I quite like the Heavy Flamers! The ones that came in the weapons packs were a bit insubstantial, so i just chopped off the ends and handles on a lasgun and stuck a flamer barrel on the end! It just bulked out the weapon a bit, and also made for a very easy conversion!! The fuel lines are some fine wire twisted together, easy
The green stuff should be dry by tonight, so I'll get the undercoat on them later!
