The Riptide Beetleweight Chronicles

[Flag Captured]

Adventures in CAD (alternative title: its an abomination, never cad again matt)

So, I finally decided to get off my backside and actually design something up. Originally a hexagonal Full Body Spinner, I mentioned it to Haz, and then jokingly mentioned it could be a triangular one because 'that would be bizzare'.

And thus, Bizzare Love Triangle was born. With a name suggestion like that, I couldn't not do it haha

Excuse the awful Cad-ing by the way, I'm naturally a radio/video sort of person so designing models of things is alien to me, and it shows... http://i1355.photobucket.com/albums/...ps84207eec.jpg

It's powered by this battery http://www.hobbyking.com/hobbyking/s...Lipo_Pack.html

Drive is a set of 1000rpm gearmotors (ebay ones) with Botbitz 10A's, so pretty standard. No 4WD but 2wd with casters because weight and space is a problem.

Chassis I think I'll make out of 1/2mm grade 5 ti because that's light and what have you. Outer spinning disc and pillar in the middle will be aluminium of some kind. Hopefully 7075 or Alumec, but I'll see what price comes out at for that, considering I'll have to have it CNC'ed...

The weapon system is suspect to change, but this motor http://www.hobbyking.com/hobbyking/s...00kv_560w.html

and about a 2:1 reduction should get the outer shell spinning at about 7000 theoretical, probably 6000 actual. Or less. Either way, it's a large and heavy shell, it'll do damage at even 2000 rpm I reckon so it's still doing alright!

Now, the biggest problem I have at the minute is that this thing is literally huge. Outer diameter is about 380mm and that's pushing feather territory, May be a bit too big but I'll have to run it all through solidworks or something to figure out how much it'll weight. Guesstimations say it might be a tiny bit over, in which case I'll just cut into the shell a bit more, surely must be some weight to be saved there.

But yeah, new beetle build, should be fun and I'd like to get a FBS in circulation because despite the impracticalities for actually winning (the lack of srimech) they're hilariously fun to watch.
