A lot of friends of mine raced this last months with these two engines...... and we all have THE SAME "IMPRESSION".........
It lasts much less than the classic type of piston..............
Maybe Novarossi has something to correct in the microcasting process.... but this is the reality.
Novarossi .12 microcasted wear more quickly than the classic type NS12S3!!!
Putting aside the durability issue, did you noticed any performance difference between the two types???? Or they perform similarly.
