WARNING doing so will straight away void your warranty and Arrma shall not value their '2 year warranty' as under their terms and conditions the ESC's must not show visible signs of wear, of show proof the ESC's have been opened or tampered with/altered in anyway.
FACT: you can reduce the kraton weight by a full kilogram (2.2lbs)
don't think so...
Had to send in my ESC a week ago. I asked support if i can leave on the green castle connector which i am using.
answer was like (translated):
just send it in as it is. if we gonna replace the ESC we solder it to the new one, or at least we send it back to you.
Each individual Arrma 180a blx 6s esc that is sent back with the purchase receipt and date is decided upon, case to case by Arrma technicians as whether the user is at fault or dodgey manufacturing. Not everyone will get their esc back 100% read your warranty that came with your Arrma car. If you own one....
1kg? 20% of the original weight? seems a bit optimistic to me... have you some weights for the individual parts?
