Lots of good info in this thread. Thank you all. I got my Kayfun from FT on Monday. It sat in it's box looking at me until I had the time and focus to coil it up yesterday. It was my first coil build but was effortless and works perfectly. I've had some issues today with low vapor and thought I hadn't used enough wicking but after reading this thread I turned up the W and it is much much better. And mountains! Why had I not considered the mountains? I can sit home and vape all day but the minute I leave the house I have problems. I've finally learned to bring extra tanks and coils with me when I leave the house. I thought it was just dumb luck but it isn't my luck that's dumb. I live on the side of a mountain and regularly drive from 500' to 4000' altitude. Sigh. One of those ah-ha moments of feeling like an idiot.
Your puppy is adorable. Make sure you let the vet know her tummy has been upset when you drop her off. I can't imagine it would make a difference but the vet should be informed. Thank you for being a responsible owner and having her surgery done. I work at a shelter and see the horrors of foolish people that don't spay and neuter their pets.
BTW, I love my new Kayfun clone so much I went ahead and ordered a Russian this morning. Can't wait (and wait and wait) to compare.
I think it'd be cool if they put a little screw or something in the top of these things that can be opened to let air pressure in and out of the tank during a 'steep climb'. I suppose you could have such a thing added if you know a machinist.
Yep, a good VV/VW rig, and things with 'adjustable air flow' helps a bunch, as boiling/vaporizing temperatures can change (sometimes abruptly) at high altitudes.
Under these conditions with a tank experiment with the following:
If you can loosen the top enough to break the seal during the climb somehow, and still avoid spills...that'll help prevent pressure induced liquid floods.
If it does flood...tip it upside down and let that little bit of excess liquid in the atty chamber drain through the mouthpiece back into a second bottle (you can vape this later...no point in wasting it)...tip it again, loosen the top enough to let the pressure even out, then tighten it up again.
Air can get thinner as one climbs...requiring heat adjustments, and/or adjusting the air flow screw.
