I would only get the tekin if I got the rs pro. The hobbywing stock spec pro v4 is the way to go for $120. If you do want to make changes, make one change at a time, and test to see how that changes impacted the performance.Īdditionally, I have seen 100+ amp current draws from my 17.5 2 2wd buggy on my data logging, so I would try to get an esc rated for at least that much.Those current draws are burst currents and the stock spec pro v4 can handle 380A burst on the manufacturer's website. This is where a more experienced person could help you optimize your esc settings, but if you buy a nice esc and leave the settings alone until you really should be good to go. Conversely, if you are new, a bunch of settings will probably hurt more than help. Second, the more adjustments an esx has the more potential you have to make the esc work best for you. They may even be better as the firmware is specifically designed for blinky racing but I don't know that for sure.įirst off there is a Radio & Electronics section, and this question should definitely be posted there. They are specifically designed for it so well within spec, cheaper, lighter, smaller etc. So Hobbywing Just Stock, Orca B32, Muchmore Euro v2, Maclan Pico etc. My opinion (remember just opinion so could be wrong) is that the stock type ESC are the ones to get for stock racing. Remeber the ESC has 2 amp ratings, continuous and burst, so the 80/100amp stock ESC will have a burst of 320/400ish which allows for those spikes over the continuous rating. Bascially it was worth getting a combo for me as you get a combo discount and I wanted to upgrade very cheap trackstar gear. I needed a new motor which prompted the ESC question so I ended up with the Orca B32 (equivalent to the Just Stock in your list) and the Blitreme 17.5T motor. This is based on thr manufacturing, a lot of componenets are graded for quality and the best go into the best, then next tier down, finally the cheapest get the ones that are good enough that they aren't junk but not great. My feeling is a very cheap one like the trackstar could be as much as 10% less efficient than a top model. However, the better the ESC the higher quality components used in them hence they are more efficient, so they will be marginally better than a cheap one. Take advice with a grain of salt as it depends what they are selling. I've also been told all sorts like stock racing (I run 17.5T blinky too) needs a better ESC than mod as it needs to deliver more current for the 17.5T to clear the double. This makes sense to me and the guy who told me is not only smart but this is also his day job. So as long as the ESC isn't horrendously inefficient then it shouldn't make much difference. I asked this same question recently but of different ESC, Trackstar 80amp turbo (cheapies that I have), Speed Passion Reventon Pro 1.1 (better ESC I have, old but was good in its day) and a new one (whatever the hobby store had for sale).Īn electrical engineer friend said the motor determines the demand for power and the battery delivers it, the ESC sits between.
