I love my synergys, my 516 is for insane 3d, my e-5s is my test a new mannver ship, my e-7se big 3 d monster, the 766 is like my pattern ship, great for big air 3d. Ihave learned so much with this ships. I have been flying a lot now I had back surgery fused from L1- L4 most of the pain gone. The other week i got 34 flights in. Pushed my e-7se so hard i had tail boom strike, my fault dampers were worn out over 2300 flights. All rebuilt now, (Thanks Matt) Going threw all my ships now. Getting ready for another summer of insane flying.
