Dual NACA Vent Valve

Well Known Member
so with my uncontrolled adhd and to kind of help me along in my effort of getting back into building my rv10. i decided to model my own dual naca vent valve assembly.

ive printed it with PA12-GF with ABS as support interface. All the hardware has been easily accessible to get from the jungles of Brazil thanks to Uncle Jeff B.

my next step is to work on designing a PCB to go from 14v to 6.8v and have some stoppers to limit the swing of the servo.

Very nice!

If I may give you a suggestion.. use springs on the servo pushrods. By doing that you wont have the servo hunting (servo buzzing) for a precise position on fully opened or closed positions.

Something like this:

If you are using a digital servo it will likely always be buzzing because of its precision. I used linear servos they have plenty of torque and the positioning is very stable. so it stops drawing current almost completely once it reaches the position.
