Any Q is faster if it
is lighter and more power is added. Those factors are
probably more important than the airfoil.
VG’s on the GU solve
the rain/contamination problem, but are a pain when
trying to keep the canard clean.
LS-1’s break too, but
just outboard of the fuselage instead of farther out
on the wing.
There are several GU’s
flying with O-200’s on them, so I suspect the QAC
change from GU to LS1 was driven more by contamination
problems than by strength issues (despite what was
said in the QAC newsletters).
I am not sure that the
speed of GU vs LS1 has ever been fully resolved, but
there are a lot of fast GU Q’s that have been built
with a variety of engines (Corbin’s is a very fast
Q200 and has a GU canard. Paul Spackman’s Q2 with the
GU and Jabiru engine is/was also very fast). More
LS1’s have been built because of supply, so the sample
size is larger and probably more is known about them
because of that.
……The GU will not
explode if hit by lightning, since no carbon fiber.

In my opinion... 1)
the GU spar ends 4 feet from the wing tip. Lots of
them break there on a hard landing. 2) It wasn't
designed to carry an 0-200A (but I don't know what
your running for an engine). 3) if you never fly in
the rain your ok. And I challenge that the GU is
faster? The fastest Q out there is Sam and he's an

faster, and my LS one is already a little
damaged. Plus I'm doing some fairly major
changes and replacing my firewall already so
seems a good time. Faster is legit the only
reason for me wanting the swap. But I'm open to
hearing reasons not to change back and to keep

Located 40 minutes from Salt Lake City
curious why you would switch
I read indicates the LS is some
or there have a decent GU canard
sitting around for a Q2? Tossing
around the idea of swapping my
LS1 back to that. Not fully
decided as of yet but if there's
one laying around for the right
price that would save me making
a new one it might twist my
