All
Attached is the EAA Tech response- very encouraging. My take is,
install the VGs before Phase I testing and you're OK. Archive this with
5 stars-
Hi Bill,
As a matter of fact, anything that is fixed and does not require any
input from the pilot that is used to reduce the stall speed of an
aircraft will not jeopardize the LSA status of the aircraft . VG's,
fixed slats, dimple tape that is affixed to the airfoil, and any other
fixed, non-deployable aid can be used. Whether these aids actually work
or not is determined during Phase 1 testing. If they do not result in a
stall speed of 45 knots (52 mph) or lower, then the aircraft is not LSA
compliant. The key factor is pilot input, which is why extending flaps
is not allowed to meet the stall speed criteria - the pilot must do
something to make the flaps extend, which adds to the pilot's workload
during a critical phase of flight. If you have any further questions,
please contact me.
Cheers!
Tim

Subject: Vortex Generator
EAA-
Once again, the question of whether vortex generators can be
installed on a Zenith 601HDS wing to ensure LSA compliant stall speed
has come up on the Matronics list. Can VGs be installed prior to
Phase I flight testing to enhance the probability of legally meeting LSA
stall performance limitations?
Thanks.

There's LOT's of gauges available that will work, go to
www.summitracing.com
look up fuel gauge, and there is a gauge selector menu
just make sure that the ohm's range matched your senders.
