Relay and speed controller

[Max]

I know this is the wrong forum for this but never mind-
What do most people use as a relay for the weapon motor on their ant weights?
Also are there any cheap speed controllers you can use for antweights so I don't have to use servos?

No one uses relays on their Antweights. Most people use brushless motors and esc.

What size brushless motors do people use for drum spinners?

[harry hills]

i use a 15g one

If you are wanting a spinner, antweights tend to use brushless motors between 18 and 22mm can size. You need a special brushless control for these motors.

If you are using a gearmotor for, say, an axe or motor-powered flipper, you would use a small single channel ESC such as a Banebot 3A or a Scorpion Mini, both available from Robot Market Place.

I've built a couple of antweight drum spinners- both of them use an 18mm diameter brushless motor which sits inside the drum. This was controlled using a 6A brushless ESC
