P-51D Bugs and Observations
« on: February 18, 2004, 05:23:22 PM »
1. MP guage at 10 inches when engine is off. It should be at the atmospheric pressure at ground level. Usually about 29-30 at S.L.

2. Observational question:
RPM reaches 3,000 at 20 inches of MP with only a slight advancement of foward throttle. I know 30 inches is max on non-supercharged engines. At what point should supercharger kick in i.e. throttle advancement position?

3. *EDITED* With the throttle fully closed, no matter what attitude, the rpm will not fall below 3,000 unless airspeed reduces below 149 mph, which then it reduces to only 2,700 rpm. Below 100 mph (on ground roll only) -rpm reduces to 2,100. During the stall attitude, the throttle is fully closed, there is no POWER to spin the engine-prop. The only reason/s it spins is from the all ready spinning forces as well as the relitive wind "windmilling" it. Should the rpm stay that fast?

4. The engines sounds are beginning to make sense when the plane is flown realisticly, however, I think it can be improved. It still looks as if the rpm is tied in with airspeed instead of airspeed and power!

5. Almost takes half power to taxi. About 1,700-2,000 rpm.

6. No tailwheel lock

7. deadband screws with taxi due to delay in rudder movement.

8. Manifold Pressure does not decrease as altitude increases.

In Addition...When playing offline...I did not have any muzzle flashes for any of the guns....All six guns fired at the same time when only firing primary (2 inboard guns)...I rechecked my joystick setup and did not have all guns mapped to one button...played ONLINE and did not see the same problem....The sun still barely shines through the windscreen frames...and now it appears the guages on the dash are just a bit fuzzy...just my 2 cents..Am getting better frame rates(25-60)
