Bill,
If you find out before I do will you let me know about the = additional=20 depth to be cut.
On the balancing; I have to cover all that with my one rotor ( no = biggie), I can give you all that stuff a little down the track it will = only=20 require lightening the counter balance weights a little.
 
The e-shaft is the same, the rotors lighter =3D lighter balance=20 weights.
There may be some oil volume difference (read weight) , but = I should=20 have that soon, as well the rotor weight. BTW Tracy's apex seals are = 33 grams=20 ( per rotor) - got them to-day.

George,
the apex seals do not go into the balance equation because they = are not=20 attached to the rotor.
