Earlier this week I had the tail feathers bolted in their final position and then removed them for storage. While they were on I threw on the EMP fairing just to get an idea how close it would be and as I expected I’ve got quite a bit of work to do on it.

So since I’ll be doing major plastic surgery on it, I was thinking about adding a ram air inlet similar to this one on Tim’s site.

But then the thought crossed my mind…. What about water?

What’s the secret to keeping water out of the scat tubing? Rain on the ramp, in flight, or just flying in wet clouds could pile up some water pretty quickly.

I dunno what Tim used but on the Mooney I used to own that had an inlet in the roof (later models moved it to the empennage fairing) and used a 1/4 ID diameter rubber hose that drained via a fitting out the bottom of the fuselage.

My overhead console will get it's air from a NACA scoop on the right
side. The only way to keep the water out is to force it to run uphill.
And this may not be sufficient if you have heavy rain coupled with the
airflow through the OC ......

You could open a small hole in the scat tubing at a low spot and have it
drain somewhere in the aft fuselage ...... but I personally don't like
that idea.

The thought does cause me to ask ..... anyone seen indications that
water gets into the tailcone from sitting outside in the rain??? Is
there a need for drain holes in the fuselage at the lowest point .... as
it sits on the ramp???

On the RV-4 the plans call for a 1/4" drain holes in the bottom skin at the
lowest point just in front of the last few aft bulkheads to drain any water
that manages to get inside. With the tri-gears different ground attitude
the locations would need to be adjusted but the concept is prudent in my
mind.

Phil,

I install a drain tube that runs from the inlet area down to the bottom of the fuselage where I installed drain fitting of sort that lets the moisture exit the plane.

If you would want any photos of what I did, let me know.
