EDF 64mm fan Cox/Estes fan unit.

Hello all, I am agian searching for awnsers. I have a 64mm fan unit that I need to power and fly by monday. I am looking for the best low weight high power setup that can and will be used wtih a 850 mah 15c 3 cell Lithium. I am hoping that it will pull in the range of 10-14amps. Can anybody direct me to a good motor for this application. Agian I need max thrust output. thanks in advance. Take Care Chris

As far as the battery is concerned, you probably do not want to run it at that high a C value, even if the spec rates it. I haven't used that Feigo, so you may want to post specs, so guys here can compare it to motors they know of. Again, the Himax 2015-4100 seems to be a popular motor for setups that are to run 10A or less continuous. May want to compare your Feigo's specs to it.

Weight: 26.0 g (0.92 oz)
Length: 26.8 mm w/o shaft
Diameter: 19.5 mm
Output Shaft: 2.0 mm dia., 12.0 mm from faceplate
