Spring time is coming so I need a new boat to play with. I was looking at mini boats, mini c,v rio and some others, and I decided on the mini rio. I was also looking at some other posts and decided to go brushless.

What do you think of my set up?

For a battery I'm going to get a 3s 20-30c 1200mah lipo

I know since I'm getting a more power motor I will need a thicker flex cable. Is .098 good?

Can I use the stock tube or do I need a new one for the cable?

Can I still use the water intake system or do I need to add a Y harness and more tubing?
Whats the best size prop to use too?
Is there anything else I should either add or change?
Thanks for the help.
