Hi Stan
This is pretty much how I did mine see www.peterskr2s.co.uk. Haven't flown
it yet so I can't tell you whether it made any difference!

Keep in mind that you can't eliminate induced drag...you will always have
wingtip vortices. I can't write the formula on my tablet. (cl squared /
pi e AR). Most wingtip devices simply improve the efficiency by increasing
the effective span or increasing the elliptical ratio since that's about

Stan,
I did that mod after flying the plane for 4 years with the standard tips. When
I added the tips, I also cut 8? off of each wing. I don?t know if it made any
speed difference (too many mods at the same time), but it certainly changed the
way it lands. It is extremely heavy for a Sonerai I
Wingtips that hold fuel provide wing spar loading relief. You should be
able to increase the max gross pound for pound...maybe even more if you
burn out of the wingtips last.
