Well, I probably raced by XX for about 5 years week-in, week-out, back in the day & I never broke the front bulkhead... in fact the only part that I can remeber breaking was the rear 'T' shaped pivot plate on the original XX configuration, they were strong buggies! I can only think that either the part has become brittle with age, had already been weakened by a previous shunt or was under 'stress' due to having screws either over tightened into it or the 'teeth' where the pivot pin goes through for the 'X' plate were not de-burred properly???
Where did it break? - I can remember perhaps one or two of the bulkheads on my friend's Losi XXs but I think each time it was where the teethed part interlocks with the top brace as described above.
