The last LS I heard it was a RV10 up in Conroe Texas. It kept overheating. . Finally on the last flight the ECU kicked into limp mode and it’s really limited timing, fuel, and power, they barely made it back to the airport. Nobody knew that was programmed into there, but then again we don’t know what all of the tables in that ECU do. The LS1 came off and a Lycoming 540 was bolted on.

Yes, its true, N730WL was damaged Thursday afternoon during a test flight and subsequent emergency landing. Pilot, Bud Warren and I were taking the 10 for a flight around the airport to check out a high operating temperature problem. We took off after a long taxi and climbed normally, however the engine temperature kept climbing even after leveling off. For unknown reasons the engine seemed to quit making power. Bud skillfully banked back toward the runways. Not a good situation. A discussion with Bud today leads me to believe that the high engine temperature may have exceeded an operating parameter in the ECM and the engine reverted to a low power setting. This has yet to be confirmed but obviously needs to be addressed if this is indeed the problem.
Bud managed to get the airplane back to the airport sacrificing altitude and speed without stalling. Incredible job by Bud to get us back to the runway. However, once over the runway, we were too slow and the plane mushed onto the runway rather hard. We bounced and skidded to a stop on the collapsed main gear. Fortunately, there was no fire and Bud and I were able to get out of the 10 without any injuries, Thank God.
Unfortunately, there was considerable damage to the main landing gear and the prop was destroyed. The steps kept the bottom of the fuselage off the runway while we skidded, so no noticeable damage to the fuselage skin or tail. The wings didn't hit the ground but there is some minor damage from the gear folding up. I haven't looked at the landing gear mounts yet or the spar. So I don't know at this ten seconds the full extent of the damage.
