INSUBCONTINENT EXCLUSIVE:
The Prowess microdrone, weighing less than 250 grams (8.8 ounces), reached 340.78km/h (211.75mph), setting a world record for
remote-controlled microdrone quadcopters.The record was broken by model aircraft enthusiast Xu Yang on March 23 in Huizhou, Guangdong
province, according to a WeChat post by Guinness World Records on Monday.According to Chinese media reports, Xu is a student at the Chinese
achievement broke through a limit in the field that had not been surpassed in three years, marking a milestone in the design of
micro-unmanned aerial vehicles.Xu was inspired to build his drone after Quadmovr, a content creator that designs and builds
remote-controlled aircraft, proposed a microdrone concept in 2022 and built a prototype that reached 219km/h.This unofficial record was
broken by Xu in October after his prototype reached 244km/h during a test flight
After consulting drone builders overseas, Xu improved the design and speed of his drone.For the microdrone record, the drone had to weigh no
The Prowess drone, weighing around 247 grams, features a lightweight carbon fibre frame, an ultrathin 3D-printed shell 0.4mm thick and
3D-printed high-speed propellers that were designed by Xu.Xu found no finished propeller products on the market to fit this need, so he
undertook several rounds of design optimisation to develop his own, according to the post.Before his record attempt, Xu heated the drone
battery to about 40 degrees Celsius (104 degrees Fahrenheit) to ensure it was at peak performance during the test.Swiss engineer Samuele
calculation method used to analyse flight data, which had been given to Gobbi by the previous quadcopter record holder.Xu said that between
drone speed challengers, there was no competition but rather cooperation, and that he would be willing to share his experiences with future
because of motor overload
