Mammonth

Model #9708

Description

This kit can be assembled quickly with a minimum of effort. The factory applied gold finish is very attractive. On the rocket range it’s lift-off and flight is exceptionally straight and steady. It performs best with an Estes F size 29mm black powder motor and also does well with an Aerotech 24mm F44 composite motor. It’s a great rocket for anyone wanting to get into mid-power with a minimum of trouble and expense.
