Hey guys, just before I go ahead, am I right in thinking I can measure the thrust produced by a solid motor with this sort of setup with it facing down the way onto a scale? Figured I could record the weight at different times and convert to newtons etc.1yr ⋅ GreenDhuosnos_ ⋅ r/rocketry

My first scratch built rocket, I had some help building it, but it’s close to the maximum lift-off weight of my intended motor (D12-5). Should I make the switch to F Class Motor?
