Good stuff mate. What did you end up using as a link in the end? Also get like a magnet or something and see if the mystery metal is magnetic or not to see if its a steel or aluminium. It looks aluminiumey to my eyes.

Correct, it was aluminium. I can't believe I didn't think to do that >.<.
The giant black link still is an option, but I'm putting the thing together before I worry about wiring and such.

Bump

May be about a month late, will update with a picture post when I get chance, but the thing worked, it did fly, very far, and drill batteries aren't too bad. Surprisingly, no damage whatsoever (apart from a missing piece of acrylic I bodged another of).

Next project is a Beetleweight vertical spinner. I'm currently browsing brushless motors and eyeing up some 3S LiPos, and am just wondering what everyone else runs in their spinners? I already have a sabretooth 2x5 and two 1000rpm eBay motors, so am starting to draw up some sketches (again, will show soon).

Triple Post but:

The bot in it's final form. Uses the one amp drill battery, a sabretooth 2X25 (Under the fan) and weighs 4.1kg.

Sadly, I left the beetle sketches in France, but I will draw some more up to show.

This is awesome!!!

[Tashic]

Cool!
Some one should organize a wooden robot rumble!

Could be fun.
Heh, it'd be protective gloves mandatory, nobody wants splinters.

I have a wooden robot I could bring along

[Mega Masher]

Me too

Dad decided to order a 1300mAh 3S lipo even after I told him I didn't have a proper plan yet, so I guess I'm using that, plus one of these probably:

Will probably be the turnigy. Looking at some 40a escs also.
Will keep you posted on my progress.

The stuff's here:
Includes a 1.3 amp 45-90c nano-tech, a 1400kv 2826 turnigy and a 40a ESC, plus two eBay 1000rpm motors, a sabretooth 2x5 and a dx4 receiver. Please note that the wiring is by no means final, its only a test rig.
No wheels yet, but any recommendations? Looking at either smallest banebots or small foam wheels.

I'm now looking at 62mm onroad rc tyres that should arrive in the coming week.

I used 80mm selfmade wheels earlier (70mm hdpe circles with bikethread on it)

In both cases I use these to connect the wheel to the motors:

I use those 12mm hex adapters on my beetles, make sure you locktite the threads or they will fall off lol

[Fathersplat]

Thanks, will take a look.
Different motor now, how do people mount their brushlesses? I see it has something to do with having the shaft at the other side, but that's all I can guess. I've never had a brushless to play with before, as you can tell.

Okay, I admit it. I got lazy. Being involved in a semi-esport for the past two years has eaten a lot of my time away from other hobbies. I still have everything, it is just gathering dust at this point.

After visiting insomnia to meet with a few friends I was told by a good amount of roboteers to get back into this vastly-neglected past time of mine, and I think I agree, I have to do it. I just have to.

Two questions, where can I source machined parts and wheels from for beetle/featherweights, and how much do they typically cost? I'm not confident in my own abilities to search for this stuff as so far I have found no real answers.

Lastly, I haven't been completely idle. I still mess with lego from time to time, these being two recent creations, both kept under 500g in weight:

They're quite ugly but I was rusty with my building techniques so forgive me.
