scorpion 5035 500KV

[Fluid]

You still gotta watch your amperage draw. I was thinking more like 8 s but 10 s is cool too. Theres a 75mm 124mm pitch out there and its cnc'd

Not nearly enough Kv to run 8S on that motor, it would be terribly slow. Why this fixation on CNC props? Aluminum CNC props have generally proven failures on gas boats (poor design and too soft), and gas motors have a lot less overall torque than an FE does. Like Howard says, stick with proven gas props with high pitch. No need to reinvent the wheel here.

Hi guys

Think Fluid is on the money here - will put the 5035 500kv towards another progect its also to big 60mm Dia - or get rid of it!!!!!

I am going to try a 4035 800kv Scorpion - have made a water cooled motor mount and will try a 1955 or 1655 somthing with a big pitch

Fluid youre wrong nothing is too slow if you got the right prop

[Xfactor]

sorry I disagree its all about the pitch speed.

[Xfactor]

The props im talking about are proven gas props. But anyway no time for a drawn out debate. I heard this wont work that wont work watever. The best tell all is try it.

[Rumdog]

Absolutely not! That's not even 15000 rpm unloaded. No prop on that motor with 8s will get any boat near 60mph.

[Xfactor]

what up with cnc? there more right and exact the fixation is being able to acuurately design a prop for a motor. You can machine other materials besides soft aluminium.

[Xfactor]

who said it had to do 60 and with a designed prop it will do just fine . Before you load up Im done.

[Rumdog]

Show me proof that this will work please.

[Xfactor]

Im aware of the math just like you are .

[Rumdog]

He wants to go fast, right? Anyhow, seems this motor's out of the question for his rig, so it's a moot point. 8s on that motor, in ANY hull will not be very fast.

[Xfactor]

thats easy design a prop with the right pitch u can prove it to yourself

[Rumdog]

Ohhh, I am a prop designer now? Is it worth trying to design a prop to work just to run this motor on 8s? Nope. Sorry.

[Xfactor]

U read something and make it my gospel get over man. I was only trying to point him in the right direction. He should just do what you say your right man.

[Xfactor]

I dont know what you are other than a antagonist but anyway .See its not that serious for me to be rite all the time so you got it king boats. Take a load off.
