New solder posts are a huge step up from the older model. Not only easier to solder, but more sturdy as well. I think they will see a dramatic reduction of problems previously seen due to bad soldering causing damage to the circuitry.

Tekin RX8 GEN3 1/8 Competition Brushless ESC
Never been a Tekin 1/8 scale guy, they seemed so unreliable when I started e buggy after doing nothing but nitro. The gen 3 reviews at my local track made me break down and try one on my eb48.4 and this thing is perfect. It’s got the off throttle feel that’s so close to a nitro car that I can run back to back heats with this and my NB48.4 and not have to adjust driving style or braking points. Took a bit to get the feel I was looking for but once it was dialed in it’s perfect.

Nothing at all wrong with the other big brand at all, I just couldn’t quiet get the feel I wanted to mimic my other car and make transitions easier, this has it. Perfection.

As usual great quality product.This my second RX8 ESC.Just as good as the Gen2 but with little more muscle and few more updates.Like the new 250 HotWire update.A bit easier to set up your ESC.Can't wait for the HotWire 3.0 Bluetooth as it would be so much easier to set up your ESC's on the go with the phone in your pocket all the time instead of laptops or desktops.Only one question?Why is there a price drop so soon?Are they revising RX8 Gen3 already?Hmmm.....But I am very happy with the ESC and it dos a great job on my 1/8 scale TLR Buggy.Definitely five stars.

Gotta love a "review" by someone who hasn't touched the product, like J.Anderson. Take his **** for what it's worth.

I have this new esc and it is high quality. New solder posts are awesome compared to the slit type of gen2. Upcoming Bluetooth adjustability is also excellent and class leading. Support a real racer's company by picking one of these up.

Worked great for a while then it started to fail (truck would just stop). Sent it in for service. They said it needed replacing and wanted my CC number. I won't buy another. Many of my buddies at the track had the same experience.

Tekin RX8 GEN3 1/8 Competition Brushless ESC
For the person who wrote about the switch, when has a switch been good on an ESC? Cut it off, solder the wires together, and don't worry about it.
Anyways, mine is great. First one failed after two months. E-mailed Tekin. Within 24 hours had a RMA and they replaced. I've always owned tekin. This is the second ESC that has failed out of quite a few. But they always stand by their products and for me that makes all the difference as these cars get abused especially when racing in 96 degree weather of Florida.

Tekin RX8 GEN3 1/8 Competition Brushless ESC
The tekins gen3, is pretty smooth much better then the gen2.but the hobbywing xr8 is smoother and more durable then. The gen.3,tekin needs to beef up the case on these esc, s compared. To the xr8 its terrible in durability. But its above average thow .

Tekin RX8 GEN3 1/8 Competition Brushless ESC
This speed controller is about average. When I got it, the soldering job was easy compared to the older version. The switch is so flimsy that my car has turned off on it own twice during an a main race. Great way to lose a full minute and half and fall in last place. Been developing a lot of glitching lately. A couple time I turned it on and nothing is working and the lights are blinking (wrong motor type)?? It is the motor that came with it? I am going to try hobbywing and see if theirs is any better.

It's unlikely that these are any more hardy and durable than the gen2 ,the switch is still the same old fragile rubish ,good for indoors .
