Its time for another product review. A brand new servo manufacturer was kind enough to send me one of their new brushless low profile servo’s a few weeks ago, the RC OMG HDT045070B. I’ve been using it in my competition drift car since then to give it a proper test. Read my test results after the jump.
First, let me give you some specs of the servo. It is a low profile, brushless, digital servo. On 6.0 volt (which we use in our drift cars) it has a speed of 0.06 seconds, 5.5 kilograms of torque and it weighs in at 45 grams. Also, it uses a 25 teeth spline at the end of its titanium gears so you can use Futaba servohorns which is the most used size so you probably have one. The size of the servo is about the same as other well known low profile servo’s like the Savöx 1251MG and the Futaba S9550, maybe even a tiny bit smaller.
When you open the box you’ll find the servo packed away nicely in a lot of foam. The box with the servo in it was smashed, but the servo and packaging survived without a scratch. Strong packaging from RC OMG! Underneath the servo there’s a bunch of screws and servohorns, but I didn’t need any of those. Remember, the servo I have is a prototype. The production version will have the OMG logo and productnumber printed on the servo.
And this is what the servo looks like unpacked. The aluminium heatsink is anodized in a nice dark orange/red colour, and although its not a perfect match, it doesn’t look half bad in my red Yokomo DRB. The servo has a very long wire with a JR servo plug, so it fits in every car with every reciever.
I’ve been testing the servo in my Yokomo DRB, and so far I’ve used it for about 30 battery cycles. I am very happy with the servo. It is lightning fast, and also very precise. I was a bit worried about the 3,2A stall current that it has according to the specsheet, as the BEC of my ESC (Hobbywing Xtremestock) is only 3,0A. It does have a set of capacitors on it, but I’m also using a lightkit for my bodyshell so this made me worry that the servo might glitch. But so far it has not skipped a single beat, it has been working perfectly all the time!
In conclusion then; This servo has plenty of power, it is ridiculously fast, its very precise, it looks good, the dimension are perfect for a modern narrow chassis like the DRB and so far it has been very reliable. If you are in the market for a new servo you should really consider an RC OMG servo, I can highly recommend them!
