I am searching for a 96mm EDF setup for Nitroplanes Eagle Hero. I found the Himax 96mm edf unit (assembled) for $150 each but it seems a bit weak for this airplane that will weigh around 17 lb. Himax 96mm EDF with 1850kv brushless motor 2600g thrust - V2 UPD
NEW 96mm EDF with stronger motors (Ver. 2).
• RTR high power ducted fan with factory installed motor.
• All feature high quality Himax brushless motor.
• Dynamically balanced.
Can anyone suggest a good combo fan + motor for 6S lipo that would not cost a fortune?
Philbel I have this kit but wont start the build for a while. I have researched lots of 90mm set-ups for it. It came with 100mm fans. You get a lot more thrust out of 100mm than 90mm but you can still get what you need from 90mm. Target around 7lbs per fan for high performance. You will not have ducting loss and the fan will of course have an intake lip so the power will not be hard to find. High blade count fans will eat a little more power for the same thrust than low blade counts but they will sound better. So if jet sound is important than maybe a JetFan 90 or the Lander 12 blade. If sound is not important to you than the Wemotec 90mm is pretty tough to beat. I prefer volts over amps for the same given power level so I am planing 8 or 10s. Either way even with 6s you should be around 2200 watts per unit and in most fans that will get you to 7lbs thrust.

I think its pretty easy to get more than enough power for this model, even on 6-8s. As its a twin, you will likely get the beat effect sound anyway so you may not be too worried about trying to work with the cheaper chinese multi blade rotors.
My suggestion would be either wemo Midifan with HET 650-68-1600Kv or Jetfan 90 running HET 700-68-1500Kv, both on 8 cells.
The Wemo combo pushes 4.2kg thrust on the test stand with inlet lip at 2730 watts on 8 cells. The Jetfan pushes around 3.7kg at 2470 watts on 8 cells.
You an get the Jetfan up into the 4.2-4.3kg thrust mark by going to the 700-68-1680Kv motor but power is climbing up around 3100w on 8 cells.
I am running a 6s Jetfan in my latest Mirage in one of my Alloy housings, its pushing around 3.5kg thrust at 2350 watts or so, even this would be more than enough at 15+lb for 2 fans.
As for losing bench test power when installing into a model, you are building something with pods, no intake ducts just nice curved lips, and short exhausts, you should not lose very much if anything.
