[BW] GR-01 Build Diary

Sounds like Alasdair is completely forked...

Weight wise the frame is a lot heavier than I'd like :P Its 900g or so. I need to replace the outter side panels with HDPE instead of alu, as those are currently weighing a lot, and it'll probably play nicer with other spinners then too. Gotta print out all of the nylon parts this week, mainly motor mounts and pulleys/wheels. Going to be experimenting with 3D printed rubber tires too.

Getting that in weight is probably going to be tricky with a 900g frame, Hyperion's was only around 450 and it is only 25g under the limit now it's finished. It looks fantastic though, looking forward to seeing it in combat.

I'm still alive!! I moved jobs, so low on free time recently, but starting to settle down again. Here is a belt drive test, its way too slack at the moment, gotta either get small belts or increase the diameter of the idlers.
Please excuse my TX screaming at me in the background, the battery was very low but I didn't want to swap it out before capturing a video quickly tonight

Belts need to be much tighter, so there is no slack at all, but aside from that... this is an amazing first build! Dat CNC!

Thanks I agree they do need to be way tighter. I'm actually going to keep the idlers the same and just order smaller belts, as I'm really happy with how its operating mechanically, I just ended up with a belt that's too large after changing some pulley diameters!

Once the drive is fully working and there is tires on the wheels, i'll start to address the obvious weight issue. Going to try and make the body narrower and replace the alu outer panels with lighter material. Then its weapon time

While waiting for parts for my feather to arrive, I put the new belts on this and gave it a test drive!
