Yes, you don't want to go too far forward. For high volume/low pressure applications forward curved blades will move the most air but will be the least efficient. The lepton has plenty of power to spare so I'm not too worried about cooling fan efficiency as it's a small percentage of total power anyway.

Stuka... need another test vid

The new fan is now available and will supersede the old design. The new design is a little more effective at cooling than the old design. See Finless' old/new comparison test vid HERE. Thanks again Bob

The price will remain $14 shipped in the USA (add $1 for international shipping) and includes qty. 3 M2.6 cap screws. Here are a drawing and a photo of the new fan:

So how do we go about ordering one?

Finless · 11-27-2006, 09:47 PM

I am pretty sure if you PM him you can work out how to order one. So you know this fan is a BIG help on reducing the temps on a Hyperion 3025 motor! After doing the vid for him I have flown several times HARD and man the motor will love you for having a fan

N1troyboy did back to back testes on the MK1 fan here in Sydney,
15 to 20 degrees cooler with Stuka's fan, great work Stuka!

Finless · 11-28-2006, 03:56 AM

Hehehhe glad to see someone else backing up my tests. Personally this fan is worth it and I would NOT run a Hyperion motor without this fan!

Thanks!

Bob

hung · 11-28-2006, 04:13 PM

yep the fan is well worth it
Nitroboy's motor was 20 degrees cooler with the fan

CRAZYKEV · 11-28-2006, 08:59 PM

PM's ya' Stuka :mrgreen:

CRAZYKEV · 12-08-2006, 12:11 PM

Got my fan today Stuka. Thanks bro! :mrgreen: :mrgreen:

Ace Dude · 12-20-2006, 10:15 PM

How's this fan compare with the stock fan on the 3025-10?

dsrj · 12-21-2006, 09:40 AM

Hi Stuka,
Just to let you know i got my fan 2days ago.
Have a Merry Christmas,
Thanks,

Unless Hyperion added a fan, they dont come with one stock!

The fan Stuka makes is going to be better than any other fan out there. Reason being is that the Stuka fan in uni-directional and the Hacker and Hyperion fans are bi-directional. We know what direction the motor needs to spin so he optimized the fan to work in that direction. The other fans have to work in both directions.

Jafa · 12-21-2006, 02:14 PM

Hyperion do have a fan on the latest batch of the 3025 motors
It looks very very similar to Suka's fan - I'm sure uni-directional also
The Hyperion fan is made out of metal - it's very thin/light

Got my "Stuka Fan" this week.

What a wonderful piece of machining!

Stuka was kind enough to mirror the part to suit my backwards spinning 3DX layout.

Hopefully get too see how much cooling effect it has this weekend.

I agree with you to that aussiemick, just got mine today and it is really an amazing piece of work. I compared stuka's fan with the original fan that came with my hyperion and it has more blades. How did yours go!

aussiemick · 10-18-2007, 12:47 AM

I haven't had the oppurtunity to measure temps but I can now leave my fingers on the motor for about 5 seconds maybe a bit longer. It used to be maybe a second at best.
