When designing rotor systems, you have to keep the tip speed subsonic to prevent all sorts of problems and losses that would otherwise occur at the sound barrier, right? What about large turbofan engines such as on modern airliners? The fan tips must be travelling at many orders of magnitude...

Hi, Can someone point me to any official accident statistics that would demonstrate the relative accident rates of various classes of certified and experimental helos? Specifically I would want to exclude any accidents that were pilot error or failure of maintenance. and only consider accidents...

Greetings from Edmonton, Alberta Canada. Where it is a balmy -8 degrees Celsius. Best wishes to all.

I have 16 Bell 206's for sale. If you are a former Viet Nam helicopter pilot, this may be your chance to own your own bird. I was in BUF's out of Kadena in 1968. Website is boblewis.net/helicopters. Take a look! -Bob-

Has anyone seen, or read about, that Skycycle? http://www.thebutterflyllc.com/sscycle/gallery.htm http://javimoya.com/blog/youtube_en.php http://www.thebutterflyllc.com/sscycle/images/002.jpg

I've heard talk of new rules in '07 which will affect the lightweight gyro's which currently require no license. Can anyone comment on this? I absolutely will get gyro traing before I fly (I'm also a motorcyclist who learned to ride in 1978 by making two circles around the dealer's parking lot on...

A newbie question, no doubt, but I need to know. This is a quote from a GyroBee builder's site: «There is some variation in the labeling of standard 3/16 aircraft washers. Primarily, I have labeled them an AN960-316 but you will also find them labeled AN960-10 (in the LEAF catalog, for...

Is it true that a helicopter requires less power for slow straight and level flight than for hovering? If so, anyone know any figures for say an R22?......or even hazard a guess? Cheers

Hello, what are the control inputs required in a hover in an ideal situation, what I am trying to figure out is what are you doing in a no-wind situation to hover. I have read several articles and books about helicopter flying and I am still a little confused as to what you have to do, from what I...

I sure miss the old days when we had a lively discussion group with some very experienced pilots opining upon matters. Poster were for the most part civil and if you could ask the right questions then listen a guy like Nick Lappos (or many other very experienced pilots) would respond. Happy...

A little site I created http://www.webspawner.com/users/hwww/helipadheliport.html

Greetings, all. I am new to this group, but I have been studying Gyros for a few years. I've decided on building a Gyrobee. I'd love to build one from scratch, doing my own cutting and drilling, not for the cost savings but just because I'm an engineer at heart and love to build things. The only...

Hi all, I found an interesting article about the differences and similarities of the two birds on the internet concerning which makes a better training and I thought I would share; enjoy. http://www.flymidwest.com/SchweizervsRobinson.pdf

First day of the new year and I find this little link in a cooking newsgroup. Go figure. http://www.jet-man.com/actuel.html Then there is his homepage showing some of the other things he has put these model jet engines on.
