Re: Modern Pitot on '48 Ragwing

Yes, I understand. Of course, the pitot tube is normally aligned with the chord of the wing, presumably for accuracy at cruise.... since the angle of incidence is important for accuracy. It’s doubtful that a minor change in the 170 pitot such as You’ve likely done would be significant. 
The later “L” type Pitot heads have drain holes incorporated in them, but that pitot is not a mod I’d do on my airplane.
(The actual location of the drain is not exactly / accurately illustrated in the depiction below nor are the heating elements.... this is only a teaching-tool I’ve plagiarized.)
By the way... if anyone DOES perform this modification, Note that the pitot head is relocated INBOARD of the wing strut. This prevents someone walking into it and being injured.
