The attached files are replacement parts for mission 80, the launch of the Infrared Space Observatory (ISO) for the ESA. For this mission the Ariane 4 was configured as a 44P H10-3 using 4 solid rocket motors and the H10 3m fairing for the spacecraft. To build this model you will need Niels Jahn Knudsen's Ariane 4 (44LP) paper model available at www.nielspapermodels.com. My recolor replaces parts 8C and 10L from his kit and is presented in both the 1:96 and 1:144 scales.
