Those rotaries were low tech cool... castor oil flying everywhere...
no throttle, only a kill switch...
They would turn 'with' the motor fiercely, the other way not so much.
Real men flew those things.
I raced a couple Sachs Wankel powered Arctic Cats back in the day. Had a
few 303s and had a couple 606s as well. If you could get the apex seals
to hold up and could keep the plugs clean they ran pretty good. But man
did they STINK....
The worst thing one could do would be to blip the throttle right before
shutting the engine off. That would cause a backfire of dramatic
proportions. In my case, once was enough to ensure that it didn't happen
Light backfiring was perfectly normal when the engine was decelerated. I
de-linked the servo on the carb which kept the trottle open during rapid
deceleration so I tended to get that a lot. A little backfiring when
downshifting is a happy sound to my ears.
Explaining that a little backfiring is normal to a guy not familiar with
the rotary was met with a skeptical look. That's the breaks.
