My first truggy, setup q's

[el tomaso]

Hi

I finally found a truggy roller that I liked, I have been looking for a while. I was looking for one of these, Hyper ST Pro, MBX6T, D8-T, and RC8-T(only if I could get the RCM full chassis conversion).

I eventually found a dirty, but otherwise lightly used Hyper ST Pro roller, with a box full of parts, torsen diff, extra spider diffs, arms, shocks etc. No nitro stuff, because I am converting it to BL

I recently fell on som icy trail when walking my dog, and my kne was twisted out at a very unnatural angle. The following period of recovery was spent at the workbench, getting the ST back in shape. I cleaned it very well, and rebuilt the diffs and shocks.

I bought a cc/neu 1518 1y 1800kv at the sale, knowing I would find a good home for it. I have the cc 1512 1,5y 1800kv in my hyper 8,5 Pro, and IMO its the perfect kv for 6s

Rest of the setup is MMM, 6s 4000mah 40C turnigy and a digital strong servo. I use mikes mount and the D8-T tray with esc shelf. I had to modify the underside of the tray to get it to fit without hitting the spur. I also had to use a MBX6 mudguard on the left side so the batt tray isn't hanging over the edge. Not symetrical, but looks good.

I only had 10k and lower diff oil, so I am trying 10k 10k 10k The spider diff doesn't need as thick oil as reg diffs, so 10k in the spider center diff could be enough. I am going to buy more oils, anyone know what oils I should use F, C and R?

I can not wait to try the truggy, hope the weather changes.

I'll get some pictures for you soon, so my thread can be worthy

I took the truggy with me to a family visit closer to the ocean, and there the snow had melted away. The reason I had it with was just that I need to see it every half hour when its all new and shiny(used and dull, but clean)

I got to try it on a big dirt parking lot. At first I could not get the esc started, when I flipped the on/off switch nothing happened. I tried resetting the TX, tried several times, then suddenly it started. The power was slow and glitchy, so I turned it off and checked all conectors. Nothing wrong, so I turned it on again.. It finally worked normally, or should I say extremely awesomely

I loved the feeling of the driving the car, first time I ever tried a truggy and I loved it! The castle/neu 1518 1800kv on 6s was very fast, and had a lot of punch.

Front tires balooned a lot if I was agressive on the throttle, I need to tape the tires and get some thicker CD-oil. Fron't and rear diffs felt fine with 10k though. The shock's need thicker oil and stiffer springs, but they worked fine for now. Not that its needed, but I see big-bores(the hyper 9e ones, to match my hyper 8,5 pro) in the near future Otherwise everything worked great

I didn't recieve the turnigy 6s 4000mah 40C lipo yet, so I only drovew for 8-10min to not melt the 6s 3200mah 30C loaner battery.

I will post pics when I get home to my camera.

Now you can see the different mudguard on the left side, to make room for the batt tray, which is the one from the D8T conversion. Didn't fit without modding the underside of the tray, but now its great! Maybe I should triy the MBX6T mudguards on both sides to get it looking symetrical, but thats maybe.

You can also see the spider diff in the center, which I like.

Looks good, u may want to consider a RX case?

[bigboi146]

Yours is set up exactly how mines used to be set up. I just drilled a hole for the antenna and velcroed the receiver there. And as for the mud guard who makes the one that your using on the left side?

[el tomaso]

The left mudguard is of a MBX6 chassis I had left from a tekno conversion. I am going to buy the MBX6T mud guards for both sides later I think. So it will look better, and keep the dirt out.

I got my turnigy 6s 4000mah 40C lipo, now I just need som good wheels and tires. Anyone know som premount wheels/tires for truggy that will handle the BL? Preferably cheap

And a new body.

I am now waiting on some 50.000 oil for the CD, and some VTEC kamikaze premounts that I hope will survive with some throttle control In the meantime I am testing my new LRP buggy, with great results

The premounts and 50k oil came just after I posted earlier, I quickly took apart and cleaned the centre spider diff and filled it with 50k. Damn that stuff is like honey, thick I reasssembled the truck having never removed the 1518 from the mount, I thought then I wouldn't need to set the gear mesh again.

When done the car wouldn't move, the spur was locked against the chassi. I almost installed the regular diff since it has more clearence, but I tried again without the heavy motor on the mount. Luckily that did the trick, the spur now just clear the chassi.

I first tried the wheels/tires I used earlier that came with the used car. I was happy to find that with the 50k the "old" tires worked fine with only normal/tolerable amount of balooning. So now I have nice balanced spares for when those are worn. The VTEC premounts looks just perfect, I am looking forward to trying them.

The diff setup was now quite good for someone without much truggy experience, like me. (f-c-r, 10k-50k-10k). Might try 20k in the front. I only got to empty half of my battery, because it started raining but OMG truggy's are FUN! The 1518 is a beast. I have another motor I wan't to try as well, a feigao 580L 8L of 1600kv Before you laugh at me, I got the motor almost for free and I want to know how well it can do in a truggy.

If your olny going to bash with it then yes something along the line of 20/50/10 will work fine, maybe even 50 in all 3. For racing you would want much lower, I have used 7 in all 3, 7/10/5, 7/10/3, and 5/10/3. I have done so much since the 7/7/7 that I need to try it again because I seem to remmber it handling best with that. However I must say that on a track tires have the biggest impact on how a truck handles!

[el tomaso]

Sadly there are no tracks near me, except for touring cars, which I've never found interesting. So its only bashing for me, but I like my cars to handle well.

I tried the 580L 8L in the hyper ST today, it seems like a more powerfull motor than people give it credit for. My run was cut short when the rear internal diff-gears turned into a mix of silver shavings and diff oil First time I ever had to replace a diff Luckily the previous owner of the car had several extra diffs that I got with the car, so I fixed it quickly and now I am going to do further testing with the 580L.

I'll report back afterwards.

The Feigao 580L 8L 1650kv is a great motor IMO, almost as good as the cc/neu 1518 1y 1800kv in my truggy. I love saying that "my truggy" I ran a whole pack 6s 4000mah 40C through the MMM and 580L. I geared it with a 16t pinion with stock spur, same as the 1518, and the motor came off at 160f after the run. Esc and batts were under 100f, fan was not on at all.

160f is about 20f more than the 1518 which came of at 140f in the same setup. So thats the difference between the quality of the two, 20f. I am going to use the 580L for now, I could wheely at will, but i don't have to.

The diffs are now (f-c-r, 10k-50k-ball diff grease) I didn't have the 10k with me for the rear diff, but it drove just fine with lots of BDG pakked in the rear

I also had problems with the MMM needing to be turned off, tx off, then tx on-> MMM on, when I drove with the 1518. With the 580L this was not the case...........hmmm.

Well, the feigao got very hot one run, like 300f, so its back to the 1518. I have been driving as much as I can with the varying weather around here. Managed to blow the rear diff again.

FIX: I have ordered two spider diffs for front and rear, along with matching pinions, shims and also 20mm big bore dampers with hard springs. This truck is going to be a tank!

Thomas G

[el tomaso]

Now I think this Hyper ST Pro is as good as bomb-proof. I have installed spider diffs front and rear with 10k oil, to match the spider center diff with 50k. I got the diffs for half price, because the store I bought it from wasn't sure they would fit. I needed to change the pinions too, and that was it.
I have also installed the 20mm big bore's, with the stiff gray springs and 35wt oil. Is this too light oil for a truggy?
After a couple of runs I am happy as can be, the handling with the spider-diffs and big bore's is MUCH better. It also jumps great
I am now driving with MMPro, 1518 1800kv and 6s. I knew the MMPro could move a truggy, with the right setup

That sounds like a real nice truggy you have there.

With the MM Pro are you using a external BEC or another type of capicator?
