Flight Log: 7-27-14.

Four flights on the Goblin 500.  Last resulting in a crash landing.  Need to figure out what went wrong.  Lost power during inverted flight about 50 feet in the air.  Was able to turn it right side up and pancake into the ground.  

Two flights with the Goblin 700.  First flight resulted in a power out as well but was able to autorotate safely to the ground.  Oddly, power regained just as I was about to touch down.  Second flight I remained in idle up one and kept the flying easy.  Trying not to create a power surge.
