Multifunction arduino robot - beginer

[Radu_Andrei]

The budget is amendable. It would be nice to stick to it, but if I'll not, that's life.
The Turnigy 9x, 8 channels goes here for 60-70 pounds plus another 10-15 for the receiver. It does not say if the batteries need to be purchased separately, but I guess so.
I found only a second hand FrSky. (I am not a fan of second hand electronics)

On amazon.co.uk there are a lot of models, up to 16 channels, around 50 pounds, for sure of inferior quality than what you have mentioned, and I also checked drones and damn, they got a lot cheaper since I last checked. But never mind, around 100 quit for a durable remote sounds good to me.

I'll wait a few days, to see if someone else has other model recommendations.
So I got an RC transmitter, batteries and a receiver. 4 servos (2 in the head, 2 in the tilt/pan neck system), and I guess some batteries on board.
What else do I need?
