Although this is an old thread, I have been running AutoCAD on Windows 2000 with no problems, now I am trying to install it on Windows XP SP2. I am getting a compatibility error. Is there a way around this? I am going on an extended trip and need my drawings. Otherwise I will trash XP and...

I have finished 90% of the drawings for the flaperon controls, including the flap handle. I might even build a scale model.

Hi SparWeb: Yes, I was going to do that. I had hoped someone already had experience with it. I will have to look up on the Internet and run some examlpes of a life-cycle testing program. Thanks Tony

The parts are to be used in my Flaperon Mixer design. The Delrin will serve as bearings between two rotating tubes. Since the rotation is based on pilot contorl input, i.e., left or right bank, flaps up or down, there is very little rotational speeds, but might encounter some heavy loads...

About a month ago I asked for information on replacing nylon or Teflon with a more modern polymer product. It was suggested that I look at the properties of Dupont's Delrin. Since then I have had the oportunity to look at the spec data, and have come up with a few questions. The Delrin 570...

When fired into a flat plate, again there was very little if any difference in the amount of impact damage. Both birds shattered into a zillion pieces.

I saw the show and there was no difference in a frozen or thawed bird. They both did the same amount of damage. When fired into a flat plate, again there was very little if any difference in the amount of impact.

Interesting to say the least. I am off tomorrow and Friday (My Saturday and Sunday's) So I will have time to explore all of the above.

Thanks SparWeb: I did a Google search and came back with a lot of hits. I have bookmarked several for later reading. I have plans of visiting my home in Indianaplis later this year, so Toronto is not too far out of the way. Darn! There goes my cellphone camera idea. As for Murphy, I have...

I would like to add my 2 cents worth here. I too am not an engineer, far from it, but as a computer/network/WAN/LAN manager person, we found that communications cable with smooth surfaces was the worse to pull through fixtures, whereas cable with dimples/rough surfaces presented less of a...

Maybe some one can answer this question(s). My design calls for nylon bearings, fabricated to fit into 2" O.D. 4130 tubes. Since these involve very low speed rotations, but at times might call for excessive forces, is this a good material or should I use teflon? Is there another product...

I wrote to Mr. Heintz a month ago he is most likely very busy and has not responded so I will try De Havilland Canada, and or Murphy Aircraft since they're right down the road in Chilliwack, BC about 300 miles as the crow flies.

I was mostly joking about the patent. Too much of a hassle. I just want to get flying. No I have no intention of producing a kit. That too is a hassle, and the liability is not worth it. This has been my dream of many years and as stated, I have built designs of others. There are others...

I guess I must have misstated my intentions. I understand the flaperon design has been done before. In fact it was used on the Junkers Ju-87 in World War II. I have studied the other designs as found on the Murphy Rebel, Kitfox and the Zenithair CH701/801. My design incorporates ideas from...

Hi: I posted a thread in the AERODYNAMIC section seeking help on a flaperon design. I have not received a response, so I designed my own. I think it looks pretty slick, but looking slick does not mean very much in the air where it really counts. I am not a structural engineer, in fact I am...

Hi: Does anyone have any information on Flaperon Mixer controls, examples, documentation, etc. I sent an email to a certain person noted for his design, but he has not responded as yet. So I am asking if anyone out there can help. I have looked high and low for any information on the NASA...

Hi: THanks. I briefly checked out your site at work. I will look at it later when I am off. Tony

hI: I see there are several references to http://naca.larc.nasa.gov. Yesterday I went through the listing of reports, about 1/3 of them to get their titles. I did not find this one. Tony

Hi: Sorry for taking so long to respond to the above. I would like to thank you for your response. I will look into each. Tony

I lived in Lavonia, Michigan in the mid 80's and remember a helicopter pilot being knocked cold turkey when hit by a Canadian Goose traveling on the same flight path. Fortunately the pilot had the autopilot on and came too over Lake Erie, or was it the Detroit River? Anyway, there was a lot of...
