Updates

4/7/2021  Version 1.0.3:  Redid UV maps and normals in 4096x4096 for all exterior textures.  Remapped to all exterior textures.  Eliminated multiple distortions and misplacements. New mapping will not work on prior versions of the model.  

4/7/2021  Version 1.0.3:  Added working magneto-battery switch, added foot-starter, separated rudder-brake pedals to proper spacing.

The Curtiss P-40 has become one of the most famous and used aircraft of the Second World War. Between 1941 and 1944 he also played a key role in many operational theaters from North Africa to Italy, from China to the South Pacific. Characterized by a very robust and reliable aerodynamic structure, the Curtiss P-40 was equipped with an Allison V-12 engine with a single stage mechanical supercharger, capable of delivering more than 1,150 HP up to 16,000 ft.  It had a service ceiling of over 28,000 ft but above 20,000 ft it was inferior in climbing ability to the Bf 109 and Fw 190, however it could out turn and out dive both. Below 15,000 ft and below 250 mph it out-performs both a Bf-109 and a P-51. It served as air superiority fighter and fighter bomber. Used by U.S. fighter squadrons and, as Kittyhawk, by Commonwealth Air Forces, the P-40E was heavily armed with six 50-cal. M2 Browning machine guns installed in the wings. Furthermore, thanks to its under wings hardpoints, able to carry nearly 500 lbs. of bombs, it for close air support.

Between 1941 and 1944, the P-40 played a critical role with Allied air forces in three major theaters: North Africa, the Southwest Pacific, and China. It also had a significant role in the Middle East, Southeast Asia, Eastern Europe, Alaska and Italy. The P-40’s performance at high altitudes was not as important in those theaters, where it served as an air superiority fighter, bomber escort and fighter-bomber. 

The P-40 performed surprisingly well as an air superiority fighter, at times suffering severe losses, but also inflicting a very heavy toll on enemy aircraft. Based on war-time victory claims, over 200 Allied fighter pilots from 7 different nations (United Kingdom, Australia, New Zealand, Canada, South Africa, the United States, and the Soviet Union) became aces flying the P-40, with at least 20 double aces mostly in the North Africa, China-Burma-India, Pacific and Russian Front theaters. The P-40 offered the additional advantage of low cost, which kept it in production as a ground-attack aircraft long after it was obsolete as a fighter.

Aircraft Represented:

1. Curtiss P-40K-1-CU “Yellow 55” typical P-40 in an advanced training squadron. USA 1943.

2. Curtiss P-40K-1-CU (serial number 42-45979) “Pistoff” 49th Fighter Group (FG) (“Fighting 49ers”), 7th Pursuit Squadron (PS) United States Army Air Force (USAAF), Dododura, Buna, New Guinea, 1943. Flown by Lt. Donald H. Lee, Jr.

Here is a nice write up on Lt. Lee and “Pistoff” with the 49th FG.

3. Curtiss P-40E (serial number unknown but listed as 11456) “White 7” 29th Fighter Group (FG), United States Army Air Force (USAAF), China, September 1942. Flown by Lt. Col. Robert Scott, Commanding Officer (CO) 29th FG.  He called the fighter “Old Exterminator” but that was never painted on the aircraft.  Col. Scott is the author of “God Is My Co-Pilot”.  Col. Scott is credited with 10 kills in P-40s.  It was standard practice in the CBI that the serial numbers were painted out.

It is a wonderful simulation, thank you, well done.

I have made a video of a P-40 Warhawk performing "touch and go" with step by step instruction to fly this plane.

I am not a flying instructor and the figures chosen are not necessarily the official ones.

I came to these figures by trial and error and they seem to work fine for this plane in this game.

Livery of the famous shark-toothed "Flying Tigers" of the American Volunteer Group in China during WW II would be nice.

Very nice aircraft. my favorite WWII fighter. I guess the AI is why I have no problem taking off.

She also lands well. Wonder if the AI is also there as well.

I am not able to fire the guns on any x-plane fighter, I wonder why that is?  Any input would be welcomed.

Once again, wonderful job. Thank you very much.

 

  

Whenever I’m in the mood for some sightseeing fun, this is my “go to” plane. Nicely done inside and out. Keep up the great work,

  

Works ok in 3D runs and flys as you would expect. Here is my review flight.

 

  

Quite nice already for an 'alpha', as you mention yourself. Thank you very much.

On first impression, I had trouble controlling the aircraft. The rudder seemed to also want to control the ailerons and it immediately flipped on it's back after takeoff. It looks like it'll be a fun airplane to repaint, as there were thousands of different liveries for P-40's both during, and after the war. Not sure if I can fly it though, but I'll work on it. Maybe it just needs a separate joystick profile. It's a start.

Response from the author:

Like a lot of overpowered taildragger WWII fighters, the P-40 included, they are difficult to take off. I added a very mild artificial stability below 85 kts (100 miles per hour) to help with that.  The best way to take off is to point the aircraft straight down the runway, have 10 degrees flaps, accelerate with 50% power to about 50 miles per hour, lift the tail, add power to 75 to 80 percent, let the aircraft fly itself off at about 90 to 100 miles per hour.  Around that speed, the AI will cut off and the aircraft will attempt to turn left due to the engine torque, use the rudder to keep it straight. 

What you are seeing on the rudder and ailerons, below 80 miles per hour is the AI attempting to keep the aircraft straight.  You should not try to chase it and left the AI do its job.  This will present ground loops or worse. 

There were a lot of accidents in training with the real P-40s due to ground looping the aircraft as it was quite unstable at low speeds when proper techniques were not applied.  Most X-Plane pilots would have real trouble with this aircraft which is why I added some AI to help out.

If you watch some of the youtube videos of the remaining P-40s taking off (with the pilot commentary), there is two things that are evident, first, there is about 2 to 4 degrees of right rudder trim added, second, the pilot, has his right foot through the floorboard and the stick to the right  to countact the torque. The right aileron and right rudder are progressively removed as the aircraft speeds up with the pilot keeping an eye on a point on the horizon.  This is very difficult for most X-Plane pilots to do because in the sim the visual feedback is not there.

This is still an Alpha and I am still tweaking the flight characteristics.  I have upgraded the CG at bit to get closer to how this aircraft really flew.  If you are interested, drop me a PM and I will send you the unpublished upgrade.

Allison powered and lovely. Thank you.  Attached is the exhaust flame info from the manual.     RML

Response from the author:

cool. I will have to figure out how to model this.

Thank you for the successful implementation. How do I open the cockpit canopy?

Response from the author:

The cockpit opening is tied to the spoiler command.  In the 2-D cockpit, there is a slider.  The 2-D presentation can be reached by Control-7 or Alt-W.    You can also map a control on a joystick to the spoiler command and use the control to open and close the cockpit.

This is a very well done example of the wonderful P-40 aircraft. This iconic aircraft flew for many nations during WW II and is famous for the USAAF Flying Tigers. Both the internal and external presentations are outstanding and in my opinion are payware quality.

Seems we have some great WW II subjects available to us as freeware lately with the Spit, Storch and now the Kittyhawk. This aircraft is essential for WW II flight enthusiasts and should be a keeper in every hanger. Thank you for the hard work bringing this to the community. Please keep up your great work.
