Im on my second incarnation the first got too close to the ground at high speed ground 1/ synapse 0, but that aside these little jets are great fun to fly when you get the hang of them, they fly best at full thottle due to very little wing area. They have to be launched at full throttle and be ready to make quick corrections, i also found by cutting the rates back it helps heaps when flying for the first time. When doing high speed turns you have to feed in a bit of elev because the wings tend to want to drop too much, again due to wing area being small and maybe not quite fast enough. These jets are not for beginners but when mastered they are good fun and get along at a fair old speed. i am now looking to upgrade my motor and run a 4 cell setup this should really make it go.
