Nice to see this tread alive and kicking with Propello doing Q&A!

I've updated my RDA using a steel rod instead of the original cap. The rod is 7 cm long and has a 22 mm outer diameter. It slides inside the bottom cylinder. I used the o-ring which came with the vandyvape kit to close of the air. I created two air gaps. Turning the rod adjusts the opening amount just as with the original cap. I used a short PVC pipe as mouth piece. The air is closed with some layers of teflon tape.

This setup enables longer mesh lengths. Mine is 7 cm long (fully stretched out). When inserted it sticks out around 2.7 cm. This wouldn't fit in the original cap. I will be loading spice horizontally as Aum originally mentioned. Much larger surface area and no drip. Can't wait to try.  

Curious about the e-mesh buckets which sbc1 mentions. Have you tested it and would we be able to buy this?

My current setup:

Joytech eVic VTwo Mini 75W

VandyVape Mesh RDA

VandyVape SS316L 150 mesh 70x13mm

Steel rod 22mm diameter, 7cm long

(150 mesh works, but I think a 100 mesh would be optimal)

The only downside of the tek is that sometimes the temp isn't being calculated correctly. Could it be the Joytech TC algorithm? I read more people having this issue here. Also its unfortunate that there is such a big difference between mods and settings.
