Introduction

Also called "RockSim XML format" and using an '.rse" extension, these files are used to describe a motor for loading into Rocksim and OpenRocket.

RockSim v8 uses either the RASP or the new RockSim XML format (.rse). The .rse format can store extra information about the motors, such as the type of engine it is (single-use, reloadable, hybrid).

For more information about entering motor information into Rocksim, please also read the FAQ entry: [1]
