Shortly after launching the throttle cable developed lost motion resulting in power loss. I was over the mining pit at 300 feet at the time. Turned back to the LZ and landed without incident. Linkage broke and will be easy to repair with some safety wire.
There was a low ground fog that dropped the surface temp 10 degrees to 65*. Nil wind. Set up at the edge of the field and launched without drama. One the hour flight. Loitered over the mining operation and climbed to 2700 feet. Few birds and very little activity.
