Just had my 2 nemesis clones arrive - posted 7th nov, arrived today, in case anyone is wondering about shipping times.
Just had the same issue figuring out how to build the nemesis for 18650 non kick mode..basically you need to remove to kick ring at the 'head'/atty end, then use the 2 bigger tubes and the switch end for 18650 mode
atty end has airflow control ring, then the head itself, then kick ring - i removed airflow control to get a good grip then unscrewed the kick ring.
Protip: screw your atty into the top ring, then tighten the adjustable centre-pin onto it before screwing the top ring onto the main tubes and finally the bottom cap. You'll get a perfectly flush atty every time and you won't ever screw the centre pin down with the atty and lose the connection.
Also, how diddy is it in 18350 mode! Doesn't last long at all though.
