Up to rev2 already...

Image

The original was too wide,the wheels were the wrong diameter,and the lifting arm was not long enough,only enabling the servo to move through 45 deg,enough to lift,but probably not enough to self right. :oops:
Also I am trying out some new tires...

Image

The tyres I usually use are on the left,and the new ones are on the right.They are pretty soft solid rubber.They weigh double the old ones,at 4.8g each. 29mm dia,and 14mm wide.
They are again paper handling rollers from printers.

New chassis due next Monday.

I always put masking tape on cabon,as the edges rip and tear easily,with tape on both sides,it stops the ripping to a degree. Try on a spare bit until you get the knack.
Also,a good tip is once you have drilled it,lightly sand it and then put a bead of cyano (super glue) on your finger,and run it around the inside of the hole,it seals the edge,and stops it from catching and ripping.
Here is a pic of 10mm holes drilled in 1mm carbon...

Oh,also Harry...
Make sure you put a block of wood behind the carbon you are drilling,or it will rip for sure,as the drill bit comes out the other side. :)
