Am trying to find the right ESC for the following two motors



Can't figure out which of the ESC's listed on the site would be best? Are there alternative (cheaper or better?) options?

  • $\begingroup$ To make this question more useful, consider copying the relevant motor (and ESC) specs from the linked pages into the question itself. A good answer will explain how to read those specs and make the right decision. $\endgroup$

Looking at the second, I see 62 amps continuous, 75 max burst, you want a brushless speed controler that can handle that, assuming you plan on using the full power of the motor. So, from that vendor; http://www.e-fliterc.com/Products/Default.aspx?ProdID=EFLA1080B

It takes some looking, but the first motor is a replacement for a kit. That kit comes with a 5 amp speed controler/receiver combo - so you would need a 5 amp brushless speed control. http://www.e-fliterc.com/Products/Default.aspx?ProdID=EFLA1005

That is quite a difference between the 2, power wise. You need to think about physical size and power requirements. Then I'd recommend cheap chinese verson instead; hobbyking

Just remember, brushless motors need brushless speed controlers. other than that, match up potential amp draw to speed controller capability. Choose batteries based on intended length of runtime. The battery C rating indicated how much current it can deliver. A 1000mah battery rated at 20C can deliver 20 amps.
