Hi!

I,ve just bought a commercial drone (a cheap one) and i want to add a servo for a function. How can this be done (preferably cheap)?

Hi I don't think you will that easy, the quad needs a spare channel which cheap toy ones won't have a spare channel
So the only way now it a second transmitter and receiver . There will no were to fit extra parts on a toy quad build your own may be the way to go
