Just to update on my Vmar 540 edge. I finished the plane and flew it 6 times... It flew pretty well at half throttle or faster.( .61 2 stroke instaled), but any type of low speed flying it would loose lift and tip into a dive... I know it's part af flying that type of plane but the VMar Edge is heavy and it's very easy to loose control if you are not an experienced pilot... You definetly have to be one step ahead of it. If I had to do it again I would have saved a little more money and baught a different brand. Just my pinion...
