I got 2 fans for the 737 and 2 extra for....hmmm, lots of ideas . I placed my order Jan. 19th, it shipped Hong Kong post office on Jan 20th and arrived (Florida, USA) Feb 4th, so that's about 2 weeks which I am very happy considering Chinese New Year was in the middle of that.

Since I am relatively new to ducted fans, I am trying to get exact detailed information of how all the parts go together - like what fits with what. So I will try to post some detailed photos of what I discover about these fans as I go along. Here is my first go 'round. I have not ordered any motors yet, so please realize the last photo is just the fan sitting loose in the shroud, so if it looks like the blades are touching the shroud, that's why.

I took a whole bunch of exposures and selected the best ones which show the detail.
im gonna be using some of those in my 777 whats the quality like ?

Rudder/Nose Gear Steering (2 servos)
Elevator (2 servos)
Flaps (One channel, two settings, servo delays for speed control) (4 servos)
Spoilers (4 servos)
Retracts (3 servo-less retracts)

Lights are off a battery lead (no RX channel used)

I so love my 737, what a sweet airplane. I forgot how "big" it is, and how fast. Latest Youtube to follow this week...

And, though I landed slightly faster than I prefer, I finally greased it Sergey style.
As a follow up, here are my two flight videos from the weekend...

Well today my HET6904 fans arrived today and here is my question:
After having made room for my Hyperion motor and I mounted in the center as much as possible, then I fired the fan up with very little throttle and the fan started to scrape the inside of the housing. I stopped it immediately and took a piece of sandpaper and started to polish the inside and fired it up again and this time it sounded a lot better.

Can this really be true? Do all of you guys have scrapes on your housings?

I based my decision on all the info in this thread Change Sun 10 Blade 70mm. I have read through most of it and seems to be working just fine for lots of guys pushing it way harder than will be needed by this 737.

My main reason for wanting the 10 blade fan is to get closer to a turbine sound. Many other fans work just fine, but I'm after the sound. I posted some detailed photos of the CS 10 blade fan here.

I will post my results, but I won't have time to make my final motor selection and order until this weekend.
