  • Castle B link
If you have a Castle ESC you may want to get this. This plugs directly into the ESC and allows you to communicate with your rig via Bluetooth, on the go.

  • Works Great
You will need to know the stock password once the Bluetooth is connected to your phone in the castle app. It is 1234 and then you can change it to whatever you want nowhere in the packaging. Does it say the passcode?

  • DO NOT BUY THIS.(Note you have been warned).
I liked the review from the guy who did the video of his esc just beeping, it was funny and I laughed. I am not laughing anymore, my esc did the same thing. I should have read the reviews first, but nope. Figured it was a Castle what could go wrong. Purchase two, one worked and the other was a nightmare. Some times it kinda worked. When it worked it would change my settings with no way to change it back. It would crash in the middle of updating the esc, the last time it bricked it.way too many problems to list here. Call Castle tech support and they said don’t use these, use USB instead. $80 wasted. ... show more

  • It will change your life!
Unfortunately mine got lost in the mail but I went to hobby shop to buy mine, for a while every time I needed to change a setting I had to take the esc off, and after doing that 100 times I knew this Blink was the best way to go, once you get the Bluetooth linked you can change settings on the fly. One of my best purchases so far for my Xmaxx. ... show more
