As I said, I have no idea what a linear actuator is and neither does any of the team.

(to george) alright, mabye 3 is a bit overboard, so I may just put in 2, one for 2 spikes and 1 for the other.
Did more research on a specific linear actuator and found these.

Once again I don't know how good they perform or if they are any good at all. It says each one can lift 76kg and runs from 3-18 volts,the recommended is 12 volts. This could be ideal for us as we would easily be able to lift a featherweight and heavyweight with ease, the only problem would be to balance it all out.

It also states that they are surprisingly light for the power it gives, but I still have no idea on how they work and how to connect them to my interchangeable spikes.

Also, leave a comment on any interchangeable weapon you would like to see in an event. Your support is greatly appreciated.

Many thanks
