Question about plane engine stats in Physics.con

[dudejo]

I've been playing with the different stats on airplanes to give them more realistic performance.

So I ask, what's the real-life equivalent to setDifferential for airplanes? Are propellers only as fast as the engine rotates?

[freddy]

if i want a pco to go faster i usually raise the setDifferential value on the engine, however the engine will always stop accelerating when the setNoPropellerEffectAtSpeed limit is met. for planes its usually 70 but as you surely know you can reach higher speed then that by diving and let the gravity accelerate you (usually get around 125 max by gravity if i remember right)

only thing you can do is do some experiments which is wasting lots of time..
The setting that affect your plane performance also have accelerate, max rotation, min rotation, torque, max speed etc..
Also your mass, the coefficient, inertia blah blah blah..
So, i suggest you try out from torque accelerate and max speed first.

[dudejo]

Aren't those acceleration/maxspeed/etc stats merely for engine momentum?

Also, I pretty much learned how Mass and Drag work from working with land vehicles.

It's the meaning of Differential for planes I'm hunting for. What about the plane's rotor size?
