Hi guys,
After experimenting with plastic (3d printed, glass transition around 60
celsius) model rockets, I found that it is pretty feasible. However between the
motor casing and the plastic body tube there is a pretty good insulator needed.
For 38mm and 54mm motors it is enough to use a cardboard tube, but anything
higher, I am not comfortable enough with cardboard. Do you guys have some
recommendations for ‘easy’ to find materials?
