Pine asks about the best place for the hydraulic powerpack and hardpoints...

I put the unit behind the passenger seat on my 360.  This was recommended by
Orrin at Lancair.  It has turned out to be a blessing since you have to monkey
with the installation, plumbing, wiring, testing etc.  quite a bit.  Getting
back behind the baggage bulkhead to do all these  things would be a real
stinker.  Othe benefits are that the wiring and plumbing are a little shorter,
easier, lighter.  Depending on how you want to orient the unit, you'll need to
fabricate a small bulkhead to mount the pump against.  I cut a hole in the
seat
for an access panel so that I can get at the system.  You'll see all this when
you get to that point.  

Concerning hard points, you have a good idea.  Shape doesn't matter, just
distribute the loads in a reasonable manner.  I generally did mine with the
dremel and jig sawed the phenolic but you have a good idea.  

Somebody else mentioned replacing the nose gear gas strut on the IV when it
gets
easy to compress.  On the 360 the procedure is to test the free fall
capability
in-flight with the pump disabled.  If the strut doesn't push the nose gear
down
against slipstream, replace it.  Does the IV not have this procedure?

A list of max. bolt torques is provided in the Lancair 360FB builder's
manual in
the engine installation chapter (21 I believe).
