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.=A0 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.=A0 I’m sure those = still building would also appreciate more of you chiming = in…

 

Would Definitely Do = Again:

=B7         = Forward CG.=A0 Bias your weight and = balance decisions toward a forward CG.=A0 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).=A0 Also saves a = significant run of heavy gauge wire to the rear.

o   Hydraulic pump = to the back of the seat.=A0 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.=A0 Improved, take-off and cruise performance.=A0 Also, the heavier = prop will help your CG picture.

=B7         = Tim Ong shocks on the main gear.=A0 = Wouldn’t fly w/out them

=B7         = Lightspeed Engineering electronic = ignition in place of 1 of the magnetos.=A0 I started w/ 2 mags and when = one failed and needed replacement I switched to the Plasma III model of = EI.=A0 Best modification I’ve done so far.=A0 I now run = lean-of-peak, high altitudes (mid-teens), and burn about 10% less fuel = at the same TAS as before the EI.=A0 The fuel economy of this little = bird is amazing!=A0 (typical cruise 15,000’, WOT, 2300RPM, 5.8GPH, = 182KTAS).

=B7         = Fuel injected engine (see comments about = lean of peak above)

Would Not Do Again:

=B7         = “Smooth Prime” primer.=A0 = This stuff is water based and shrunk over time.=A0 The result is that a = year after painting the plane I started to see the fiberglass cloth = weave in the reflections of the paint.=A0 Especially bad in the hangar = under fluorescent lights.

 

I hope this = is helpful and motivating to those of you still building the 320/360.=A0 = Feel free to contact me offline for additional questions or = clarifications.
