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

Would this be a good choice?? Feigao 1308422S Brushless Motor 22 Turn, 2.0mm

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.

The himax has too big of a diameter can. no good to me..... thanks agian for the info. Chris

try razor. it fits inside the cox estes fan shroud.

thanks IGO. How about the Razor RZ-Heli?? that is the only motor I have found that they can ship and have to me by tomarrow.

The Razor Micro-Heli v.2 Brushless Motor is designed for the small helicopters such as the CP Hornet. Calculations show that its efficiency is 80% at 2.2A @ 11.1 V and 87% at 7.7A @11.1 V. Use 10 tooth pinion for CP Hornet Micro Helicopter.

Kv: 4300 rpm/v
Io: 0.45 A
Rm: 0.120 Ohm
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
Bolt Pattern: 2.5 mm mounting holes on 1 16.0 mm bolt circle/ 2.0 mm mounting holes for the 19.0 mm Maxon Gearbox

Thanks guys I ordered the Micro Heli motor. Later Chris
