HI Mike
A valid and important question is what sort of speeds you are after as the faster you go, the shorter the runtime. If you are looking for 60 mph plus you are only going to get 2-3 mins. If you are looking at fast scale speeds the runtime will increase but much more than 5 mins would likely be unrealistic on 10000 mah. Any info offered up will only be a ball park as the drives you are running will have much bigger energy losses over flex shafts. You may find that going to 8s will be better depending on the speed you want and the props required.
Can we assume you are planning to run 10s 10000mah on each motor?
Are the drives 1/4" or 3/16" shaft? This will determine what prop sizes you will have to work with, i.e. 1/4" shaft means you will need larger size props 65mm and up.
There are a few guys with big hulls that may be able to get close to what you are wanting to know.
My own biggest is a 45" hull (ex gasser) running a TP 56110 650 kv. On 10s 5000mah and an X455/3 speeds are around 55 + mph and use around 3000mah for a heat race (I only race it). I have a 42" Osprey with a TP4070 440kv that runs for 20 mins on a prather 245 and 12S 20000mah, which I use for offshore endurance racing.
I know my boats are a fair bit smaller, but you do have the room to put more batteries in that hull for longer runtimes if you wanted.
