It appears that some of the kits from Great Planes had
wrong incidences on the tailplane , wing, and wrong upthrust.

Check out the other thread on the G202.

I have one that I am building (putting together) right now.
I have an OS160FX with a Bisson Pitts mulffler


I was not happy using the CA hinges so I have replaced them with Dubro 1/4 scale hinges. Quality of the kit is excellent.
I could never build it with the same finish for the price.

From Annemarie at GP these are the correct incidence angles.
tailplane +1
wing 0
upthrust +1


So far when they are set up correctly everyone says they are
excellent to fly.....I cant wait
