Hi Couch Flyer I have a Sukhoi with a 106 qs in it my first year in unlimited. I have tried several 33%er and a 40% radio craft for a couple months this spring and my SUKHOI does a pretty good job. The strong points I would say is the down lines and rolling circles.The down lines required no mixing with the throttle and nice and slow.You have to add throttle for clean snaps going down.The rollers are the easiest I have tried.The negatives are you need to run a 12 pitch prop and timing your roll stops it seems to want to over rotate a little.For the price I think it is a good plane for IMAC. And I love the 106QS it has great power.Just my opinion I am definitely not a expert but it is a fun air plane and it seems to be tough. Mark,
