for the e flight six series 2700. i think max would be around 50 amps. i run mine at around 48 on a 4 cell. its right around 725 watts or so. For props i only use the APC GAS .049 props. much stiffer. i like the 5.7x3 and the 6x4. the 6x4 is the best and around 850 watts. the 5.7x3 is 725 watts and spins at 32,000 on the ground. either of these props give the best speed and vertical. I did try the APC 5x5 electric prop at 900 watts and a 6x5.5 at 1050 watts and were slower than the GAS props. just tells me the motor cant handle it.

so for all you guys trying high pitched props i would try the above props. real cheap and i think you will like them. speed wise we are guessing around 120-125. one of the guys had a 120 bobcat or something like that with a small 8-10lbs thrust turbine lol and i was faste than him. he quickly landed.

Oh yeah i run a EVO 30 3750 4s batt and a common sense 55 amp
