...In the beginning of the operator's manual, it stated:
"
Danger! This engine, by its design, is subject to sudden stoppage! 
Engine stoppage can result in crash landings. Such crash landings can lead to serious bodily injury or death.
Never fly the aircraft equipped with this engine at locations, airspeeds, altitudes, or other circumstances from which a successful no-power landing cannot be made, after sudden engine stoppage."
The operator's manual also stated: "Warning! This is not a certificated engine. It has not received any safety or durability testing, and conforms to no aircraft standards.
It is for use in experimental, uncertificated aircraft and vehicles only in which an engine failure will not compromise safety. User assumes all risk of use, and acknowledges by his use that he knows this engine is subject to sudden stoppage."
