hi, I have a top Flite EDF hawk. I bought the version with fan only as I had the motor and ESC from my written off Phase 3 Fantom. I've put the model together and everything seems to fit ok. I fly off tarmac so expected to be able to ROG easily but when it came to the maiden flight the wasn't enough power to lift the aircraft. I tried changing the battery incase I was using a duff one but the problem remained.

Is the motor from the Fantom not powerful enough?
Does anybody have any suggestions or thoughts on the lack of power?

Any help would be much appreciated.

Thank you.

Apparantly it is not

from memory the Fantom EDF is a Hi KV motor with 3 blades,
its unlikely that the motor will power any other EDF with a different blade count and pitch,
also the Hawk is not as aerodynamic as the Fantom so its gonna struggle to make it fly correctly,
also the Fantom EDF is a direct intake and the hawk has an inlet chamber that will also reduce the thrust,
i would check the amps your pulling on your setup and a possible way is to up the cell count for more OOooMMPPHH

OK, so how many watts will I need to power the Hawk?

Just so that I have this right (I'm fairly new to this stuff) watts are volts x amps?

Does it mean I need a different motor?

if you are new to electric and EDF i would use the recommended set up,
this will make it fly,

Dont expect mind Blowing Speed from it,
the link below is to a Vid at Longhorsely LMA and the Hawk had 630 watts running on 4S and it still couldnt out run my Vulcan using 158 watts on 2S [8D]
