Hi Luke

Assuming you're referring to http://rrc.dannysrobots.co.uk for the Rex's Robot Challenge issues, I only scanned in the first 37 issues as this covered everything needed to get a featherweight going. It also took a very long time to do so if I had done all the issues I'd probably still be scanning them in now!

I believe the antweight articles are around Issue 49 or something like that. I do have those issues and would be happy to scan copies of them for uploading but it would be a few weeks before I could get them as they're at home and I'm up at uni just now.

As for whether or not they are still relevant enough, I'd be best leaving that to the more experienced antweight builders. I do know that the ant Ian built used batteries of similar dimensions to AAA cells and it used off-the-shelf radio servos for drive, whereas a lot of ants today have proper geared drive motors, speed controllers and lithium battery technology. But I personally reckon the guide is still useful for making a competitive antweight.
