I wonder why they choose such a high time airframe to make a reimagined 152 out of.
Yes. Of all the 152s available, they could have used one with much lower airframe time.
Initially when this "concept" was first proposed, the candidates were SUPPOSED to be low-time airframes. Engine, paint, upholstery and panel avionics are equally upgradeable on ANY airplane.
I suppose if you brought your 152 to Aviat they would perform the restoration regardless of the time.
Only the manufacturer can "zero time" an engine/airfirame.
