@sickburnbro EHHHHHHHHHHHH
IM AWARE OF THEM
THEY'RE ALL JUST FUCKIN AIR PUMPS
LIKE THE VANE MOTOR
THEY HAD A GOOD REASON TO NOT GET BUILT EVEN WITH MODERN TOLERANCES AND ALMOST EVERY TIME JUST BY LOOKING AT THEM MY FIRST THOUGHT WAS "OH THIS IS GONNA WEAR LIKE SHIT"
MODERN UNOBTAINIUM MATERIALS, TREATMENTS, WHATEVER
OH
THIS THING NEEDS WANKEL EDGE SEALS
AND OH
IT'S GONNA EAT THOSE EDGE SEALS
AND IT'S GONNA EAT THE CRANK PINS ITS GONNA EAT THE NEEDLE BEARING SLEEVES

IT'S ALL STUFF THAT'S COOL FOR AN AIRCRAFT BUT NOT FOR THE CIVILIAN LAND VEHICLE INFREQUENT AND LESS THAN DILLIGENT MAINTENANCE CYCLE
