Hi 

How critical is the 3 deg to vertical opening of the outboard gear door ???
The old plans referred to a 10 deg opening ??

[The operation of the outboard gear door is governed by the geometry of
its attachment to the main gear strut... in other words, it is simply
along for the ride and it seems to me that its angular relation to
vertical is determined solely by the action of the gear.  I would say that
what you should be shooting for is unobstructed motion throughout its
arc of travel and be willing to live with whatever angle it winds up at
when the gear is down and locked.  The important considerations here 
are that the gear is perfectly vertical when extended and that the wheel
doesn't push against the top skin when retracted.  With those conditions
met all you can do is rig the door so it is seated properly with the gear
up and accept the angle it makes to the aircraft when the gear is
extended.  You can fiddle that angle a bit by adjusting the position of
the gear in the well, but as you have probably seen by now, there is 
little room for adjustment of the gear's retracted position.  Relocating the 
position of the gear door pushrod will change its angle but there aren't
many options for where to locate bolt which attaches it to the gear
leg.  This is just my opinion on this matter... other folks may have a
different viewpoint.            <Marv>      ]
