Optimus Crux Stove
The ridiculously tiny Optimus Crux Stove folds up to fit under a 220g butane canister and weighs only 3.3oz. When you need to go ultralight on your backcountry travels, this stove definitely needs to be with you. The Cruz Stove burns for 60 minutes going full blast with a 220g canister, and it boils a liter of water in only 3 minutes. When you decided to bring a tarp instead of a tent and pull the frame from your pack to save weight, you better have this Optimus stove on the gear list.
Bottom Line: Stoves just keep getting lighter and smaller, and Optimus is at the head of the pack with the 3.3oz Crux Stove.

The five main things I like about this stove is:
1. 12,000 BTU's,
2. The way it folds down & fits into the bottom of your fuel canister,
3. Very lightweight,
4. Constructed of high quality components for durability & longevity,
5. Fuel efficient. Uses 5g of fuel to bring 8oz of water to boil.
If you're a stove nut like me, this is a must have for your collection.

I love this stove. very light very compact. I fit it inside my msr titan cup along with my brunton spork and a lighter.

Is this the same as the Brunton Flex with the exception if the folding arms?

It is basically just Bruntons version of the crux. I havnt used the Brunton before but apparently the Brunton is supposed to be a little better at simmering. I had the crux (until I lost it) and it was a good little stove. A little unstable which I think the Brunton fixes with the 4 pot supports. Hope that helps.

Better than my stove at home

This stove works great. Folds down so small and fits under the canister inside my cookset (Optimus Weekendeder). The "stuff sack" it comes with does not nestle inside my cookset, so I just keep it form bouncing around with a microfiber camp towel. It will boil a liter of water in 3-4 minutes, and I got 6 boils out of a 220g canister in moderate temperature, 60F, with little wind. I can blow it out myself, so I would recommend a wind screen if you will be relying on this stove for all your cooking. Temperature control works well for me and I am able to cook fresh eggs for breakfast without any burning. The folding arms do tend to become harder to open/close after their slight warping during normal use, but I actually prefer this since they wouldn't stay closed during transportation before it was used. The Optimus Crux does boil water faster than the Frigidaire appliance I have sitting in my kitchen at home. I highly recommend this stove.
Tiny and efficient.

Almost disappears in your pack it is so small, my only complaint is the extending arms got very stiff after the first use.

Write your question here... I own this stove and it is having some issues. I atttach it to the gas canister and turn the valve and nothing happens. I have hooked the same gas can to my MSR reactor and it works fine. I am wondering if I need to buy some repalcemnt parts or what. I have not used the stove for a really long time, but only used it once. What do you recommend i do. it is a nice stove just dones't have any gas flow.

I've never had any problems with my Crux so I'm trying to trouble shoot your stove.
Make sure the the base, male extension, of the fuel tube is intact. This is where it penetrates the canister & opens the canister's Lindal valve to receive the gas. If it is bent or broken, you'll unfortunately have to replace your stove.
Remove the rubber o-ring & inspect it carefully. Make sure it is pliable & doesn't have any cracks. Replace it if you see anything suspect. Return it to it's proper position.
Make sure the fuel chamber @ the metal ring locking mechanism, in the folding position is clear & unobstructed. Fold & unfold the stove a number of times to get a positive "click" & make sure the metal ring moves all the way back up & locks in place.
Change fuel canisters.
Hopefully something above will fix your problem.

Can't beat the price and size

Just got this stove and have yet to field test it but so far I think it will do. Pros: tiny, you can fit this thing just about anywhere, doesn't quite fit under the 220 as well as I would like and will probly just thow it on top of the canister in my pot. The flame adjustment is great. Unlike others who say it is hard to adjust I would disagree, you can easily get this thing to simmer. Cons: no need to wast the time and ounces with the included carry case, top seems to be a bit wobbly and unstable, something I may be able to remedy with a quick tightening or whatnot, certainly not something I would leave unattended. Overall I am pretty happy with it. I'm guessing it will serve its purpose and be a part of my gear for a long time to come.
Needs some fixes

Sure is light and nifty, but the folding burner does not lock properly and I spilled a liter of boiling water the first time I used it. No harm done, but if you do this on a small bivvy ledge you could end up with it in your lap! Too bad, because its bad engineering, not a bad concept. The valve is sooooper touchy! It seemed like unless you had it cranked up like a Saturn V (am I dating myself?) you could not touch the valve without the stove flaming out instantly. Don't know what the cause of that is, but it's not something that happens on the any of the other half dozen stoves I own. I took it back to MEC and they gave me refund! Optimus needs to fix the wobble, or they'll have liability issues!
