10S Pursuit

[Rumdog]

Well, I can tell you that a Turnigy 180 can take the abuse of a Neu 1515 1y running 5s. I have been running this setup x2 in a twin cat for about a year and a half without issue. A lot of rpm, yes. However, the motors and speedos have been excellent.

The ESC supplies current, but it does have limitations. The only specification in the manual for that esc is an RPM limit of 32,000 for the far more limited 12 pole pulse width modulation rate. The 4 pole castle on 10S will have no problem technically. Nor will the ESC.

I bet you'll get some cavitation running at that high RPM but by all means try it, measure it, have fun, and let us know the results.

The controller doesnt care at all what rpms the motor is running....it only supplies the voltage.

I assumed the thread participants knew i was meaning that "within reason" and within the parameters given..........which is a 1521 1.5y on 10s. Bottom line is it will work.............

[Flying Scotsman]

Almost 40,000 rpm......motor won't last long....should be fun for a few minutes though...

I would say 60 seconds.

I would say 60 seconds.

You didn't include a basis, that would be useful.

[Flying Scotsman]

A motor at that rpm is only good for a very short time duration and setup as stated, unless you want to replace it and the ESC after a few long time runs.

Assuming begins with 3 little letters.

Reasonable parameters for an electric motor in an FE boat is not 30,000+ rpms. Those are SAW type setups. The owner will destroy his electronics eventually but much sooner than under a lesser voltage.

20,000-25,000 RPMs are more of a standard for setting up FE boats.

If you want to make your motor and controller last use less V.

Yea.............figured that out on your own...............?

No, you are incorrect again. My father used to tell me that.

But as I can tell by your posts you are almost omnipotent. Must be difficult for you to work in a group.

[Doby]

I just want to see the video of the (short) maiden run.

[Flying Scotsman]

2 seconds, I would think?

[Rumdog]

You guys are great. Nobody else is allowed to break your rules. Obviously it is a higher than norm rpm. So, it must be off limits. Did you see my post about a twin? Do you think I am lying?

[keithbradley]

10s is a little on the high side of RPM range, so you will definitely want to run a small prop. It will be very easy at that speed to over amp the esc. I think you would probably like that motor more on 8s-9s. You could get plenty of speed without having to undersize the prop too much. As long as you stay small on the prop you shouldnt have a problem though. In my opinion, saying it will only last 60 seconds, or 3 minutes, or whatever, without know ing what prop you are running, is a little silly. I run the 15 series Neu motors in my road cars at close to 60,000rpms, and they work fine for me. Actually Im currently running a 1717-1y on 9s in my 2 speed 1/7th car at over 100mph with no problems.

[LarrysDrifter]

I say start at 8s and prop accordingly,then work your way up to 9s then 10s and check and record temps,amps...etc with each voltage and props,then make your decision on what you want to run,then decide if you care about the longevity of your components if the voltage of your set up is higher than "normal" or rpm is higher than "normal"
Thats my opinion.When it comes down to it,do and try what ever you want.Screw other peoples "rules".

Thank you for all the comments!

As i said, i know this setup is on the limit of what is safe.
But i run this boat twice a year with my friends on a weekend of racing and

The goal for the weekend is to have fun and hopefully set some records.

But i appreciate your pros and cons as i hope not to blow it on the first run
I ran this boat last year on 8s, but my crappy ESC (Himodel 200) broke down.

I will start on 8s and check for temp, then move on to 10s.

Btw. look at this: http://www.youtube.com/watch?v=yMs0ghSzBIc
