Awesome to hear the Fiorini is working for you.... The JPX has alot of bottom for a .21, so if any ..21 can pusha Fiorini a JPX can..... I use a Fiorini in my onroad, but prefer the snappier M2C in my offroads...

As for comparing Mugen to HPI, I was talking Crown and Pinions..Mugen uses a higher grade then HPI does.... We could argue all day, but you will never in a million years convince me a Hellfire has the same quality diffs a Mugen does... I got 45 gallons now on my original diffs on my 5T running all modified engines, no way in a million years will you see that with a HPI product..next time I do a diff service I will snap some pictures of my gears to show the wear on them..... Right now we are doing a head to head between a Mugen MBX6 and a HB D8, 2 local brothers bought one of each and run with use every week, we will be doing a final verdict at the end of the season.... So far the Mugen has broken 1 rear bulkhead, which Mugen replaced with a updated part, the HB has broken 4 so far ( rookie drivers with lots of crashes)..the HB is showing alot more plastic wear then the Muegn is so far...we haven't checked the diffs yet, but at the end of the season we will compare diff wear.... I like the HB, but I definitely am not seeing it having the same quality as the Mugen...both machines handle great and perform awesome, the HB is breaking a little more and wearing a little faster.... But breakage can just be luck of the draw, however how the plastic, diffs and outdrives wear will tell the full story, but that kind of wear takes gallons to see..on initial driving you wouldn't tell the difference between the two..... Next time out I will check the outdrives and see which ones are slotting more.....based off my years running all the different brands nothing wears as good as the Mugens do..... So I wouldn't be saying the HB is as good as the Mugen just yet, as so far in a head to head the Mugen is holding up better showing less wear and less breakage... Both brothers are my customers, so there is no bias going on whatsoever, both machines compete head to head with each other very well, and IMO the only advantage I see with the Mugen is its a little tougher...performance for the dollar the D8 is fantastic ! I hope this doesn't offend anyone...
