The MBRTV58 is the 58mm version of my high speed test vehicle. This is a custom made 58mm rockets to use for speed and atitude records for research motors. 58mm you say, yes 58mm. With the issues of finding 54mm tubing for motor cases and now wanting to pay for it or turning down two inch schdule 80 pipe to make 54mm motors, I am going to standardize on 58mm .125 wall tube. This will allow slight higher pressures and a little extra propellant. The big plus is that I don't have to machine the case except for the snap ring grooves.
