ESC Link

This is NOT an official Castle App, you fools need to read. This app predates Castle's very own Bluetooth software by 2 years, I'm sure this app inspired that. Castle still hasn't released thier offical app for Android that will work with their new B-Link yet. It's only available on iOS as of this posting. This app works flawless on older devices/esc but unfortunately, support has ended for this app. App won't work well, if at all, with newer esc's like the Mamba X. New Mamba X esc software has many new features that this app software simply hasn't been updated for. I'd pay for an up to date version of this app. This app was way ahead of what anyone was doing at the time.

bought new field link card, as soon as I opened it I hooked it up to a PC and said it needed updated so I did that and just finally got around to trying it on my Samsung galaxy note 9 with brand new sidewinder 4 and it says that theres a error and thr screen on my just keeps flashing. pretty disappointing.. my buddy showed me this so I bought the bew castle sidewinder 4 esc with the 2400kv motor for slash then bought the bew field link card, updated it and no go... that's total bs!!

Works perfectly for me I have a castle link but no Bluetooth link. This adds allot of portability since I only need my phone to tune.

Seem to work on the SCT version of the ESC. Does not work with Sidewinder 4. Just flashes the screen can't make out what it says.

Doesn't work with the sidewinder 4 on a s9+ kinda disappointing seeing as i basically wasted money on a cable that I now have no use for!

Worked great for some time then did an up date. Tried it on many different phone with no luck. How can I fix this???

I've been using this app for almost 3yrs now and no problems with sw3/sct and MM2 ESC's on my galaxy 6/8/9 and galaxy tab

Not impressed, can't even program a Castle BEC... But hey, that's why I use Tekin for my ESC's... baaaaaahahaha

great. use the otg adapter that come with the Samsung

Doesn't work with Samsung s10+ and sidewinder 4

Works great with my Samsung Galaxy s5 and my Castle Sidewinder SCT!!!

Awesome app, castle only advertised for pc and ios

Works perfectly. With my Savage SX Flux Esc. Excellent job 👌👍

Works great with mamba micro pro and S9

It worked on my spare Phoenix 10 using my Samsung S7 Edge. I made changes but couldn't figure out how to update the ESC's firmware.

Works great on Samsung S8 plus with needed connections and Castle 8. Would like to see it work with Hobby wing as well. Not tested yet

App worked great for me on my S8. Only wish it would be able to program my Castle BEC. I still have to go to the LHS to have that done. Worked for my holmes hobbies esc and my Losi mxpro esc.

Does not work on my Galaxy Note 8. App glitches and screen flashes when connected via OTG cable.

App is great for my sw3. But glitches like crazy when connected with same link and mamba x

App works well with my older sidewinder 3, can change many of the settings that I can in the PC version. When trying to connect to my newer Mamba X the screen flashes repeatedly during the connect phase and fails to connect.

Tested on an Lg G3 with a Sidewinder 8th and it works great. All adjustments went in and worked right. To set the changes you made press the large "check mark" on the upper right corner.

Doesn't work. Screen just flashes when you plug in ESC

It's not bad. It works with my Axial AE2, and Holmes BR Mini, but it doesn't seem to work with my 10A ccBEC.

Does not work with Pixel 2 and Castle Link 3 - screen just flashes. Pretty disappointing. Fingers crossed for a compatibility update, because this would be a really useful app!

App works great on my Galaxy Note 8!! Does not work on new mamba X esc.. needs to have a firmware update to fix this... programs all others I have tried with zero issues and programs by BECs also!

Still does not work on my Samsung galaxy S8. Screen just flashes

This app will not work with castle link v3

Doesnt work on note 4 screen just flashes
