I purchased the Axial SCX24 JLU and while it was fun, I found the stock servo to be somewhat lacking in power while on an incline. So, I looked around and came across these as a suggested replacement. Yes and no. Yes in that these are prob the only ones within the stock chassis dimensions and no because it's still slightly larger. The width (AS-1 vs ES08M) is 21.3mm vs 23.6mm (give or take). Off the bat you know you'll need to mod the stock servo tray. Either fidget with it a bit or buy a replacement that will fit the ES08M. You'll be better served if you trimmed the servo screw mounts a bit so it'll fit neater within the chassis. On my SCX24 JLU, it was just BARELY in between and would rub or hang when flexing. The wire comes straight down on these vs the AS-1 where it comes out directly at the sides. The cable is pretty damn long at about 250mm compared to the AS-1 at 58mm. That's pretty damn long for a tiny servo. Did I mention it was taller? So instead of the steering rod links being parallel with the front bumper, it'll stick out about 2mm. Not an issue but in case you're tight for space. So that's the jist for fitment. It's noisy but has some power. Obviously since it is a bit stronger it'll make a little more noise. Now, noise is subjective so keep that in mind but I did notice these were noisier than the AS-1. All in all, these are about the only ones you can buy to replace the stock AS-1 servo if you need something stronger. If you do find a smaller one that's just as strong if not stronger, reply and let us all know.
Love this servo as a great upgrade for my SCX24! It is a lot more powerful than the stock steering servo, and with some longer screws, can easily use the stock servo tray. With a little extra weight and more grippy tires, the stock servo was significantly underpowered and this upgrade turned my SCX24 back into a fun, crawling beast.
Best bang for the buck! using them n a DLG glider!
This thing walks all over the stock servo, gets the job done and adds a little more weight up front. Be prepaired to modify the stock tray of grab the HotRacing mount. Small downside...the wire is fairly long
Work great, a little noisy though. Plenty of power over stock on a scx24 and even has more power than the ecopower 827 x24 regardless of what the specs say.
Reviewers largely report the EMAX ES08MAII 12g servo is a clear step up in power over stock servos, mainly in SCX24 crawler builds, with several also noting it is a good value. The main recurring issue is fit: it is slightly larger than the stock AS-1 and often needs servo tray modification, longer screws, or a third-party mount, and the supplied hardware and horn are described as flimsy or too small for direct fit. Reviewers also mention a long wire, some noise, and a fit issue with a Deadbolt chassis. One reviewer reports a servo failure after about ten months in a helicopter application, and another reports an ESC burnout when paired with a higher-voltage setup, though these are isolated.
- + Much more power than stock servo
- + Good value for the price
- + Lightweight
- + Easy to install with modification
- − Slightly larger than stock, needs tray modification
- − Supplied hardware and horn are flimsy
- − Wire is fairly long
- − Isolated reports of failure and ESC damage
