Planners Beetles

We are hoping to have a drum bot for Russell and a disk for Jake, jakes disk will have to wait till next comp though. Not enough time.
its still 90% paper though but we do have some actual parts.
very very tiny parts

fingertech spark motors 83:1
2 amp controllers
1ah 40C "zippy" cells from hobby city 3 or 4 in the bot.
some turnigy brushless ESC from hobby city.

interesting motors! i thought those ones were planetary.

was always under the impression the spur style were inferior to the planetary kind given the same size, but thinking thats not the case anymore.. if so then all the better for us all because the ebay and jaycar ones have a similar gearbox to those too Smile

lookin gewd.

I reckon its weaker than planetary, but at that size can you imagine how small the gears etc would be?

Well the same/similar wheels stood up to scissorhands so I'm not too worried.
depending on weight they might get some foam or something

I probably just missed them Smile With that design, don't builders usually have to add a tail to make the bot stable?
