I should have it built by then, its just a case of if my car will be able to make it that far. Its being a bit of a t**t at the moment, and I suspect it might be dead by then. But I'm starting the build as soon as AWS 41 is over, so that should give me plenty of time. I went for the lower kv as I was thinking of going direct drive. If I do end up going for a pulley it will likely be 1:1, or something very close.

I could pick you up on the way through if you want?Comment

A nice POP, best of luck with the ESC hacking.
I don't think direct drive is the best option in this weightclass due to the greater forces that you mentioned, though it may be worth trying it to see (just stand well back incase it fails). As an alternative to timing pulleys, what about mounting the brushless motor vertically, attaching a wheel to it and running friction drive?
Don't think it's been done in that orientation before and doesn't call for as accurate a setup as traditional transmission methods; just have the motor mounted to a hinge that's sprung in such a way that it keeps a constant pressure on the disc (to account for wobble in the disc or wheel). You can then adjust the speed/ratio by varying the wheel size or how close to the disc's centre you put it.Comment

Progress has been slow, but I've finally got Enormole all wired up and working. I'm not the best at soldering, and I'm pretty slow at it, so I had to clear an entire evening to get it all done. The worst part was getting the external relays on the electonizes all wired up. It seems like such a waste of time as I know I'm going to use TZ85as some time in the near future, but I guess I need something for the interim. I was going to solder new wires onto the motors, but lost patience and just left the standard drill wires on there. Maybe that'll be a job before the next event. At the moment I just want to get it ready for Newport.
It's starting to look a bit more like a proper robot now. There's still loads to do before Newport though. First off, the 3 cell battery is geting replaced. I fancied a 5 cell, but looking at its current performance on 11.1v, I dont think 18.5v is necessary. I may just get a 4 cell pack now. Judging from the video, what do people think?
Then I need to build a case for the lipo. Am I right in thinking that we now need a metal cover all around the battery? Is 2mm ali going to be enough? I really don't have the tools to do much steel work. I also need a link, fuse and LED, but these should be easy enough to sort. The side panels are already cut and just need screwing on. Same goes for the scoop and front wedge, and it'll be done. I'm not expecting much in my first event, a wheel came loose even in testing tonight. But I've learnt so much already, and I've not even made it into the arena yet, so I'm hopeful for my 'proper' featherweight, which will be started at some point after next years FW championships.
It doesn't drive too bad for something I've kocked up in a few afternoons. It certainly had a bit more punch than I was expecting (hence potentially dropping the 5 cell idea). But I guess you can't judge much in a small space like this, I'm sure it'll seem underpowered when it comes to a real fight.
