Shark speed controllers

Hi Graham, (and Geoff sorry) that F/S usually applies only after you have set all the parameters, mainly an aeroplane thing to stop you amputating your fingers (or unintended take-offs)😀 Not such a danger in boats. A number of this type will also chop the throttle if you loose signal. Most seem to use an Atmega chip and have similar setting menus. I have around 30 of this type (varying Amps) for planes, and they are all pretty much the same. No problem using the ESCs BECs when setting so far.

You usually have to start setting these types of ESCs with throttle at full, then back to center (for forward and rev) or bottom for fwd only, (if they are a F/R type) then unplug power, then TX on, full throttle, power on then set choices (beep numbers) in the first menu by throttle back quickly to center or bottom (whatever was initially set), back to top after confirm beep, next menu section opens and you repeat for each item you want to change.

Both menus keep cycling when you are in them, so if you miss what you want, it will come round again, ( helps to have an enlarged copy of the instructions handy and follow it as you go). when you have everything you want set and confirmed, unplug the power. Now when you want to start normally, put the stick to the center (or bottom if initially set there) turn on TX, plug in power and you should be good to go.

I look at these menus like a tree,- sort of trunk, branches and leaves, - 1 -up the trunk, 2-out on the branch, 3 - into the leaves and away. Everyone sees things a different way, so you have to find a thought process that clicks with you.

They are simple but time consuming, a program card is a lot quicker😁

Thanks Graham, have tried this to no avail, have sent the following diagnosis to the retailer today.

Diagnostic Steps taken today 30th January 2021

Power setup -Flysky receiver, with shark esc and Thumper motor.
6 Nimh cells reading 7.67V

1. Another motor AXI 282010 connected to esc. Servos run ok motor does not beep.
2. Thumper motor runs with another controller.
3. Another controller and motor respond to Tx.
4. A servo works in the motor channel (3)
5. The esc in the battery socket powers the other servos.
6. The ESC in Channel 3 powers other servos.
7. The esc in Channel 3 does not respond to Tx command nor emit beeps.
8. Throttle channel revers switch makes no difference.
9. Output from BEC reads 4.99V
10. A separate battery pack in battery channel does not let the ESC start programming.
11. Tried different receiver.
I have duplicate setups, that is Shark ESC to Thumper motor, neither shows any response other than those above.

Geoff,

Reading through the instructions, to get into programming mode, it suggests you set the transmitter throttle to maximum, and then connect power to the ESC. The problem may be occurring because you are using the BEC in the ESC to power the receiver. I think you may need both the Tx and the Rx powered, before you apply power to the ESC to get it into program mode. That means you will need to power the Rx from a separate source. Once it is programmed and working, you should be able to revert to using the BEC

Graham, Thank you for your various replies and the pdf of instructions, will print them off and work through them, but what really is the problem is that I cannot get past the first described step, because it does not respond as expected from the instructions. I have bought two identical set ups, motor and controller, for a new project and neither responds, have tried two receivers with no result. Will continue to consider the problem and try different settings, meanwhile await reply from retailer.

Thanks Colin, It does have battery selection, and is set to Lipo by default and I am using Nimh, but I can't get into the programming function, because the first step does not occur. Thanks for your nice comments on my last build, but I do have another kit waiting in the wings, an HAKIts Pilot Launch

Hi Graham 93,
I think you might have unlocked the problem with instructions. I had a problem with my Hobbywing 1060 Brushed Controller. It took a couple of goes but then worked fine! Most SC's even for marine use have a failsafe built in, the problem being getting it to learn

Just found this using Google:

“includes a high-throttle safety function that prevents the ESC from arming the motor if the throttle stick is not fully closed”

Looks like you need the Tx throttle set to minimum before powering up the Rx and speed controller.

I used three in my Brave Borderer and all work fine. They replaced the original Hobbyking, which did not.
The first required programming as it was set Fwd only. Did that by the "beeps" technique, which is much harder than it seems!
Think there is a now programming card available, but have not used it.
The next two came set for Fwds & Rev., so did not have a reason for programming. Left them well alone!
Got mine through BANGOOD a while ago and there might be instructions on the web.
Your wiring looks correct and, as the BEC circuit is working, that feature looks OK.
Forgotten how to get into the programming mode, but that might be your next step.

Just a thought, does it have jumpers or switches for battery type selection.

Hi Geoff,
I have not used brushless motors and there speed controllers before.
So you have voltage in on the red and black wires but nothing on the output.

The receiver port is working as you have tried a servo in it.

The receiver is bound to the transmitter.

Unfortunately it is looking like you may have to replace the speed controller.

Maybe another member might be able to help.

If it looks right it probably is.

Thanks Martin, the Red light turns from blinking to solid when the Tx/Rx are bound.

Hi Geoff,
I see you have a red light in your receiver.
Is your receiver paired with your transmitter ?

Thanks Martin, I have tried a servo in the Motor channel and this works well, Voltage in, with servos under load is 7.67 V.
As the motor is not running then a v out is not measurable and of course is in ac anyway. I have spoken to the retailer today and sent them a pic, they did not have any immediate solutions. There are instructions but it does not respond to what is stated.
Thanks Geoff

Hi Geoff,
I am assuming it came without any instructions.

Dose it have a reset button or a hole that you have to put a pin in to reset it ?

Do you have anything you could use to confirm voltage in/out (multimeter) ?

Maybe you could post a photo of it then we can see what we are talking about.

Just check the radio Plug a servo in the ESC slot and see what it does

THanks for suggestion Ian but does not seem to make any difference, have e mailed the retailer today, the chinese are not particularly good with supplyig instructions1

Sounds like it has a failsafe, make sure throttle is in Neutral before switching on. A lot of these controllers are used by the aircraft boys. ZTA China make these and they have adjustable end points

Shark speed controllers

Has anyone had any experiences, good or bad with Shark speed controllers for brushless motor. I have recently purchased one with a Overlander thumper V3 and nothing happens at all, no beeps nor nothing! It powers up the Rx and drives the servos but no response on motor channel, have tried servo reverse switch
