  The Dynon heated Pitot/AOA probe that I have must  be different than yours, as the new heated ones have about 1/8 inch thickness of  nickel steel where the screws go into, and drilling / tapping them was  not an issue. The plumbing and wires are in the center where they aren't likely  to be hit with the drill going in, although I would certainly watch my depth  while drilling, as it states in the instructions.

 Chris,  I'm going the same route, except I was foolish enough to put it where  Van's
 probe went. The aileron push tube is a problem there but manageable.  Fortunately,
 I was warned, so I'll pass it on. The Dynon tube's metal - where  you screw
 it to the Gretz mount - is very soft and thin. Drilling is not too  bad but
 tapping the holes for screws must be done very  carefully.

 [quote=" I installed the new Dynon heated pitot /  AOA probe,  which is fabricated
 from nickel and it looks like a real  quality unit. I plan on  at least one
 Dynon box, which will give me  visual and aural AOA / stall warning.  The probe
 also is temperature  controlled for low current draw, and has fault  annunciation
 on a Dynon  box, or a stand alone LED if not using a Dynon box. My  experience
 with  the Dynon system I  have in the RV8 couldn't be better. The  system  is
 rock solid, and loaded with features.

				Chris,
 I guess I didn't make it clear. Mine is just like yours. Drilling was a minor issue but tapping must be done very carefully because the metal is so soft.

				Hi guys, I have the same pitot.  Could you please tell me what size
 drill and tap you used for your pitot in order to enable mounting to the
 Gretz mount.
 
 Many thanks in anticipation.

 Patrick,
 I'll have to check my notes but I think I drilled it out to a #6 screw. Got stainless steel ones from Aircraft Spruce.

				Thanks John, I'd appreciate the drill and tap size when you get a chance
 - no hurry.
 
 Wishing you a safe and happy new year mate.
 
 Regards
 
 Pat

				I suggest the "Aircraft Maintenance Handbook". All the stuff you ever wanted
 to know and then some. One of the books on the original book list for my A&P
 license. Mine is at the hangar or I would find the size for you
