When I saw this spider remote control Focalprice thought, I have to buy!
It was only $ 13.00, postagepaid, It's just that you no longer have to sell. Just… found only on Ebay and another lesser-known site.
He has two motors, one that allows a move to shipping and back and another that spins all the spider around its own axis.
The remote control also has two double buttons, a to make the spider go back and forth and another to run the spider clockwise and counter-clockwise. Spider and LR44 battery-operated remote control, similar to those of clock.
I made a video to show you how it works, see all:
I will leave the link of Aliexpress I think reliable, but it's too expensive!
