Rummbolt explores whether the new Wolverine Inferno XTS engine can finally cure the dreaded "midcap syndrome" in MTW airsoft replicas. This annoying issue causes BBs to fly unpredictably as the magazine empties, usually because the high-pressure nozzle pushes the BBs too far into certain types of hop-up buckings. He compares his reliable, mostly stock setup against the new engine to see if the "extended stroke" technology allows for a wider variety of aftermarket parts without the usual headache.

After cracking open both engines to reveal some shiny new metal bits and a monolithic internal design, the testing moves to the field. Despite the fancy name and structural changes, the XTS doesn't quite live up to the hype in the bucking department. While it looks promising at first, the midcap syndrome simply decides to change flavors—swapping the usual under-hop for a sudden case of massive over-hop. It seems the new engine hasn't quite figured out how to play nice with every bucking on the playground just yet.

In the end, the results suggest that if you already have a functional Gen 2 engine, you might want to keep your wallet closed for now. Chronograph tests showed the XTS was actually a bit less consistent than its predecessor, and the accuracy gains were debatable at best. Unless you really need the specific recoil stock features, it appears the best way to keep your MTW happy is to stick with the tried-and-true stock setup and let the XTS stay on the shelf until it passes its awkward teenage phase.
