Well the verdict is in...and these ESCs are absolutely awesome! Never dealt with XC until now but I guarantee it wont be the last time! Historically I have always ran Castle Creations ESCs when I think of maximizing a setup and they have been solid performers but do carry somewhat of a hefty price point. Don't get me wrong they perform magnificently but not everyone has CC money. That problem is solved thanks to XC, the new kid in town that's making waves across all scales. My first experience came when building a custom rig for a customer that wanted good performance but nothing over the top. He was going to simply take it out on the weekends and run a few packs through it on an array of surfaces, nothing to hardcore like skate parks or construction sites. Electric wise he was after middle of the road so we quoted him a moderate power setup that would land him ideally in the middle of the power band. I ordered 2 ESCs form XC direct via Amazon(I will include a link at the bottom of this thread). The first one we soldered up and installed went into my personal rig(Et48.3 fitted with a 4990 1650Kv Brushless) for field testing and it replaced a Mamba Monster 8S. I set out to run this ESC hard & push it's limits on 4S and eventually 6S. It handled it everything I threw at it without batting a lash, I was expecting a slight drop off in performance moving to the XC C8 from a CC MM8S and quite frankly that drop off never came to fruition! After running a couple full packs through it, the temps were not that high (115F-ish) and the performance remained steady even near the lvc(set at 3.4v per cell). We called it a day and I went home, soldered up the second one and installed in my customer's build with confidence & without hesitation. For the price point, there is nothing...I repeat nothing comparable for the price that comes with Bluetooth OTA programming for under $100 USD! I am heading into 90 days of use in my personal rig with no issues to report whatsoever and I'm still in awe of the engineering to price point value this ESC brings to the table! Below is how we'll rate electrics now and in the future that come across our workbench. Here is the comparison of the pros and cons of investing in a XC C8 ESCs:

Pros:

*Price: Range between $75-$100 USD, may be found cheaper with discounting and promotions.

*Presentation: Comes neatly packaged with 3M double sided tape for mounting, 6.5mm bullets, spare wires & clear, concise instructions.
*Build quality: Black anodized CNC casing with 40mm cooling fan attached, 10AWG wires, push button, covered power switch that's mountable.

*Connectivity: Bluetooth OTA programming built-in that only takes minutes to connect and programs with ease. User will have to solder connector of choice on ESC. We recommend QS8 for maximum performance and to prevent dips in voltage under heavy throttle.

*Fun factor: Extremely high and gratifying when you weigh the cost to feature ratio, easy setup allows you to get right into without all the formality and red tape

Cons:
*6S Lipo limitation but for most that will be suffice.

*Sensorless set up, look to a pro model if you would like a sensored setup.


All in all I can't recommend this ESC more than I already have. It impressed me and I'm sure I'm not the only out there that will take note! It's a PERFECT choice for the budget conscious consumer running anything from 1/12th scale to 1/8th scale that wants fast, reliable fun without complex set up. If anyone purchases one and has questions, feel free to shoot me a message and I would be glad to assist you!

After seeing a YouTube review of XC esc's I thought I fancied trying something new.
I bought an E6 and C8, the pricing on these when I bought them about 3 months ago was insanely cheap.
So far haven't run the E6 but tested it and setup in its new home, the C8 has been run in anger 😂 drive it like you stole type of bashing, all I can say is WOW.!!
I agree with the above, nothing can touch it for price point vs performance and build, if your in the market for a new esc give one a try.. :celebrate:
 
Can I use these escs without a phone or no?
You need a phone for changing settings only, but you wouldn't need your phone whilst out with your car/truck/buggy etc..
I just checked the instruction manual for my E6 and C8 and neither seem to be programable without bluetooth and said bluetooth device phone/iPad/tablet etc

Thanks! 👍
 
I have the C8, only ran it once thus far, but it ran my 4092 powered Mojo 6s easily. I have an iphone, the app is not compatible. I’ll have to dig out an old androind to change the BEC settings I guess.
Throttle range is pretty easy to set, no phone/app needed.

Look up the app ”RTR-Link” if you're running IOS, I found this works without any issues and takes seconds to mate via Bluetooth.
 
You are getting these direct from their site, through amazon, or?
No ali express. But you have to hunt for the ones with the good price. Last one was 80. So 5 bucks more. One before was 77 bucks. Under 85 bucks is a deal. Amd they are on amazon for 115. This is CDN dollars.
