Anybody building and flying this ARF. I am almost done putting one togather. I am putting a YS 120 four stroke engine (NIB) in it. Engine was purchased about 4 years ago. Any advise on the plane and engine will be a big help. This is my first YS engine and I read that they can be hard to tune. Will this plane be hard to land? The only bi-plane that I have flown is a Phanton 90 and it is real easy to take-off and land. Thanks for any help. WayneM.
