HuiNa Excavator 1593 – #1 What's In The Box
This is the recent 1593 version which, as i understand, is more or less the same as the older yellow ones, but with a bit more oomph in the rams, so you can actually move stuff around without them struggling plus its green. The digger is supposed to be 1 14 scale, but, as usual well find its a bit smaller than tamiyas idea of 1 14., its probably closer to 1 16. Really, i wont let that detract too much, though, as long as we can have some fun with it. Thats, what matters most the box it comes in is pretty big and fairly well decorated. It doesnt quite have the shelf space wow factor of a tamiya, but i think id probably check it out. If it was on the shelves of a real model shop, it could do with some more details and stats to get the juices flowing. Though one thing the box does have going, for it is its got. An enormous reinforced handle itll actually take the weight of the digger without worrying too much about ripping the cardboard with a bit of thought. The box could work pretty well for storage and transport. The digger does, of course, come with a manual youll have to keep in mind that this is really just a rather nice toy grade, rc rather than hobby grade, so its not the most comprehensive but theres enough in there to tell you what the controls do and How to deal with the battery if we lift the top off the polystyrene insert, we get to see the digger in all its upside down, glory again being toy grade.
Its completely ready to run all youll need to do is power it up and off its going to go speaking of power. We have a 2s lithium ion pack for power. Its got separate power and balance leads so its going to be simple to charge it with a hobby grade charger its only 1200 milliamp hour, but it should run the digger long enough that youre going to get bored first, when the suppliers at the shops are a Bit better, we might make a high capacity 18650 pack, so we can leave it turned on all day. The digger comes with a usb charger whose output is rated at 4.2 volts and 800 milliamps, which is a bit strange as lithium ion packs, are much higher voltage. Im going to guess theres a bit of a misprint there, but either way its going to take 90 odd minutes to charge the included pack from flat, which is good enough. Id still recommend using a proper hobby grade charger, though that does lithium ion its easier to identify battery problems before they become big problems. The transmitter is a bit of a strange one, its some freakish playstation, like thing its obviously designed for a smaller hands and mine, and the gimbals are just awful designed for thumbing, rather than pinching, but thats possible as again its a toy digger. So its going to be targeted at people, whove grown up with a twin, stick console joy pads. The only other thing in the box is the digger itself, which just lifts out ready to go.
It feels nice and solid with lots of heft, which is rather important. If it were lightweight, it would tip over the first time you had any weight in the bucket and speaking of the bucket, its metal, which is a nice touch. Most of the rest of the digger is plastic, of course, but it does make it feel like its got, some quality to it. Oddly, a couple of the fake hydraulic lines have popped out of their mounting holes, not sure if thats intended or not, but its simply enough to press them back into place right power first well need to power up the transmitter on the back is the bay for Three double a cells, but to stop kids eating them. Its kept closed with a small self tapper once removed the covers still clipped in so we wont have to bother putting the screw back in. We need three as to pair it im, not sure how long theyre going to last, but its probably going to be a really long time, because its a modern, 2.4 gigahertz radio, if we turn it on the red, led, starts blinking, which i believe is kind of. Like its bind mode as its looking for a digger to talk to on the digger itself, we need to remove the battery cover at the back its fairly well hidden with a little twist latch to secure it. All we do is twist the lock 90 degrees and lift off the cover to reveal the red bec connector before we plug the battery, in though well need to make sure the power switch is off just in case it decides to do something daft when we connect The battery okay, now we can plug the battery in refit, the lid and twist the lock.
Now, probably due to not watching what im doing, we seem to be missing a bit of footage of the initial power up theres, not much to it, though the manual simply says turn on the digger and transmitter to bind them with no particular order, not the clearest Instructions, but it seemed to work okay, whatever order, i did it in everything, went just fine the annoying bit, though, when you turn it on. It comes up with the red and blue party lights in the cab and the most annoying engine. Sound ive heard since playing racing games on a sinclair spectrum. Okay, well its not quite that bad, but at least by pressing the two big buttons on the transmitter. You can turn the lights and sound off and now back to the live action. The manual says the digger has 22 functions, which seems like quite a lot im, not sure how theyre counting them, though, because i make it eight, maybe 14, if you count the up and down separately, that doesnt really matter, though its a digger with digger functions. Okay on the right stick: we have the bucket control on the left and right, stick movement, the left, stick, left and right rotates the cab up and down moves the arm and up and down on the right stick moves the boom. All of these controls are fully proportional, which is rather nice and, despite the slightly dodgy gimbals on the transmitter, you do get a good level of control, certainly enough to be able to load up a truck without crashing into it.
The rams seem to have plenty of power too its not the best test, but theres enough oomph to lift the digger by the arm without anything sounding like its struggling. The gear trains are a little bit noisy, though i think the only thing with the stock setup thats a bit disappointing is the drive, control theyre on and off, not proportional. So maneuvering is a bit of an art. You have to dab the buttons to move in small steps, its a relatively minor gripe, though, once youve got the digger in position, youre going to be using the rotate and arm controls most of the time, and since we didnt get to hear the sounds at the Beginning were going to turn them back on yep. All we get is a constant grumble. Then, when we move the arm, we get a different grumble. I think even the old heng long tanks have a more interactive setup, a shame, but at least you can turn it off from the transmitter. The other button turns on a red and blue flashing light in the cab, which is a bit strange. I seem to remember the old, smaller digger would play a tune with the lights, so it might just be a vestigial feature. It would have been better if theyve replaced the cutted lights with some white ones. Maybe a bright spotlight looking down in front of the cab and thats about it, for the digger ive not gone out digging with it yet to get it dirty because the plan is to pull it apart and fit some hobby grade electronics.
So we can actually use a decent transmitter. Thatll give us a more precise control, plus proportional driving controls. Ive not decided whether we should use off the shelf, escs and radio gear or designer drop in pcb, with most of the gubbins ready to go either way. It should make for a fun project.
