Anyone use this new one yet? I heard the older ali ones were troublesome. I just did my annual cold weather break of my stock Hawk fan and am thinking of upgrading. At $5 per year is isn't that bad and plus it makes me take a good look at the mechanics of my bird and peek at the Bearings while I'm in there. Just wondering if this is a better design.

Well I can say this for it, It has a place to get a wrench on it now so I can stop rounding of the top trying to get it off.

What is the deal with the stock plastic Hawk Fans? I have broken one at least once each year. Is there any way to upgrade to something that doesn't shatter after a few dozen starts?

the trick to NOT braking a "Cold" Plastic Fan,, is,,
NOTE> with good Batteries your Starter turns faster than your Engine idles,,

so as soon as your Engine starts remove your Finger from the Starter's Button, then let the speed of the Shaft decrease to the same Speed your Engine is Idling at before you lift-out the T from the Fan,,

I have not broken a Century Plastic Fan in some 7 years using this method !!!!

Bloody Hell. There is always a trick somewhere. I've never been fortunate enough to go seven years (more like seven months) without cracking a fan. Good tip. Thanks Jim.

Hey guy's. So I want to upgrade my fan to have more flow to my Toki. So if I get this fan, I need the wand and that's it right? I need more information on this which not much information online. Thanks.

I had this fan on the Raven 50 and then the NX50. It is a good fan. But you do need the special shaft for it. The shaft needs a round 6mm end on it to be inserted into the one way bearing.

In terms of performance I never really paid attention to the cooling effect, so i cannot comment on that.

Yea I was right. I have a friend that he is a fan of Century for many years. But I told him that there is a new fan that replace the upgrade fan that is on the Hawk pro upgrade section. Install fan remove the hex adapter and shaft plus ball bearing shaft and start from that wand you showed me. Thank you.

By the way I know it's not that new been out for couple years but it's new for him. LOL

Another option if you do not want to get a different shaft is to get the plastic fan from the NX50. It has a built in hex adapter in the fan itself. If your starter has a one way built onto it, then you can use the same hex shaft as any other heli and not need to switch to the round shaft.

It is hard to tell without measuring. I never noticed any difference.

I'm talking about nx50 will it blow more air then hawk pro fan they both are fan. For sure yes the metal fan will cool down alot more good for having the toki tune a bit leaner with upgraded fan for more performance ofcourse it shorten the life.

plastic fan or metal wont make a difference. It is the design of the fins.

I had the stock plastic then the metal fan on the NX50 I had. I did not notice any difference. If there was a difference, it is not significant.

You don't feel the different. It doesn't make you're heli react different. WHat you will know the different if you check the temp it should be a bit lower on temp. Did you check if you're engine is running cooler? Lower the temp the higher u can lean it. I don't want to lean it out but to where it is safe.

I'm talking about the cnc.

Please read my last two posts.

I never measured anything, and no noticeable difference in power.

Dont think more air flow = more cooling = more power. It is not that simple. When the trex600 first came out aftermarket fans were coming out everywhere for it. Some worked better then others. Some worked TOO well in some regards.

If you are moving too much air then you lose power just turning the fan.

If your goal in the metal fan is to get more performance, i would not waste the time or money. I did it partly for the "Bling" and because I liked the starting method better.

Yes that is true. Metal fan does weigh a bit. Very true. But I believe there is more airflow due to those curve. But making it metal and plus curve is pointless. Good upgrade for looks and plus get's rid of that starting shaft with spring. Some people tend to break the top part of plastic fan. My friends never broke the top part of the fan that the tbone meet when starting. I how ever would like to put a lot of cnc parts on y helicopter including flybarless head. Hawk pro is a very good size helicopter.
