Go on about remote-controlled aircraft (5)
I believe the answer is:
drone
This clue might be a double definition.
'go' is the first definition.
(droning is a kind of going)
'about remote-controlled aircraft' is the second definition.
'drone' can be an answer for 'aircraft' (drone is a kind of aircraft). I am not sure about the 'about remote-controlled' bit.
'on' acts as a link.
Can you help me to learn more?
(Other definitions for drone that I've seen before include "Member of Wooster's club" , "Male honey bee, an idler" , "he gives us a buzz" , "Speak long and tediously" , "Monotone" .)
