RE: World Models Mach II Wing Failure?
I have an NIB MachII in the garage, and the wood has horizontal grain and definitely doesn't look like Balsa. I'd suggest you do some post mortem and see if you actually have enough glue around the thing.

RE: Good pattern plane for saito 91
I think the TaiJi might be discontinued. AT least I could not find it in their latest WM catalog. I saw the Groovy 90 at my LHS, and it looks much nicer than the TaiJi. The catalog lists it weight as about 8 lbs. It comes with plug in wings and stabs, both have adjustable incidence. It also comes with a fancy swept back CF landing gear and anti-vibration engine mount. So far, all I see is that WM recommends only 90 size 4 stroke for this plane. BTW, the 6.74 lb CA lists for the Widebody 60 was a bit misleading; their website says the 60 was tested with with a 60 size 2 stroke engine. Put a 4 stroke on there, and you will most likey get to 8 lbs. I think it's a push weight-wise.

Just two days ago, I was running a G51 at 11700 with a 11x7 and a GS45 ABC at 14700 on 11x5 on 10% coolpower. Both are Italian engines. The G51 was used, but the GS45 was new. I got both at a local swap meet. Temp was 60 F and at sea level.

I have a pair on my old Tracer. They are OK; I've never had any problems with them. But again, I fly off hard surface and Tracer's calls for short stubby struts. If you fly off grass (or worse) or the plane requires high ground clearance, then they may be a problem for you.

RE: Ears
[quote]ORIGINAL: compute42 Most RC engines arn't gonna seriously effect your hearing, starting etc... A screaming Wide open throttle 2-stroke a couple of feet from you will. Be respectfull to fellow modlers, if you are adjusting your high speed needle for more than say 30 seconds, do it somewhere else than right in the pitts. Short bursts of medium/high volume are ok, but for a duration it's damaging. I'm an Audio Engineer by trade, and clients buy my ears, I seriously value them, but don't use earplugs when I'm flying unless I'm adjusting the high speed needle, or breaking in a new engine. My .02 ~Andrew [/quote] I quite disagree. I had my hearing tested a couple years back, and I found out, to my surprise, I had slight midrange hearing loss in both ears. The audiologist looked at my chart and kept asking me if I had been exposed to either very loud gunshot noise or constant low level backround noise for extended periods of time. It turned out to be the latter from noises in the cockpit. According to her, there is no real minimum threshhold for hearing loss. I've always wear noise canceling headsets while flying and I still suffered hearing loss. People generall don't think twice when reaching for eye protection, but hearing is just like eyesight; once you lose it, you will never get it back.

RE: magnetic actuator question
[quote]ORIGINAL: jonathan8388 do you need a certain kind of radio to power the magnetic actuators, or could you use any kind of radio for them? [/quote] The short answer is: you can't use any current crop of commercial crop of receivers with them. All the receiver and interface electronics are custom made to a specific application. The coil's magnetic moment, as you may already know, depends on number of turns of wire, current flow, and cross section area of the coil. So amount of deflection is controlled by DC current flowing through the coil. You will need to build the interface circuitry between the receiver and actuators to translate the receiver signals to a DC current proportional to the stick movements, should you choose to use a commercial receiver. There has been lots of talks on microflight circle to convert the electronics of those Microsizer cars to a flying model, as those cars actually use actuators for controls, but are are lots of pitfalls. Most guys I know of who are into this kind of stuffs tend to have pretty extensive formal technical backgrounds; it's out of the leagues of most average RC modelers. One of my projects for the next winter (or two, or three) is to build a flying insect, sort of a rc version of a rubber powered insect flying machine Paul McCready built quite a few years ago.

Superstick has a relatively thick airfoil and high drag. If you want something that slices through the air, get an Avistar with a big spinner in front. The cg stated in the manual was too far forward. Adjust it between 3.5 and 3.9 inch to suit your taste from leading edge of the wing and max out your controls throws.

RE: Engine Temperature

[/quote] Someone published an article on 4 stroke engines in one of the latest issues of the RC rags( I can't remember which one at the moment) . In the article, the author measured the exhaust temp with an EGT probe of various popular 4 stroke engines with various configurations and fuels, and the numbers tend to be around 500-550F. I found it rather interesting that the author compared EGT reading for castor and synthetic on the same engine with same settings and found the engine actually ran slightly cooler with syn fuel.

RE: performance of a Kaos
[quote]ORIGINAL: MHester Well, I don't consider myself an "expert", but I do have a little experience with design and competing. Personally I love the UFO, it's the plane that got me interested in pattern in the first place. I remember getting that Tower Catalog and there was Joe, pencil thin mustache, sunglasses, holding his "new" UFO. I almost had a cow I wanted it so bad. I hate to let this one go, because it was Joe's personal plane, and it's autographed....and the freakin electric retracts still work! But I realize that because of what it is, I'll never fly it, and it's gathering dust in my shop. I did see it fly once, and it was a rocket! I loved it, but it was a missle and it's also very heavy. But compared to the Kaos, it's apples and oranges. It's just a better plane. The Great Escape was even better, I had one of those too. If Joe was designing current 2 meter planes I'd have one (and yes I know about the 2 meter birdy, but it's just a big dirty birdy). Personally I love planes from that era like the Curare and the Tiporare etc, but you have to fly them like they were meant to be flown, fast and screaming. They ARE dated designs, but I like them a lot. I just don't care for the flying box look of the Kaos, it's just before my time I guess. And it doesn't fly good enough to stand out in any way to make it anything special. So, it's just not for me. And it's not great enough to recommend it for someone else looking for a plane to do what the original poster was wanting to do with it. There are better planes out there. I still say the Widebody 60 is the best plane of it's size, flying wise, out there today. It just totally kicks butt, and it IS something above and beyond. THAT plane I could recommend easily (and have a million times I think). To each his own, to me a Kaos is just a flying box...stick...something. -Mike [/quote] So, in your opinion, what important technical features and/or rule changes in the past few years makes a 2m plane of modern design "modern"? So far, all I read is that you don't like this or that because you "don't like them".

RE: Epoxy vs. Aliphatic Glue
Aliphatic glues have been around for a LONG time. It's been used to glue everything from violin to bamboo rods to furnitures. However, you need to know how to use them properly. Modern Ali glue like titeBond needs to have a very tight fitting joint and very thin layer of glue for it to reach it max strength. in fact, the thinner the glue joint, the stronger it is. If the joint isn't tight-fitting, the glue will never reach full strength. The alternative is to use poly glue, where it actually expands to fill the joint, so the joint need not to be as tight. Poly glue is probably the strongest general purpose glue you can buy right now. It has a long working time and reasonable curing time, and it is easier to use than epoxy.

RE: How often do you crash?
I have never crashed in terms of a totally destroyed airframe. I still have every plane I've built and/or assembled, including the original PT-40 trainer that's now hanging in my rafters. The most serious mishaps I've had was a ripped out landing gear from a stick because someone else was on the runway while I was tring to land. I steered away from the guy and just dumped the plane in a field and the gear ripped out from that incident. Some 5 minute epoxy and 24 hour cure time and it was back in the air. OTOH, the Avistar I've assembled for a local club as a club trainer has seen lots of carnage (and students too!). I think someone else mentioned that you should plan you flight and do a pre and post flight checklist rather than just go out and punch holes in the sky. It's good advice and it works too. P.S. Get off the flight line and put on your hard hat when the T34 racing guys take to the air. Those guys redefines the word 'carnage'.
