Subject: [LML] Re: Necessity of A/C in IV-P? IV-P still beats EA50

interesting comments John:

let me point out a few differences:

I have seen many IV-P's in my career, I pay attention to all of them

I even watched a guy in the dallas area hire a bunch of roofers build 4 IV-P's in succesion until the FAA got him out of the business.

Every one is a bit different and depending in who built it the quality changes.

I spent 6 years with a mechanical engineer with expertise on aircraft adhesives as my main builder assist with whom I spent the entire 6 years doing my IV.

In contrast all Evo's are factory matched, built with factory assistance, no chance of leaving the plastic protective layer in prior to hysol (like one unfortunate mexican builder who did not know about that layer and the airplane had to be trashed)

all evos flying have been built (with one or 2 exceptions) with major factory supervision

power plant is usually a well know PW with years of experience and no shock cooling or cylinder unexpected failures (or crankshaft separation) or worries about who used LOP or ROP etc etc etc.

the airplane is not demanding in landing (I land mine at 70 kts with no trouble) so you wont see the deadly stall in turn to downwind scenarios. 

I wont hesitate to purchase an used Evo any time

I will certainly hesitate a lot about buying an used IV-P for the above reason

but I have been wrong in my life so many times that I would not dare put a cent in aviation. Flying is fun to me so far

and I have not been paid by the factory to say all this.
