Serpent Scoop: 1/8 scale electric onroad: 966-e (24/11/2009)
By: Ronald Baar
Linked to: Serpent 966-e

Scoop
Serpent has developed the 1st purpose made 1/8 scale electric onroad production car for onroad circuit use .

Its fully based on the highly successful Serpent 966 platform and shares the main components, full independent suspension, 4wd, belt-drive. The center section is now reserved for the electric components.

It features a purpose designed nylon bracket / holder for all components, like the 2 saddle Lipo packs 4800 or even higher capacity cells, the speedo and the receiver. The large high power BL motor is securely mounted on a sturdy alu motorplate between the rear 2-speed bracket and the alu radioplate support. Purpose made alu and/or steel pinion-gears, single speed principle.

All elements have been positioned in such a way that an optimal weight balance of the car is maintained. Charging and replacing electronics is very easy and accessable.

Silent high performance ….. incredible acceleration …..amazing top-speeds .....

Planned introduction: Mid december 2009

Serpent will also offer a Conversion set, to change your 960 or 966 into a full blown electric racer .... so you may just want to hang on to your 2009 car for this purpose.

i would like to see this in action maybe i would then get into 1/8th scale.

wow, serpent's on a roll these days....CATCH UP mugen..lol

No motor noise ... no fun

Don't forget another reason that we like nitro so much, run time although I could be completely off here since I am just going by 10th scale current draws.

So that puts us back at 5-6 minute mains. Electric has been stuck there for ages, and maybe it has something to do with the 8th scale sized motors or maybe it is just offroad but offroad cars can get 20 minutes of runtime or more depending on numerous things. All things equal, an 8th scale with an offroad motor (don't ask why I know this) gets about 5 minutes per tank in an 8th scale car and the same motor gets about 9 minutes in offroad because of the lack of traction and fuel consumption.

I can't tell for sure but I don't see a quick change system there for the batteries (even if I did, I wouldn't want to own even half an hours worth of 4s-5s? batteries for it at around 200 each)

Then again maybe this is a good thing for tracks that eat 3 sets of 37's in an hour long main. Electric, lipo and brushless have really taken a hold in the market with a product announcement as big as this.

maybe more LW more fast !
don't need take a starter , charge receiver battery , turn engine ,break-in ...

Ya, how are you gonna do a 30-45min. main with this? I mean a 5-8 min. run, then charge two packs for 45min. for another 5-8 min. run? Gonna need to have alot of batteries on hand....thats gonna equal ALOT of fuel as far as cost if you ask me.

You can do it triple main style like the 1/10th scale big races.

.....agreed....NOT interested in spending huge bucks for a 5 miute main....get em to run 10-15 minutes.........then OK...............

i wonder what the price point will be?

ya, if it can run for 15-20 min so 2 -3 battery change for an hour final is ok. But 12 batteries for one final does not look interesting at all. :eek:

can you make it a 2peed that is the ?????? I would like to know

If you can make an adapter on the motor holding the Centax gears, yes you can.

With the 1/8 offroad brushless is becomming populair but I doubt it will get the same run with the onroad.

I've seen Zippy Lipo saddle packs (7.4V/5700mAh), that should fit for $30 (2 pcs)
So 12 batteries in your example will cost $180....
4 Lipo chargers (5A max) will cost $140, so all in all less expensive then 1 good Nitro engine.....

Sure, if you want overpriced batteries from LRP, or any other non OEM manufacturer.....
I go for Zippy batteries, run them in my M18 also, have 5 Lipo's for the price of 1 LRP....

Doing a fast battery change in the setup I see them fit in the 966, would be difficult...
But I think with 7.4V/22800mAh or probably 14.8V/11400mAh (to keep current as low as possible) Runtime would be more then 5 minutes...... (educated guess)...

Guys....we all want to see this happen, but if you have some time, check out this thread on Rctech....there are at least 4-5 group of ppl testing the lipo/brushless motor onto their MUGEN KYOSHO and SERPENT for the past year......the 966e is nothing new at all. Basicly, these ppl already tested onto their MUGEN KYOSHO for the past year.....

The problem they all see is....batteries is not large/powerfull enough (current model)s to move a 1/8th ON ROAD car that will last more then 5-6 minutes with FULL RACE condition (comparing to the nitro on road with 2-speed)....do not even compare the OFF ROAD version to the on road, off road can last 20 minutes because it does not use full throttle on pathment all the time like On road...ON ROAD is a totally different thing and these guys blowing motors after motors, lipos after lipos, and still trying to find the best combination for these 1/8th on road conversion for a good 6-8 minutes FULL SPEED run (like a 5 minutes qualifier for nitro on road)...

These ppl also have big batteries support behind them (they are not using the $30 lipo, they won't work) with prototype MAH and high C Rating, Saddle packs or straight packs...etc. And they are still testing things out. You can also find videos of them in action....there are only a FEW of them does look promissing....and they are all running in 6S configuration with 2350kv or slower motor.

Thats why...I am wondering what kinda LIPO/Motor package that SERPENT is releasing or using to back up their research....apparently, 4S is really pushing it, for both the run time and performance wise...and running more then 6 minutes without blowing up the speedo or motor is really pushing it. Serpent DOES NOT sell the LIPO or MOTOR for this 966e. That means, owner has to buy what is available in the market. It might get the car to move, but for how long, and how fast...no one know.

GO thru the below link....you will find a lot of usefull information so you don't have to waste $$$$ for blowing up speedo, motor and lipo. (They did that all the time...). Also, within the thread, you will know there is no reason for CENTAX, no reason for 2-speed........MAY BE, you can keep the brake, but for on road...I think I will let the speedo do the drag braking job instead of a phyical brake like Nitro engine does...(remember, nitro engine cannot BRAKE itself and thats why there is a phyical brake on nitro version). And 15-20 minutes of a run time...it is a DREAM only (at least for this moment of technology of lipo/brushless motor). You can find all these data within the link below.

Not to mention...someone did a full carbon 966e looks even better then the original Serpent 966 itself.

http://www.rctech.net/forum/electric...nroad-car.html

4pcs battery !

Exactly! everything you tells is absolute true!
Been there done that..
I do not like the configuration on this new 966, 4s lipos will kill batterys, Esc and motor. 6s and 2000kv motor and low gearing is probably the way to go, add some nice 6S lipos of 5000-6000mah then you have 10-14minutes of runtime in 65mph range on large tracks.
Will serpent make people disapointed? I think so.
I will order the gear adaptor and the motormount for my 966 though:)

I would not say Serpent is going to disappointing us...at least, SERPENT stepped in and start their own project. I am just looking forward for them to reveal the whole project, especially that 4S lipo (saddle pack) that they are using, then the motor....and a video about a running 966e vs a nitro 966. If the 966e is only about 1 second slower then the nitro version 966...I would say they did a pretty good job.

http://www.youtube.com/watch?v=qZRqqyzB2j4

The above video...is probably the best running brushless on road conversion so far...of course, I am sure the E-kyosho or E-mugen here in USA are doing something as good or even better then that. But from what I can tell....with the current LIPO and MOTOR that we can buy...6S is the ONLY way to go if we want the speedo/motor not blowing up and still do 65 mph...

The above thread does go thru alot of data...for those who want to work on this kinda project, those info saves TONS of money and times.

To be honest....10-15 minutes run time is kinda high (no matter what you can find now for RC hobby)....I will take good 8 minutes HARD RUNNING without killing the motor, speedo and lipo....then I will be a happy camper (with today technology that is..)

To me it looks like the newest saddle packs which are 2S make this 966 a 4x2S = 8S set-up!....

http://www.rc-mushroom.com/product_i...ducts_id=16347

The 2S means 2 packs of 3.7v units. So the 4 blocks makes a total of 4S

Getting the same speeds I think more is needed than a common used 2200 - 2750 rpm/v motor, It will be in the range of a NOVAK HV which comes with 3000 up to 4000 rpm/v

the saddle packs I mentioned are already 2S/7.4V
there are 4 of them mounted in the car, which means 8S....

Nope that is not correcti...all the packs you mentioned above were all 2S 7.4 TOTAL, each block is 1 cell 3.7V...on Serpent 966, it used 4 blocks = 4x3.7 = 14.8V. Like the one below, times two.

http://rcmarket.com.hk/images/IP-TP2S6000V1.jpg

IF (I highly doubt that) they are indeed 2S each...then I am 120% sure they are not even a 2000mah each, kinda like the cell phone or portable handheld computer batteries....which has low C-rating and will blow up the batteries in no time, if using on the 966e.

This configuration were used by multiple groups of ppl on their Evolva and Mugen already...again, 4S just not powerfull enough.....yet.

Also, high Kv motor won't work cause 4S (14.8V) just can't deliver the power for that kinda fast motor and not to mention, to last 5 minutes without blowing up the speedo and motor....again, faster motor were also tried by these ppl and without using higher voltage/lipo...faster motor just won't get to that fast Kv speed. Remember, the amp draw of these monster are not even close to what it is on 1/8th off road, thats why they have been blowing up lipo and motor left and right by trying to find the right combination.

This 1/8th conversion is a lot harder then everyone think....you cannot say it works on 1/8th buggy conversion, or plenty of 1/10th 190mm were using 4S and why not using it on 1/8th on road....somehow, it is not that easy to get that work out....not even for good 6-7 minutes of run time. Converting a nitro car to electric actually is the easiest part afterall. Take off the brake system, the 2-speed, the nitro engine....it is alot easier then trying to fit the right compoinant into the car and can still run for 6-7 FAST minutes....

Really...read thru the above thread. These guys wasted a lot of money, time, speedo, lipo and motor to get to this point...and it is still not there yet.

You could try the Future XXL or the YGE 200 HV Navy or maybe the Castle Creations HV240.

The problem with ESCs blowing up is the driving style. As IC engines have very little torque you can give the car full throttle at low revs and let it rip. An electric car will just go to full amps andblow the ESC when you do this. The ESCs have to be limited to ramp up the power slowly. Another solution would be to fit a mechanical 2 speed gearbox to offload the low speed amps

We have the same problem with speed cars. If we gear them up too high you have to feed in the throttle very slowly

JA, ik zie hem!... (na die foto van Solara)
Soms kan het zo makkelijk zijn, alleen moet het kwartje ff vallen....


Thanks, now I see it!! a picture says so much more then words....

I did, but with the wrong battery in mind... :D

form HK

only that is a Shepherd, not a Serpent... :sneaky:

is there a actual picture of this brushless Serpent 966-e?

It looks good....however, how was that performs? I have friend recently saw a E-1/8th @ ACO in HK....car is super slow, every turn will fish tail, thought that might be the weight problem....I hope that was not the same one as this Shephard.

Yes there is on the Serpent website.

It seems they have choosen the LRP SPX8 combo set and probebly the 2800kv version. I have calculated the theoretical speed with the rpm, transmission and 76mm tires and it will hit the 100km/h

But with this in mind:
http://www.rctech.net/forum/6609771-post7.html

I'm a bit worried.... :D

i was what the price on this car?400?600?
when is the projected release date?

I second that..:nod:

This one just like the nitro one...I doubt it will be any cheaper then the nitro one.

1st test....

Check it out ... Pics
Still no noise no racing

i love the whinning noise.....i want one now....:D

plus 1 on that nothing beats the nitro sound and rush of it,espially in offroad and onroad its even better

Then you need this..

Guess what happened here in this video...? Try to LISTEN...:eek:

http://www.youtube.com/watch?v=UYxjk...eature=channel

BTW...I can't believe MS would actually test the car on the driveway instead of their own testing track....what is the point? Proved the electric car can move 50 feet?
