I plan to have a full grille block on my 1993 Civic, but will have an area that opens once the engine fan turns on.
I would think it pretty straight forward to make work.
I'm guessing that i could use the electrical signal that turns on the fan to also open the door on the grille block.
Once the engine cools and the fan goes off, the loss of the signal would make the door snap shut again.

I was into R/C planes as a kid, but was poor, so I never actually had one.
I remember little motors used in R/C planes that are called servos.

Could a servo be used for this ?

The idea is inspired by what 'AndrewJ'.did with his car decades ago.
His design turned on a light and alerted him to pull a cable controlled door in the grille.
Brilliant and simple, but I'd like too see if I could make it be controlled by a motor instead.
