1/10 Scale EXI Digital MG D226F Servo Review
Article by Hunter Wick
Buuuuzzzzzzzz. buuuzzzz. Don't worry, there isn't a bee hovering in your ear, but rather one noisy servo. This is what this servo from HobbyPartz.com sounds like almost constantly. While this can be annoying when sitting on the workbench, it isn't even audible when driving your RC vehicle around. For this reason and the fact that this servo cost under $15, I became quite fond of this servo, and these are my thoughts on it.
For those who are new to the hobby (it's OK, everyone is new at some point or another) I am going to go ahead and take the time to explain what a servo is. A servo is an electric motor with a small electronic board in it. This board acts as the electronic brain, interpreting the information sent to it from the receiver. Sometimes servos are used to pull the throttle on a nitro or gas engine, but most often is used to steer the car. There are many different types of servos, ranging in price from $10 to $300 and up. If unsure about your servo or which one to buy then be sure to consult an experienced hobbyist for assistance.
Packing and Shipping - 9/10
This servo came shipped without damage, so overall I was happy. There is one thing I would like to see HobbyPartz improve on the shipping of this product, though. Really the only issue was that there was very little protection for the servo from packaging material. This is why this category lacked the final point. I would like to see this changed as this servo could have easily been damaged by a not-so-careful delivery man. Overall, great job on shipping HobbyPartz, especially considering it was free!
Performance - 8/10
When I first put this servo in the test vehicle, a heavily modified Traxxas Rustler VXL, I was pleased to see that on flat ground the servo had no problem moving the aggressive tires I had mounted up front. The servo did it rather quickly too. Compared to the stock Traxxas 2056 servo that comes in the Rustler, this thing was great, at least on the workbench. I was pleased to see that the install went without a hitch and that all the needed screws and other hardware that was needed to install it was included. But, let's move onto what's more important - the actual performance when the vehicle is running. To put this servo to the test, I really bashed the test vehicle hard. In fact, so hard that several other parts of the vehicle failed while the servo just stood in there and took it without breaking a sweat! While the servo did not become damaged during testing, I wasn't as happy with the performance as I had expected. Considering that this servo is rated at around a 180 ounce inches of torque, I was expecting it to be easily able to turn those tires even in the grass. The servo did turn the tires, but not without a little more trouble than I would have liked. I could tell that the servo was being strained, when it really shouldn't have been. Otherwise, this servo performed great, with very respectable speed considering that this is a budget product. However, because the servo didn't seem to have quite the torque I was expecting, I deducted the two points.
Value - 9/10
While I definitely don't think that this is the best servo out there (or even close to it) it is a pretty good value. This EXI D226F shouldn't be used in any precision or torque demanding applications, but for backyard rc bashers like me, this is a heck of a lot better than the stock servo! The only reason I didn't award this category with a perfect score was because I think the material the casing of the servo is made out of could be improved. To be honest, I did not experience any issues with this myself; I have been hearing a lot about this problem, so I find it only appropriate that HobbyPartz should address this problem.
In the end, this servo made me smile, just not as big as I had hoped. But that is just one of the few problems with buying budget products - you really don't know what to expect. Hopefully though, due to this review, you do know what to expect and know if this servo is right for you.
