The EX-2 revision includes an extensive series of improvements and upgrades to the kit, but the primary components are the new G-Series ailerons,
flaps, and tail feathers. The G-Series control surfaces of the EX-2 improve controllability in all aspects of the flight envelope.
The roll authority of the Carbon Cub EX-2 has been improved by redesigning the aileron airfoil and relocating the hinge point.
CubCrafters' G-Series ailerons deliver markedly lighter and crisper roll response compared to legacy aircraft. Control harmony
is even better than the original.
The G-Series flaps are the first truly slotted flaps available from CubCrafters. With the G-Series, the stall speed of the EX-2
with flaps extended is reduced, thus improving the already remarkable low-speed manners of the Carbon Cub. The G-Series
flap features repositioned pivot arms that, when deployed, lower the flap's location relative to the wing, forcing high-pressure
air from below the wing over the flap, and helping airflow to remain attached to the flap surface for increased lift.
The G-Series tail feathers feature new adjustable elevator stops and allow greater down-elevator trim, providing the pilot
with greater trim authority when operating either at the forward or aft limits of the CG envelope. With these improvements,
CubCrafters has made an already stellar performer even better.
