Hope that these could help. Skywriter smoke pump, 3S Lipo, 32 oz DUbro tank and 1 Tam tube for spraying super dry smoke oil.
I chose to build my smoke unit fully independant, i.e with only 4 screws i can remove the whole unit. I am still experimenting with already good results and might add a second sprayer to possibly increase smoke denssity during flight.

Regards.
