Attached is a beta test FM for Veltro 2K's Hawker Tempest V, available here: https://combatace.com/files/file/14831-tempest-mk-v/
I will be doing some FMs this winter for Battle of the Bulge use. This one was relatively simple as I could use my Sea Fury FM with a few edits and a new engine table. The min/max extents have been done and some basic collision points added. Still have to take a closer look at the AI behavior but will leave that until I get some more late WW2 planes installed.
Some things to note about my WW2 fm's:
I spend quite a bit of time working on the engine table and tuning the CD0 values to get realistic speeds. The max speed at sea level for this 100 octane Tempest is about 372mph, very close to the 374-378mph range from actual flight tests. The maximum speed occurs in the 18000 to 19000ft range and seems to be within the test data range of 432-436mph TAS.
In the data.ini, for MaxSpeedSL=xxx, I use the maximum indicated airspeed the plane is permitted to fly at. This is quite an impressive number for the Tempest V, from the flight manual: 10000ft-540mph, 20000ft-450mph and 30000ft-370mph. At standard atmospheric temperatures and pressures, those speeds work out to be Mach 0.836!
From some light historical research I get the impression the Tempest V's were used mainly for low/mid altitude fighter sweeps, V-1 intercepts, strike missions, and armed recon missions. For armed recon, they usually were guns only and a couple of streamlined 45 imp gal drop tanks. Veltros model comes with the larger 90 gal tank. Wikipedia says the Tempest V wasn't equipped with rocket rails until the post war period but I know for sure the Tempest was tested with rockets early in the development period so it may just be that the RAF brass thought the Tempest was better used in other roles while leaving the rocket work to the numerous Typhoons in service. Postwar, the Typhoons were quickly scrapped and the Tempest took over their role. The service end date for the Tempest appears to be 1948 but keep in mind the light research.
With a decent roll rate, good visibility, great low to mid altitude speed and climb rate, and a turn rate probably somewhere between the Bf-109 and FW-190, the Tempest was an excellent dog fighter at low and mid altitudes.
ISSUES:
The propeller on the Tempest V rotated counter clockwise when viewed from the cockpit but the propeller on this model is angled for clockwise rotation.
The biggest issue is with the weight distribution when carrying bombs. For some reason, when carrying bombs the plane flies with the right wing down. It's very noticeable and annoying. I spent two days trying to figure out what was going on but now have to assume it's a model issue. When carrying drop tanks there is no problem. When carrying rocket racks, there seems to be a small amount of left wing heaviness but I can live with it. The reason I think it's a model issue is because when I remove the bomb racks via ini edit, the problem disappears. Unfortunately, a quick check on Veltro's Typhoon shows the same problem. For now the racks are removed while I try and think of a work around. It might be possible to make some "special" bombs with no weight but all the explosive power of the regular bombs and use the SpecificStationCode=xxx. That's all I got at the moment, any other ideas?
