Fire Maple Petrel Ultralight Pot

Thanks Brad, these seem like common complaints for the BRS.

Every time I think about picking up a BRS, its a hard sell:

BRS (0.9 oz/janky)->Stash Ti stove (2oz, semi-janky: quality good, cold/wind not)->PRD/Soto (3oz, solid)

Interested in the details of your windscreen when it’s ready.  Here’s my DIY wind shield you might find interesting:  10g, pretty quick set up, stores in pot.  Its cheap and easy to make from common materials.  A couple years in, I’m happy with it.  Only change I made was to solder the copper arms together where they wrap over the stove’s arms, so they can’t work loose

Issues withthe BRS 3000t

If it works, it works,  There were some start and batch quality issues, but when it works, it works (in calm conditions).

Of course, it is sensative to the wind, that is well demonstrated.

What isn’t commonly reported are thermal issues and in reality few people will experience this. The BRS tends to work fine if your boiling 2 cups of water.  When heating large volumes of water, the valve body gets quite hot to the point where you cannot comfortably put your fingers on it.  This has to do with the extremely short body length, the burner to canister distance as well as not having a large thermal break between the burner and the canister threads.  Probably a really bad stove for snow melting.

An additional thermal issues are long simmering/baking times.  When run for a long period of time (+30 minutes) at a low level, the stove body also gets extremely hot.  My 2 cents.

Thanks, Jon.

Without a screen, it’s pretty sad.  Below from Gear skeptic.  The Stash+PRD uses 60% the fuel at just 1mph and less than half at 2 mph

Some differences from Jon’s results, not sure why:

There are some set up differences between My results and Gearskeptics

1)      I use a wind tunnel that draws smoothly across the cooking system, and he uses a fan which has some vortices.

2)      I heat water up to a boils and he doesn’t

But at the end of the day, the results are pretty comparable.  I’ve gone through the math to system fuel efficiencies and scaled the results to compare and they are within a few percent of each other.

David, here’s the little Ti foil “tube windscreen” I made for the BRS. It’s a 17mm tall tube that sticks 13mm above the burner head. Weigh’s 0.2g’s. I ran a couple boils with it this afternoon using the Petrel G3 pot.

No Wind & Without Windscreen:

BRS using the Fire Maple G3 Pot (sitting in the slots) on Low setting brought 500ML of water to a boil (5,010′ elev / 61*F H2O / 72*F Air Temp) in 7:30 @ 4.7 g fuel used.

5 MPH Wind With Windscreen:

BRS using the Fire Maple G3 Pot (sitting in the slots) on High setting brought 500ML of water to a boil (5,010′ elev / 61*F H2O / 72*F Air Temp) in 9:00 @ 15.6 g fuel used.

I could definitely smell unburned fuel with the wind test lol. So while it allowed the BRS to remain lit in a 5mph wind, I wouldn’t consider it a very successful design. Perhaps a few holes in the Ti down low on the tube would help.

I should probably run the BRS with the windscreen on low, without any wind, and see how it compares to the no windscreen / no wind test which burned 4.7g’s fuel. It would indicate how much fuel is wasted by an inefficient burn from the screen design.

The BRS w/ windscreen tube and the G3 pot bested Jon’s Ocelot Mini / Toaks 95 test by 1g (not an apples-apples test obviously as the G3 is an HX pot). Not earth shattering, and probably within the margin of error. But again, Jon’s tests are more accurate being essentially “lab” conditions. As he rightly points out, using a fan like I do creates vortices. But, it’s close enough for hand grenades I suppose. Either way, it confirms why I consider the BRS “Janky” lol.

It’s the other way around: The G2 is 750 ml, 126 mm diameter, and 184 g.

G3 is 600 ml, 102 mm diameter, and 162 g.

Edit: This was in reply to Matt’s post.

LOL.  Maybe flame quenching?  Was the flame red instead of blue?  How many times did the house CO detector go ballistic?  :)   0.2g would be sweet but I’ve never seen a commercial stove do this (scratches head)

I didn’t slot my Stash for the PRD because Jet Boil’s design with the Ti stove already creates a larger gap.  Only thing I could think of was to minimize flame quenching
