Traxxas Spartan

[mickvk]

It might just be semantics, but manufacturers have guidelines that they have to follow for saying Lipo compatible. Low voltage cutoff is considered reasonably necessary, so that's why they say the supervee 27 esc is not compatible. That's coming from the guys who have to warranty the stuff! :) If you are aware of your current consumption, you can run without LVC. Amperage is another consideration for the SV27l. I would say that 4S is probably too much for the stock prop. Amperage peaks to 75A - not good for the esc and actually it's 10% beyond the 1000 peak wattage recommended for the ammo motor.

back to the Spartan though, 2S is unusable. 3S is dog slow. 4S is drivable. If you have 2S, use two in series.

But that's listed as needing 2, 7.4v lipos always running 14.8v. With running 14.8v and having 5000mah what kind of run times will that yield?

[mickvk]

So someone please show me a boat that'll run 7.4v and 11.1v lipos. I've just read up on the ShockWave as well and they say it can't handle the 11.1v power without blowing out the joints in the rear. Is there such a thing as a boat that's RTR that can do what it's advertised to do? LOL Or what about a kit? Something that is ARTR that I can throw my Airtronics Rx in and set-up?

The shockwave is hot on 3S. 32,000 unloaded RPM. But I have one running 38MPH and it's a riot. Of course the stock ESC will not pass 132 peak amps. I don't recommend keeping your requirements down to the battery you have. Never compromise what you really want for what you can afford. You may have to wait out your budget problem or whatever the issue is and then get the right boat.

this runs on 3s

I have 6, 7.4v lipos and 4, 11.1v lipos. I'm hopping to not have to upgrade anything in terms of the boat or lipos I have on hand. So I'm just looking for the best bang for the buck. As of right now I'm really considering The ProBoat Miss Geico I love the look and don't mind running the 14.8v's.

That would depend on your amp draw. A function of throttle position, prop size and hull resistance. You can use this calculator to do estimations.

Spartan 4S, I would guess six mins. I target 80% of battery capacity though, that would be 4000 usable in your example.

Are you trying to say that a stock sv 27 with 4s lipo needs a smaller prop? lol. Not true at all. In fact you can prop up to a 45mm prop without incident. The esc is rated at 45 amps but in reality it will take bursts much greater, and is a fantastic FULLY waterproof esc.

Oh yeah.... Spartan sucks.

funny
some moron did a write up on the new SV27R who has no buisness doing such a thing on FE boats.. you can tell by the guys comments on the SV27R
the stock esc can take way more than 4s in fact I've run 5s on mine with no issues at all except more speed
some have run props bigger than 48mm on the stock motor and esc running 4s, and Darin Jordan was one who raced with his with great results
I love a CF48 on 4s with mine, and I will try a S225 and S230 next when things melt
this is mine on 5s with a S220 prop (bigger than the stock prop)
temp on motor was 105* and on the esc was 95* on a 2 1/2min run

[Joeyhatch11]

So it's now between the Aquacraft UL-1 or the ProBoat Miss Geico? Ideas/comments? I like that I can use the "easy pay" option on Towerhobbies and also get free shipping.

Wow, that's low man. Hey, I certainly have things to learn but you have to persuade, not beat it in to me and resort to name calling. Stay classy!

name calling
not you at all, but the guy who did the review of the SV27R could learn a few things from the guys here at OSE at how a FE boat should run
and I'm not trying to persuade you at all.. you have your mind made up on the SV

the comments from the SV review made the boat look lame when in fact it has proven components over and over
the SV has it's own class in many cities and they run stock everything but props
and they run some big props on that stock system without any issues at all
and most every FE user knows FE boats have short runtimes...
in my opinion, new to be boaters who would read that review would look for something else

I just hope that guy is not paid by Traxxas as he may give the Spartan Boat of the year
I'm still trying to figure that one out

interesting we have yet to se a review of this boat.....

Has anyone else noticed the Traxxas website is down for "maintenace"? I can't help but wonder if they will purge previous Spartan posts. I suspect the discussions over there may have been impacting sales. Odd-timing.

Funny, I couldn't help but wonder the same thing. They have been deleting selected posts all along, but you can't help wonder if they will take the opportunity to thoroughly scrutinize the Spartan forum and "weed" out anything that could be perceived as negative.

I guess we will know as soon as they get back on line.

As for hurting sales, they can't censor all the other popular RC forums on the web, which reach a much wider audience overall.

If they want to ensure strong sales, they are going to have to fix the problems to restore confidence in the reliability of their products.

What do you guys think of the AquaCraft SuperVee 27R Brushless over the UL-1?

[dag-nabit]

No Experience with the UL-1, but I have a couple of the original SV27's and they have been rock solid. They have provided us with hours of fun.

The SV27R with 2.4 gig radio and bit quicker motor should be a great boat. (1800kv vs 1500kv in the original SV27 I believe)
