What size tank for an LA-25? I need to make one for it.
I would recommend 3-3.25 ounces. It uses substantially more fuel than a 20FP, and I use a Sullivan SS-4 fuel tank (about 3.5-3.6 ounces capacity) and its full up to about 1/2" from the top.
Obviously it's a lot easier to take fuel out of a tank that it too big than it is to try to put more in one that is too small. Or rather, you would think it was obvious. You would be surprised.
