Quote from: RedRummy;546101the triangular rotor isn\'t rotating in a circular motion, it wobbles back and forth inside the housing... there must be large forces generated by it... I reckon there is a vibration limit in it.

It\'s also \'wobbling\' at about 2.5 (I think) times slower than the main shaft - so at least it\'s not wobbling at the full engine revs.

I found that bearing/lubrication issues were the biggest killer, I kept incresing revs and got to a certain revs were the engine went in a big way, no det, just E shaft flex, and the resulting beakages.
