Designation: F-39A Thunderboa II

F-39A Thunderboa [Early - 1949]

Brief description and lore:

• The Thunderboa-II, a transonic, more modern version of the original airframe. The Thunderboa-I was never officially released, but instead underwent significant upgrades, such as improved flight characteristics, afterburners, more advanced weapon systems and more efficient engines, in order to meet the changing times of the war.

• Its design origins can be traced back to the iconic Viperwing lineage, which forged its reputation as a formidable force in aerial warfare.

Instructions:

AG1 - Open/Close Canopy
AG2 - NAV Lights
AG3 - Cockpit Lights

AG5 - Airbrakes

Engines, Take-Off and Landing

• Both engines can only start once turned on using the two switches labelled "Eng.1" and "Eng.2". If only one engine is on, afterburner will not engage.

• For take off it's the usual. Set flaps (VTOL) to 50% down and throttle up.

• When landing (without payload) throttle down to 5% and set flaps (VTOL) to 100% down. It can also land on the carrier, but you might need to use the airbrakes (AG5).

Reticle

• The bottom of the outermost yellow ring indicates the estimated flight path of the 'Javelin' rockets when launched from the aircraft at distances greater than 1 mile from the target.

• The second yellow ring indicates both the estimated flight path of the rocket within 0.5 miles distance from the target as well as the area of effect of the gun.

• At the very center where the 'cross' is, indicates the area of effect of the nose mounted canons.
