Re: Kohler powered Q1
Martin Burns
John,
I have been at Sun'n Fun and on holiday, so I have only just seen your post. I am sure I can find a figure for the moment of inertia of my prop, but how do I go about checking that the mounting plate for the prop shaft is strong enough to withstand the gyroscopic loads? It is true that the CH25 engine I have develops maximum power at 3600 rpm in its standard configuration. In order to run it faster and get more power from it I have fitted EFI and purpose-made short inlet manifolds to increase the fuel supply and improve the breathing. I will be measuring static thrust in the next week or two to see if this has increased power over the standard carburettor configuration. Incidentally, at Sun'n Fun I checked out the Hirth F23 horizontally opposed 2 stroke, which they say has been recently redesigned. 50 hp with a belt redrive weighing only 5 lb, 84 lb total, oil injection and no need for a huge tuned exhaust. It looks very appealing for a Q1. Is anybody considering this one? Martin Burns Q1 G-BKSE Scotland ________________________________ From: Q-LIST@...

There is more to it than just RPM.. http://www.allstar.fiu.edu/AERO/BA-Background.htm <http://www.allstar.fiu.edu/AERO/BA-Background.htm> Do not forget to ensure that someone does the calcs for the gyroscopic loads. They can be big - how big? Big enough to be deliberately used in aeros to move the whole airframe. The kicker here is that the bigger the propeller the very much bigger the problem. Big pitch and yaw changes at high power can fail the crankshaft /prop adapter if it is not engineered correctly. This doesn't just happen during Aeros - taxiing at high power and turning on the brakes will induce high yaw rates, for example. The details are hazy now but I recall one case here in Aust where the difference between crankshaft failure and an acceptable service life was about 4" in the diameter of the propeller. Another point for you to consider, Martin. The engine you are proposing develops its peak power at 3600 RPM and Peak Torque at 2800 RPM. Direct drive looks pretty good at first glance. All else being equal, running the engine faster than 3600 RPM will give less power....I do not think that is the aim of the exercise.

Hi Tom

Glad to hear that your wing is salvageable. Had the skin delaminated? In what sort of condition was the skin? Any photographs would be interesting. The only similar problem of this nature that I can recall concerned a friend of mine who post cured his GU canard, mixing up Centigrade with Fahrenheit, and gave it a good cooking! I never saw it but he reported that it looked like a size 16 squeezed into a size 10, the skin bulging out all over the place, but held in by the shearwebs, spars and ribs etc. Regards Paul Buckley Cheshire England TriQ-200 Still buildingggggg.......

Hi everyone,
I have been getting complaints about my radio transmission for quite a while and I'm using the tail mounted foil antenna that is in the original plans. I just took out my NAV / COM and had it checked at the radio shop, and it checked out fine. Has any one tried the Morris DF Loop antenna? http://www.davemorris.com/dave/MorrisDFLoop.html Looks good on paper, and seems simple enough to install. I'm looking for some reports before I proceed. On the way to last years KS fly in I was denied entry into Cleaveland airspace because of un-readable radios.

Hi Mike,

It was I that experienced this problem (not Richard). Yes, I concur with all you've said. The switch to the NAV antenna was really just to confirm that the problem was not with the radio itself. That said, I did go flying in this configuration yesterday. Was about 50 miles away from home base and was able to talk to a buddy in the pattern. So, the repair job is not a priority - I cannot remember when I last used the VOR head... :-) Jon

Subject: Re: [Q-LIST] Mic problems Hi Richard, Let me take a stab at this based on what you wrote below... The Nav and Com antennas are quite similar frequency ranges so you can transmit into either one, but... typically the Com antenna is oriented vertically and the Nav is horizontal... So if you use the Nav for talking on you'll just be a bit weaker than on the Com antenna - but off the wing tip the Nav typically doesn't work for squat. That said, I think your Com antenna went TU as you stated. When the antenna is bad all the RF from your transmitter goes to the bad antenna and then bounces back to the radio which doesn't like that at all and many times just starts squealing like a stuck pig. Get an SWR meter from a HAM radio guy and check out your antenna. It measures how much energy goes into the antenna and how much gets reflected back. If you can't get that in wing antenna working again then go to the hardware store and buy some copper tubing and build one of these. I've been very happy with it mounted in the rear shell. http://mikedwyer.quickieairplanes.org/bent_c.html Fly Safe, Mike Q200 N3QP http://mikedwyer.quickieairplanes.org/ Jerry Marstall wrote: Thanks Richard, I'll check that out.------------------------------------ Quickie Builders Association WEB site http://www.quickiebuilders.org Yahoo!

Re: Wing repair suggestions appreciated

Hold the bus Paul,
these are not all viable options. The bubble in the glass is reported as "A greater-than -1-square-foot bubble, about 1/8th to 1/4 inch thick," Trying to press the glass back will not work, nor will injecting the bubble with micro - because the fibers are no longer correctly oriented. You may get partial tensile strength restoration but compressive strength has been destroyed. Even this approach may result in local overloads as the straight fibers surrounding the bubble try and take the load whilst the bubble is straightened out. The wing is already marginal strength-wise at normal loadings, at BL 50. John --- In Q-LIST@..., "Paul Buckley" <paulbuckley@...> wrote: removed and replaced by 'pour in' expanding foam.

Re: Wing repair suggestions appreciated
Larry Severson
All of Paul Buckley's comments are correct. I know from experience
because I bought a crashed plane with broken wings. I was also unfortunate enough to subsequently also crash (destroy) the plane. What was interesting was that NONE of the breaks in the new crash occurred in areas of my repairs (wings and tail). What I did was cut out the bad (separated glass), sand down the paint and bevel the still existing glass over a two inch area around the damaged area. I then exactly replaced the glass structure called for in the plans. The two inch overlap was more than double what is normally called for in such repairs, but I wanted a bit of insurance. It worked. I have saved the relevant broken structures for any interested party to view. Depending on the delamination, if the foam underneath is undamaged, drilling two small holes at opposite ends of the delamination will allow you to inject epoxy into one hole to fill the gap. Then use continuous pressure across the whole delamination to force the epoxy to attach the glass and foam while squeezing out the excess epoxy until the epoxy has cured. In this case, the wing will end up as if it had never been damaged. At 03:52 PM 4/28/2008, you wrote: Yes, that is correct.Larry Severson Fountain Valley, CA 92708 (714) 968-9852 larry2@...

Re: Wing repair suggestions appreciated
Thomas,
Sorry, your intentions were misread. Repairing the wing is absolutely possible as long as you follow the building manual for correct foam type, installation process and layup content of spars, precisely. You should also be a good glass man with competent people around the process, if not forget it. Bob F. helped me repair a severly damaged canard spar which is doccumented on this site. It now has 400 hundred hours since the repair and has been loaded to gross weight many times. So far we see no sign of problems. Having built the original wing, the job was realitively easy even with the tight working quarters (Made teh repair from both the top and bottom side of the canard under the passenger leg area). Further the canard got some good load testing while taxing around at gross which made me a little more comfortable before flying it. We decided to take this approach rather than building a new wing because the airplane was already flying and had been painted. My only point in favor of building or buying a new wing is your plane is not finished as I understand it and the task can be done rather easily. The upside is you will never have to worry when you are flying friends or family. If not you will probably always have it in the back of your mind when you do fast pull ups or get in the bumps fully loaded. In my opinion, there are too many other things that require your attention. Another option is to load test the wing in both directions after the repair is made but this can be dangerous as well. If you're not careful the load test can be more damaging than the benefit. If you would like to talk about this, plese give me a call at 510-468- 4891. I have experience in wing repair.

Re: Wing repair suggestions appreciated

Yes, that is correct.
toggle quoted messageShow quoted text
The repair was done from the underside of the wing, the damage foam removed and replaced by 'pour in' expanding foam. The expanding foam did not expand enough and left a void adjacent to the top skin, resulting in the wing collapsing. The correct way would have been to micro in a close fitting block of foam and repair the glasswork as per standard repair instructions. Although I do think that the best advice regarding damage to the primary structure would be to build a new one, let's not be too hasty....the damage may well be repairable. Is the glass skin visibly damaged due to the heat? If the glass has simply delaminated, have you considered injecting the void with micro? If the skin is actually raised, can you press it back to the correct contour, or has the underlying foam distorted with the heat? Have you done a tap test to find out the extent, if any, of the delamination? Paul Buckley Cheshire England

Many moons ago a Quickie dealer (name escapes me) had to make a repair to a broken wing. As I recall the story, he contacted QAC and they helped him with a repair scheme. It seemed to work, but some time later this person got in some heavy turbulence near a T-storm and the wing failed at the repair. Two lost. I think they were on their way to/from Sun 'n Fun. Maybe you could repair it by injecting two-part foam or micro, but I think I would replace the wing.

Obviously, if not repaired perfectly, this would be equivalent to an improperly repaired broken wing - but I have the impression that broken wings have been repaired successfully. I understand that the number of new plies should equal those replaced plus 1, etc., but I fear that this situation demands more than a good-enough-for-government-work approach. My question is - without replacing the entire wing from scratch - how to properly repair it? Perhaps there is a discussion of a well-tested repair somewhere in the Newsletters you can direct me to, or perhaps one of you have done it right, yourself. Thanks! Thomas L. Cline, N49X
