Trip Barber collected some info on various Foreign motors back in 1978 or thereabouts.
Trip says the curent czech delta motors conatin AP/Butyl Rubber.
If they were made from Bp and stored as they should be, I would make a SWAG that they would age like our BP motors. Back in the 60's the Czech ADAST motors were nicknamed "widowmakers" because of their tendency to explode.... they contained all sort of exotic ingredients: AP, nitrocellulose, picric acid,etc etc
I personally don't know if modern APCP have any temperature or humidity related cycling problems like BP does.
