F4U DevGru - Check This Decimal Point

F4U DevGru - Check This Decimal Point

Pitch in the F4U was massless and twitchy, not so for Roll.

Looked at the 'F4U-1D.lua' file, and came across this in the 'SFM'.

894            kjx = 2.25,
895            kjz = 0.00125,

Guessed Roll and Pitch Inertia, respectively, as that's about like how they act.

So moved the decimal point on kjz to:

894            kjx = 2.25,
895            kjz = 1.25,

Flies like a regular airplane now, with mass and rotational inertia in pitch as well as roll, in a proper proportion.

My biggest FM gripe, as it was untenable, in the face of the F4U's reputation as an outstanding gun platform.

Found that 'kjz = 1.25,' was dragging the nose around a bit in yaw, so went back to the initial gambit of '+1', in this case a 25% reduction from that previous setting.

Moved the decimal point back on kjz, and then added "1":

894            kjx = 2.25,
895            kjz = 1.00125,

Much nicer in yaw, and just a bit more sensitive in pitch, but the Inertia is still there.

Set the 'X' and 'Y' joystick curves from 19 to '21' both.

Really flies nice, and a good gun platform at boot.
