Freewing A-4E/F Skyhawk User Manual page 2

Introduction
The A-4 Skyhawk commands a beloved place in aviation history. Designed by the innovative Ed Heinemann
for Douglas Aircraft in the 1950s, the A-4 was optimized as a multi-role aircraft that used its low weight, high
maneuverability, and straightforward reliability to lethal advantage. This aircraft's nearly 70 year history of
distinguished service and its continued operation by certain countries to this day is testament to the
timelessness of "Heineman n's Hotrod."
To honor this famed aircraft, Freewing and Motion RC proudly offer the Freewing 80mm A-4E/F Skyhawk,
the first large foam electric PNP mass production A-4 in the world!
This flying model is powered by a 3530-1850kv brushless outrunner motor and 12 blade EDF
ducted fan, achieving a top speed of 106mph/170kph using the recommended 6s 4000mAh-5200mAh
battery.
The Freewing 80mm A-4E/F Skyhawk features all new fold-and-twist retracts, with durable aluminum trailing
link struts for confident operation on rough grass runways. Removable wings and flexible wing wire harnesses
make transportation very convenient. Beyond the overall scale profile fidelity, other scale details include plastic
split flaps, and detachable fuel tanks, AGM-12 missiles, and refueling probe.
Adding to the model's versatility, the later version avionics "hump" is also included! Attach this magnetic
"hump" onto the fuselage's top spine to change between the -E and -F variations of the Skyhawk. Two decal
sets are also included, depicting a US Navy A-4 from VA-22 and a US Marines A-4 from VMA-311. Fly these with
pride, or personalize with another livery of your choosing!
