MadInventor 3884 Posted January 22, 2017 Haven't posted any progress on this for ages, but managed to get a bit more done today: Got the flanges to blend the rear of the trailer to front added on both sides, and got paint on this side. 8 Share this post Link to post Share on other sites
MadInventor 3884 Posted January 23, 2017 As it looks like prices in the model shops are going up, pulled the trigger on a 6S speedo for the tractor unit today and a 2.4GHz radio, so should be able to give it a trial run on the full 2400Watts on the motor soon. Can't wait 1 Share this post Link to post Share on other sites

MadInventor 3884 Posted February 2, 2017 Bit more done, Had to make the mask for the skull from a printed sheet of A4, so the result is a bit pants, but it'll do. Also got the front end painted so it all matches. 6 Share this post Link to post Share on other sites

As with armour-modelling, the hand-painted look looks pretty convincing to me, something primeval about it. Are you going to weather it a bit? I reckon a light filter of 1% base-colour to 99% thinner over the top to make the contrast a bit less harsh and it'll be perfect. Share this post Link to post Share on other sites

I'm just going to drive it on the some of chalk roads across Salisbury plain in the summer, that will cover it in fine powder, which will hopefully replicate the look in the film 1 Share this post Link to post Share on other sites
MadInventor 3884 Posted February 9, 2017 Tried the tractor unit rolling chassis on it's own on 6S this evening. I think it's going to be way too fast, haven't got any numbers on speed yet but I think it's doing around 30mph. Got to try and find a wide open space where I can open it up and do a good speed measurement, with tractor unit only, and with the trailer. Share this post Link to post Share on other sites
Biz73 603 Posted February 10, 2017 I can't remember if you said this before, but did you end up using a 2.4ghz Tx/Rx? Can you imagine this heavy beast running away at 30mph! This build is awesome. Thanks for sharing it with us. 1 Share this post Link to post Share on other sites

Biz73 603 Posted February 11, 2017 Good deal. I had this image in my head of your next on board vid clip being of you running away as the truck as it was charging full speed at you and you're screaming "oh crap, radio interference!" 1 Share this post Link to post Share on other sites

A little bit more progress to show: Receiver and ESC install. The ESC is massive (Compare against the size of the servo), but it is good for 6S and I spent some time today making components (The horizontal tubes) for the front blade: I made these from solid stainless steel rod, and they form the backbone of the blade. I'm going to try and make the vertical strakes from steel, but need to find some 3mm thick steel plate from somewhere. 2 Share this post Link to post Share on other sites

MadInventor 3884 Posted February 25, 2017 Got some video of the truck today. 36kph tractor unit only, 32kph with the trailers on. Feels way too fast and unstable. The battery dumped after about a minute so I don't think they were anywhere near fully charged. I think I'm going to have to rebuild the gearbox with a much slower gear ratio. 8 Share this post Link to post Share on other sites
Jason1145 3986 Posted February 25, 2017 That looks pretty cool trundling through like that... will look so much better with the front cab attached... just need some FAV's running either side of it for security convey detail. 1 Share this post Link to post Share on other sites

Yeah, it's starting to get there now. This was the first time I took it out and returned without thinking, I've got to fix that, and that, and that's a problem, and that failed, etc. I kind of already knew about the gear ratios from previous runs,so I wasn't too disappointed with it.

MadInventor 3884 Posted March 5, 2017 So, had a bit of extra work to do on the Rig this weekend. Took it out this week to figure out how fast I wanted it to go and settled on 28Km/h as a sensible and controllable top end. Then decided to give it a rip round a nearby BMX track and it took off over one of the jumps and one of the front shocks flew apart when it landed. I found the thread on the shock end had been stripped, so have made 2 more shock ends from aluminium: 3 Share this post Link to post Share on other sites
MadInventor 3884 Posted March 12, 2017 Have now painted the from axle assembly, and painted and fitted the aluminium shock ends. I've also painted the chassis rails but no pics of those yet. Also got the gears from HPC for the speed reduction required, so now got to design a new gearbox to accommodate it. 2 Share this post Link to post Share on other sites
Jason1145 3986 Posted March 12, 2017 Yes it sounds like it just took off from the BMX jump all by itself and had nothing to do with your throttle inputs! It takes a strong constitution to not jump an RC when presented with any sort of incline, at least you came back with a stronger fix Share this post Link to post Share on other sites
