Just one fellow's experience(me), but the cheap esc, and to a lesser extent,the cheap motor, route, for F3A electrics, don't work out too cheap in the medium-to-long term.
I started out with a cheapish far east ESC, which failed on flight one,due to the high current draw of the hotter of the two then-popular Dualsky F3A motors.
I then used the CC 85HV ESC ,which coped fairly well with the Dualskys, until one of the Dualskys burnt out, and took the CC 85HV with it.
Since then,I've had literally hundreds of trouble-free flights, along with many more useful extra facilities,offered by the initially more expensive jeti spin 99 ESC,and its jeti box companion thingy.
This has been with the AXI F3A motor.... a bit on the heavy side, and relatively noisy IMO, but powerful and reliable, for me at least.
Also I have used a couple of the Plettenberg 30-10 evo motors,(most used of all), and they have been superlative in any respect you could think of,except for the initial cost.
But over two or three seasons,cost per flight, the jeti/pletty combo has been easily the cheapest,I'd guess....
Again just my experience, but where you can save(and this is becoming more so each month almost) is with the cheaper battery packs now available.
Provided you can afford up to about four ounces extra weight, I've found that my Rhino 4900 5sx2 F3A packs are slightly more powerful,with slightly higher residual voltage, than my "generation 3" (latest ) Hyperion 5sx2 5000 F3A packs,at about one third of the price.
Moreover,both the Rhinos and the Hyperions, are well ahead of my original Flightpower F3A packs, in terms of keeping low IR numbers, and in terms of numbers of schedule-capable cycles before deterioration.
