On a big mono like this you want to run a lower kv and use larger props that align with gas boats. So 60-75mm. I would shoot for 20-22kRPM loaded with a KV range between 580-650Kv. I use a more conservative KV calculation using 3.7V per cell under load and multiply by .85 to take into account average motor efficiency.
The TP5670 would be a good choice. A 10D is on the higher KV side, a 6Y would be ideal but it's a special order based on what I see in stock today.
