the board attachment quota is quite stupid I hope it gets fixed.
as for your battery I am probably wrong so I would get someone else to confirm.
if it was 5,000 mah 1c it could take 5amps.
because its 50c it can give 250amps of power.
well more than the stall of speed 900s
before you do anything I would wait for someone to
someone check that aswell please
don't do anything yet Lewis :|
