Mean Machine 1717 4s2p M447 Kids set up

[millzee]

I tried posting a link last night on my build thread but it was banned in loads of countries due to me trying to add a little music. I have remade the clip with no music, should work. I have a long way to go to get this boat running well on 6s but I'm really happy with the kids set up, as it say's in the title, castle 1717 1580kv, t180 on 4s2p running a m447 prop. It gives cold temps and I get nearly 3x 5minute runs on 1 set of lipos without stressing them.
Please take a look and feel free to offer any additional advise.
