If you remember when one of the boys from the A/V dept brought the projector to class and set it up to run, you'll love this.

Rick,



 Thanks for that video post. My Firestar does not have the aerodynamic wing strut fiberglass shell installed. This will be one of the first things I do before I fly it.



Thanks

Dennis 



 Good   !

Richard , I am amazed at how much difference there is , I built my KXP with streamlined wing struts but didnt realize how munch difference it mad ! Thanks for that link and I think there is more to learn on that same Youtube page

Chris D/Gang:



1987, I was flying my brand new FS without brakes and with standard round 

lift struts out of Gantt IAP, all 600 feet of it.



I finally saved up enough money to buy 4130 streamlined tubing for new lift 

struts.  Brother Jim welded them up for me, I got them prepped, painted, and 

installed.



On my first test flight I was amazed at how stable and solid the FS felt. 

The round aluminum struts were constantly dancing in flight.  On my first 

landing I had to go around.  I ran out of airstrip.  With no brakes to slow 

me down, and a hefty increase in glide and reduction in drag, I had to 

rethink my landings.  Was time for brakes.  ;-(  By Spring 1988, I had 

brakes and longer heat treated 4130 gear legs, 35.5" long.  I chose that 

length because Lindberg Heat Treating in Orlando, FL, could only go 36".  By 

being able to get the nose higher during landing and roll out I was able to 

use the bottom of the wing to help slow me down, plus my new Hegar Brakes.

John- Very interesting info about your Firestar.  I have a set of steel (!) streamlined struts, almost 10 pounds for the pair.  I intended to swap them out for round aluminum to cut some weight.  Once they are off, I will probably put them up for grabs.  Your comment about your 600 foot field got my attention.  My spot for a field at my place in Vt. is about 600 to 700 feet long.  It's on top of a small hill, with the ground being lower at both ends.  The prevailing wind is aligned with the runway.  I was wondering about the necessity of brakes, and now I know.  I wonder if Richard Pike still has the old FS brakes he mentioned.

Bill S/Gang:



I think the reduction in drag, absence of vibration, and good solid feel of 

the steel streamlined struts will far outweigh the difference in weight, 

which probably will not be that much.  Definitely not progressing going 

round aluminum.

The experiment we saw on the video and many others are explained in the book "Shape and Flow, the Fluid Dynamics of Drag" by Ascher H. Shapiro, published by Doubleday Anchor.  It's out of print but I got a copy via the internet.
