I flew mine yesterday and Wow!!!! It was really twitchy on take off and through out the flight. I only had -40% expo dialed in on the ailerons and that proved not to be enough at all. I had a very difficult time controlling it. On take off it rolled hard to the left and I just about lost it. I input hard right aileron and barely saved it. I highly recommend higher expo especially on high rates. The plane is really fast as I have a Magnum 120RFS matched up with an APC 15x8. On my first landing I hit hard so pulled up for another go. On my 2nd landing attempt the right gear folded up and I lost the wheel causing a skid to a stop. Damage was very little but I'm happy I was able to get it down relatively safely and with minimal damage. After getting softer on the sticks it flew well. I like this plane, can't wait to fly it again.
