Spartan ESC

[martin]

Thunder Tiger have just launched a new cat artr in the UK, Its 46" long with a 60esc & OBL motor whatever that is. Wouldnt touch it with a barge pole.

NO WAY, you are joking right? Holy Carp, who is in their Tech Dept ? Smoke on the Water!

Well, I just took a look at it and well, same old, same old...

It says in the instruction booklet that it was developed in co-operation with hydro world champion Jorgen Anderson.

They did put a larger motor in this than the mono, that was a 36mm outrunner. This one has a 43mm outrunner but, still only a 60 amp Seaking esc....

Runs on 4s1p and instructions say MAY reach 30 mph.

Uses captive Asian style square drive flex shaft that forces you to remove the strut each time, errr, or as it says only every 5 runs

Its kinda funny i thought it has an apt name, Desperado Offshore Racer. They have a video of it running. Looks slow. Martin.

makes ya wonder why Tim Roberts,the boats so called designer,doesnt work for Traxxas anymore.he bailed awhile ago even before the boat was re-re-released.

mickvk asked about the circumstances of the esc failing.

How about at there were No initial warnings from the esc or the receiver that the esc was about to catch fire as well as sending a sudden pulse to my batteries which sent them up in smoke as well. I followed the instruction booklet that came with it word-for-word and look what happened. It sickens me that I see all these videos on youtube and on google of people having to pull out the stock components and upgrade the motor, esc, rudder and tubeing just to get the boat to work correctly without frying the esc or overheating the motor.
Shame on Traxxas for not thinking this project through and for not testing the boat thoroughly.

My heart goes out to all those Spartan owners who are dealing with this bull*!***!***!***!** like I am.

Im 40 and have been in RC since I was 13 and this is by far the worst heart wrenching experience I've had to this date.

Boat was sent back well over 2 weeks ago and they have not contacted me as of yet.

All my components were stock, the only thing I purchased additionally was 3S 3400mah lipos from a local hobby shop that recommended them. The batteries are Racers Edge which are well known batteries used in a wide range of rc vehicles.

I guess my question was too vague:

• How many minutes were a typical run for you?
• What were the motor, esc, and battery temps?
• How many amps went back into your packs?
• Where you running loose or tight?
• What speeds were you getting typically?
• How many runs do you have on this setup?
• At what point during the run did the failure happen?
• Have you measure your amp draw or ripple? The packs you ran did not meet the mAh requirements in the manual.

do you relize the stock packs are 3000mah?
reason they say bigger is for the runtimes!

[Brushless55]

Well, I hate to say... o.k. maybe not hate but, I have to say i told you so.

Waaaay back when they were first promoting this boat, I warned people.

Sometimes it's good to listen to those that have been doing this for 20+ years now.

You can't expect too much from a plastic boat with an XL 2 pole motor, it just isn't enough.

I offered my technical experience to Thunder Tiger and they basically told me to F- off.

How many people own a TT OBL ????? I think they may have sold about 200 of them, if that.

This boat was only a hair better, I won't say which hair .

one is me, but I replaced the 60amp esc (for sale by the way) for a T180 and the stock motor for a CC1717

Now yer Talkin' !!!

[Brushless55]

Now yer Talkin' !!!

Heck ya Ray!
this is the mount with one of my CC1717 motors ready to go into the OBL

Sweet! Is that Green hull, if you have aa green one.. is it 39" long, hull only?

I wanted that hull, just hull only but, could not get one.

Great for Q mono! That motor should rock & roll.

Back to the thread.... what was the topic?


Ohhh yeah, the Spartan.....

Of course I did but run time is not in fact the only that mAh capacity affects. When the mAh rating is low, voltage sag and ripple increases especially at higher loads such as a 6S setup resulting in increased chances of an ESC failure... And it's a reason that an ESC could fail electronically without overheating....

so the spartan comes with 3000mah packs
these packs only put out 30amps cont
people are running the stock packs and having issues and some don't, some are running 5000mah packs and having more issues, and some even are running 6500mah packs with issues still
the so called ripple is not what is causing the issue here

that's the one bro!

[Make-a-Wake]

Wow Brushless..............That is one good lookin boat there! Big ol' wide thing too! So 1717 going into it? I feel a 60 mph boat coming...................
