Tested KV:2570kv

Since the release of the original RS motor, Emax has dominated the miniquad motor market with it's combination of performance and price.  The RS-S line has continued that trend with the 2300kv and the 2600kv. The build quality on the RS-S line is amazing, showing some great improvements on the original RS line, traits shared between the 2300kv and 2600kv. Again, the only difference here is the number of turns in the windings.  The results are what really will set them apart. 

Results

Given the performance of the 2300kv RS-S I was extremely curious about this one. The 2300kv is at the time of this writing ranked as the top performing 2205 mid-KV motors, matching performance of many 2206 motors currently on the market.  The 2600kv follows that left punch with a massive right hook.  I was expecting good things from this motor but it totally blew me away. The torque this motor is capable of producing for the KV it has is nothing short of stunning.  It drives even heavier props with ease.  Based on the 2300kv results I went ahead and tested this motor on the 5x4.5x3HBN and the new Lumenier 5x5x3 ButterCutter props.  I never expected to see 1500g of thrust from a 2205 motor on a 5" prop, but as you can see this one nails it on the Lumenier, with the HBN falling only just short.  The current draw here is high as well, right at 40A for both props, but given the correct application on a light weight build to maximize unloading, the current draw should be managable. On a 500g or less build I wouldn't expect to see sustained current much over 100A in high angle of attack and sustained draw in forward flight a bit less than that.  A high end battery is definitely recommended though, preferrably graphene oxide class!  With the 28g weight and this kind of performance, I will be very curious to see what speed builds with these things will clock!
