I intend to install the Dynon pitot mast as a retrofit in my RV8. It will replace the standard vans single line pitot system already installed. The mechanical installation of the mast support shouldn't be as difficult as I initially thought. I will position it against the outboard side of the rib that is located immediately outboard of the aileron bellcrank. Unless there is a way to incorporate the existing pitot line (I don't see how) I will run new plastic tubing for both the pitot and static connections. Checking to see if anyone has done this same retrofit and willing to offer suggestions. Thanks.
