I recently posted about Joe Barnard adding thrust vector control and other advanced features to model rockets.  The goal is to model not just the appearance of large rockets but how they take off and fly as well. This weekend, he successfully flew for the first time a model he built of the SpaceX Falcon Heavy, which involved separation of the two side cores and the in-flight firing start-up of the center core.

The side boosters executed a 20 degree roll program with a rate of 30dps, beginning at T+0.9. Initial pitch-over of the vehicle at launch was due to thrust inconsistencies between booster motors. Because of a low level coordinate transformation error in its flight software, the center core flew with poor stability, correcting roughly 20 degrees off axis for both pitch and yaw. Photos from the flight can be found here: https://bps.space/gallery/
