ESC capability question

[hyrulejedi86]

So another forum brought up a good point that I was wondering about. We know that ESCs run cooler and longer when run at full throttle. So, how does turning the training mode on the Spartan affect the ESC, wouldn't that smoke it eventually, running at 50% all the time?

I figured someone here might have an idea plus we've got the chicken to maybe give some insight.

[Midnightsun]

I read that also and would like an answer from the chicken or anybody at Traxxas.

In the specs, it shows different modes available on the programable ESC. If I were to run this boat most of the day on "training mode" which basically equates to 50% throttle and 15% reverse, will this cause any issues?

What does "lifetime electronics warranty" mean? Would this cover the esc if it did blow?

The nay sayers claim you will have issues with reverse as the drive wire will unravel in the long term. Would this be covered under warranty if it did?

Can these programable settings be used with lipo or are they only recommended for the lesser power output Nimh?

[filmmaker]

good question about warranty running in it on 50%
not sure if it will hurt anything running in that mode??

but running the flex shaft in reverse could possibly unwind the flex shaft over time in the reverse is used?

[hyrulejedi86]

It was said though that running in reverse at only 15% probably won't unwind anything as that's pretty low. But time will tell.

Here's to hoping that CHICKEN chimes in! :)

If you get something cought in the prop and try and reverse it out, it will unwind the shaft even at 15% throttle :(

I think this is why they limit it to 15%. With so little power available it would stall as opposed to unwinding or damaging the cable assuming something stuck the prop. There was also mention of the boat taking on water if you reverse it but again at only 15% it ain't going anywhere fast. Real boats back up and don't sink. Only difference here is the scale. Real boats also limit the power in reverse. ;) Really sounds like Traxxas knows exactly what they are doing.

Hello Chicken!!! We need real solid input here.

sounds like you have never owned a FE boat
running them even at 15% power with the prop stuck up, it will unwind the cable ;)
and if the hatch is not taped good it wil take on water even at 15% power ;)

Easy-Access Hatch
Spartan’s hatch is secured by a single body clip and removes in seconds for fast and easy access to the hull interior. No sealing tape is required, and a specially designed drip rail in the hull channels away any water that washes over the hatch.

I catch you a lot typing the comment "sounds like you've never run a FE boat". It comes off sounding very condescending like you're all high and mighty since you make it sound like you run these so called magical FE boats. For the life of me I can't even figure out what FE stands for. You've added comments to my posts in the past and you said the exact same thing. You can bet that most people on here probably won't have experience with world record, 100mph strictly racing boats because Traxxas doesn't make them. These super high power "FE" boats you talk about can be in the thousands of dollars and the Traxxas boat is lower budget RTR. Lighten up on us and just continue to be apart of this forum and share your extra knowledge with us when you can.

Thousands of dollars?
not even close! You don't need big bucks to run fast with FE just the right parts :D
I've built a few FE boats for under $400 that will run mid 50's
the thing with running a wound cable backwards it will loosen the wind and eventually damage the cable
best thing with a high power boat is to never run it in reverse
there is a lot to try and learn with FE boats and burning things up is so much easier with them ;)

oh and the 100mph boats I will leave those to the guys that get those done
that's a little fast for me, I hope 65mph very soon with one of my builds :)

I would love a close up of this cool hatch :D
taping gets to be a pain with boats:wacko:

This is why so many of us are interested in this boat. Traxxas has done the testing. Traxxas covers it with a rock solid warranty and Traxxas has dealers everywhere to get parts when we crash or sink it.

The way I see it is nothing will burn up, blow up or unravel. If you build your own, it is trial and error and yes you will fail time and time again until you get it right and even then when you think you got the perfect setup it you find something else wrong or unreliable that needs fixing. I am sure Traxxas has already burt and blown up several versions before finally getting it right. I think most of us here want to simply enjoy the boat on the water and not work on it constantly trying to get it to run ;)

Take a drive cable in your hands and try to unravel it with just a slight force using only your fingers. Did it unravel? I doubt it. Well that was 15% power. Now try it with pliers on each end. Did it unravel? Probably. Well that was 6S lipo on full power. You make it sound like a drive cable is made of yarn.

Wow, a drive cable made of yarn?
not so, they are metal and they can unwind even just a tad will hurt performance of the cable and eventually fail under 6s power at 50mph down the straights

remember when the ERevo came out and so many users under normal conditions had failing ESC's?
Why? well we really do not know, they are on their 3rd or 4th version now trying to get away from issues they were having that they did not under testing
we (consumers) will test the limits of everything Traxxas puts out, we are the best RnD they have :D
some people for some reason get all bent when you suggest something or say this may not work:wacko:
give it time.. running FE boats is a whole new world
even runtimes, people want to argue and say this boat will run 30min or so at 50mph.. not ..
maybe 6-8min depending on what lipo cells and prop are being used
and even that got into an arguement with users who have never had a FE boat and understand these things pull lots of amps, and lots of amps is lots of constant power
FE boats are amazing, and I will be getting one of these Spartans and putting in a different motor and push the limits of this hull
I hope to see mid 60's with mine on 6s

and by the way, this boat depending on prop could have peaks of 110amps x 6s is over 2400watts - 15% = over 360watts.. that's still a lot of power in reverse if something is cought in the prop
that's more power than some .15 size nitro motos ;)

[Midnightsun]

Nobody seems to be getting bent except you. The manufacturer claims it will work by stating this.


Three programmable drive profiles:
Sport Mode – 100% FWD / 15% REV
Race Mode - 100% FWD / No REV
Training Mode – 50% FWD / 15% REV

You are claiming you know better and that Traxxas is wrong? Let's see, who should we believe? Unless Traxxas steps in here and says they screwed up, I think I will stick with what the manufacturers has in writing.

[cooleocool]

1) Stop this pointless bickering, please. Speculating about what a product will/wont do before it has even been in the hands of consumers gets us no where--unless you consider earning yourself warning point as an achievement, that is. I haven't issued any yet, but if I see the bickering continue (trolling), I will not hesitate to issue them.

2) Since filmmaker didn't answer the question, FE stands for Fast Electric.

3) I agree with Midnight sun when they said:
It comes off sounding very condescending like you're all high and mighty since you make it sound like you run these so called magical FE boats.This needs to stop. There are ways of saying things so that you don't offend others. Please be more selective of your wording.

Let's all just get along... please.

And now a word from our sponsors... The fact is that Filmmaker has a whole lot more FE experience than I do. I could make up answers for your questions but then he would just shoot my answers foll of holes. Our engineering department really is extremely secretive so it all comes down to patience.

Bro, I would love to be a fly on the wall in that engineering department
FE boats are so addictive :lol:

I really cannot wait for this sweet looking boat to hit the shelves, so I can grab one of them and hit the lake with my lipos and see what she can do,
and if I smoke something in goes a bigger esc and a CC1520!! :cool:

Call me crazy but I would rather use sealing tape as well, just in case you flip it over and either have to swim or paddle out to it. I am sure its fine for water washing over the hatch, but upside down is a different situation.

To answer your question, FE stands for fast electric..... sorry just noticed cooleocool answered the question.....my bad

i saw someone mention something about runtimes on this titan, and i just wanted to clarify that they will not be near the runtimes you would get with the same batteries in a car, boats have a constant force pulling back on them, its like tying a weight to the back of an rc car

Like a very big rock! :lol:
a boat of this size, depending on the prop used can and will pull and average of 40-50amps and possibly more :)

[Freelanceshots]

So whats going to be the best after market metal prop for this boat if you leave everything stock and run lipo batteries? Two blade or three blade? Size? Model number?

Also, I though that's what FE might stand for as I googled it but I didn't want to suggest it not knowing for sure. Thanks for passing along that information.

[filmmaker]

well the boat comes with a 42x59mm so a S220 prop could be a good ugrade, but it's good so see just how this boat does in our hands before going out and buying props
http://www.offshoreelectrics.com/products.php?cat=Prather+Propellers
I do have a S220 that I'm going to try on 5s and 6s
but a S225 on 4s could work great for those with 2s packs
time will tell

[Freelanceshots]

I will be one of those running 2 x 2S as thats what I already have. Could you run one 2S and one 3S together. I see that you mentioned 5S so this is most likely what you meant. Had to send one of my 40C 2S packs back to Venom for a warranty repair so I'm most likely going to get a brand new in return so I might be able to trade up at the local hobby store.

I use 5.5 bullet connectors and have run a 2s and 3s pack in series and it worked awesome in my UL-1
I never did a gps run, but I would say high 60's, and it was just plain nuts :lol:
I will be running two 5000mah 5s packs in series with my Spartan

10s, are you planning on changing the ESC?

He would have to. No choice.
