I have 4 cmp,planes,Quest 50,brand new not flown yet,a Magpie flys great,a Chipmonk decent too much +incodence and a lark with a ttpro61 also flys great.I never use their push rods.I use GP solid pushrods.Horns are good.Just STAY AWAY from the 40 size staudecher,real nice looking plane and kit had 2,the first one crashed,It was twitchie just flying level,when landing all I had was adverse Yaw.Not too much control - 40%expo,CG was good,elevator control was good,no snaps when looping.slight + incodence.The 2nd one had the same problem,I have been doing this for 35 years,so I'm not a novice,like the Giant scale.com rep called me at the wrams show.I have a total of 22 assorted planes ready to go.Thanks ed
