Custom armor rendering

Hey guys,

i got a problem with the custom armor renderer.

the helmet and legs works fine but the rotations of the body are a little off when aiming a bow, blocking with a sword and hitting.

this is my model code:

public class ModelDragonPlate extends ModelBiped{

public static final ResourceLocation texture = new ResourceLocation(Reference.MOD_ID, "textures/armor/dragon_plate.png");

ModelRenderer shoulderL;
ModelRenderer hornL1;
ModelRenderer hornL2;
ModelRenderer shoulderR;
ModelRenderer hornR1;
ModelRenderer hornR2;
ModelRenderer braceL;
ModelRenderer braceR;

public ModelDragonPlate(){
	textureWidth = 64;
	textureHeight = 32;

	shoulderL = new ModelRenderer(this, 0, 0);
	shoulderL.addBox(-1.5F, -2.5F, -2.5F, 5, 5, 5);
	shoulderL.setRotationPoint(5F, 2F, 0F);
	shoulderL.setTextureSize(64, 32);
	setRotation(shoulderL, 0F, 0F, 0F);
	shoulderL.mirror = false;
	hornL1 = new ModelRenderer(this, 0, 0);
	hornL1.addBox(3F, -4F, 0.5F, 1, 3, 1);
	hornL1.setRotationPoint(5F, 2F, 0F);
	hornL1.setTextureSize(64, 32);
	hornL1.mirror = true;
	setRotation(hornL1, 0F, 0F, 0F);
	hornL2 = new ModelRenderer(this, 0, 0);
	hornL2.addBox(3F, -4F, -1.5F, 1, 3, 1);
	hornL2.setRotationPoint(5F, 2F, 0F);
	hornL2.setTextureSize(64, 32);
	hornL2.mirror = true;
	setRotation(hornL2, 0F, 0F, 0F);
	shoulderR = new ModelRenderer(this, 0, 0);
	shoulderR.addBox(-3.5F, -2.5F, -2.5F, 5, 5, 5);
	shoulderR.setRotationPoint(-5F, 2F, 0F);
	shoulderR.setTextureSize(64, 32);
	shoulderR.mirror = true;
	setRotation(shoulderR, 0F, 0F, 0F);
	hornR1 = new ModelRenderer(this, 0, 0);
	hornR1.addBox(-4F, -4F, 0.5F, 1, 3, 1);
	hornR1.setRotationPoint(-5F, 2F, 0F);
	hornR1.setTextureSize(64, 32);
	setRotation(hornR1, 0F, 0F, 0F);
	hornR1.mirror = false;
	hornR2 = new ModelRenderer(this, 0, 0);
	hornR2.addBox(-4F, -4F, -1.5F, 1, 3, 1);
	hornR2.setRotationPoint(-5F, 2F, 0F);
	hornR2.setTextureSize(64, 32);
	setRotation(hornR2, 0F, 0F, 0F);
	hornR2.mirror = false;
	braceL = new ModelRenderer(this, 0, 10);
	braceL.addBox(-1.5F, 5F, -2.5F, 5, 1, 5);
	braceL.setRotationPoint(5F, 2F, 0F);
	braceL.setTextureSize(64, 32);
	braceL.mirror = true;
	setRotation(braceL, 0F, 0F, 0F);
	braceR = new ModelRenderer(this, 0, 10);
	braceR.addBox(-3.5F, 5F, -2.5F, 5, 1, 5);
	braceR.setRotationPoint(-5F, 2F, 0F);
	braceR.setTextureSize(64, 32);
	setRotation(braceR, 0F, 0F, 0F);
	braceR.mirror = false;
}

public void render(Entity entity, float f, float f1, float f2, float f3, float f4, float f5){
	setRotationAngles(f, f1, f2, f3, f4, f5, entity);

	GL11.glPushMatrix();
	TextureHandler.instance.bindTexture(texture);

	shoulderL.render(f5);
	hornL1.render(f5);
	hornL2.render(f5);
	shoulderR.render(f5);
	hornR1.render(f5);
	hornR2.render(f5);
	braceL.render(f5);
	braceR.render(f5);

	GL11.glPopMatrix();
}

private void setRotation(ModelRenderer model, float x, float y, float z){

	model.rotateAngleX = x;
	model.rotateAngleY = y;
	model.rotateAngleZ = z;
}

public void setRotationAngles(float f, float f1, float f2, float f3, float f4, float f5, Entity entity){

	EntityLivingBase living = (EntityLivingBase) entity;

	ItemStack itemstack = living.getHeldItem();

	this.heldItemRight = living.getHeldItem() == null ? 0 : 1;

	if(living instanceof EntityPlayer){

		EntityPlayer player = (EntityPlayer) living;

		if (living.getHeldItem() != null && player.getItemInUseCount() > 0)
		{
			EnumAction enumaction = itemstack.getItemUseAction();

			if (enumaction == EnumAction.block)
			{
				heldItemRight = 3;
			}
			else if (enumaction == EnumAction.bow)
			{
				this.aimedBow = true;
			}
		}
	}

	super.setRotationAngles(f, f1, f2, f3, f4, f5, entity);


	shoulderL.rotateAngleX = bipedLeftArm.rotateAngleX;
	if (this.heldItemLeft != 0){
		shoulderL.rotateAngleX = this.bipedLeftArm.rotateAngleX * 0.5F - ((float)Math.PI / 10F) * (float)this.heldItemLeft;
	}
	shoulderL.rotateAngleY = bipedLeftArm.rotateAngleY;
	shoulderL.rotateAngleZ = bipedLeftArm.rotateAngleZ;
	hornL1.rotateAngleX = shoulderL.rotateAngleX;
	hornL1.rotateAngleY = shoulderL.rotateAngleY;
	hornL1.rotateAngleZ = shoulderL.rotateAngleZ;
	hornL2.rotateAngleX = shoulderL.rotateAngleX;
	hornL2.rotateAngleY = shoulderL.rotateAngleY;
	hornL2.rotateAngleZ = shoulderL.rotateAngleZ;
	braceL.rotateAngleX = shoulderL.rotateAngleX;
	braceL.rotateAngleY = shoulderL.rotateAngleY;
	braceL.rotateAngleZ = shoulderL.rotateAngleZ;

	shoulderR.rotateAngleX = bipedRightArm.rotateAngleX;
	if (this.heldItemRight != 0){
		shoulderR.rotateAngleX = this.bipedRightArm.rotateAngleX * 0.5F - ((float)Math.PI / 10F) * (float)this.heldItemRight;
	}
	shoulderR.rotateAngleY = bipedRightArm.rotateAngleY;
	shoulderR.rotateAngleZ = bipedRightArm.rotateAngleZ;
	hornR1.rotateAngleX = shoulderR.rotateAngleX;
	hornR1.rotateAngleY = shoulderR.rotateAngleY;
	hornR1.rotateAngleZ = shoulderR.rotateAngleZ;
	hornR2.rotateAngleX = shoulderR.rotateAngleX;
	hornR2.rotateAngleY = shoulderR.rotateAngleY;
	hornR2.rotateAngleZ = shoulderR.rotateAngleZ;
	braceR.rotateAngleX = shoulderR.rotateAngleX;
	braceR.rotateAngleY = shoulderR.rotateAngleY;
	braceR.rotateAngleZ = shoulderR.rotateAngleZ;

	this.aimedBow = false;
}

anyone knows how to fix this?
