Hi there, I have question as to what Amp of ESC this Turnigy 500 H3126 1600Kv motor would ask for at full power. I see on HobbyKing recommended 70A ESC. But is the demand alot higher in a boat than a copter?

I am wondering if anyone could give me some advice. I am new and building a hydro. What would you guys think this Turnigy 500 H3126 1600Kv would ask for in a 31" long 16" wide hydro?

The batteries used are 2 x 5000mah 5s 30C batteries. Being it is twin motor with water cooled mounts.

The props I am using are either a X640 type or X440 with solid shaft drive.

Any advice would be great so I do not create a speeding fireball on the water:scared:
Thanks all!

I ran a venom p1 with the sane motor on 5s with a turnigy/seaking 90a esc with an x640 prop with no issues. I would prob go with the 120a though.

that 70a they call for is for heli's though its pushing the threshold i have a cc 75a ice in my trex 500 it isnt piping hot but it could be cooler. then again 500 heli's are known as lipo puffers lol

Exactly! It is good to be different sometimes. It is freaky looking, That is what attracted me to it. And the modification possibilities. I am changing the hatch look too ,, The boat is mainly a outrigger in my opinion. But still. Dare to be different!:sneaky2::wink::rockon2:
