i have just sat here and all these posts about pc-9's going in because of a substandard kit.
yes they are cheap but, you get what you paid for.
i have one of these for over a year now.
i use a mds47 with a tuned pipe and a 11x6 mas prop.
this thing screams. i think i tached it at about 12500rpm running it a little rich.
i could not count how many flights i have had with plane and no matter what i throw at it, it just comes back for more.
the only time i have had to repair the plane was when the tail fin grabbed the strip while doin inverted low passes at full throttle. all i had to do was put another tail fin and canopy on.
