I have had JetCentral, Simjet, Jet Cat, and Wren The Wren has been the smoothest and easiest starting of the bunch and Ihave never had to send one back yet (knock on wood)for service.
Other issues:JetCentral... turbines not smooth runningand uses WAY more fuel that others (falcon )
Simjet: almost as smooth running as wren but have more difficulties spooling up when the weather gets warm ( nexus)
Jet Cat: fair service but there you are.... Ihad to send 2 back for service (P80+120)
So far the Wrens just keep running... Iuse Castrol TTS oil @ 5%
And in an earlier post,someone said that the 160's etc have 50 hrs between suggested bearing replacements
WOW if ev flight was 8 mins that would be 50x60/8 or <u>375</u> flights before you have to worry about bearing replacement
that alone is awsome.. shows the superior design+construction of these turbines!!!! (+how many planes last 375 flights before they reach thier expiration date for other reasons?)

ALSO the 44 Turbo Prop puts out 36-37 lbs of thrust while using a meager amount of fuel doing so
