I have to ask... How many AA's does your toy take. That thing has gotta take a lot if it's spinning 10,600 rpm's. No really who's heads are on that thing that will support that many rpm.

When you detonate the piss out of the motor the piston will want to rotate in the bore. The I-beam design is alot stronger as far as twisting goes. I think I still have some pics in my old phone of a set of rods that came out of a nitrous motor with a bad tune up. This is not a big mystery to nitrous builders.

Just my 2 cents butt most of the time when a Rod fails.... something else has happened first (spun bearing) oiling issue "something" its not to often they just break , not saying they can't or won't break but rarely.... I was IHRA Record Holder in 84 and 85 in A-Gas 468 bbc with tin-dipped chevy rods 8600 rpms never a problem. I know thats different from boat engines but as others have said.... tune up.. Clearences when built etc etc will blow one up quickly.
