I purchased two turnigy t20 3y 730 or 1280 kv brushless motors and two 200 a turnigy sensorless esc's for a project that i am working on. anyways, i have yet to get power to the esc's or motors. my transmitter and receiver are bound to the turnigy 6 channel 2.4 ghz transmitter and my 6-50 v sbec is hooked to my receiver to no avail. is a programming box needed? hobby king says that this setup can be used in default settings? i have two 5s in parallel power one motor on my desk as we speak. all connections are good according to my meter is have power to the esc. any help would be super. thanks in advance

Do you have steering working?
Not sure which model ESC you're using, but does it have a built in BEC? If so, have you de-pinned the red wire on each connector or are you using a Y harness with the single red wire de-pinned? Are you operating these ESC's on separate channels or combining them into a single throttle channel on the transmitter?
Too much could be wrong with a bench-top test scenario. Pictures would really help.Vac-U-Tug Jr (13mph)Comment

I believe this is the ESC purchased.
https://hobbyking.com/en_us/turnigy-...ucts_analytics
This is the manual
The ESC has no BEC so a UBEC is required as referred to by the OP. I cannot help with your issue, however, the T20 is a four-pole motor and the ESC has firmware for a two-pole motor. The Hobbyking blurb states that a firmware upgrade for a four-pole motor is in the files tab but for many years now I have never seen a link to the upgrade on the website. I was initially interested in these however the absence of a firmware upgrade link and the numerous poor reviews raised a red flag to me.
Edit: note: should you get the ESC to function then a programming box is needed as the default setting on the motor timing is "very low", which is more suited to a "D" wind than a "Y" wind motor. The T20 is a "D" wind motor at 1280kv and a "Y" wind motor at 730kv.
Edit #2: read from post #18 onwards in supplied link. I have not watched all the video link but in the first few minutes the person states downloading software upgrades prior use.
Edit #3: The applicable programmer like many Turnigy products seems to be unavailable (out of production?). For further info on the ESC see the last entry in the link
Hi Fabien, Just seen this post. I have the same esc but could not find programming software. Hobbyking sent me to manufacturer of that usb programming hextronic, but software can’t be found anywhere. I would really appreciate if you could send me the software to my gmail. [email protected] Many thanks.Last edited by Old School; 07-27-2021, 06:19 PM.Comment

thanks for getting back to me. I originally bought two motors and two esc's for the purpose of a twin screw boat, but with the physical size and power of these engines
i decided to go single screw. The esc i am using is a turnigy water cooled sensor less esc which has an input voltage of 15-33 cells using NiMH and 6-12 cells lipo.
I am using a y connector and two 5000 mah turnigy 5s batteries for a combined fully charge of 18 to 20 volts. the esc does not have a built in bec, so i have a 6-50 volt external
sbec powering my receiver and regulating voltage manageable for the esc to work. i will send pictures. thxComment

thanks for getting back to me. I purchased an sbec 6-50 volt (told by hobbyking). i can try the Delta configuration at 1280 kv and see what happens? i researched the programming box on edit #3
maybe i can get one. i bought the turnigy usb linker, but cannot fine a way to download the software. my connections are soldered and according to my meter i have power to the esc. thanksComment
