Valin,
You may have already looked into this, and I am not at all familiar
with the VPX, but if the VPX has flap control functionality, perhaps
it already incorporates shorting the flap motor for braking ?

Good questions. I've dropped Marc a note
to inquire into the flap motor output
characteristics . . .

Thanks Bob N and Jeff Page for pointing this out . This detail isn't in the VPX Installation Manual and I assumed, maybe incorrectly, that the flap motor power lines just went dead to stop the flap motor. The manual does specially say that the VPX doesn't work with the Lancair flap circuitry because it uses limit switches to stop the flaps rather than the position sensor. So Marc may have thought of how to work around the VPX flap commanding and polarity changes vs. the Lancair Legacy's flap circuitry with motor braking but rejected it because he didn't think the position sensor could sync closely enough with the limit switches...
Thanks for asking Marc A at VPX for the specifics!
