If ESCs are your problem, do you really want send it back to them at an expense of 10-15$ and wait for that to come. It would be better to go for widely available motors so that in case if it need replacement you can change it quickly and need not wait for long time. They are really expensive but are slightly more efficient may be 2-5% but I dont think you need to spend very much for that instead you can go for bigger motor from some other seller. Suppose a cobra 3515 56$ has an efficiency of lets say 85% buy emax 4114 at 45$ which are more efficient . Efficiency I mean is gm/watt ratio. |
