heavyweight ram bots?

[dgr]

Yeah, Wilhelm's Scream was a rambot and made the second round of the UK champs. None of the heavies I've built have been with active weapons and they've all won fights. It did run on NPC motors rather than wheelchair ones, though we have successfully used wheelchair motors in other heavyweight rammers (most notably the first Cabrakan), and I have a couple lying around that I plan to use in a second heavyweight soon.
Very much a place for them, as long as you're in the weight limit, any new heavy of any ability is always welcome.

who did you end up winning against?

also, and pics of videos of it?

[dgr]

Well, it was less a case of winning, more a case of survival of the fittest sometimes
I managed to drive Cabrakan one to a flukey and pretty unsporting victory against Apocalypse, which I never let Ed forget. That fight is here:

Anger (sort of) held its own for a good long while against Scorpion and Big Nipper in this fight:

Then Wilhelm's Scream managed to hold out for a second place against Meggamouse, Mantis and White Knight at the O2:

And was one of only two robots still moving at the end of a fun battle with Tilly Evo, Tiberious, Bullfrog, Disc-Truction and Wilhelm's Scream, once I'd fixed my wheel issue, but I can't find a video of that one.

There are plenty of robots without active weapons that still perform brilliantly. Saint springs immediately to mind. It has an active weapon of sorts, but doesn't use anything other than the two drive motors to power it.

Wilhelm's Scream is certainly one of the more unusual heavyweight ram bots out there

[dgr]

It shows what someone with very little engineering skills can accomplish. Think I'll build a new one now though.

any internal shots of it?

[mattsdragons]

any good uk or american ram bots that were sucessful? (appart from tornado and storm 2)

[typhoon_driver]

nope, you have the good uk ones there, no idea about american bots

To build a decent rammer you have to use decent motors, used a couple of eteks in my last one that were underpowered because the travel on the spektrum tx limited the speedos. Even with this limitation and being on 24v instead of 36v the bot still pushed others around very easily

[mattsdragons]

So the key is either powerful motors or Bosch 750's with a good reduction?

[jonny]

the key is powerful motors. you're not going to have a very good rambot if it moves at 5mph. storm 2 uses lem 130s i believe and runs at 25mph so if i were you i'd aim for 20+ mph and use eteks. lem 130s are hard to find now and cost over £1000 pounds each where as eteks are much cheaper. the new etek r (replacement of the original etek) costs $470 from robot market place. i have also found a very high power motor that looks suspiciously like an old style etek popping up on ebay alot:
