I haven't flown mine yet, but it is now covered and just needs the
motorstick... I did a rolled tube for the MS, and that should come in
around 1g, and the prop should be about the same... the fuse, wing,
and tail covered came in under 4g, so the all up weight should be
under the 6.2g minimum for No-Cal... Is yours just not able to stay
in the air, or what is the problem...? 1/8" rubber might be a bit
big, as .100 or thereabouts seemed to be right for me with a 6.2g Fike
when I was flying that... I should be done with this thing in a few
more days, and can post what I found after a few test flights... For
the size of this No-Cal, 6.2g is pretty floppy though...
I'm sort of guessing that 12g + 1/8" rubber might be a bit much...
probably would be fine for outdoor, but indoors might be a bit fast...
