Jamming RC control is not that straightforward, and for good reasons: it's common for several pilots to operate RC-controlled vehicles from single airfield simultaneously, thus RC radios evolved to avoid interference with one another. While modern RC radios indeed usually operate on 2.4GHz band common with WiFi, they typically employ frequency-hopping spread-spectrum communications[1] that has nothing to do with WiFi and is designed with degree of robustness against interference. Secondly, many `drones' (in this context, quad-rotors and multi-rotors) are catable of semi-autonomous operations, such as position holding, following a pre-planned flight path, and automatic return-to-base, as both aide to pilot and a natural protection against losing radio contact with the remote control. To combat those capabilities you would have to jam GPS signal too, and most probably the end result would be drone simply drifting with wind and slowly changing altitude, instead of dropping out of the sky right away. Not to mention jamming nearby neighbours and motorists, and illegality of such jamming [2].
