Don't forget Wren, some of their newer turbines have a 50 hr service life!
Istarted with a kit MW54 and have never had a problem with a Wren that required it
to be serviced! This includes the SuperSport, 44 Turbo Prop and 3, 160's.....Every time Itried other brands Ihad issues
(no not naming them )

In terms of starting method... Idon't care if my turbines start with propane or kero just so they start reliably and quickly
SO I can go fly.....
