You don't have to saw it off. You can use 2 pipe wrenches and unscrew that pipe out of valve unit. ...


Or, don't saw it or unscrew it. Just unscrew the air mixer (the last 2" or so of the torch head). Then use a short piece of pressure hose and a pair of hose clamps.

Advantages;
1. The orifice at the tip of the fuel pipe makes it nearly impossible to get liquid propane into the meter.
2. You can easily reassemble the the torch head and have a working (and safe) Bernzomatic torch.

I am sure your mom wont give you
money for that hobby because it's VERY expensive.

(an good rc copter(as my father one) cost 600 $(without talking of crash fee's)).

And it's a lot of pain in your ass to make it(my dad taked 2-3 months and he is an engineer.)

And you probably dont have the skill needed. :roll:

Mondo expensive if you get into the nice ones. Don't start out with a really nice one...You WILL crash it several times learning how to fly it.
