The Curtiss P-40E Kittyhawk (ICAO: P40 / WAKE: LIGHT) , also known as Tomahawk II or Warhawk, is a single-seat vintage fighter and fighter-bomber. Created in Second Life by ZSK Digital Designs, the plane was based on the iconic real-life Curtiss P-40E Kittyhawk, an American fighter aircraft mostly used by the USAAF, RAF, RAAF, and RNZAF during World War II in the European, African, South-East Asian and Pacific theaters.


Produced by ZSK Digital Designs for Second Life, the aircraft is closely referenced to a real P-40E Kittyhawk in order to bring a unique and realistic experience to Second Life's Aviation and Combat communities.

The ZSK P-40E is most popularly known for it's upgraded physics core, which makes the previous physics core easier to fly but still allows fast diving speeds and the ability to dynamically stall and enter a spin. The ZSK P-40E is also one of the first aircraft to use script based interchangeable Specular maps and an adjustable Advanced materials system, which can be accessed by the aircraft's menu.

The P-40E is a combat ready aircraft that is equipped with a VICE 1.2.0 combat system and can also serve as an Acrobatic aircraft for airshows.

The P-40E Kittyhawk was officially released on September 26th, 2014. An update, version 1.02, was released on December 6th 2014.

The aircraft is sold with the P-40E Kittyhawk aircraft and combat aircraft, a display model, a target model, personal/merchant paint pots, Heads-up display (HUD), blank/templates, and ZSK's Custom Paint Assistant Tool (CPAT).

Physics Core

The P-40E uses a ZSK Flight Physics core version 1.4 which was originally based from an Astral Technologies F-16C Fighting Falcon flight physics engine and the Laminar Systems lift code from their Laminar Flight Engine (LFE). 

The ZSK Flight Physics core is based on a 1:6 measurement scale and has been specifically optimized for the P-40E's Mode B, and Mode A physics settings.

Mode B is the Standard physics setting and has the easiest physics behavior to fly. The plane will auto-yaw into turns, will not loose lift when rolling or flying inverted, has a limiter on it's diving speed and is generally stable when entering and during a stall.

Mode A is an Advanced physics setting and has a more complicated and realistic physics behavior. The plane will loose lift when rolling or flying inverted, has an unrestricted diving speed limiter, and deep stalling will cause uncontrolled spinning and unstable flight conditions. A pilot can counteract the spin by pushing the nose towards the ground, applying roll and yaw in the opposite direction of the spin, and applying power to the engine.

Combat System

The P-40E is a combat-ready aircraft that is equipped with a VICE 1.2.0 combat system with it's weaponry scripted by Astral Technologies.

List of the P-40E VICE stats:
