Since I don't know how to attach a video here I've instead provided a link to the very first
F two stage rocket I tested at Estes. Sorry but this clip only shows the first stage engine and not the ignition of the second stage since my camera shut down. This model is two inches in diameter.

NO these motors don't have a big kick off the pad but they have a long burn, couple that to an upper stage with another three seconds of burn and you have a real high flying rocket. Like I stated before I've flown 24 ounce rockets with NO problem at all with these motors.
