[NSRCA-discussion] WOW - Brio maiden

[Keith Black]

Excellent! Congrats Kelly.

On my Brio I initially felt it didn't need any mix for knife edge flight
(first flights were in the windy spring). Once I got a calmer days to fly I
decided it needed just a bit (about 5%) up elevator on knife edge, but still
no aileron correction. After quite a bit more flying I finally ended up with
17% up elevator mix on right knife edge (holding left rudder) and 6% left
aileron mix (yes, left aileron as it has slight adverse roll on right knife
edge).  For left knife edge I have 6% up elevator mix and no aileron mix.

The surprise is that I had to go all the way to 17% up mix (in JR 10X terms)
to keep a straight line on right knife edge, but considering how little
elevator it takes to keep the nose up in knife edge this actually equates to
a minuscule amount of up elevator.

My Brio is electric so I have a bigger column of air passing over the plane
with a 20 to 22 inch prop, this will probably cause it to behave somewhat
differently than your glow version.
