I am pretty sure Darth has been in on nearly all of the engine and rod discussions. Here are a few of the recent ones in case anyone is interested:

I have also gone through two con rods, though both in a Big Mig 0.61 and not the Vmax6. With the first con rod it broke during the break in period, perhaps after 30 minutes of running. The second con rod broke after the break in, perhaps after 3 flights. I have no suggestion as to how to avoid this in the future. My rod failures have (in the second case, and early in the first) occurred after very careful and very lengthy break in periods following Norvel's specific instructions. Also fuel, nitro, and all rpm were kept carefully at Norvel’s recommendations.

For what it is worth,
