No, but a poster has shown that the maximum take-of weight of WL-II is 4,200 kg. A UAV with 4.2 T maximum take-off weight has a playload of 480 kg? Then that should be designed by some amateurs, not expert from 611. You can find this inconsistency from ratio of playload to maximum take-off weight by comparing several UAVs, such as reaper - 0.26~0.36, CH-4 - 0.3Are there any sources that indicate the WL-II's max payload (non-export variant)?
Moreover, how could a UAV with 480 kg playload takes 250 kg bomb when a minimum of a number larger than 500 is needed?
