I know there are a lot of threads about different upgrades but I'm looking for a specific shopping list of what I need to buy to make this work. I currently have 3S LIPOs.

I have heard the Leopard 2860 motor. Which KV do I order?
SeaKing 120 ESC - this seems straightforward
Which prop?
Which collet/connector do I need to connect the Leopard motor to the stock flex shafts? Or do I need different flex shafts?
Any part that I'm missing?

Thanks for the guidance.
