This thread does seem to be dead, I have three X2's man I just love them 8+ min's running hard with 8mm venturi with my truggy running 50-15 gearing. I have never had a problem, broke them in properly, I put two litres through them racing before replacing the rods and when I inspected them they had no slop at all but I replaced them anyway, I sometimes feel that all to often people short-cut the break-in procedure with most engines and I know how tight these things are I could imagine how much strain and pressure would be put on a rod in this engine if it were to be run to hard to soon and it doesn't surprise me one little bit that this is a common problem with this engine for that reason, its the Rolls-Royce engine of RC
