Hi there forum!
I really like the C130J in ArmA2, although there is a small problem with it. I really like to land the C130J in fields and the open areas in the forest. I can do a landing in about 400m give or take but 400m isn't near enough to start when it's a bit bumpy. Now I have searched the forum and all over the web and maybe it's because I'm a newbeginner. Maybe I'm not using the right search terms and I'm sorry if it seems obvious to you but that's why I'm asking you.
One thing that would make it work would be if there existed a C130J "JATO" Scipt that could give the C130 a huge boost to get it up in the air. Is there such a script or can it easily be made?

I also noticed its very hard to take of even from unpaved runway in the south or Chernarus this is almost impossible due to some trees at end of the runway. Sinds there is no wheel brake on the plane you cannot let the engine make power before starting to roll, i think this is how they do it in real life. Idd also love to see a proper solution for this.
On of the people of the DAFmod team is currently making a wheel brake for an F16 maybe we can also use this on the C130! Thanks for pointing towards this problem!

Indeed. The wheel brake action would help a lot. Now I do not know much about scripting in ArmA2 but this seems like something that's not too hard to make. Hell, I would buy a cup of coffe to the fellow who could make this! Added 21 hours 25 minutes later:
It's a more "JATO/Booster" solution where the script gives x amount of boost until speed y is achieved. Sadly, I have yet to find a script to brake the wheels but in the mean time, this'll do. I will try this one out and post results here.

Hi there - what a coincidence, I just made myself a JATO script a week ago.
It was necessary for a mission where I wanted to be able to take off from balota with a C160 Transall.
I will adapt it for the C130 and try polish it a bit more. The boosting part of my script isn't as sophisticated as described in your link above fnadde42, but mine got some fire and smoke : )

Well Gentlemen, first of all, good idea to initiate this project! But to be honest, partly this is due to pilot proficiency. All airfields in Chernarus are serviceable with the C-130 in all directions of take-off. The trick is to get up to ca. 140 kph a.s.a.p. and rotate to about 5 degrees nose up. After your wheels leave the ground, your airspeed will climb sufficiently to continue the nose up pull and the climb over any obstacle. In sum, the trick is not to wait for the regular rotation speed, but pull off the ground early - giving your plane opportunity to accelerate in air. Flaps help the climb, but slow the acceleration on the ground, so use them late.

Anyway I had it made already and I wanted to set it up for the C130 too, glad there's other people who might profit from it.
You need to make 2 textfiles in your mission folder, 1st called jato.sqf, the 2nd jatoaction.sqf

put this in the init line of your aircraft:
nul = [this] execVM "jato.sqf"
or even better: use a trigger. This will allow you to easily reload the JATO System.
Make a trigger, set it to <Activation Bluefor, Present, Repeatedly> and put this in its <Condition> line:
{typeof _x == "C130J"} count thislist >0
Adjust the type of C130 you are using.
In its <On Act> field put this:
_xhandle = [(thislist select 0)] execVM "jato.sqf"; hint "JATO ready";

to use it you could simply put nul = [this] execVM "jato.sqf" in the planes init line.
I prefer a trigger so you can reload the JATO system and it will also work with respawned vehicles.
Make a trigger, set it to <Activation Bluefor, Present, Repeatedly> and put this in its <Condition> line and Adjust the type of C130 you are using:
{typeof _x == "C130J"} count thislist >0
and in its <On Act> field put this:
_xhandle = [(thislist select 0)] execVM "jato.sqf"; hint "JATO ready";
Have fun
Edit: updated Code slightly, should work in MP and SP.

While researching this Rocket Launch thing i came across a C130 Version called Credible Sport.
So I simply had to make a very crude version of the reverse thing.
Since I'm not a professional don't expect too much, but it looks fun at night time
replace the jato.sqf code with this
/*-------------------------------------------------------------------

All of the above and this were tested in multiplayer environment.
If 1 player and 1 AI use it at the same time it can get messy. I am not sure how to fix this reliably yet. Not 100% sure what happens if 2 players use it at the same time in it's current state.
Also works in single player as far as i can tell.
Let me know what you think of it,
