HELP Aquastar 240a esc

[T3tsaya]

I thought 240 was high

[T3tsaya]

So what if I want to be going mid to upper 60s what motor and kv rating should I get

In a typical 6s set up 240 would be fine. With that set up you were easily spiking over 200 a on start up and hard acceleration. 1600 kv is about as high as would be considered reliable for 6s. After that the margin of error starts to reduce rapidly. When you run 6s on a 6s esc you have to take other things into account that aren't as crucial for 4s or 2s set ups. You should be using an external bec and timing and pwm settings need to be correct as they contribute to heat. I would recommend you spend some time on you tube and see what others are using and what speeds they are reaching. I saw a stock Spartan on 6s for the first time on the weekend and it was already very fast. But a motor in the 4082 size and around 1500kv should produce as much speed as that hull will handle and still be reliable.

Okay cool sounds good thanks
For the help now here's a question I have a river fighter cat coming I'm the mail I have a m545 prop and a fightercat outrunner 1600kv and a seaking 180 but I want to be faster what motor prop combo would you recommend for my seaking 180

[Rocstar]

Which 1600kv motor do you have, 3126 or 3730? The Rivercat is a light hull, and setup correctly a 3730 1600kv on 6s should put you in the low to mid 60 mph range. How fast do you want your 32'' hull to go?

[T3tsaya]

Lol 70 would be great but I hear cats run better in slight chip so I was think mid to upper 60s maybe a x447 prop and te outrunner is a 3730 but it runs warm because its an outrunner I'm currently running a octura m 545 and when the water is right I'm probably very high 50s and maybe low 60s but I want to be mid to upper 60s

I have a few outrunners. They can be great motors. Again just a bit of care on how its used. An outrunner will always be a few degrees warmer when you bring it in than when it runs. Once the air stops flowing the last bit of heat stays on the metal longer but that's a good thing cause it gives a bit of a safety margin. The other factor is the volume of air in the hull. Once there is no more cool air then the motor is obviously going to stay hotter so the faster the boat is going the more heat the motor is making and the shorter your run times should be.The other thing with them is the amp draw. A lot of people seem to think they have more torque and draw less amps. I disagree. They have more torque for sure but that's mainly due to the extra moving mass. More moving mass means more amp draw. Doesn't matter if its on the propeller end of the shaft or the motor end. More load means more amps. Just something to keep in mind.
