[RCSE] Off topic...Spar treatment for Sovereign from laser arts!

Building a Sovereign for one design and need a quick and simple
method for beefing up the spar to take a full yank up on the line,
anyone got a good carbon treatment without much deviation from the
kit components? Thanks in advance....kev

RE: [RCSE] Off topic...Spar treatment for Sovereign from laser arts!

Hi Kevin,
I too will be building a Sovereign from laser arts later this winter (gotta
get the bank...er wife to write the check first). At first I thought the
intent of one design was use the glider as it came out of the box to
eliminate any launching advantages from one plane over another.

On second thought, I just found
http://www.soarmd.org/BassNews/sovOneDesign.html and they allow any
structural changes as you describe so my initial thought was incorrect. I
haven't seen the wing yet, but can you apply the carbon and kevlar method
shown in the Majestic pages of the laser arts website?
http://members.aol.com/laserarts2/carbonwing.html I think they recommend it
for their 100" Scepter as well.

Stuart

Simply put, epoxy CF to spars and wrap sparbox with Kevlar thread
or Spectra (like "Spider Wire" fishing line). I think the supplied
thread is Dacron.

If allowed, you might also want to make the v-tail 45 degrees, and
extend the tips for better low-speed handling. Adding some washout
to reduce tip stalling probably wouldn't hurt either.
