Apogee XT is an analytical tool to predict the flight characteristics of model rockets. Using a sophisticated numerical simulation engine based on Fehskens-Malewicki equations, users are able to calculate the flight characteristics of their simulated model rockets.

Model, save and optimize your own rocket, motor and launch set-ups.

Find your model rocket's expected apogee, maximum velocity and flight dynamics.

Variable air density modelling for improved accuracy.

Dual Stage Motor Input
