I have 2 6s 2650 40-50c zippy flightmax packs on 2 of these, running 62 amps, @ 20.16 volts for barely over 1200 watts per fan. Seems like the battery needs to be a nano-tech to hold a higher voltage. The timing was on auto, then on 22 degree to 30 degree high timing and both readings were 62~63 amps.
Only getting 1/2 the thrust on my F-18...2.8 kg total for both units. Plane is 3.9 kg
The Turnigy 2700 mah 6s 65-130c packs are on my shopping list.VERY NICE!!! 7S 5000ma 35C Nano-Tech, Birdie 180 ESC and this EDF in a Falcon 25. Flying weight 7.2 lbs (heavy)... Goes ballistic vertical...Exceptional Value, my unit was very well balanced, came with a Y-lead. 2.9 kg of thrust, settled around~82A and 2100 watts of power. Inlet ring can be screwed off just like any other high end unit. This is going on a 70mm Viper Jet from HK.I put this in a dynamo Meteor 70mm. I have never had a fan that is so well balanced! It is silky smooth and fast! Sounds Like a real jet during a 130mph low pass. :) I get 4 min of fast passes with a 4000 mah 6s using around 3,300 mah. If I fly it around 100 mph it is around 6 min flight time. Best EDF setup I have ever had!
