Weapon firing effects for coaxial machinegun appear in the wrong place

So I am trying to improve a port I did of a Vodnik from Arma 2, and the main 30mm gun works fine, and has the smoke and light effect at the end of the barel, as it should be: However, the coax machinegun effects appear in the wrong place. The muzzle flash is right, the tracers show the rounds are coming out at the right place, but the smoke and the light effects are wrong: I have a similar problem with a further modified version of the Vodnik in which I have scaled down the 30mm barrel, and duplicated and rotated it to look like a gatling gun (and I have changed the animation so the barrels rotate when firing), I made a new weapon class for it based on an HMG (but now with a much higher ROF and muzzle , and lead prediction so its an effective light AA gun). What do I need to do to define where these effects appear for each weapon?

Hmm this 50m limit from center I am afraid too - but will make experiment with single turret model alone and will see, also I will test on vanilla turret adding my wepon to this turret and check if problem will ocure - or add it to tank turret - mechanic should be the same so problem source will be divided to weapon or turret config. I made a test with only turret model < 50m size, still the same problem but something must be in model config or model beacouse test with tank and vanilla turret make on weapon positive state (weapon working corectly on other vehicles so config of ship/turret is problematic). Seems to be a problem in model.cfg definitions but what could cause this kind of issue ( I make test on problematic turret with other weapons like grenade luncher or other canno type and still no effect on ammo but clouds and fire effects are made in correct place and in correct direction WTF? I am close and close to solve problem on RTP I found : Error: bin\config.bin/CfgVehicles/HWK_MK45/Turrets/Mainturret/: Turret body MainTurret not found while initializing the model hwk_mk45\hwk_mk45_gun.p3d
Error: bin\config.bin/CfgVehicles/HWK_MK45/Turrets/Mainturret/: Turret gun MainGun not found while initializing the model hwk_mk45\hwk_mk45_gun.p3d I made turret class as new turret but what is missing in this?: class NewTurret;
       class Turrets {
class Mainturret: NewTurret {
           class turrets {};
           class Reflectors {};
           aggregateReflectors[] = {};
gun = "MainGun";
                   animationSourceGun = "Maingun";
                   body = "MainTurret";
                   animationSourceBody = "MainTurret"; ........................ };
         }; SOLVED: in model.cfg animation class name must be the same as declared as body and gun in turret class (those names are not bones of model but clases of animations of those bones - crazy as usually) - now turret config is like that:     gun = "gun_elev";
                   animationSourceGun = "Maingun";
                   body = "turret_turn";
                   animationSourceBody = "MainTurret"; due to model animanames: class turret_turn
           {
               type="rotation";
               source="MainTurret";
               selection="turret";
               axis="axis_turret";
               //animPeriod = 10.6;
               memory=1;
               minValue="(rad -360)";
               maxValue="(rad 360)";
               angle0="(rad -360)";
               angle1="(rad 360)";
           };            class gun_elev:turret_turn
           {
               source="Maingun";
               selection="gun";
               axis="axis_gun";
           };
