REFLECTOR: NACA Air Intake and rain/water?

[Scott Derrick]

I also cover my plane away from home. Reduces the water intake 
substantially.

>> Hi All,
>> I wanted to see if anyone had any issues with their Top NACA scoop air
>> intake with rain or water getting in the draining down to the throttle
>> body.
>> I have not flown in rain but expect I'll it'll happen and was looking
>> this setup and it looks like water could just run down the intake and
>> into the throttle body.
>> Also, if the plane was outside when it rained looked like this could
>> happen also.
>> I was wonder what other have done in this area or thoughts.
