So. I take my NX7 out to the flying field last Saturday, to break in a fresh engine. Fuel it up, get the electronics fired up, and attempt to start the engine....YS 96SRX.
It hydrolocks, and I hear a snapping sound...then no compression. Today, I decided to tear it apart, and survey the damage I did to my engine.
I get the engine out of the helicopter, and pretty much dread pulling the head off. Fearing I`m what going to see when I open it up.
As I`m getting ready to pull the head, I decide to turn the engine over by hand, and what do I see through the exhaust port? The piston is not moving at all.
Guess what knucklehead forgot to locktite the crankshaft nut!! Hahaha.....the hydrolock was enough to allow the starter to break the nut loose, and let the fan/clutch hub to spin on the crankshaft. Ooooopsie...LOL.
Ah well...it happens to all of us at times. I`m just happy that was all that went wrong. It`s back together now, AND with locktite this time...and ready for another trip to the field.
Tony....I KNOW you`re gonna have fun with me about this one... baaaahahahahahahaha.
