Thanks for the help. I will swap out the engine tonight (I carry an extra just for cases like this) and see what happens after break in period. If the engine is blown, I PM the Exceed rep and see what assistance they can provide since the engine has less than one gallon of nitro through it.
BTW, congrats on the 10,000 post mark.
I had the same problem with my VX16 engine. Had almost 1 gallon of fuel put in it before it locked up. And yes, it was broken in correctly and not run too lean. Just shipped it back to NitroRCX yesterday for replacement.
