Im not familiar with the Tamiya connectors, but do ensure they cna handle the current you will be facing (wich you find with your wattmeter).
A to big propeller is disastrous because it can overload motor and ESC. And ESC is ususally the first to give in, and it gives in faster than you might think if the prop is way too big.
So keep an eye on the amp draw on your first run
