Lehner 3080 / 8 Brushless Motor ? fault

Hmm ... as long as motor kv x Volts does not exceed max allowed RPM there should be no issue revving a motor without load (aside from a fast rise in temperature as there is no airflow aroung the motor). The 30 series Lehner motors are specified up to 50000rpm. 50000rpm / 39V = 1282kv. Even the hottest 3080 motor (3080/5) is below that mark with 1050kv which might tranlate to a max of 1150kv with no load. Still safe @ 39V ... but i suppose you chose a kv well below the 1050kv mark.
