It says UBEC but in the pic it shows SBEC, which is it? I need a UBEC and I really want to place my order as it takes awhile to get here from Hong Kong and I dont think the USA wearhouse has this one

Is it can be comply with boat remote control ?
 e_lm_70 426 points
This is an aeroplane ESC, so you will not get the reverse, that is needed on a boat ESC
 tayothin 89 points
Yes,Thanks however forward only Is oK. Could you kindly trial ?

Hi I'm using plane esc in my cat apparition with alloy cooling jacket installed and all is working perfectly good try it u will love it imo Cheers

I'm back to trying to get the ESC programmed. When I first powered up, it went through all the settings, but I wasn't ready to program yet! (computer locked up and I couldn't scroll down the manual) So, I let it go all the way through and then powered down. I powered back up and now, with the throttle at full I get a beep, beep, beep, then a quicker short sequence of three different notes. It never goes in to program mode. If I power up with the throttle at zero, I just get a continuous beep, beep, beep, etc. until I move the throttle to full. Then I get the previous listed beeps and silence. Anyone have any ideas?

I dident porgram mine it just worked
 nikwal 64 points
1. powered up in wrong order? 2. Not enough maximum stick movement, try trim up max gas..
 chopper50 260 points
Hi, try reset of throttle parimeter, plug esc in with transmitter at full throttle then lower throttle at lowest point this should rest throttle you should get a different beep. hope this fixes it for ya
 Kent 1 points
Thanks guys. Somehow I managed to get it programmed but now I have another problem! I power everything up and can't get the motors to run. BUT as soon as I shut off the transmitter both motors start up at full power! Mind you, the transmitter is OFF! Any ideas on that?
Kent  1 points - 5/24/2012
 
Can anyone understand the manual for this? I'm new to all of this and need instructions in plain English. LOL I can't get anything but beeps from the ESC. No motor function at all. I've made sure the throttle is all the way down, solder joints are good, trims are correct. Still, no joy.
 Kent 1 points
I figured it out, or stumbled across the answer through trial and error. The instructions are less than clear and leave a lot of room for improvement. Once I got the motor up and running, on the bench, I let it keep running at full throttle. Didn't take long for it to get really hot. Probably not the best decision on my part, but I was so excited to finally get it going that I didn't want to shut it down! LOL Hopefully, it'll run just fine after it cools off.

does anyone know what the green circle is that the wire is wrapped up around, and i want to get rid of it but scissors arent cutting it...lol. i figured id ask what its for before i take drastic measures
 Crampy 184 points
It's a ferrite ring to stop electic noise created by the ESC getting to the Rx and interferring with it. Don't get rid of it, it's a good thing to have.

What is the length and awg gauge of the input and output wires?
 crash master 66 points
i don't know abut the length but from the picture the input gauge seems to be 12 and output is 14 hope this helps :)

Would anyone recommend this over the turnigy 85A esc as far quality is concerned? I know some have had problems with the turnigy esc whereas no one has reviewed this one yet, so kind of hard to choose...
 Papabear1956 2 points
I have use this on my Cherokee. It works great. The only thing you have to know is that you can't make any changes using a programming card. The programming cards only work up to 80A. Download the manual in the files area and it will tell you how to adjust factory settings. Good flying

For some reason my question disappeared. http://www.hobbyking.com/hobbyking/store/images/em_r
olleyes.gif Issue
was I could not get the motor to stop running when I took my finger off the trigger on a wheel transmitter. Got help over on the HK forum. Unfortunately the ESC manual did not include this: if you look on page 6 of the manual.the first beep seqence 4 A" beeps is for the trottle. steps to set up 1, hold trigger all the way back (full fwd) 2, power on the ESC 3, the esc will beep(4 times) 4, during this 4(A") beeps release the trigger 5, the ESC will beep 2 times 6,remove power from ESC 7,put power on ESC push trigger foward(full rev sig) 8, esc will count batterys and arm 9, release trigger motor will remain stoped till trigger is pulled in FWD direction motor will stop when trigger goes to mid position
 rcozstyle 315 points
Maybe because it is designed to be used on cars, I think you will find it's meant for planes, I would say it auto detects full travel of your wheel radio so when you release the trigger the esc app us power like it is meant to do.
 KaosKane 1430 points
Rcoz is correct *} ur 0% throttle is to a plane esc 25%

ChristianP  127 points - 8/18/2011
 
Has anyone here used it, I can not find any reviews on it? Is it recommendable? Does it come with all the necessary wires and plugs?
 __remi 10 points
Works perfectly well.No plugs or sockets every has their favorites.

Am I correct in asuming this speed controler comes without a switch to turn off the power to the Rx with and that it lacks auto cut off when signal from Tx is lost?
 Mainframe Data AS 2 points
ESC's normally sies not have switches. HK King 90A ESC is programmable with protection mode. That means that you may use function to either reduce power, or cut off power to your motor. Keep'em flying ****heliviking.no John

How i program this ESC?
 ilektron 66 points
The user manual under files the 'files' tab has instructions at the end. All you have to do is hole the throttle channel fully on when the esc is powered up to initiate programming mode.
 allais 483 points
how to find the instructions of the controller thank you[
Sujit Hait  36 points - 6/19/2011
 
Can i set up this in 'Dassault Alpha Fighter 90mm Ducted Fan EPO Plug-n-Fly'
 ilektron 66 points
Depends on your motor and batteries. On first look, the plane you mention calls for an 80A ESC, 6S Battery, so on paper you should be fine.

What's mean Sensorless Brushless motor?
 ilektron 66 points
Most if not almost all plane brushless motors are sensorless. Starting up a brushless motor, most ESCs guess and use back EMF to determine if they guessed correctly on the orientation of the motor. Planes are fine w/o sensors because the motor is always spinning. Some RC cars have sensors on the motors so they can start up smoothly instead of having to guess.

thank you

Anyone use this on a HK 500 Heli yet? I am tryin to find one that will work pretty good before I order the 500.
Thanks
 dadupi 1 points
I am using on HK500 with default settings, will program soon to allow soft start, otherwise no problems
RealGambler  54 points - 6/13/2011
 
Great price. Is it programmable via on of your card?
 Sawdust 1605 points
Have a look above in the Combo Deal section.
 ilektron 66 points
The user manual states that you can use the 'programming panel'
