8000w in a baja 5b ????
 

Hi !

Do you guy's think that a baja 5b ss coud handel a 8000w lhenner motor on 10-12s lipo ?

And what esc and motor woud be best fore this car ?
Where can i get some piniongears that works with the bl-motor ocnd the spur in a baja5b ?

My guess is yes... some guys are claiming to have weedwacker Bajas with 7hp so I guess a 10hp electric would be ok.

:)

your probably going to be looking at some custom pinions too. Which lehner motor are you looking at?

be prepared to spend lots of money on batteries....... it should hand the motor fine.. I know the FD guys are using the 3040...

you're going to have a lot of custom work ahead of you my friend... as I am/been working on the 1/5th brushless for a while...

Yes i know !:lol:

But that's the fun part ! to fab motor and battery mounts and so on !
Woud a 12s flightpower 5000mah be enough ? to get like 25min of runtime ?

When Aqwut meant lots of money on batteries, he meant lots. If you want 25min. of solid run time you will need a 12S2P or maybe 3P specially with the kind of power you want to put out. Try a 12S2P set up first and if that's not enough go with 3P, but your weight will be close if not more then 30 pounds.

If you are looking for 8000 watts, you will probably need a bigger pack than that. 8000 watts at 44.4v is 180+ amps. I personally think tht would be pushing the 5000 cells a bit. But tecnically its within the specs of the 40C burst limit. so it should work.


As for run time... Who knows??? There isnt alot of data around yet for runtime on huge, heavy, high voltage setups like that. If I were a betting man I'd say no on the 25 minutes, but thats just a guess.

ok :) But if a setle for 6000w ? then i chouden't need more than 136amps on 12s ? or choud i go fo an 15s setup insted ?then i don't need more than 110Amps.

How mutch woud this setup cost me ? are 3000$ enough ?

Why not go with 20S :lol:. Wait for the SHV and get yourself those 4900-5000mAh 37V packs from TP, FP or KP and go with a Neu 2230/2Y 365Kv or a 2215/3Y 480Kv.

i'm willing to spend like 3000-5000$ on just the bl setup and lipos excluding the hpi baja 5b ss kit ! Will that be enough ?

How about putting a down payment on a tesla instead?

Anything is possible, but I don't think you will do this with only $3K. It sounds like you are going to have to go big and $3K may get you started with batts, and a good motor, but that kind of power is going to kill your truck and show you weak points in your rig that have never seen BL power. Batteries alone will probably run you in the $1K to $2K range for that level of voltage and mah with enough amperage to do the 6000 or 8000 watts:gasp:. Personally I hope you find ways to do it for $2K:party:. This project sure does sound like a lot of fun though. I was thinking about getting an XTM MMT myself and converting it:yes:. So your leading the way for ideas. Thanks for sharing this with all of us. Good luck with that.:yipi:

Tesla
 

You know if you live in like California or similar you cna get a pretty good rebate from the state and even more from the federal gov for purchasing an electric car, which in turn will reduce the total cost of the Tesla at $106K:lol:

I'll be more than happy to take the $5000 and show you what that kind of money can do to a 1/5 scale vehicle :lol:.

Well you could do :

- 20S 3P A123 for $480
- Motor 3080 Lehner $800 (note rated to 50V not 66V but hey CC overvolts well or do 15s 4P)
- ESC Hydra 240HV $450

Custom water coolering - just use a PC water kit and you're done for under $2k

How will the baja 5b ss handle on a track with a 20s and 6000-8000w set-up?
I don't whant to speend like 6000-7000$ on a car that handles like crap if you guy's know what i meen ?:lol:

Well you are going to be the first so let us know...

There is a ex-baja out there but doesn't need/have anything like this...

It might handle ok. Everything will be pretty much centered.

I got a question. Will a 2050 lehner 10T work in a 5B? I was thinking if i ever get one i'd get this esc http://www.rc-monster.com/proddetail...2carcontroller and run 10s lipo's. Would this setup over do the esc? what pitch are the 5B's? and where would you find the gears if the RC Monster ones will not work?

When I get a chance to make a large scale electric, my choices for motor will be the Neu 22XX series. They are easier to get and if they need repair, I can send them to Neu. If the Lehners and Plettenbergs do get more attention (Open a office and service center) and cheaper in the US, then I'll have 3 choices. The Neu 2215/1.5Y 1020Kv should be a perfect motor for 10S and it is right there in price with the Lehner 2280. Mega should make a motor to compete with the big guns, but they still have to be sent to the Czech for repairs.

hehehe ... 8000 Watt and 2 wheel driven. I don't think you will ever be able to put this amount of power to the ground. A lehner 3040 is not needed. Some german guys converted 1:5 touring cars with a Lehner 2250. Wheighing 13.9KG (30.4lbs) they were able to reach 95mph (145km/h). With a 10S/3P 4000 lipo they needed 125-160A while accelerating (around 4.5-5.5KW input). From 0 to 95mph in 4.8 seconds. They used a prototype ESC from BK -> Cool 250/40 250Amp/ 40 cell Nimh.

MGM 12032 Car/Boat should provide up to 5.5KW. I guess this should suffice to outaccelerate any Baja with the hottest modified gas engine. Runtime will be the biggest drawback on an electric version and/or the cost to get a pack with enough mah (>10000mah+).

Wheightwise a Neu 1527 is comparable to a Lehner 2250. With a Neu 22X (Bam) you would be on the safe side.

thats the biggest prob. i dont care how much the buggy weights. your not gonna put that much tq down. It would make a hell of a speed run car. but it would be soo big you would need to drive next to on the freeway:whistle:
you would be better of finding the biggest 1/8 mt and converting that. Or find one of those 1/5 trucks.(but i think most if not all of them are 2wd also)

[QUOTE=dubkatz;168255]I'm trying to get one of those 4WD 5th scale vihicles. I spoke with one factory overseas and they sounded very interested, but haven't heard much from them. If they do send me one, I'll be buying a SHV controller as well to run it with 20S lipos, not because of the power, but to keep the run times close to 20 minutes.

[QUOTE=lutach;168256]I've been looking for a 1/5th scale 4wd truck also....none exist except for Smartech's but they want a 2nd mortage for it. No thanks...

How about a cheaper route than spending thousands....

Turnigy HV esc...$100
KB45XL 700kv....$55
Two Zippy-R 6s 4500mah at $160 each

Total cost $475.00 and plenty of power for a baja 5b.

yeah, you're gonna need voltages in the 80-100v range (21s-27s) to keep current down if you really want 8kw. The question becomes: where are you gonna get such a controller???

Another option would be using two regular HV systems (two of the ones BOOGIE listed) - one on each wheel. You might have a tough time syncing them up, but that can be done via channel mixing.

SHV is as good as you can get. They are coming out with the 250 amp version and 20S capable.

I now know the place that sells the SHV, but I still haven't heard from Patrick if it'll be possible for a simple car software. I called him again today, but forgot he went to China. I know another company will be making a 20S controller as well, but I'll have more info on that in 8-10 weeks.

Yeah, well, it's not out yet - but I'm sure it's "coming soon". :wink:

The SHV110 is out. I thought it was a joke when I saw the site and forgot about it, but when jzemaxx said something about it in the other thread, I knew then it wasn't a joke. I'm just waiting to see if Patrick says OK, for the simple car sotware and I'll get some.

Yeah the SHV is out already in a 110 form and also if you special order they will do it in a 160 amp form as well.

Where is it? Don't see it at the site...

You have to call tech support. They will point you to a company call BVM that has exclusive rights right now on the SHV's.
