Do these make a huge difference in performance compared to the stock FG fan? I have found that the fin in my heli has what seems like a non gyro related virbation... I reckon it could be engine/fan related. I am considering an upgrade to a metal fan to see if that goes away. ANy suggestions?

cheers

For a while the plastic fans seemed made out of butter and it was almost mandatory, now its nice to have but I dont know about mandatory.

As for performance I'll bet they blow the same amount of air. Aligning the engine and dial indicating the fan and clutch would probably do more for vibration than just a metal fan.

I got my kit last June and have been running the plastic fan since. No problems thus far.

The original plastic fans required upgrading.

I think the new ones are fine.

You can replace it, but there is no bling factor. No one can see it, and only you will know.

On the other hand stop making excuse and but the fan, NOW.

I remember finding a link where a guy tested a number of fans, plastic, a couple different metal ones etc.

The metal ones where better cooling wise compared to the plastic... but again it may have been a while ago before they updated the plastic fan.

I have a metal fan on my 600. I suppose the only real benefit now is that I don't have to worry about it anymore.

It's a complex, costly, glow powered anti-gravity machine!

Twice I've had the Align metal fans (with two magnets installed) fail... so bad that it literally blows apart like shrapnel and out the shroud. It's not cool when that happens (no pun intended) because your if you don't chop the throttle right away and auto to the ground you can fry your engine quick.

This is all given I am a hard 3D pilot, so I have allot of fast changing movement that may cause extra stress on the fan's gyroscopic spinning force, causing flexing and ultimately metal fatigue.

I'm currently running the QuickUK fan and not having an issue so far (about 50 flights). I've not attempted to balance the two previously failed Align metal fans, but this current QuickUK fan I did balance on a magnetic balancer while attached to the aluminum hub with four screws.

Like I said: so far so good. I'm wiling to try the alleged new plastic fan and see if I still sling magnets.

The metal fan will absord the heat from the engine and disipate it better than a plastic fan ,however, I cant tell you in percentage how much more heat is taken away with a metal fan to justify the change to a metal fan.

Going by that, I think it is a good move to replace it with a metal fan, I have not had a problem with it since day 1.

in the summer a high output fan will help when its really hot out. All depends on where your flying I guess. Here is the link for the fan reviews.
