I believe it's a 5 blade fan, if my habu is actually containing the e-flight edf delta-v15 3200 motor fan combo.(pretty sure it is...) Seems to be pretty durable and pretty good thrust for price. So unless your going for hogwild power, it works great. What ya' got planned?

The rotor has 5-blades. You can buy spares [link=http://www.horizonhobby.com/Products/Default.aspx?ProdID=EFLDF151]here[/link].

RE: # Blades on EFlite Delta-V 15?
My Christmas will be without a kit. My new years resolution is to build a sapac viper jet. 70mm. I'm trying combinations to get 1400 watts and keep it efficient. Not too many motors can withstand that power. The rotor has to be safe to 56,000 and the batteries have to pump out current and sustain at least 6 minutes. 5 cell pack for instance. 21 volts. (18.5) is 67 amps. 6 minutes is 1/10 hour, so at 67 amps the battery would be 6.7 amp/hour. Tall order to get 1400 watts to run very long. and tall order to fit 2 5 cell 3300mah batteries. 4 cell is a worse scenario. 6 cells is 25.2 volts. 55 amps. a 5000mah 6 cell is viable. So 56,000 rpm divided by 25.2 is a 2222kv motor. I'm looking for a 2200 or down to a 1900. on 6 cells. Or my 2600 on 5 cells. I've got to find a motor that is 2600 or 1900 that can stand 1400 watts. Probably Hoffman magnetics outrunner, or Castle Neu inrunner.
