First time using a PML piston ejection system tomorrow. It's not too warm over here in the UK so I know the QT body of the rocket could shrink a little outside, but how loose/tight should the piston be.
At the moment, it doesn't fall out, it takes a gentle pull of the shock cord to drag the piston out. Should it be sanded down to be a looser fit? Should there in fact be a small gap around the diameter to let air past?
