I watched Viper fly at least 5 times this past weekend and since I launched for you every time, I watched each flight closely and I was really impressed. That plane is special!!! As you get more time on it, I think you will see big improvements in your flying. The road to the 2014 Nats is already 60+ days old. You have a great head start as you have not one, but two great flying planes!!! I did not see any bad tendencies in either plane but Viper just stood out above the rest. Just keep flying that plane, the results will come.
