Grenade on UDKProjectile

[Demestotenes]

A falling grenade projectile works on UTProjectile but not on UDKProjectile.
What needs to be done to make UDKProjectile fall?

UTProj_Grenade:

defaultproperties
{
	ProjFlightTemplate=ParticleSystem'WP_RocketLauncher.Effects.P_WP_RocketLauncher_Smoke_Trail'

	ProjExplosionTemplate=ParticleSystem'WP_RocketLauncher.Effects.P_WP_RocketLauncher_RocketExplosion'
	ExplosionLightClass=class'UTGame.UTRocketExplosionLight'

	speed=700
	MaxSpeed=1000.0
	Damage=100.0
	DamageRadius=200
	MomentumTransfer=50000
	MyDamageType=class'UTDmgType_Grenade'
	LifeSpan=0.0
	ExplosionSound=SoundCue'A_Weapon_RocketLauncher.Cue.A_Weapon_RL_Impact_Cue'
	ExplosionDecal=MaterialInstanceTimeVarying'WP_RocketLauncher.Decals.MITV_WP_RocketLauncher_Impact_Decal01'
	DecalWidth=128.0
	DecalHeight=128.0
	bCollideWorld=true
	bBounce=true
	TossZ=+245.0
	Physics=PHYS_Falling
	CheckRadius=36.0

	ImpactSound=SoundCue'A_Weapon_RocketLauncher.Cue.A_Weapon_RL_GrenadeFloor_Cue'

	bNetTemporary=False
	bWaitForEffects=false

	CustomGravityScaling=0.5
}

CustomGravityScaling is declared in UDKProjectile.
But when i put those defaultproperties to a class extended from UDKProjectile, it will not move, even when i manually set its velocity ( Velocity = dir * Speed )
Probably UDKProjectile does not move with PHYS_Falling (or is it something else?)

Has anyone successfully made a falling projectile on UDKProjectile?
I would be thankful for help.

When i set the physics to PHYS_Projectile and then set Acceleration, it will fall.
However, the acceleration is not replicated to clients.
Should i add a replication block with 'Acceleration'?

The only real difference I can see between your Def. Properties and mine is.

bBlockedByInstigator=false
TerminalVelocity=3500.0

And yes, I have a working Grenade and all my projectiles are based on UDKProjectile.

Thx very much for help.
Now it falls correctly.
Your lines are added in UTProjectile, so UTProj_Grenade inherits them and i didnt see them.
