Hi Kevin,
did the change on the rear engine because of a crack one year ago. Old engine had already 1800h.
We were told better to take CB because of the strengthened case (abt. $1.000,- increase in cost as i remember). So we did.
Took the engine directly from TCM with new cylinders.
Until now everything is dry (after 150h) and hopefully this will stay.

Was really nice to see that the engines can go far beyond tbo without mechanical problems on the moving parts. The cracks are well known already from the cessna 172 rocket (same engine) and the change in the housing is belived to overcome this engineering related lack.

Saw already a post where crack in the heavy case were reported. Was this a CB or C ?

regards
DF3AV
