Im going HB so I need to take apart the bottle and Im not entirely sure how I take the maxflow off from the bottle. And Im not going to attempt it because knowing me Ill end up blowing myself up.
was it fitted to a bottle when you brought it. The few i've seen i managed to unscrew by hand the others i've used a couple of strap tools to remove them
Sure you need to take the reg off mate? Is it just for the flight or another reason? Flying is usually fine with the reg on if that is the case though you might need to check with the specific airline.
