If you want to 'take out' any 2.4GHz RC system, it can be done easily, inexpensively, and also legally. What you need is four 250mW (or greater) 2.4GHz video transmitters. These transmitters are analog in nature. There are 4 different "channels", each occupying exactly 1/4 of the 2.4GHz bandwidth. if you turn on all 4 at the same time, each on a different channel, then no RC control system (be it XPS, Spektrum, Futaba, Hitec, FrSky, HoTT, Airtronics, JR DMSS, etc. etc) will even connect with a receiver. Effectively, the entire 2.4GHz band will be wiped out. This is why modeling clubs should NEVER allow 2.4GHz video transmitters at their field. 433MHz, 900MHz, 1.2GHz, and 5.8GHz are all fine.
