Freddy,
Thanks for the Arnold video. Found it really inspiring, to the point I am now
reading
Hoerner's book on drag reduction.
I will not go crazy with this project but I am planning on leaving my Europa
light
and ugly at the beginning to be able to experiment with it a little.
And no, I don't think I will have the patience to profile the wings down to
.003"
as Arnold did in the AR5. Impressive!!!
I have so far not modified anything important in the interest of weight
reduction
(except for the cockpit module lower corner longitudinal straps which required
100 pounds of epoxy to fill the gap to the fuselage shell so they were
appropriately
modified to make them fit better). I think that eventually I want to
play a little with the cowling (just can't stand the way the doghouse looks
in such a neat curvy plane), cooling drag and interference drag between the
wings
and fuselage (and the usual gap sealing stuff). I know some people have done
a lot of work on those areas so the reading will be fun.
I really want to see what can be done weight wise. Although I have not weighted
it all together, the components feel heavy. The wings in particular! I just
added
the aileron mass balances and OMG! (Although I think a lot of that weight
will come off when I paint and adjust, still).
Anyway, thanks for the reference on the video.
Regards,
Chris
