the balance connector? has 3 wires going to it if its a 2s? usually the best way to replace any connector is to crimp them... otherwise have pre crimped ones and solder them in place of the original wires at the lipo... this obviously has many more risks, and unless you feel comfortable doing this, ...

there is a petition to bring battlebots to uk tv... the people over at battlebots have confirmed that 20,000 signatures would definitely get them in talks with uk broadcasting companies... so for anyone that hasn't already seen this doing the rounds, here it is... http://chng.it/QZPk5Jhwpq it will t...

what esc are you using? does it have built in mixing or are you using your own mix via the tx?

if you switch the wheels around, they will sit a good few mm closer to the body each side... this may also help...

my cube is just some foam tile cut up and superglued together... its pretty accurate, simple and helps a lot with builds

if those are 32mm pololu wheels then i think 13cm is too wide to fit diagonally, however it looks like you might get away with it fitting between opposite corners... with 32mm wheels you can be about 110mm wide and fit the cube diagonally, however with the same setup you can be about 145mm wide and ...
