My first truggy, setup q's

[E-Revonut]

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!

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!

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
