If you can make do with a 3" diameter valve look at Eric Jones' idea. We
have the prototype installed in our ES but have not flown yet. It is
actuated by an RC servo and a controller that mounts in the panel. Works
great in ground testing. It can be varied between full open to full closed;
is very light weight and smooth.

I am using a 4 inch diameter duct from the tail plenum in my L-IVP to cool my A/C condenser and would like to include a selonoid operated shut-off to reduce the drag of the plenum air while in flight.
In my original design, I used a divertor box from a clothes drier exhaust; which proved to be too light weight so I am looking for something a little heavier. Anyone have any ideas or suggestions????
