Video of the tamiya heavy dump truck, which is on the gf01 four wheel. Drive chassis i’ll also be showing you the modifications i’ve done to this compared with a standard, build uh, but first up i’ve done a little speed test with this. So let’s have a look okay, so the setup for this is uh. It’S got a three and a half thousand kv, brushless set, which is the absolute thrust. Combo uh about to be precise, it’s, 3421kv and i’ve got a 2s lipo battery in here also, i’ve got the 20 tooth. Pinion you’ve got a choice of the 18 tooth. That comes with the kits or 20 tooth uh, you might notice i’m running it with the chrome wheels. Only reason being is that uh the tires on those wheels haven’t got the spikes, because i don’t want to wear down the spikes. The standard tires it’s worth saying this isn’t, the sort of kit you buy for major top speeds, it’s fairly low geared so yes, 22 miles per hour, not bad for something like this and i’ll talk more about the performance of this in the review. Part of the video okay, so onto the modifications that i’ve done to this compared to the standard build. I have covered a lot of this in the three build videos that did this, and also there was a separate video to show how you can use a lunchbox. Bumper on this, which is much stronger than the standard one, so, as i mentioned on the speed test bit, i’ve got a brushless combo in this and also put a steel 20 tooth pinion.
You need one that’s 0.6 module also put these side bars on now. These bars are included in the kit because they’re not part of the standard, build because you do need to do a little modification to the rear body post to make them fit. So i think these give a nice chunky. Appearance to the truck uh also gives a bit of protection to the servo on the side there and there’s another advantage, which i’ll show you on my other gfo one right. Okay, so on this one that’s, the uh broken one of the rear body posts, and so it was a bit stuck as to what to uh attach that to to attach the body and um. So i attached the side bar there and then the body post attached to that so yeah it’s a bit um more flexible than these. These are quite hard plastic uh, and so, if you land on each roof too many times, you might break one of those. But i say these sidebars are nice and flexible and, having broken that body post, this went straight on uh, you know all you’ve got to do at the front is to take the screw out, put the sidebar on and then put the screw in through that. Just get yourself a bit of a longer m3 screw and um for the side where the posts were still there. You do have to trim it down. I’Ll just show you okay, so you can see i’ve just cut away the uh little arm there, that’s attached to the chassis, so it’ll fit the bar.
There just need to take a little bit out the uh bottom of the bar there just uh. This plastic is very soft, so you can just trim that with a knife, just uh felt all that until it fits so i’ve done the same thing here on the dump truck. I don’t quite understand why tammy didn’t uh incorporate these into the design really so an advantage to using the sidebars with the dump truck here is that it’s got this sort of hook, part here which attaches the cab section to the chassis and that will come unhooked Uh after you roll it over several times, but with this sidebar it helps to sort of keep that hooked into place properly, but you can still detach this. If you need to you, can you know, take the body pins out and hinge that up? Are you helping Music richie, so i replaced the friction shocks that came with the kit with these tamiya mini oil shocks uh. It gives a much softer ride. Also, i thickened the oil and went down to the uh piston top with the in the one hole in to start with. I was using the kit springs, which are these, which is still a bit too hard for the weight of this kit uh, and it was still a bit bouncy. So i’ll show you the previous drop test, so so these springs i’ve got. These are the ones that uh go with the tamiya mini shocks generally, so i’ve got some of these and say it’s a bit bit softer now, which i think is more appropriate for the weight of this truck.
So let’s just try a new drop test, so you can see it’s still uh still a little bit bouncy. I think the trouble is is um they’re, not very long. I mean there’s only that much travel so you’re never going to get a soft landing like a truck with great big long shots but um. I think that’s about as good as i can get this i mean it is supposed to be a fun sort of um, bouncy kind of roly, poly truck so anyway, i’m happy with how it is now. So i think, should happen with a off road truck is, if you press, the suspension where it comes to rest, should be below the um top of the travel of the spring, so it should sort of sit somewhere in the middle um if it’s sitting right on The top, i think the suspension is too hard for off road, so say i think it should sort of rest somewhere in the middle there, and this does now. So you can see a bit easier on my yeti here. What i’m talking about, because uh it’s got nice long shock so where the suspension tends to rest is somewhere in the middle there. So it’s got um more travel downwards and a lot more travel upwards as well. It tends to rest somewhere in the middle. What you don’t want is uh, so much damping, actually that you push it down it: sort of crawls up or sort of sticks down it.
So there’s a bit of a balance between the amount of damping you have and the strength of the springs but sort of get a feel for it and uh yeah. That feels pretty good. Also, i think you should be able to pick up one wheel and it can press the spring most of the way before the other wheels leave the ground. I have got a battery in this, so it’s the weight that it would be while it’s running so yeah. I’M sort of happy that’s about right now: okay, so that’s about all the mods let’s move on to the review. So is this worth you spending your hard earned money on? In short, yes, it is uh, but it depends what kind of thing you’re after um, if you’re after something to go around corners quickly on grass and everything, then probably you want a buggy but um. If you want to do sort of this kind of thing, uh off road and sort of just messing about – and this is uh really good fun – i haven’t actually seen anyone speed test this with the standard brushed motor at a guess, i’d say it would go about 12 miles per hour, which is probably okay for a smaller space. This is a bit of a handful on brushless to be honest, but uh yeah, it’s amusing, sort of trying to control it uh. You could just use this with the standard kit motor and have it sort of like a trail truck.
I mean it’s, quite versatile and being four wheel drive. It doesn’t get stuck too much um. So yeah i mean it’s, not a crawler. Hasn’T got sort of very soft suspension, as we were previously saying, but um it’s pretty good. It can go over most uh ground and say it’s good fun, it’s a bit like a four wheel, drive lunch box and that can only be a good thing. I was trying to decide if i like this saw the lunchbox better. I can’t quite decide really. They both got different uh and amusing handling characteristics um. So i think you’d be happy with either of those kits but uh check out the build videos i’ve done of both to decide another alternative to this would be the kong head, which is a bit more stable as being longer it doesn’t wheelie. So much and it’s better at getting up slopes a little bit more expensive, but that’s. Also a great kit. I’M broken this one as yet, apart from the bump, which i previously discussed, um so it’s tough and i know for my previous gfo one the gearbox is going on and on. I have replaced the pinion, as i said, with the metal one, the steel one rather than the aluminium one, but other than that.
