Guys, you're talking about a "national team".

What is the motivation for the bigger robots? I assume a better spectacle for the audience.

50 kg would be easier to transport than 100 kg.

Is a 100 - 200 A ESC on the cards for BotBitz?

This is one other reason I wanted to see MW/HW's stick to simple motors like scooter or wheel chair motors where they have low amperage draw and most people could recycle some of their FW hardware.

BotBitz sorta has a potential 8S 200A controller on the cards, but it requires Steve to do a lot of work and he's currently a bit busy for that Razz

The FRA doesn't have that many 50 kg robots compared to the 100 kg. Is the US the same?

If I know 2 middleweights over here, I would be surprised.

I'm not really following the US competition, to many 1 hit wonders to get my fancy.

Why not allow people to make whatever floats their boat? If you make a heavy, be prepared to fight two middles as a clusterbot. If you make a middle, be prepared to take some big hits. Also, allow middles to fight each other one-on-one, as can heavies.

@ Philip: That recent USATL event had 17 MW bots registered VS only 7 HW bots. Looking back thru recent events on the BuildersDB site, most of them are only going up to 15 lbs, even 30 lbs events are getting rare in the US.

Steve, have you thought any more about a high current ESC?

This was what I had in mind.

http://www.hobbyking.com/hobbyking/store/__24754__Turnigy_Trackstar_1_5th_Scale_Sensorless_200amp_8s_Opto_Car_ESC.html

Just haven't got around to it or really had a reason.

If you did convert the above controller, would it run winch motors?

That was the idea but without testing can't really say.

I was surprised of the speed it got. I always remember from Robot Wars the robots with wheelchair motors were slow. But that had decent speed with featherweight batteries and TZ-85's.

It might be a little slower once you dump 100kg on it and the motors and batteries are both working harder.
