Panther jet

I purchased two panther jets. Both flew the first time, but after that neither one would develop the power needed to take off. Any suggestions or advice!

PJM…Please provide specifics….
battery type/brand
runway surface type (grass?)
temperature (density altitude) for success vs fail flights
anything that might have changed?
battery charge condition?
ESC calibrated?
