QuickDraw #557
Good budget controller but probably not for combat robotics
Fly sky makes reliable controllers at an affordable price and the FS-i4 is no less reliable than its bigger brothers like the FS-i6x. However, do note that this controller is NOT programmable like the FS-i6x. This means that there is no way to program a fail safe. I had originally purchased this controller/receiver for a custom 1lb combat wedge bot for a friend to drive when I go to battlebot tournaments. I was considering adding a little out runner so it would have a weapon as well but this particular controller does not have a fail safe: meaning that it will continue in the same coordinates when the controller is shutdown. Anyhow looks like this wedge bot will not have an active weapon lol.
