Change Speed of Aircrafts?

Hey guys,

 

I have been playing around with the handling.meta file and have been able to change land vehicle's acceleration and top speed successfully by editing fInitialDriveForce and fInitialDriveMaxFlatVel values. I noticed that air vehicles also have these values, but changing them seem to have no effect on the vehicle's performance for some reason. I also tried changing the Thrust values to no avail.

 

So, how can you change the acceleration and top speed of air vehicles?

 

Thanks

Has no one figured this out yet? I don't see any released mods out yet that changes this yet...

I tested with the Lazer and made some interesting discoveries.

 

Changing the drag, maxvel, force, and thrust to rediculous amounts makes it accelerate crazy fast (Standstill to flying with one click, quite annoying actually)

 

There are speed limits at certain altitudes, 192mph at sea level getting up to around 250mph I believe at high altitude. The only way to surpass these is to fly down to gain speed but no matter how fast your plane is you cant exceed these speeds normally.

 

The 747's in the air fly at around 190mph even though if you fly it yourself they can only get up to 130-140

 

Landing an insanely powerful Lazer is essentially impossible

 

So in conclusion, until someone finds a way around this you can only make them minimally faster.

 

Ref: Here is the handling I made (only use it for testing, it makes the lazer useless for anything other than going at max speed)

Looks good, Brendon any chance you change some of these values:

 

<fDriveInertia value="3.000000" /> to 2.850000

<fBrakeForce value="0.050000" /> to 0.065000
<fBrakeBiasFront value="0.600000" /> to 0.650000
<fGearDownDragV value="0.100000" /> to 0.225000 (should slow the aircraft down when the gear is down)

The handling isn't meant to be a good handling, just to test what the maximums are. My plan was to find the maximum and then work out the best/most realistic way to get to it. But since the maximum was so low I didn't bother.

Ah fair enough no problem thanks for your efforts anyway!

Yea I noticed this as well. It seems like there is some kind of overall physics speed limit in place for any air vehicle. Wonder if there is anyway to get around that; so far all my attempts have not worked.

Yeah, R* always uses an aircraft speed limiter in their games. Based on the handling data, the planes should be able to go faster without even editing. Somebody has to figure out a way to turn off the limiter, and especially the jets will automatically go much faster(top speed).

I think the answer may lay in some of those trainers out there. I just noticed when using the Native Trainer's speed boost option that you can make any vehicle including aircraft accelerate to a high speed quickly, in this case 358MPH. So, maybe someone who knows how to code trainers can enlighten us perhaps?

The problem is 360mph is the limit for everything (cars, boats, and planes), using the handling I made and flying straight down you can get to 360mph (even if you level off) but even that isn't really fast enough... The lazer IRL should go in excess of 1000mph. I understand that is crazy fast for gta but it should be at least 500-750mph to make it worth bothering with it.

Yea, after some more testing myself, that seems to be the case; no vehicle can exceed 358MPH. This is probally a hard coded limit in the physics engine for stability reasons. I'm guessing its just not something we can change at this point unfortunatly.

I think I might of found a way to at least get full speed at lower altitudes, but I need to reverse thrust when the brake is applied. Anyone know how to triger reverse thrust when the brake is applied for aircraft?

GTA 4 compared to GTA 5 had just 288 KMH speed limit, be glad it's not the same in GTA 5.

Wow so nothing can go faster than 358mph? I'm not complaining as that is damn fast.

 

So, when I change the max speed of a car in handling.meta, is the number I'm entering kph or mph? I'm guessing kph. 568mph = 576.14kph.

It's in kph. Simply changing all the cars max speed to the real numbers (As I have personally done), you can get them to go significantly faster. I can get the Entity XF up to 200mph with max upgrades (without franklin or hills).

I believe maximum speed is limited by the game engine, at least it was in IV so probably the same in V.

As part of my mod I just released, I made all aircraft as realistic speed as possible. The jets can now reach the full 358mph with controllable handling. The only issue is that after hitting top speed you can't slow down unless you decline to a low altitude, but other than that the handling is similar to default. My mod changes all vehicles performance and I was able to get all other vehicle types including helicopters to realistic numbers. You guys can check it our here if interested...

Can the files be used for playing GTA Online or would the speed difference be that noticeable?

About the game limit - funny story last night... some guy was driving a train at speeds (he claimed) were in excess of 900km/h, and eventually got over 1200.
I was at full pack in the Hydra and the train went past as if I was moving backwards. Granted that may have only been at around the 200mph mark but the train was easily several times faster. So whoever created that mod must know how to get around the game's limits, unless it's just different for trains (eg no limit)?

Most likely it's different for trains since they aren't a normal vehicle. Train mod crashes my game so I can't test
