Guys. . .a very lively discussion in presently going on in RC Groups
about installing a Rotary Driver System (no external wing hardware) in
moldies. Those of you who have those might want to get into the act.
The pertinent link is
http://www.rcgroups.com/forums/showthread.php?t=775640&page=13. There
are presently over 185 posts including some by JW and Mark Drela.My
initial contribution is in Post 66 on page 5. Some others with
mechanical engineering expertise are doing their own R & D to contribute
their finding
My own contribution to RDS development started about 20 years ago.
Subsequently there were articles on the concept published in the
September, 1993 issues of Model Aviation and RCSD. In my website at
http://genie.rchomepage.com I have a lot of RDS material in File 6, but
I consider the RDS surface only scratched. More thinking needs to be
done on it to maximize its potential and ease of installation..
This morning I did a drawing now viewable in Post #186 on page13 that
offers some ideas for pre-fabbed and more refined RDS parts that would
require some precision machining. What I illustrate is certainly doable
and may be of interest to look over.
It's been a long road to get the RDS into broader use, largely stymied
by the advent of moldies with pre-made wells to accommodate traditional
hardware. However, I hear some of the Europeans, who compete at high
level, are custom installing their own RDS versions in the molding
process without even having any well covers. It's very good news to hear
that RDS systems to assure nothing hanging out of the wings are being
now employed in high end airframes.
One of the things about RDS that I find very intriguing and that I use
in my Genie line of sailplanes, is that in 3-piece wings, no wells,
servo mounts, servos, leads, connectors or well covers, as well as
horns, clevises, pushrods, etc. are needed in the tip sections. This
simplifies tip construction and moves mass closer in for better response
in the roll axis.I get into this in File 3 of my website.
In any event, you may find that RC Groups link to provide some
interesting reading and hopefully, have something to contribute to the
discussion.
