control.

The first (or second) time that you build a model with torque rods that permit oscillating ailerons in flight, you will forsake torque rods forever. Don't ask how I know. Well, you won't have to. I'll tell you.

I built my Bridi Deception kit in 1982. I used an OS.61FSR ABN engine, a Kraft KP7C radio with KPS-15 servos fitted with Giezendanner wipers. I also used Rhom Air tricycle firewall mount nose gear (never again) retracts. Like an idiot, I used the stock aileron torque rods. They looked as good, or even slightly better than any other torque rods I have used. They installed easily, felt really solid and surprised the dickens out of me while flying by in a high speed low pass. They were humming badly. The OS.61FSR with a Mac's header and OPS aluminum pipe was booking along at a good clip, but I didn't think it would be anywhere near fast enough to cause aileron oscillations. Now, this model represented a lot of work for me. It challenged me in ways that I didn't think possible. But it turned out to be a decent flyer, once I reinstalled a new set of torque rods and ailerons. I asked my mentor if he thought it wise to simply do away with the torque rods and put the servos outboard in the wing. A first for then. No one else was doing it that I knew of. I had had it with torque rods. I was advised not to make the move. So I didn't. It was the only bad piece of advice that my pattern mentor ever gave me, so I can't complain.

Naturally, after having the ailerons oscillating badly, I inspected and replaced the gear train in the KPS-15 servo. It turned out that they really needed replacing. Since then, I almost never use torque rods in model airplanes. If I do, it is only in planes that fly very, very slowly.

The Tower Kaos ARF is not what I consider to be a slow airplane. With that said, I'm not saying that the stock torque rods won't work with your model. I'm not saying that you shouldn't build it stock. After all, you might get away with it, so why bother? I am saying that if you have a problem and decide to retrofit the wing with dual aileron servos, give a yell on the forum here and lots of us can guide you through fitting separate servos into the wings of your Kaos ARF.

I watched the video (again, I saw it before) and your engine does not sound like it is really turning up all that high, but, the model is flying very quickly and it has very impressive vertical capability.

Now, I realize that the Super Kaos 40 kit (Bridi) was a small model, having built five of them myself, and I know that a good K&B .40 will pull it along at a good clip, but nowhere near what your model is displaying in the video.

What size prop are you running on that Irvine .53. TIA

Status: offline 		I’m running a Top Flite 10 - 7 prop and the vertical is unlimited. I tried a lot of props until I settled on the 10 – 7. It is surprisingly fast considering the fairly thick Kaos wing. I started out with an OS 46 FX but it was not quite fully ballistic until I put the Irvine in it. I like the speed and vertical performance because it lets you stretch out the size of maneuvers and length of horizontal slow rolls. It is a fun little beast to fly for a 40 size!

Status: offline 		I have never owned an Irvine engine. I always intended to, but never got around to it, unfortunately. Way, way back, the Irvines were clones of the K&B line (internally), IIRC. Tower carried them for a while and offered pretty good deals on them.

Are you running a stock muffler? Or a boosted muffler such as the ones offered by Jett and Ultrathrust? I "think" Irvine may have offered boosting stock mufflers too, but I'm not expert in their line up.

Status: offline 		I’ve been using Irvine engines since about 1988 and at that time they were made in England. Started out with the silver case 46 ring engine and then two silver case 61s (one ring and one ABC) that use the small 39mm wide mount 61 case. Later on I bought a few of the red case 53s ABCs when they first came out. I got them for 40 size aircraft and it is interesting that they use the same bolt pattern and shaft length as the OS 46 FX. They are true ABC engines. The muffler has a removable internal baffle that I removed. I tached it when I was trying different props but I don’t remember the RPM with the 10 – 7 prop. The best I can remember is that it is turning up pretty good. No one that I know of is importing them anymore and I believe OS bought the company a couple of years ago and changed the carb. All my engines are pre-OS involvement.

New Irvine engines and parts are available directly from Just Engines in England http://www.justengines.unseen.org/acatalog/Irvine.html
