Yeah, like most RTR kits out there, the stock electronics is ''average'' at best. The servo is barely up to the task. It is reasonable enough out of the box, but you can definitely get better performance with an upgrade. It can wait until you destroy the stock one, though.
Other than the servo everything is quite good up to standard, and I am quite happy with it. Now my MT4 sit on the shelf waiting for the lovely servo to come.
