At least I can see that it flies... in reasonably stock form there.

No cheater(s) on this as it came though.
The inlet area is quite a lot larger than the exhaust area. I would guesstimate 1.3x or so.

ordered the new housing that RClander did for the CS12 fan.
going to be running and checking the blades every time..
thank god I got an antirioting shield..

I tend to believe with all the research I'm doing that the rotor is getting weakened use by use.
maybe the material is getting softer.

Here the high temps of 40 degrees celcius and above help that to happen earlier..
but when it eventually fails I think the RClander hub with the stumax rotor (that Stu will be selling for around 160 bucks-rotor only) will be THE winner from now on.

Pav, I've ran the CS10s in lander shrouds and the static thrust was down over a pound.

Either there's not enough stators or the stators present don't have the same degree of bend in them

Just received a new "fan only" from HK with very interesting results!
The new fan (minus adapter, spinner and screw) weighs 51.6g.
I have two fans from previous HK orders (that came complete with shrouds) and they weigh
45.3g and 45.0g! The new fan blades are noticeably stiffer than the two lighter fans, and the remnants of my recent fans that failed.
Changesun has changed the plastic density as the new fan weighs approximately 10% more.
HK never acknowledged that my fan failures were part of a substandard batch of fans, but it seems that CS has made some changes.
Cheers Eric

Exactly my conclusions when i compared the xflight and the hk fqns.
Buuut scott sent me another fan that i should he getting tomorrow or on monday so i will see if its one of the better quality. Whatever the xase is i will have a stumax rotor in 2 weeks and i wilk run both the stu and the cs12 in the sane rcoader new multistator housing.
I will have some numbers then...

More blades more turbulence more stators needed.. The new rclander housing made for hk has 11 stators so i expect that it should work better.. Only tests will show though. Now that stu will be selking the rotor only we need to find a good housing for it.
Let the games begin

Btw i also have a cs10 fan. I want to run it in an het and stock housing so i tried to bapqnce it today to realiaed that it needed no balancing at all. :O

Same experience on the last two and the 4mm adapter was tight and had places for 4 grub screws

Interesting theory...go count the number of stators on your 11 blade stumax fan and let us know, my last count was 5...

Still waiting on your name or order number, no amount of avoidance is going to work Pavcon, you made slanderous remarks about my business that appear to be based on a lie.

That is a longer shroud smartie that counters that. Qs i said.. Tests will show...
I was never absolute about that matter
But if tim wan says it helps.. He sure done his homework...
