Standing over 36 inches tall, the Pro Series II Super Big Bertha comes with the quick-release motor retention system just as the other Pro Series kits do. Construction of this kit is not difficult and the altitudes you will reach are very impressive. Building and finish work can easily be accomplished over a few days. This is an update of the kit originally introduced in 1990.
