The EfliteSix Series2700 k/v is a good motor. I have had one for over a year now in a Stryker. I was running a 6 x 4, 7 X5, and then moved to a Graupner 5.5 x 4.3 Speed cam prop. Its a very durable motor, I do not have heat sink on this one. I wouldput heat sink on it thoughif I were you.I have ran it hard some hot to touch -WOT nearly 80% of flights. I have well over 200 flights on this motor. I put that prop onso it would cavitate, on purpose.That on aStryker combined with rudders and airbrakes makes an excellent Stryker for inverted hover on a 3S 2200 mah lipo.
I attached Eagle Tree readings of a Eflite 6 Series 3S2200mah 30C Outrage XP lipo, BP Industries 60amp ESC, and Graupner Speed cam 5.5 x 4.3 prop.

.....Iactually use the same BP Industries 60 amp ESC on my Mega 16-25-3, 6S 2200mah 35C Hyperion, with an APC6.5 x 6.5 Pylon prop... it runs cool no blitzing the ESc either.
