Any blade that fits the airframe.

If you have a 550E, these are the blades:

Align HD520DT

The Trex 700 / 800 3-bladed head conversion will take any blade between 690 and 800 - depending on the airframe.
I fly my 700 3-blade using 690.

I am going to buy two of these for my 600E Pro and 600N Pro.
I will fly both of them with 600mm blades.

This is for a 600.

Although it will fit, it is not optimal to use blades meant for a 2-blade setup. Weight, CG is different and also consider disk-load of 3 vs 2.

If you cannot find a bespoke 3-blade set in 600, best to match a set of 550 / 560.

Look at the specs of the 2 vs 3-blade sets from SAB, Zeal, Rotortech etc. This will give you an idea of what they change from 2 to 3.

Zeal has a 3-blade set of 550mm Energy CF.

The reality it that as long as the blades match in weight and span wise CG, they are fine.

The Align and the Zeal 3-pack of blades for the 700 (690mm) are identical to the 2-pack for blades for the 700 - except there is an "extra blade".
Granted, someone took the time to make sure they all matched, but other than that, they are the same.

I fly the 700 3 blade head with 3 690mm Zeal Energy CF blades.
But, I could fly it with 710mm if I wanted too.
I also have the 3 bladed tailrotor hub and I use 105mm tail blades

Funny thing: My 700 3 blade is on my Trex 700 Nitro - not a 700E. It flies with a YS 120SR-X and does quite well @ 1950 RPM headspeed.

I have asked Zeal if they will sell me a 3-pack of 600mm blades for my 600 3-bladed head.
I will try those on my 600 Nitro first (with the new 550 / 600 3 bladed tailrotor using 95mm tail blades) with the YS 60SR and see how that goes. If needed, I can try the 550mm blades later.

But, I would be willing to bet USD that the 3 bladed head would be smoking hot on my Trex 600E Pro with the Scorpion HKIII-4035-520KV and 3 600mm blades. I fly that @ 2200 RPM headspeed and it is a blast on 2 bladed.

As a side note:
I converted my SAB Goblin 380 from 2 blades to 3 blades using the SAB conversion kit. That kit includes the 3 SAB blades.
They are identical to the 2 SAB blades that were originally included in the 2 bladed kit.

I imagine Align will get a 3 pack of 600's out soon, but if Zeal beats'em to it, I'll try theres. I would think that the Align 90mm tail blade 3 pack for the 550 will be fine on the tail.

Zeal has these blades at 550mm. I think I want them a bit longer, but they might work well. They will out weight the 2 blade Aligns by 78g.

Material: Carbon Fiber
Length: 550mm
Chord width: 50mm
Root thickness: 10mm
Hole Diameter (Bolt): 4mm
Weight: approx 116g (single blade)

I sent email to Zeal about a 3-blade pack of Energy CF 600mm
They said no problems.

They will charge $127.50 for the set and you pick the color.

I order the 550 Zeals so we should compare our results. I think that a shorter blade should be better than stock 600mm blades unless we all change to the 800mx motors. Maybe I should put my 800mx in the 600 and upgrade my 700 to an 850?

I really can't wait to give this new sh@t a try. A new frontier for my favorite Align 600 size.

I flew my 600N on the JR 3 bladed head and blades for a while as you can see in my profile picture. It is really good and the YS60SR hold if pretty well. You only have to be careful on the max pitch for both collective and cyclic and you will be fine... I was using 1950 to 2050 RPM... Super stable and super fast at the same time.

I don't like the fact that the blade and heli manufacturers do not pay attention to the 3 bladed segment designing dedicated blades. The use of the normal blades on the 3 bladed set makes it too draggy at high pitch and you can really see that on the end of an autorotation when the RPM falls really fast. It would be good to have a set o higher aspect ratio blades (smaller chord) on the 3 bladed heads... but the choices are limited now.. specially on the 600 size. For crazy power 3D flight this is not an issue anyway...

I think you will enjoy it anyway.

Cheers

Marco
