Here's some snippets from the Robot Wars announcement at the FRA forums:

There has been a lot of chat about bringing HW spinners back on our Facebook group,

...I am working on potentially bringing something back which we've been missing here. I'm putting together research and need some substance to my plans.

2016 number of events - 2

Time scale - First event early 2016, second summer 2016 if successful.

HW and FW full combat.

Entry fee to be directly put towards a prize fund for both classes, required on entry.

Agree to sign our RW contract for allowing us to film etc

Double elimination competition leading to a winner.

No house robot intervention during fights

New arena hazards

If you want to join the fun and support it please email me with your likely planned robot entry and a few details about what it would consist of. This is a separate venture to our normal UK tour.

[I've removed the e-mail from this post. It can be found in the original post on the FRA forums, which I've linked to below]

...this is early stages, things are moving, but I need some substance to the plans being put forward.

This is one of two options being discussed at the moment.

Here is the original FRA post for those interested.
