Smaller however, than the General Electric GE90 on the Boeing 777, they're between the size of a GE90 and a GEnx, they put aout around 85,000lbf. For some reason, only inboard engines have reverse thrust.

It's only inboard because of weight*, however some addons have all 4 engines with reversers.
But then those addons were mostly released before the aircraft was rolled out, so they didn't know that much about it then.
