This application has convinced me to try and avoid Castle products. So utterly frustrating to use when you just want to make a few simple changes -- Blakersen , 2025-05-08 ### *---- "GARBAGE" This app is junk just like the b link. App crashes and freezes and will brick your esc. Research it and see for yourself. Don’t waste your money on the garbage. -- rls4979, 2025-05-03 ### *---- "No good" Throttle curve doesn’t let u put to curve and when it does it won’t clear or respond -- Nick cyn, 2025-04-19 ### *---- "Zero confidence in Castle Creations" The app stinks. Locks up or crashes. Has problems making or retaining blue tooth connections for any length of time. Failed me again… I gave up on all Castle Creations products…. -- Helium04, 2025-03-08 ### *---- "Bricked my esc" It was working good and all then it just bricked my esc I would not recommend buying the b link totally not worth 50 bucks just buy the usb adapter to tune ur stuff -- Thomas pester, 2025-01-05 ### *---- "Bricked my Mamba X ESC" Attempted to update my Mamba X ESC via Castle B-Link and this app and bricked my ESC. My ESC is no longer functional and only displays a blinking red LED. Do not attempt to update your ESC via this app. -- Bricked ESC, 2024-10-18 ### ***** "Works well, I use it for racing!" I use the Castle B-link frequently for racing 1/8th scale buggy and truggy. I’ve never had any big problems that a power cycle didn’t clear. The data logging is fantastic compared to other manufacturers. -- J.L.Buck, 2024-07-10 ### *---- "Castle creations products are all garbage garbage garbage ⚡️" Horrible products bugs in all the firmware everything from castle creations burns up up up CRAPPY CREATIONS😂😂😂😂 -- Electricity boom, 2024-06-29 ### ***-- "Lots of settings but very glitchy" Trying to use throttle curve settings on iPhone is really bad. Lots of settings. I especially like save profile : I can easily put car in crawler, speed/trail, or a full on burnout mode. -- Rzr n, 2024-02-10 ### *---- "B-Link" Sending this back. Nothing works. You guys should take some notes from Traxxas and the Bluetooth they have. So easy to use even gives mph, tachometer etc. You guys should be embarrassed to even sell this product. -- steelheadslayer, 2023-10-02 [View all Castle Link reviews and detailed analytics on AppTail](https://app.apptail.io/signup?utm_campaign=ai-crawl&utm_content=reviews) ## Apps Similar to Castle Link - [R1WURKS](https://apptail.io/app/r1wurks-ZPq/united-states) - [HW Link V2](https://apptail.io/app/hw-link-v2-Mhx/united-states) - [RC Gears](https://apptail.io/app/rc-gears-OHW/united-states) - [ISD Link](https://apptail.io/app/isd-link-XYVb/united-states) - [RC Setup App by So Dialed](https://apptail.io/app/rc-setup-app-by-so-dialed-TGpc/united-states) - [RC Pit Calc Pro](https://apptail.io/app/rc-pit-calc-pro-wpMc/united-states) - [FuriCar](https://apptail.io/app/furicar-EpMc/united-states) - [RC AI Mechanic](https://apptail.io/app/rc-ai-mechanic-GpMc/united-states) - [ISD Go](https://apptail.io/app/isd-go-LpMc/united-states) - [RC Speed Calculator Pro](https://apptail.io/app/rc-speed-calculator-pro-cAOk/united-states) ## Castle Link Available In - [United States](https://apptail.io/app/castle-link-Wzl/united-states) - [Germany](https://apptail.io/app/castle-link-Wzl/germany) - [Italy](https://apptail.io/app/castle-link-Wzl/italy) - [China](https://apptail.io/app/castle-link-Wzl/china) - [Taiwan](https://apptail.io/app/castle-link-Wzl/taiwan) - [Netherlands](https://apptail.io/app/castle-link-Wzl/netherlands) - [Canada](https://apptail.io/app/castle-link-Wzl/canada) - [United Arab Emirates](https://apptail.io/app/castle-link-Wzl/united-arab-emirates) - [Switzerland](https://apptail.io/app/castle-link-Wzl/switzerland) - [Chile](https://apptail.io/app/castle-link-Wzl/chile) - [Colombia](https://apptail.io/app/castle-link-Wzl/colombia) - [Czechia](https://apptail.io/app/castle-link-Wzl/czechia) - [Denmark](https://apptail.io/app/castle-link-Wzl/denmark) - [Dominican Republic](https://apptail.io/app/castle-link-Wzl/dominican-republic) - [Algeria](https://apptail.io/app/castle-link-Wzl/algeria) - [Ecuador](https://apptail.io/app/castle-link-Wzl/ecuador) - [Egypt](https://apptail.io/app/castle-link-Wzl/egypt) - [Spain](https://apptail.io/app/castle-link-Wzl/spain) - [Finland](https://apptail.io/app/castle-link-Wzl/finland) - [France](https://apptail.io/app/castle-link-Wzl/france) - [United Kingdom](https://apptail.io/app/castle-link-Wzl/united-kingdom) - [Greece](https://apptail.io/app/castle-link-Wzl/greece) - [Hong Kong SAR China](https://apptail.io/app/castle-link-Wzl/hong-kong) - [Hungary](https://apptail.io/app/castle-link-Wzl/hungary) - [Ireland](https://apptail.io/app/castle-link-Wzl/ireland) - [Israel](https://apptail.io/app/castle-link-Wzl/israel) - [India](https://apptail.io/app/castle-link-Wzl/india) - [Japan](https://apptail.io/app/castle-link-Wzl/japan) - [South Korea](https://apptail.io/app/castle-link-Wzl/south-korea) - [Kuwait](https://apptail.io/app/castle-link-Wzl/kuwait) - [Kazakhstan](https://apptail.io/app/castle-link-Wzl/kazakhstan) - [Lebanon](https://apptail.io/app/castle-link-Wzl/lebanon) - [Mexico](https://apptail.io/app/castle-link-Wzl/mexico) - [Malaysia](https://apptail.io/app/castle-link-Wzl/malaysia) - [Nigeria](https://apptail.io/app/castle-link-Wzl/nigeria) - [Norway](https://apptail.io/app/castle-link-Wzl/norway) - [New Zealand](https://apptail.io/app/castle-link-Wzl/new-zealand) - [Peru](https://apptail.io/app/castle-link-Wzl/peru) - [Philippines](https://apptail.io/app/castle-link-Wzl/philippines) - [Pakistan](https://apptail.io/app/castle-link-Wzl/pakistan) - [Poland](https://apptail.io/app/castle-link-Wzl/poland) - [Portugal](https://apptail.io/app/castle-link-Wzl/portugal) - [Romania](https://apptail.io/app/castle-link-Wzl/romania) - [Russia](https://apptail.io/app/castle-link-Wzl/russia) - [Saudi Arabia](https://apptail.io/app/castle-link-Wzl/saudi-arabia) - [Sweden](https://apptail.io/app/castle-link-Wzl/sweden) - [Singapore](https://apptail.io/app/castle-link-Wzl/singapore) - [Thailand](https://apptail.io/app/castle-link-Wzl/thailand) - [Türkiye](https://apptail.io/app/castle-link-Wzl/turkey) - [Uzbekistan](https://apptail.io/app/castle-link-Wzl/uzbekistan) - [Vietnam](https://apptail.io/app/castle-link-Wzl/vietnam) - [South Africa](https://apptail.io/app/castle-link-Wzl/south-africa) - [Argentina](https://apptail.io/app/castle-link-Wzl/argentina) - [Austria](https://apptail.io/app/castle-link-Wzl/austria) - [Australia](https://apptail.io/app/castle-link-Wzl/australia) - [Azerbaijan](https://apptail.io/app/castle-link-Wzl/azerbaijan) - [Belgium](https://apptail.io/app/castle-link-Wzl/belgium) - [Brunei](https://apptail.io/app/castle-link-Wzl/brunei) - [Belarus](https://apptail.io/app/castle-link-Wzl/belarus) --- ## About AppTail [AppTail](https://apptail.io) is a mobile app intelligence platform providing app analytics, ASO (App Store Optimization) tools, keyword tracking, competitor analysis, revenue estimates, and review monitoring for iOS App Store apps.
