Hi: Frank
In the F-14, I run Two 120mm ChanSung EDF units. ( 12 Lbs of thrust each)
The F-14 Ready to fly is 36 LBS
I run two 6 cell 6000mah 100C lipo packs per fan unit. a total of 4 battery packs.
Each fan unit will give me 12 LBS each.
I have a 3 cell 2200 lipo pack for the RX.
I also us a 2 cell 2200 Lipo pack for the Old Heavy Yellow Aircraft Wing swing Servo.
The photo will show the fan unit set up info.
Thanks
Wayne
