When you say that you “turn on” the = ram air induction – do you have a flap or something?=A0 Why turn = it off?

 

Just = curious,

Guys,

 

Yesterday I = posted a message asking you IV-P builders for the benefit of your = experience as I begin construction of my IV-P kit.  So, I thought = it would only be fair if I post my thoughts as I reflect back on the = construction and 7 =BD years of flying my 320.  I’m sure = those still building would also appreciate more of you chiming = in…

 

Would Definitely Do = Again:

=B7         = Forward CG.  Bias your weight and = balance decisions toward a forward CG.  The airplane flies better = here, the factory expanded the forward limit and you will end up having = a useful capacity in your baggage area:

o   MKII tail and = motor mount (the MKII motor mount moves the engine 3” = forward)

o   Battery on the = back of the firewall (vs. in the rear of the fuselage).  Also saves = a significant run of heavy gauge wire to the rear.

o   Hydraulic pump = to the back of the seat.  Also makes servicing the pump much = easier

=B7         = Constant speed prop –you will want = this to accommodate the wide speed range of this wonderful little = bird.  Improved, take-off and cruise performance.  Also, the = heavier prop will help your CG picture.

=B7         = Tim Ong shocks on the main gear.  = Wouldn’t fly w/out them

Would Not Do Again:

=B7         = “Smooth Prime” primer.  = This stuff is water based and shrunk over time.  The result is that = a year after painting the plane I started to see the fiberglass cloth = weave in the reflections of the paint.  Especially bad in the = hangar under fluorescent lights.
