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
