Aircraft frequencies aren't allowed to be used on ground vehicles although I doubt you would ever get caught. Unless you shoot down someones several thousand dollar airplane and they come looking for the cause. It is easy to do if you are both on the same frequency and you send the other into the fail-safe mode. Unless you are using one of the new spread spectrum radios then its almost impossible to affect the other craft.RC controllers have been around for decades, and are very refined, there is no possibility for cross talk in a well engineered RC system... They work very well. There are commercially built RC riderless Commercial Lawn Mowers / Slope Mowers
a robotic mower should be self contained, no need to interface with an operator.. :smile:KennyV
I still would like to see a remote control mower.
