it's only one and it's visual.
my friend just got his V3 today and i must say it looks very nice, cant run it yet untill he gets a motor though
BUT,
both the phase plugs and the battery input plugs are VERY disturbingly close to the heatsink.
i know this is a little issue and has caused some accidents before.
like it's scary close, maby 1mm in some places.
to try and prevent 200+amps going through the heatsink on contact we have placed some tight fitting heatshrink over each bullet socet to try and prevent any arking should the bullets move a tiny amount.
but i mean it, very scary, IMO i think that castle should continue making the V3's but just give a little more head room to the heatsink and bullets.
