    I been getting lots of pms asking for pictures of comparisons between these cooksets and others. Instead of pming pictures I decided to post this comparison thread. I’m doing another right after this. If you got questions post it here. Thanks and I hope these pictures help.
    Left is the Trangia Duossal 27 kit and right is the Optimus 81 trapper I posted herehttps://bushcraftusa.com/forum/threads/optimus-81-trapper-alcohol-cook-system-“picture-heavy-thread”.248007/ B289C595-BBA5-4645-8D87-8096DBC1BE67.jpeg 04D6F347-CFDF-44B7-8ABF-DE9F0F90B34D.jpeg 57326763-A9F6-4D07-A3EB-45B3342CB436.jpeg 41CAA10F-2859-4A98-A99F-74C6118CD7CD.jpeg 58416D08-A7BD-48C0-B210-FA7D38C4DA6C.jpeg DAA97C5F-EF40-423B-AEDB-05ED9B195C21.jpeg 0E1486B9-D7FC-4A4C-A400-006B3DF141CA.jpeg

    Optimus 81 above all the others. If I could only have one alcohol cook system the trapper be it!
    Both my Duossal 27 & 25 are great but I rarely use them. I actually plan on putting my Optimus 11 explorer in one of the duossal kits but never got around to it.

    I like the air flow of the 27 & 25. Hugs the sides of pot and pans. My conversions to esbit has been working nicely. My
    DIY alcohol burners work nicely.

    I agree. All these kits have great gear exchanging qualities.

    Does the Optimus windshield/pot support have a twist-lock feature that secures it to the base?

    No it’s just s snug fit. It base has a ring and the windshield sits perfectly in that ring. Imaging a telescoping pole. The inner and outer rings is how it fits. On the cheap clone it’s very lose fitting but the Optimus you can press down on one side and it won’t top of come apart. The clone does. But there’s ways to make it interlocking. It can easily be modified to lock on similar to the trangia. Personally I like the older trangia sets where the windscreen didn’t lock on.

    This Optimus 81 trapper is coming into my next rotation of stoves to use. I’ll post pictures as I use it!

    I have a few stoves laying around that are either missing parts or is working and just not in use. While looking at an adapter I have I had a thought it might fit in the Trangia 25 & Trangia 27 storm cookers. Fits I. The 25 easy but I had to mod the stove base to fit in the trangia. Now it sits perfect in center at the correct Hight. Test confirms it works well. The top of the burner to the bottom of the pot gap is just between 3/4”-1”. I’m happy with that. I can raise it or lower it up to 1/2” either way so I’ll have to test it out. For anyone looking to use gas canisters in their trangia but don’t want to spend the $60-70 on their gas burner or $190-$200 for the multi-fuel burner this can be a cheap option for just under $20 total. Plus it’s got a Piezo igniter!
    Just thought someone might find this useful.
    Here’s it in the base.
    Forgot to mention that the burner originally had pot supports on it but I removed it to minimize the overall size so it will pack in the set!

    I’m working on a longer adjusting knob that’s simple. I came up with just a simple wire.
