OK, finally can tell everybody that the correct standoff size needed for the DA 50 and the Eagle is 2 3/4". The supplied standoffs with my DA where only 2.5" long so they didn't work.
Oh boy, and what a bi.... it is to get the screws behind that box. Due to the thickness of the firewall, you will need at least 1" long 1/4"-20 bolts. I drilled the needed mounting holes in the box out with a 1/4" drill bit and then drilled through the firewall in the fuse also and expanded that hole (not the one in the box but in the actual fuse) with a dremel saw drill (you know one of those that look like a drill bit) wide enough so the head of the screw would fit through it. I then inserted the screw from inside the fuse all the way to the front through a washer which I inserted through the openings in the box holding with needle nose pliers . That was the only way I could figure out on how to get the screw from the inside through the box without having to butcher open the whole box. Just had to cut the openings (slids in the box) a little bigger, since I used a large diameter washer to spread the load. Came out pretty clean. Did I make sense here, or was it to confusing ?
The DA fits nicely under the cowl, and I think only a minor opening will have to be cut for the spark plug cap.
The supplied 4" spinner looks neat, but does not hold those larger props like the Biela (wil be using that one) or Meijzlik. Will have to buy me a nice Tru Turn Ultimate spinner. Anybody wants to buy the supplied 4" spinner from me drop me a PM.
Anybody flying theres yet ?
