Cant find the prop size in the FM. Do you know the name?..

It is set in the .emd, these:

Code: [Select]
[Generic]
  PropMass ...
[EngineName]
  PropDiameter ...

Sorry I can't copy from the Ryusey FM, I'm from my working computer...

Cant find the prop size in the FM. Do you know the name? Also found this....

[Mass]
  Empty 2500.0
  TakeOff 5200.0

I'm wondering if the take off wiehgt is too much.

But it's historical parameter, I find.

There is need to check the parameter.
Here is B7A1's spec from the IJN official spec seat written in 1945(I copied it at the Military Archival Library of the National Institute for Defense Studies in Tokyo).
Weight section says that empty weight(Ji jyuu)=3674kg and Take off(Seiki)=5700kg.
However, range section tell us more information.
There are three loading/range values.
It says that 5700kg/1000nmile when take off condition(Seiki), 6390kg/1640nm when loading(ka kajyuu) and 6590kg/1610nm when torpedo loading.
From range value, we can know take off condition doesn't mean 100% of fuel .
So we must predict FM's take off weight from torpedo loading weight(no information about content when loading condition).


Sorry, FM's take off value will be maximum take off value that is reference to determine the envelope of flight.

When a historical weight parameter was tried, the takeoff from an aircraft carrier was difficult for me.
Therefore, the parameter was adjusted and released.
Possibly weight was too light.  :P

I understand the acceleration problem when using high power engine.
Then why don't you adjust Reductor value?
Other high hp engine also seems adjusted by reductor.
Maybe, there is reason that weight affect maneuver more than reductor(~ affect traction by prop.) by dividing square terms(1/2[rho]sv^2c) or problem when low-mid reductor value in FM.
