RE: jato bottles
last fall i took a multiplex funjet, put a ducted fan motor on it, chopped off the wingtips and glued on cardboard tubes to house a estes C6-0 in each wingtip. soon as a flip the switch that baby is gone! i had to use a seperate power system to light off the motors. used a real small reciever pack, hooked to a futaba on/off switch, with the output y'd off to go to each motor. i use a micro servo to activate the switch. the cardboard tube is plugged so when the motors are spent, they jettison themselves with there ejection charge. works great.
