Analysis

During the takeoff roll, it appeared to the plt that the eng was not developing full power. The ultralight was not equipped with a tachometer & the suspected loss of power was based on the plt's estimated lift-off point. The plt further stated that he was wearing a helmet & the eng noise was muffled making it difficult to determine eng power. The takeoff run was longer than normal. He continued to climb out & with what appeared to be a partial loss of power attempted to set up a glide. The ultralight stalled while the plt was avoiding trees. Two witnesses stated that the eng quit.
