As for the 65LA having more power, that is not true. The 65LA is rated @ 1.7bhp @16000 RPM. while the 61FX is rated @ 1.9 @ 16000 RPM.
--- Sometimes we get hung up on power ratings. ---
You are making the mistake of believing OS's advertising [:'(]
Go back to torque wrench's post (#12) & read Dave Geirke's dyno-test data. The OS 65 LA does, in fact, out power the 61 FX. It also makes more torque -- at the real-world RPMs that we use.
