Works great. Don't listen to the comment about drag brake as you can tune it thru the radio. I'm using it on my Losi Nascar paired with a Flysky G7p and it's smooth and very responsive. Great product and the price is even better.
This is the ESC/Receiver found in the Element Enduro Bushido+ and Zuul IFS. For what it is it is very impressive. Great low speed control. Controls hour LEDs. The transmitter that comes with the Elements allows you to adjust drag brake on the fly. Great little 2 in 1 unit!
This is a great idea but executed poorly. You can not program out instant 100% drag brake making this a crawler only esc / rx combo. If you could just turn off the drag brake this would open up a world of opportunity for this thing, especially custom micro projects. If a crawler with 100% instant drag brake in forward and no drag brake in reverse is what you seek, this may be it. Bummed.
Reviewers generally find the R4D receiver and ESC combo responsive and smooth, with good low-speed control and LED control praised, and one reviewer notes the value is strong. The main point of disagreement concerns drag brake: one reviewer says it can be tuned via the radio, including on the fly with the Element transmitter, while another reports that instant 100% drag brake cannot be programmed out, limiting use outside crawlers. Two reviews are from verified owners and one is unverified. Reviews reference use in a Losi Nascar with a Flysky G7p transmitter and in Element Enduro Bushido+ and Zuul IFS models. Overall sample is small.
- + Smooth and responsive control
- + Good low-speed control
- + Controls LEDs
- + Strong value for price
- − Drag brake cannot be fully disabled in one review
- − Limited suitability outside crawlers per one reviewer
