Model rockets can withstand huge acceleration forces, so they tend to use high impulse, high force motors with fast burn times. Then coast to apogee. You can model all this stuff in a free program called open rocket. You put in your dimensions and weights and the motor specs and it tells you how high it will go and generates acceleration and speed curves for the flight.
