Even as the initial 400 gliders were being produced, several problems with the Hotspur's design were uncovered, the primary one being that the glider did not carry sufficient troops. Although it had been designed to transport eight airborne troops and a cargo of , this was found to be inadequate. Tactically it was believed that airborne troops should be landed in groups far larger than eight, and the number of aircraft therefore required to tow the gliders needed to land larger groups would be unfeasible; there were also concerns that the gliders would have to be towed in tandem if used operationally, which would be extremely difficult during nighttime and through cloud formations. Its disappointing glide ratio was also a contributing factor to reevaluate the assault glider concept.
