RE: World Models Mach II ??????
I have had one for about a year now. Flys very well. I am running an old OS 40LA in it and have more than enough power. I installed large servo arms on it to get max throw on all control surfaces. Since the rudder is so small it doesn't like to knife edge. I am planning to enlarge the rudder this winter to improve knife edge. The plane is very light so it does get bounced around in the wind which can be expected. A few weeks ago I had a mid air with a helicopter rotor which destroyed the wing tip. The plane keep flying like nothing happened. It was an easy fix and is back flying again. The color scheme does tend to disappear in the sky especially on cloudy days. I see WM change the back end color scheme to help correct this problem. I added a red checker board to the bottom of the wing to increase visibility. I fly it off the snow in winter with Dubro skis. You can't beat this plane for the price. This would be a nice plane to convert to electric because it is so light weight.
Have fun.. ..
