SailFly - X Thrust Test, Lap Times and Durability Problems

The Sailfly X is one of the lightest and fastest Toothpick style quadcopters out there. It is very fun to fly with a power to weight ratio above 4. The big problem is the CrazyBee F4 Pro V2.1 Flight Control board is prone to failures. Lets hope Happy Model replace the V2.1 boards with the newer V3 boards that I have not had problems yet with the Larva X.
