The Helimax gauge is pretty good, a paddle gauge might not hurt, and if you have carbon blades, you can probably wait on the balancer. Magnum fuel is usuallly 5.00 a gallon cheaper than cool power and is real good fuel. If your homeade allen starter does not have a ball tip on it already, it might be a good idea to grind it that way so you can be at a slight angle with no extra pressure to the starter socket.
