Dumb Question by
JohnO

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...

parking lot on...

What is LEAF? by
TM
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

find them labeled AN960-10 (in the LEAF catalog, for...

Nick

flight than for hovering? If so, anyone know any figures for say an

old days by
Airman
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

respond.

Building a Gyrobee by
TM
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...
