In my opinion, there are much higher quality setups that can be had at a lower price overall.
for that price id rather have a couple castle esc/motor combos.
even a couple vxl motors and sidewinder escs if you dont want 4600kv+.
nitrorcx right now is having a sale on some items, I just picked up a tacon brushless 4300kv motor for $22.90 and got free shipping
How about this setup would this be good?
That would be ok, but I'd probably go with the b4 combo since you can always dial down the power if it's too much.
Would a 6000kv still do wheeleis and will it do damage. Also do i need 2 batteries
wheelie's on command- no damage
I run my setup on a single 2s lipo just fine
so Budhatrain you have the 6000kv combo?
Does there have to be pnlinion changes or annything?
I do... glad I did too. Out of the 4 setups I have it's the fastest- I have 2 clods with 4600kv castle creations and 1 clod with 3800kv castles.
I use a stock 13T gearing and motors stay nice - just a tiny bit warm but nothing to sweat over. If I was worried about heat (which I am not) fans wor fins could solve the problem easy. Robinson Racing pinions of course.
I got the 6000kv ezrun combo and put one on the rear after about a minute it stopped and smoke came from the esc. The esc was EXTREMELY! Hot. The esc now does nothing no lights no beep nothing. Anny ideas? Is this a Fault?
Fault of the owner
6000kv is to much and will cause extreme heat.
ESC, was it at least a 60 amp model or did you install a lesser model?
I have the 60 amp esc. The thing is Budhatrain said he used 6000kv and on the website i bought these 6000kv setups from said they were for offroad. This is confusing because i thought lower kv more torque but on nitrorcx the lower kv setups are only for on road use.
generally speaking, the lower the kv the higher the torque...
you sure you werent thinking of a lower turn? generally speaking, the lower the turns, the lower the torque; and the higher the turns, the higher the torque....so a 3.5t motor better suited for on road and a 17t motor better suited for off road...
other factors come into play also, but that's pretty much the jist of it...AFAIK, anyway...
Wiring Harness ?
Okay, never had the electronics thing down. I've two Hobby King brushless esc/motor combos:
Will be starting with a single 2s to run on my cpe terminator. I will y-harness the esc's to the receiver.
What type of harness to connect the dual esc's to the single battery ? Parallel ??
Can someone post a photo ? I'll be using traxxas plugs ? Not sur ehow this gets soldered together ??
Your help is appreciated.
Geez, I'll even paypal someone to send me one I think !
this is the deans plug I picked up: http://www3.towerhobbies.com/cgi-bin/wti0001p?&W=001808213&I=LXPTT6&P=K
so I am assuming that this plug will not work but should give you an idea on how to wire it: http://www3.towerhobbies.com/cgi-bin/wti0001p?&I=LXXKM9&P=ML
so go with one male plug and two female plugs. hope that helps and good luck... I am sure somewhere out there someone has made this and is selling. If not let me know and I will make one up for you.
Thanks for the reply, I hooked up one of the hobby king esc/motors set it up, plugged it into a battery and POOF , the esc/capacitor/motor went up in smoke ! I'm afraid to set up the other now . . . . . .
Perhaps I should have gone with a castle setup ? !
you using a lipo battery?
Yep, a maxamps. It survived though !
More brushless clod questions
Ok even though ive read this entire thread i still have some questions.
The Castle SV2/SV3 5700 system that seems to be the go to system. If i was to use a SV2/SV3 5700 system in my 2wd Slash even with a two cell it would be pretty damn fast and on 3 cell it would kill the 55 mph claim top speed of Traxxas's Velenion system unless those Traxxas motors are ungodly torque beasts in comparison. Is it more useable in Clods cause we are running two systems off one battery (usually) so in effect splitting the volts to 4.2 for a 2 cell lipo or 6.3 for a 3 cell lipo per esc/motor system?
Why are uncensored systems the preffered choice? I thought censored motors give better torque and are much less prone to cogging and better performance overall. The censored esc's are a bit more in price but the motors are real close in price. Ive never had a uncensored system so ive never felt cogging ive just read about it. Is it that bad? I do know censor wires can be a pain and problematic but that is usually from when the wires go bad at the plugs.
Looking at some Hobbyking stuff and its cheap. 60 to 120 amp esc's for 28 to 55 bucks. Have to except that customer service will be next to nothing so if you get bad stuff your gonna be stuck with it for awhile if not permanently. Turnigy has one style of motor that looks so much like a Reedy and i read on another forum they are such a dead knockoff that you can even use Reedy replacement parts in them and they are about 35 bucks shipped to your door. I was thinking about trying out some 3950 kv 10.5's of those. They also have a 5400 kv 6.5 but that just seems so much motor to me. Basically it looks like you can do a 60 amp system for as cheap as 50 bucks.
Im not bashing any manufacturer cause there definately is something to be said about great customer service and backing up the product they sell like Castle does.
1. in a clod, you run the esc's in parallel to the battery, so each esc sees 7.4v...you dont run them in series to split the voltage...that's why a battery with a high "C" rating is needed, since the amp draws from both escs can tax a weaker battery...
2. as for castle being the "go to" system, it's cause it's a familiar brand name system, which is reasonably priced...as for unsensored being "the choice" i think it has more to do with price point...sensored motors dont necessarily have more torque to prevent cogging...it uses the sensors to realize the position of the motors rotor, allowing much smoother throttle, especially at lower speeds and off the line...some cogging issues can be bad, and others very minor...i've had both, and when it's bad, it's very annoying...
knock off motors and escs are great if they work and it's a good price...even the name-brand stuff has issues too though, so dont think you're safe from defects if you have name brand stuff...
