Looks like they are pretty new and have one flying test bed. Their site has photos of many other aircraft, none of which appear to be powered by their engines. No mention of testing regime, ground run hours, flight hours, how many examples flying etc. This would be important in my view before investing in a new engine design.
I'll put this out there to others developing engines for the aero market. You need this info on your website. I've asked 2 others here and on HBA to comment on the testing program and hours on their new engines and they've completely ignored the questions. To me, this means they don't have much testing done which means to me, you shouldn't even be thinking of releasing their new engines to paying customers. It also reflects badly on their credibility.
Listing any TBO figure without at least one engine getting that many hours on it without problems is just a guess. Only actual running under similar to flight conditions (with prop in place) will validate.
FEA is also no substitute for actual hard running as we've seen on some "big block" Lycoming clones with serious crankshaft problems.
It's easy to make lofty claims, much harder to back them up without real world results.
There should be no rush to get to market without a solid, comprehensive, test program behind any new engine design. Usually this incomplete testing just bites both the manufacturer and initial customers.
