What say you about using the heavy manual= transmission flywheel if I can get it milled and fitting?

Hi; Dave,
 
I=E2=80=99m very thankful to hear that this occurred after landing.
 
I=E2=80=99ve been unable to post on the rot= ary engine list for months due to blocking by Cox.  Perhaps you=E2=80= =99d post this message on my behalf:
 
---The shear pin on the sun gear is the mo= st likely candidate since it was sized for a normally aspirated 13B.  = After the failure on Marks 20B, I have changed the pin diameter
 
Tracy;
 
Doesn=E2=80=99t t= his suggest that all 20B and 13B turbo should be upgraded to the larger pin= ? When was the failure on Mark=E2=80=99s 20B?
