SR...it's not the rod...it's the crank pin that MIGHT be "iffy"...
You can be the "Beta tester" for us, aye!
We will find out as more and more people start flying the .60NX, if they have the bugs out of their crankshaft metalurgy.
When Horizon starts selling their Phoenix 7 ARF and the .60NX that they recommend for it...there will be a bunch more of 'em out there.

The Evo .52's and early Magnum .52's (virtually identical internally ) had over-hardened crank pins...I recall reading of several of them breaking.

My early Magnum .52 had seen well over 15K when I had it in my Kaos .40
I fly it now with a 12.25x3.75 APC however, on 15% and the revs are down to a little under 14K. (it's still running great )
