With Altical it is possible to make an indicative calculation of the height and speed your rocket will fly. Altical assumes an perfect stable regular rocket which is launched vertical. To make an calculation just input the mass and diameter of the rocket and select an motor. When the desired motor in not available you can simply input the motor data yourself.
The risk of using Altical remains entirely with the user.
The NAVRO accepts no liablility for the use of Altical or the NAVRO website. In the Netherlands launching rockets is only permitted for people who are member of an association with the right permits.
