Heaters have landed!! Very fast shipping for a change and before Chinese New years! I have tried them as a direct replacement but the board does not supply enough power to the heater. It was great for a 30 minute heat up and awesome blue vapor...but that is not what i am about! I think the new heaters resisitance is too high for the control board. So i took it all apart again and am using a dimmer control, similar to the E-Nano controller. I can go from blue to combustion using this controller, so i am not set! Unfortunately it looks like a mess... So once again i am thinking of harvesting the guts and making a nice wooden body for it and possibly isolate the heat core with sand, not sure though... I am also considering harvesting the E-Nail digital controller off my Sub and turning the Cloud into a Cloud+++! LOL! As it stands now, it works like a bomb! I can see a very light reddish glow from the heater at higher temps and it can glow red hot as well...Not recommended! Without feedback control the temp climbs a bit so it is full manual control for now. Feels great to be blowing massive, tasty clouds again! Once i have a stable configuration, i will post pics! For now this is NOT a direct replacement! EDIT: I still miss my EVO and regret trading it... This will do for now!
