From ABS, or what are you printing (assuming you print?)?

 

I did not order the Kronos, but i did order the Dementor, arrives tomorrow. Do you have an example piece for a different RC or something? Price?  

I can print from Polycarbonate or Nylon if you prefer. Just had a delivery of a hardened TPU... but no experience with that one yet so I wouldnt be confident offering it to anyone.

 

I can alternatively cut them out of kydex/UHMWPE/Nylon

 

I havent done a mudguard yet, but happy to work with you to get one designed and made and would only charge somewhere around £5-10?

 

Here are some other parts I have been making. Black is polycarb and grey is nylon. A bumper/mudguard is relatively straight forward in comparison.

[m4inbrain]

They look pretty good, what are you printing - 0,1?

 

Price is fine, lets make a set then. I assume you need measurements/pictures, and design-wishes?

They were 0.2 IIRC, I tried 0.1 and didnt gain anythign for the extra time (IMO).

 

Yeah exactly.

 

I had something like this prepped for arrma... but never got round to making them

[m4inbrain]

I don't know any measures, or how similar the arm/space back there is compared to a Kraton. My neighbour does indeed now have a Kraton since wednesday, i can compare that tomorrow (truck arrives tomorrow). 

 

Lets not clump up this thread further, i'll PM you. Probably gonna order a set for the Kraton v4 too, i think me neighbour wants mudguards too. 👍

 

edit: actually going out the front for a vape with neighbour, gonna PM in 10 minutes, then i know.

Click his name on the left, in his profile on top there's two orange buttons - the one with "Message" is the correct one. [emoji6]
 

Thanks!

Corallybuddies now.

 

Does the Kronos come on the same tyres? They do seem to balloon quite substantially even on 4s?

[Goddinaw]

The dementor looks smart. That was a great deal you got on it. I think putting some thick oil in the centre diff should reduce the ballooning a bit. I used 300k for the centre.

I’ve got 500k in the centre of mine and yes they are the same wheels/tyres

[m4inbrain]

So between 300k and 500k in the center?

 

Had it out for a second again earlier, to show wife her new truck - i did get the impression that it requires a tiny bit of tuning.

[.AJ.]

Anything over 200k is definitely needed in the middle 👍 

[m4inbrain]

500k coming tomorrow, so that's going in then.

 

As a sidenote, for people interested: yes, you still get the "upgrade part offer" with a new Corally. 

 

I did get the option pack 1 for free straight with the truck - registered the truck and now got the code for the bigger option pack at £35 or something, with a 77% discount, which i'll of course order too.

 

Big respect from me for that kind of service. Almost makes me forget the stupid name of the truck.

 

edit: just took diff out in preparation for tomorrow. Man, a truck set up for racing (or made by people who race) are convenient to wrench on. Four bolts and the centre diff comes out, less than 2 minutes to get it out and back in again. Awesome.

Well.. 

 

 

 

 

Kinda disappointing, not going to lie here. This wasn't a big hit, it wasn't concrete either, not even running 6s - did a wheelie, hit a grass mound, bent the truck in half. 

 

It's hard to convene how soft i went on the truck, it's a new RC so obviously i wasn't thrashing it. I almost wanna say something is wrong with my chassis plate, it bent so easily.

 

Very disappointed, gonna message Corally and see what they think.

That sucks!  Maybe Coronavirus weakens plastic? 😯

Chassis is aluminium.

 

Not gonna lie, i can't imagine this being right. The Kraton with us had some big hits (was running 6s too), even broke his wing mount straight off - straight as an arrow, his chassis. Ours got babied, ran 4s and never full ham, bent more than i've ever seen an RC bent. 

 

So disappointed.

Must be a defect, I mean these are meant to be hit hard or what's the point?  Fingers crossed they do the decent thing! 🤞

[.AJ.]

Sorry to hear about that, the big reason I bought the Kronos instead of a Dementor is because of the extra rear bracing 😬 

 

[m4inbrain]

Well even without that.. It bent like 30 degrees, a second brace wouldn't have done much. 

 

Alas, fix it, repeat. Though, by chance, do you know anyone making chassis for Corallies? As in, 7075 maybe, or a mm thicker?

[.AJ.]

I’m guessing when the race kits will be released there will be a 7075 chassis available, Corally make alloy brace and there is also this guy on FB making chassis reinforcement plates soon, 

 

[m4inbrain]

Much appreciated, since i'll need quite a few parts, i'll scavenge through corallies stuff and shoot that guy a message. 

 

Probably gonna send corally a message too, in regards to 7075 chassis. 

 

Cheers bud.

[No brains]

mmm I was temted to buy one myself, but this is not  good , I am  happy that I don't bought it,

 

I hope that corally send you the parts for free and  give you some extra chassis alloy brace as a bonus.

 

Is the chassis made of cheese never saw something like that happen only from a wheely,  I have a cheap hobbyking Basher nitro circus mt 1/8 scale for years, beat the crap out of that car every time and it never breaks or bend still happy with that car, but when I see this or arrma cars that bend I ask myself what the .... are they doing these cars are not cheap.

Let’s bare in mind this is a Kronos thread, not a Dementor. I’ve bashed my Kronos and had plenty of spills and crashes with zero issues apart from a bent turnbuckle and the shell is looking a bit worse for wear.......

 

 

[m4inbrain]

What he said.

 

Did take it apart a bit, and i have a pretty good idea as to why the Dementor bent, and the Kronos doesn't. 

 

For now i would suggest not buying a Dementor, i'll look a bit "deeper" into that but i'm pretty certain there's a huge design flaw in the way they mount the wheelie bar (something that the Kronos doesn't have) to the bottom plate. To be fair, i ran the flimsy braces rather than the upgraded braces that they did give me with the truck - i'm not sure it'd have prevented that, but it certainly would've helped. I'm gonna fix it, it's an RC and it will break regardless of what i do with it so i'm not too bothered - but i will get rid of that wheelie bar and figure out a different solution. I will also give Corally a shout of course, because 100% the reason the truck bent is the wheelie bar, which is evident by the fact that the wheelie bar basically bent the shaft between the wheels on the second wheelie already. The only give in that wheelie bar is through the chassis plate flexing. 

 

Oh, and i will run chassis braces now, lol.

 

There's no reason to get defensive btw. 

[Goddinaw]

Just made some socks for the shocks - I use braded tubing - I’ve done it on my other cars but need to get a larger size for shocks on the Kronos.





The last picture is the tubing. I used the 25mm for this car. It works out quite cheap and has been hard wearing on my other cars.

Thanks to Paul Busby for the bumpers - they look great and are strong and flexible, so should be perfect for my inevitable mistakes.
