Thread: A question about pitch, yaw and roll numbers

I have been looking for this info in a post but I can't find it.

What do those numbers for pitch, yaw and roll actually mean?

For example: TIE-Interceptor: Spdx 1.0 Acc 40 Dec 60 Pitch 300 Yaw 300 Roll 150

I have an engine that has pitch, yaw and roll in the 50s and an engine that has pitch, yaw and roll in the 60s. When I put them in my Interceptor I get the same numbers for pitch yaw and roll acceleration when I look under "V" when I am flying in space. They are: 5.2, 5.2 and 2.6.

The only number in the "V" window that is different is the number for pitch (max), yaw (max) and roll (max) that shows as 1 for the engine in the 50s and 1.1 for the one in the 60s.

I have noticed that most crafted engines have those numbers in the 50s.

I guess my questions are what are those max numbers from the "V" window, what do the pitch yaw and roll numbers from the faq actually do and which engine is better?

Thanks

Good question, I've wondered myself. I believe the number you see changing, the 1.0, 1.1, 1.2 ect. is the modifier to the unchanging number. With the 50'sPYR engine your PYR is 1.0x5.2, 1.0x5.2, 1.0x2.6. With your 60'sPYR engine they are 1.1x5.2, 1.1x5.2, and 1.1x2.6. I think.


To add to this question, can anyone tell me at what PYR engine stats does the modifier (1.1, 1.2, etc.) increase? I've read in one of the pilot threads that to get the 1.3 modifier you need an engine that has 71.xPYR. I'm curious if this changes per ship based on the PYR(300/300/150) of the ship or if it is simply based on the PYR(60/60/58) of an engine.


This would help in crafting those uber engines. If I know what PYR to shoot for for the best modifier (1.1, 1.2 or 1.3) I can just reach that PYR on the engine then put the max into speed I can instead of pushing the PYR higher with no real benifit to the handling of the ship.

The speed index represents the fraction of an engine's speed that the chassis will allow. For example, if the speed index is 0.9 and the top speed of the equipped engine is 102.4, then the top speed of your ship will be the top speed multiplied by the speed index times 10, which is 922.


Noone has been able to tell me how they determined the acceleration and deceleration figures.


The YPR you see posted on the forums is the rotational acceleration in radians/second/second, which has NOTHING to do with the YPR stats on your engine. The YPR stats on your engine represent the maximum rotational speed in degrees/second (if I'm not mistaken).

Chassis is acceleration to until you reach the max rotational speed. YPR numbers on engine are the Max rotational speed.


Chassis=radians per second squared...ie rotational accleration


Engine=radians per second....ie rotational velocity

Yes, engine stats specify rotational velocity, but not in radians/sec. Engine stats are specified in degrees/sec. Think about it for a minute, a radian is about 57 degrees. If you could rotate on any axis at say 60 (the engine stat) multiplied by 57 degrees, you'd be very dizzy.

Heh, good point, yea must be degree's per second.

In fact, I believe I made a mistake as well. I believe the acceleration stats specified on the forums for chassis are stated in tenths of radians per second per second (I stated earlier that it is radians/sec/sec).
