I always keep a couple of spare smok dual coil carts handy. Works well in the airplane and I dont get flooding issues due to altitude changes. The only way i can keep tanks from flooding during flight is to store it upside down and loosen the bottom cap. (fwiw, I'm flying a non pressurized twin) So climbing up to 10k, my protanks become pretty useless if I dont upen them up during the climb. Once I'm level, I can close them up and Vape on!!!! Nice to know I'm not crapping up my vacuum instruments with yellow nicotine crap from an analog. Plane smells much better too! Why smoke and drive, when you can vape and Fly? lol
