Update on my ASP Aerobee 100 JR build that I’ve flown this model on G78s and G79s several times now. Great flights all. Notably, our last two section launches had no wind and the altitudes hit were spot on the estimates from the instructions: 3200ft on G78, 3040 on G79. At a prior launch in serious wind it did 2500ft on a G78. So I think just basic, everyday wind explains the discrepancies I’d been seeing from ASP’s projections.
This launch video is neat in that you can see the pressure build up and release.
