RE: YAK-54 ARF
I would be extremely reluctant to buy a YAK54 from an offshore source without checking it's specs with ExtremeFlight first. ExtremeFlight rejected a model run of several hundred of these planes because they did not meet ExtremeFlights quality standards, I have been told by them. That is supposedly why they are still waiting for planes to come in from their new manufacturer. All those planes had to go someplace.
