It's sort of dawning on me how on the ball I am gonna have to be building a heavy weight. I was ready put my cash into building a serious featherweight but really fancy a shot at a heavyweight instead lol.

[daveimi]

well...actually the plan originally was build a featherweight from plastic and roberts your mothers brother. But after a crate of hdpe etc and various builds I wasn't happy with the way it flexed. So then I've been building a daft robot out of a roasting dish and bits of angle / steel plate and i've ended up having to buy metal cutting and drilling gear anyway. So now since I've gotten this far, I keep watching the heavy weight stuff on youtube and thinking I want a go at that. Would your advice be build another feather or two first and then have a go or would you advise getting stuck in?

Have you competed with any of your featherweight efforts? If not, it might be wise to do so, get your sea legs as it were, and decide from there. You may be completely satisfied with the more intense and lighter machines.

[daveimi]

Good point lol, no I haven't. Yeah, I'll finish the roasting dish off and come to some events and take it from there lol. Sorry for the stupid questions.

I think you should go for a really competitive feather. They are much cheaper, parts easier to find and they are easier to build. And for what i see here in the forum, feathers seem to have more competitors. You could also build a beetle, since many people are building them and as it is a new class, there is still much for everyone to learn and create.

[daveimi]

Yeah, gonna have a go at building something to give featherweight spinners a hard time, as there what I'm most scared of.

[Merkabah_PT]

Breaker Box, the so called spinner killer, super simple design but effective. Built by Jim Smentowski who was all about really big vertical spinners (Backlash/Nightmare), so he must know what it take to take care of one.

One of the secrets is to drive well, trying to only get hit on the biig Ti scoop and get on the side of spinners. So, practice alot your driving.

Hope this helps, i would love to see some one build a robot that scares spinners.

Sadly I think the best bot to defend against spinners is the standard wedge. In fact a really shallow pyramid shape bot, that simply deflects every hit from all angles, would probably survive the longest. Possibly even a low dome shape. Of course, that's boring.

Something that has a long shallow wedge leading to a grabber of some sort, so that you can deflect hits and when the time comes grab your opponent and get rid of them, would possibly give the best results. You don't need particularly fancy stuff to get enough power to grab a machine.

Then again all designs have pros and cons, that's why there is so much diversity.
