Big Daddy

A few rungs up the ladder toward high power is Estes’ Big Daddy, a chunky, 3″- diameter model. While designed for D and E solid rocket motors, it can easily handle AeroTech’s 24mm F motors. It’s not much more difficult to build than the Astra, but bear in mind that an E motor has up to 16 times the power of the Astra’s A.
