I have a good one...
Any LST guys ever have a losi header crack? I had a header crack on my original Aftershock-converted LST2 in the center straight section of the header. I just recently noticed 2 or 3 cracks in the header on my SH .28 LST2 in the same spot as the last one. The engine tuned fine and runs remarkably better on my homebrew fuel. I have a few spares so its no big deal but I was curious if anyone else has had it happen.
No, I didnt overheat the engine. No, I didnt run it lean. I have been running 20% nitro, 12% castor oil, and 68% methanol.
I'll post a pic of mine when the camera is done charging..
