Got my el cheapo 17.5 /60a speedo combo yesterday..Didnt have time to put the speedo in before i went racing, but I did run the 17.5 in 2wd buggy, blinky esc class just ran it with my Hobbywing 60a I had in the buggy..These motors are JUST FINE for club racing in blinky mode.I was just as fast as I usually am and made the A with no problem.It was actually faster than the 3 yr old Orion 17.5 that I have been running in that class which was expected since the orion motor is 3 years old...Looking at the speedo up close it IS a hobby wing just as suspected, just has a different Cap. module on it..will be getting the yellow speedo in my buggy for testing at next weeks races..Mr .Ypin2000 (ebay seller) should be giving me a kickback at this point,LOL..Have quite a few peeps at the track looking at these pretty hard after scoping mine out last night...
