If you friction fit a low power rocket motor, do you need a thrust ring?
Although I have never tried it, I suspect that you can get away with just friction fitting the motor into a tube that lacks a thrust ring if you are using 13mm 1/2A or 1/4A motors. Just make sure that the fit is firm. I think that in those situations, the greater risk is that the motor will kick when the ejection charge fires. I wouldn't recommend doing this with Micromaxx motors, though, because they have pretty hefty thrust spikes for their size. The same is definitely true of 13mm A10 motors.If you friction fit a low power rocket motor, do you need a thrust ring?
