RE: [RCSE] motorcycles
I haven't dropped the R60 in many years, so the yearly thing may not be true. But the midset of being mentally prepared to drop the bike (or to have a mishap) every time you ride is good defensive riding, IMO. It ain't like a car where you simply hop in and go somewhere. Truth is, I've not ridden my R60 since I moved to Jasper 10 years ago-- it was "in storge" for 5 years, and I've been planning to get "tires and a battery" for the last 5 years. Finally did this year and when I get time to put the tires on and check over the bike, I'll start riding again. Cautiously, until I get my "sea legs" back, then I'll start making longer trips. --Bill >From: "Gavin Botha" <[EMAIL PROTECTED]> >To: "Dennis Phelan" <[EMAIL PROTECTED]>, <[EMAIL PROTECTED]> >Subject: RE: [RCSE] motorcycles >Date: Wed, 23 May 2001 08:16:21 -0700 > >I have been riding bikes continously for over 30 yrs., and have competed in >everything from off-road Trials to 750cc Superbike and F1 Racing.

Re: [RCSE] Celebs in RC Soaring
Nifty website. It amazes me how realistic the special effects have become over the past few years, much better than the "model-on-a-string" effect of years ago. I'm curious... how were the Harrier scenes done in _True Lies_? I assume that they really didn't have Ahrnohld flying a plane in downtown Miami. --Bill >From: [EMAIL PROTECTED] >To: [EMAIL PROTECTED] >CC: [EMAIL PROTECTED] >Subject: Re: [RCSE] Celebs in RC Soaring >Date: Wed, 23 May 2001 10:37:45 EDT > >Pat, >Thanks for the kind words, but my work can hardly qualify me as a >celebrity. >My team and I are just a few of the thousand or so individuals who bring a >movie to the big screen.

I have heard his name mentioned several times on the TechTV channel, most recently, last night. Jef was one of the principle developers of the early Macintosh computers. He was one of the first proponents of slope aerobatic competition and an early developer of cheap, expendable slope models. Anyone remember his fight with RCM over a product review of his cardbard slope model? As I remember, they gave his kit a very negative review without even flying it.

Re: [RCSE] why are ailerons top-hinged?
Arne, they certainly look better, since nothing is much uglier than a control horn sticking up. Another reason is that to get enough up deflection, the gap would have to be very large if bottom-hinged and create unwanted turbulance. If top-hinged, very little gap is needed to allow down deflection. I think you are a prime candidate for eliminating any control horn, backplate, clevises, keepers, output arm, threaded rod, exit guide, etc. by using the all-internal, Rotary Driver System to operate the ailerons. See http://www.proptwisters.org/rds2/ for details. See the SOURCES page. I have a supply of the couplers on hand. -- > From: Arne Ansper <[EMAIL PROTECTED]> > To: [EMAIL PROTECTED] > Subject: [RCSE] why are ailerons top-hinged? > Date: Wednesday, May 23, 2001 8:06 AM > > > hi! > > simple question: why are ailerons top-hinged? i have two explanations: > > 1) they look better this way > > 2) since the pushrod is usually on the lower side of wing one can use > shorter control horn (by the thickness of the aileron), to achieve same > throw that helps to reduce drag somewhat. > > since i'm putting the pushrod on the top of the wing i would like to put > the hinge to the lower surface. are there any aerodynamical consideration > which make the top hinged ailerons with continous upper surface more > desireable? > > arne > > > RCSE-List facilities provided by Model Airplane News.

Re: [RCSE] why are ailerons top-hinged?
It's usually because ailerons have more upward deflection than downward, especially in a crow or spoileron setup. Having the hinge on top allows for this larger movement with a smaller cutout (gap) in the wing. That's why flaps are usually bottom hinged...greater deflection downward. It all becomes academic with wipers however, since the hinge is pretty free to move sans-gap up to about 60 degrees (in most cases).

I have been riding bikes continously for over 30 yrs., and have competed in everything from off-road Trials to 750cc Superbike and F1 Racing.

Re: [RCSE] motorcycles
I only fell once with my motorcycle many years...but I was traveling at 75mph. A safer sport/activity may be slope soaring with a lead sled in big winds...a real rush, like motorcycles, but it's the plane that hits the ground, not you. E.

[RCSE] why are ailerons top-hinged?
hi! simple question: why are ailerons top-hinged? i have two explanations: 1) they look better this way 2) since the pushrod is usually on the lower side of wing one can use shorter control horn (by the thickness of the aileron), to achieve same throw that helps to reduce drag somewhat. since i'm putting the pushrod on the top of the wing i would like to put the hinge to the lower surface. are there any aerodynamical consideration which make the top hinged ailerons with continous upper surface more desireable? arne RCSE-List facilities provided by Model Airplane News.

[RCSE] Understanding Polars without math.
Years ago I read the book "Understanding Polars without Math". Let me whole heartedly recommend this book. It's a wealth of information and really doesn't require any math. None believe it or not. The book answered some questions and shed quite a bit of light on airfoils and reading polars. Very useful.

[RCSE] How do you read a polar?
Hello everyone, I went to the selig website to look up some airfoils and the polars are completely greek to me. How do you interpret the data? Is there any website that explains how to read a polar. I am not an aeronautical engineer so I need a practical explanation if possible. I have seen a book called understanding polars without math. Anybody read it? I would really like to learn what makes some airfoils are better than others, and make an informative decision on which airfoil to choose rather than what everbody else uses. Currently, my TD airfoil of choice is the SD7075. I prefer it to the SD7037 as it seems to have a bit more range, responds to camber well and will still slow down almost as slow as the SD7037 when thermaling. This decision is based solely on my flying style and personal experience and I am sure others will dissagree with me. I would however love to learn why one airfoil suits my flying style than another?

I have worked everyday since JAN 3 except Easter and Mother's day. I am now ready to start training for the F3J finals and am desperately looking forward to some model and full-size glider flying.
