One Piece Fan
I made several of these fans for myself and some good freinds I have some extra if anyone is interested please email If you would like to test out !

I designed this Fan and Have been testing it along with some other Very good Pilots(I am not good) for several months now seems to be the way to go for the guys that dont like to see anything past .001!
(I believe that this is how all fans will eventually be made!)

1. It is heat shink fit on any ys os 60 - 90 motors no extra collets or pieces
2. Predrilled for gv-1 magnets Very precise location within .0005 location evenly centered
3. One piece billit 6061 t651 Aircraft Aluminuim
4. It balances better than I ever got any other fan with out drilling to counter balance(with no work to it at all)
5. The Fan uses keyway not compression of collets so you dont have to over tighten and twist your crank(In return I believe A true running fan will help in rear bearing life )
6.typical runout is less than .001 the runout is actually not the fan but your bearings in the motor itself
7.Every fan I make is tested for runout and it is less than .0001 so if you do have run out it is usally bad bearings.
8.10 fins for increase cooling

Wow about time
I love my stratus

Please email me If you would like to test one of the last 25 I have produced

Bobby Watts showed me one of these that you did. It looks awesome. I love the idea of no dial indicating.

Wow that's beautiful, looks just like the MA ones! I'd be curious to see your milling setup...not that I have a shop but I've worked with mills and lathes and stuff at school and I find it fun to make stuff...perhaps not that complex though...or is that CNC?

Newheli,
Yes the fans are made on Brand new state of the art CNC Milling machine and cnc Lathe!

It is fun but also very time consuming I spent over 100 hours designing and devloping this fan!

This is like the 5th design till we got one that worked !

Hi mace

Sent you a PM :-)

That looks NICE.
that a very preciese hole you have made there!
That must be hard to get the toelrance in the hole for the crankaxle that exact, so that it is a "heatup - precision hole"...

Have you done any test on have good it runs (runout) if it has being mounted and "demounted" many times?

If taking of the fan, would it then not also be best to heat up the fan with a heating gun, before ulling it of with a puller (because alu get faster "bigger" when being heated up as steel, and then you do not damage the fine cranckhole) ???

Maybe it would be good to "offer" a puller for the fan (so that the hole is not bieng damage when taking of the fan)......?

I have one of the Min air fan pullers. I'm sure it will bolt right up to it. If I'm not too late will be sure to check that out. If the holes on the face where the dampeners go has the same specs (which I'm sure they are since its a direct replacement) the puller will work fine.

As I posted on the "other" heli site, have been using this fan for close to 400 flights and no problems. Have had to remove and install twice, both times the run out was practically .000. Since I have 2 Extremes, so have installed 4 times, I would say that dial indicating this fan is not necessary. ( I do it anyway,just for piece of mind).
