daaamn that was spendy, but ya dont feel ripped off for a one off
big smd tax, shits 5v too which is drama
ham: you can do that with linear motors
thats basically what im doing now
like, we do some pids and get some plots, and use shit like overshoot and rise time and oscillation period to make 2nd order models
then from that you can work out the spring/mass/damping of the system
ham: theyre probably shielded neo
my guess its neo in steel cups or something
shrug

ya!
tho i want to pretend like they are mini rockets
CFD is expensive so its use limited by the reg
its kind of sad they limit research because big teams keep vetoing budget caps
anyway, they do a lot of testing to corellate models to actual conditions
wind tunnel testing is the same, limited by regulations, so theres motivation to research aero on track test days
track test days are also limited (because michael schumacher lived at furiano) so they dont fuck around
