Lehner 3080 / 8 Brushless Motor ? fault

[transtalon]

I had a similar problem with my old setup for my 5" extended Lst2. I wanted to make the Lst2 to go fast on the topend I geared it to high and the same
thing happen but with a lot cheaper components, KB45, Hydra 240 and watercooling setup. I put a +6 pinion on it with a 6S 8k lipo. I think you need to gear it down on your setup. How much does the FG weigh with everything on it? I learned that quick reaction saves other components from going.
