A smoke system with tank can run around 12 oz empty... might get by with 8 using a TME or something like it... Though ths plane would take smoke no problem and still fly nicely, I wouldn't add 12 oz plus 12 oz of smoke... That's 1.5 extra lbs on takeoff...
I added a 16oz smoke tank with sullivan pump and 1600 liion pack to run it... plane still jumps off the deck and climbs out of site with full fuel and oil..... Smoke ROCKS
