ko propo brushless esc
1 Attachment(s)
hey all: What's the latest info and possible release date for the new ko propo brushless esc? All i could find was this pic,but no info. Thanks :spidey:
|
next season
i was told by a company rep |
Adachi ran it at TITC in feb, and looked good, its a very neat unit.
Though i then saw his car at a euro race only a few weeks later with a Nosram back in the car, so dont know if there are problems, or if he can only run it with the KO reps present. |
Some new info:
http://rctouring.eu/images/kopropo_vfs1_bmc_1.jpg Ko-Propo has released some official information about their first brushless electric speed controller. The VFS-1 BMC was already spotted at the Toy Fair in Germany, but no information about the specifications was given by Ko-Propo. Ko-Propo Japan has says that the new ESC will have an max. rated current of 3120A and a continuous rated current of 780A. The size of the VFS-1 BMC will be 33.4 × 37.0 × 16.8 (mm) and it will weigh 30.8g (without the wires and the fan). It will be able to run on Ni-cd, NI-MH and LI-PO batteries. The VFS-1 BMC will have a motor limit of 4.5T. Ko-Propo will release a 'Words Specification Kit' for this ESC. The kit will contain a fan and a heat sink which will reduce the heat and will give an motor limit of 2.5T. The VFS-1 BMC (No.40050) will come out this summer and will cost around €200 euros (¥31500 Yen). The 'Words Specification Kit' (No.45521) will cost around €15 euros (¥2100 Yen). |
They look good. The only thing that confuses me is the AMP ratings. There in know way the copper traces and wires can handle max. rated current of 3120A and a continuous rated current of 780A. They can't go by what the max. rating of a MOSFET is.
|
The 80's called, they want their style back!
I'm sorry, but those just dont look like electronics that are coming out in 2008. Am I wrong about this? |
I like how they look. I'm pretty sure they'll do something with the heat sink to mach the gold accents.
|
crap, now I have to debate whether I should wait for this or get a speedpassion setup.
|
I think Ko-Propo is going retro, and I like it :batman:. I always preferred the looks of the KO Mars over the Helios.
Greetings Victor PS: @redbones: I've got the SpeedPassion GT and it's great! |
I just got a used VFS-1, their quality is superb. very pleased, will look forward to this one. ;)
|
I heard these things were going to be tiny. 33x34mm is pretty small, but I was expecting smaller. Where does the sensor harness plug in? With the fan and heatsink(Worlds Kit), $334.00.
|
not sensored
...sad face... :( |
Not sensored???? Who is going to buy a $334 sensorless speedo? What kind of motor would you even run with it, Castle? So you're saying Hara was competing with sensorless motors?
|
I don't Hara was running one of these, it was Shin Adachi
|
Shin, thats who I meant. You get the point though,(insert name of professional racer here) was using a sensorless to compete?
|
There are motors out there that will operate in sensored or sensorless mode depending on the mode the controller uses. Aren't sensorless systems more efficient in racing conditions?
|
urmmm. i didnt think sensorless was legal for racing? well.. at least here in Australia anyway.... ??
|
I think sensorless controllers are legal for racing. Look at the Tekin R1/R1Pro. Most people use the sensored to avoid the start up problems some sensoless controllers have with slotted motors. The motor is the one that ROAR seems to have a problem with as they must be Wey wound and I think a few sensorless motors are Delta wound. A sensorless controller will control any kind of brushless motor. I used my MM to run a Novak HV4.5 motor. All you be doing is not connecting the sensor plug. A sensorless controller uses BEMF to sense where the rotor is and a sensored uses hall sensors. The Trinity N80 for example is a similar designed motor as a sensored Novak, but the N80 is sensorless and I used my HW controller with it. Sensorless techology has come a long way. Some sensorless controllers now have amazing start up and can compete in racing I think.
|
maybe it was the motor im thinking of...
|
Scientifically you're probably right. But the perception right now is sensorless=entry level/cheaper products. And being that is that way, they're going to have a tough time selling by far the highest priced ESC out there with the way people look at sensorless.

I'm not disagreeing with you. I was just pointing out that sensorless has lesser performing, lower quality stigma attached to it in touring. I know very well that 1/8 scale is all sensorless, so it obviously works well.

Did you notice at what alarming speed Tekin does update there controller, There is a lot of room for improvement. BTW Xerun startup sensored but does run sensorless once launched.

Before you guys get too fancy, the KO brushless speedo is sensored only and doesn't have sensorless mode. This is what the fellow KO collegue told me in Thailand...

Please fill us in on more info when you get them. Thank you. |
Hey, I'm the LRP and not the KO technician... :D
Sorry, don't have further details that are not already mentioned. |

Yes, I'm aware you are LRP. Could you ask your fellow KO collegue for more info? With the good success of controllers that can use sensored or sensorless, it would be good to know if KO will go that way. I checked all the pictures I have of the KO controller and I couldn't see any sensor port. Could it be under the where the motor/battery wires are located?
No final release date for the ESC but scheduled for later this summer. |

I just returned from Japan today after attending the Shizuoka Hobby show this past weekend. The ESC will only operate with sensored motors. The sensor harness, fan plug, switch lead and lead going to your Rx all come from under the battery & motor terminal post.

I knew that didnt make any sense that this was sensorless.:confused:

So now that we know it's sensored, what unique features does this have to warrant a $300 plus pricetag?
|
luntach- I believe that we will leave the motors to the motor manufactures.
jla8874- Full tuning option of KO's patented VFS (variable frequency system) technology plus other setting. |
Does the speedo come with a gift certificate for the Elephant Bar?:lol::lol::lol::lol:
Que pasa Roberto? |
Thanks for the answer KO Staff. One other question for you though, and its about your "industrial design". Is KO purposely going for a retro look or what? That new EX-1 UR looks more suited to 1988 than 2008.
|
Butter- :ha: Getting ready to leave for the Reedy Race. If you go, I'm sure I know where you'll be. SF? :weird::lol:
jla8874- KO brought back the EX-1 design due to demand. FYI the design has been around longer then 1988. |
personally.. the more retro the better! nothing beats old skool looks and chunky edges with brand spanking new technology under the skin :D
cant wait for the brushless speedie! |
Are you going to be here everyday answering questions KO Staff? If you are, maybe we need to start just a KO thread in general for all KO related questions. Im an Airtronics person myself, but if I come to find that KO is another customer friendly company, you might just win me over. I have been thinking seriously about trying out the Esprit sticks loaded up with some of that KO 2.4 action when it gets here.
