I have the Mistral intake, but like was stated, I am not flying yet.  It is
a pretty unit.  Hope to be trying to start the dang engine thingamajig
hanging on the back of my Velo pretty soon (yeah, I have been hopin' for a
while).  I am well into wiring the duel alt/duel battery scheme, Z-14 in the
Aeroconection book.  ECU wired, batteries, alt, contactors, regulator etc
installed.  Now to get all the wires to play nice behind the panel

You can check out pictures of the intake on my website at

We considered trying to build the intake, (even fabricated a very heavy
model) but figured that with our limited skill set and the PITA factor of
trial and error and the associated cost we would likely come out a head just
buying the intake.  Good luck.

All the best,

Chris
