i dont know how but i got linked to deetee enterprise and the page was a 5 blade rotor head for the 450... i was like WHAT!!! and then found they have 4 and 3 blade versions to. but they are pricey... all of them are over 350.00 plus the 200.00 mixing board. so if your serious about getting a scaled out 450 and willing to spend the cash. this is the way to go. put some white blades on there and go scale flying. they also have a nice collection of scale bodies too.

here is the 5 blade with links at the top for the others, the bodies, mixing board and videos

Looks great. I guess putting the scale look aside... You'ed get more lift maybe? How about any other performance advantages of 3 or more blades? I've seen some decent 3d stuff on video. But uncertain as to weather or not there's any real performance to be gained?

I just put the three blade head from flying-hobby.com on my #2 TRex in preparation for making it a scaler. This head is quite a bit less expensive ($100 complete) than the Deetee version, though theirs is nice in that it uses some Align parts.

You can fly a multi-blade head without a mixer or gyros, you just have to be aware that the flight characteristics are different. There really is no performance gain to be had. If 3D is what you're after, stick with a flybar head...

Neat stuff, but man I can't see spending that much on a 450 size "scale" unless you have really small fingers. I just got done with my Agusta A-109 project and while it looks cool flying around, it's not much of a scale Heli unless you are willing to spend many many hours sanding off the oversized rivets, and panel lines, making covers for the tail gear box, retracts, cockpit, etc, etc, etc. I think I'd rather do that with a .50 or larger electric conversion.

You'd never notice the extra blades when it's in the air so if you want a good flying display model, I suppose it might be worth it.

I don't think this is about noticing the extra blade while in air.
It has more to doing away with the flybar. When you fly more than two blades - from what little i know, you can do away with flybars - that makes scale models more scale like.

i saw a flybarless head for the t-rex on runryder. just 2 blades... kinda like the mikado V-Bar. and this thing was NUTS, it did every trick in the book with ease, and in the video it seemed to roll and loop faster without the flybar.

I was speaking more in terms of the 3, 4 and 5 blade heads. The extra mass will slow things down. 2 blades w/o flybar should have less inertia than a std flybar head, thus the performance, however it will be less stable.

I was speaking from a visual aspect. It's still going to look like a spinning disc no matter how many blades it has, to the naked eye that is.

Hi there

Naked eyes under sun will not see the different between 2, 3, 4, 5 or 6 bladed flybarless head. But naked eyes can see the different between flybarred and flybarless.

Under the street lamp or over camera, you can really see the different between 2 or 3 or 4 bladed head.
