Has anyone else experienced a crankshaft failure in the X12T? I have used mine for the past five months in an HPI Super Nitro running 30% clean fuel. Today 4/13/02 during a practice lap the motor quit. The motor had a temp. of 209deg and was blowing good smoke. Upon inspection, the face of the crankshaft (where the rod connects and the counter weight is) was broken into two pieces. Any ideas?

I have seen a similar thing like this once, however the engine was already quite old. How much fuel did you burn with the engine, can be that the use of high nitro% stresses more the shaft so this can happen.
