One of the most iconic aircraft from the Pacific theatre of WWII


One of the most iconic aircraft from the Pacific theatre of WWII, the Corsair was also arguably one of the best performing. Deployed primarily with the US Marines, the aircraft achieved a staggering 2,140 air combat victories against 189 aerial losses - an overall kill ratio of 11:1. The Corsair also carried over 70% of the total bombs dropped by US fighter aircraft during that conflict, flying just over 64,000 sorties combined.

It's really no surprise that such feats required an exceptional aircraft, which the Corsair indeed was. Powered by the 2000 hp R-2800 Double Wasp coupled to a huge three blade propeller that measured 13 feet and 4 inches, the aircraft was a fair bit faster than the F6F Hellcat and only slightly slower than the P-47 Thunderbolt, with the difference more than acceptable considering that top speed on the P-47 was reached at an altitude of 30,000 feet, while the supercharged Corsair reached it's maximum speed at 19,900 feet!

Our Corsair is loosely based on a FG-1D that was produced too late for active service in WWII; BuNo. 92132 spent it's naval career in the Reserves before it was retired in 1957. Brought back to life in the 70's for a brief stint in the television show Baa Baa Black Sheep (later syndicated as Black Sheep Squadron), this particular aircraft then languished again for a few decades before being acquired by the Tri-State Warbird Museum in Batavia, Ohio, where it is now being lovingly restored to original condition.





Superior Flight Dynamics

Replicating the complex flight dynamics on such a powerful and high performance aircraft such as the Corsair is no easy task. However, our expert FDE 'artist' has employed every bit of a considerable amount of knowledge, testing and teamwork to arrive at an aircraft that compares closely to the real thing - an aircraft nicknamed the 'Ensign Eliminator'.

The MilViz FG-1D rewards attention and masterful flying; by-the-numbers capability is available at all flight regimes. Proper technique will be required to recover from stalls, as well as for performing for safe landings and textbook take-offs.

MVAMS Integration

Our innovative MilViz Aircraft Management System (MVAMS) is included with this release. It allows for easy control and set-up of the aircraft, including configuring the default start-up state, radio frequencies, as well as allowing the setup of a joystick axis for the two-stage supercharger. It also allows for easy notification and application of hotfixes as they are released for your aircraft.

TacPack Capability



The Milviz FG-1D comes complete with full TacPack capability, enabling you to operate the Mark 8 illuminated gunsight, fire guns, drop bombs, or launch rockets from your now-armed-to-the-teeth Corsair. Weapons are selected in-game via a loadout manager, letting you configure your layout however you like.

Separate TacPack software required for full weapons functionality; TacPack software not included.

I am thinking "Baa Baa Black Sheep" and the legendary tough-guy World War II fighter ace Pappy Boyington.

Propeller Torque
Mon Jan 06, 2020

In the latest version, there is a CG offset that essentially adds 3000+ lbs-ft of roll torque. I believe this was a work around, due to the lack of torque effect in the sim. After some testing, I've discovered the reason for the lack of propeller torque.

First, in the [weight and balance] section, restore the CG

//empty_weight_CG_position = 2.6, -0.321, -0.5
empty_weight_CG_position = 2.6, 0, -0.5

Then, in the [reference speeds] section, set the stall speed to a large value

flaps_up_stall_speed =999999 //98.24250

Note, this will also cause the stall warning to disappear, but it's a worthwhile tradeoff

The reason for this is because torque goes to 0 at 1.5 times this speed. Makes no sense, I know....

Finally, the sim only applies engine torque and not propeller torque, so for airplanes where the reduction ratio is greater than 1, you are not getting the full effect.So, the scalar needs to be increased to match the reduction ratio in the [flight tuning] section,

torque_on_roll =2 //1.00000

You will probably need to do this for every piston airplane in your collection, certainly all the WW2 types.
