I am impressed, AeroMomentum. I know this is supposed to be a thread about a different engine company. I have a thread called Project Bush Demon. I am designing a STOL bush plane. I would like to ask some questions there if you if I could. My thread is totally a design thread, I don't have a pilots license, or funds to build a plane. I am working on sketching designs, and ultimately blue prints for a STOL back country bush plane. I believe I found the power plant I want to base those designs on, and would love your input.I would love to run one of my engines at full power until it fails. A customer (airboat) went 4000 hours. Admittedly, it was not always full power. But also it had very limited maintenance. So 4000 hours at full power with regular oil changes should be possible. Assuming 6gph (on our 100hp at full power) and $3/gal the fuel alone is $72,000.00. We have 8 versions with most being more powerful and thus using more fuel. So about $1,000,000.00. Just for the fuel.
But this is way more than what is required for certified aircraft engines. According to §33.49, engine certification endurance requirements are 150 hours total test run time! Of this 150 hours only 105 hours is at max power. We have done more than this and inspected for wear.
