Normal landings and flat drops are fine. The one case to respect is a tumble that lands on a motor from about a metre onto concrete. Grass or dirt cuts that load substantially, and if your testing shows motor-pad damage the fix is a small TPU bumper under the pad, not more frame. Drop numbers assume hard ground, no cushion, and ignore the TPU belly pan and the extra impact strength printed nylon shows at speed.
