Buccaneer.. yes, can add more sticks for greater smoke.. can also add an aluminum mesh, inside to absorb and to radiate heat to a great extent, and instead of using a fan and one other ESC, we can use a spare servo, or a servo unsued, or a servo with damaged gears, as taking out its motor and printed circuit board, while removing the potentio meter, and adding two 2.7 kilo ohms resistor, so we can make a simple blower with foam board, and the blower can fitted with the motor of the servo.. so, by connecting the servo to a desired channel, can run, adjust the speed, or can make puffing action by switching on it and off.. with the power from the RX itself.. thank you..
