The E3 model of the Warhorse is designed for longer range escort missions, and has been modified to fit that role. The engine has a new, more efficient oil cooler to replace the standard cooler, allowing engine performance at full throttle to be improved. Two under wing hardpoints have also been added to carry two external fuel tanks. The internal tanks have been expanded as well, extending the range even further. A long range radio has also been added, with its antenna wire stretched between a new antenna mast behind the cockpit and the top of the rudder. The cockpit its self has not changed, but it still is a detailed custom cockpit instead of a standard cockpit block. enjoy.
