Question Blade research, 8 brands, what's best...

Hello Heli Freaks,

I have been hearing a lot of questions about blades, so I have taken it upon myself to do a little research on them, and to post my findings…. This will be a running review and I look forward to finding out what the “Best Blades’ are!

Now that being said the results will be the best blades for me, I want to try to keep my research objective, so I am going to try different things to test the blades. Right now I have done some weights and measures to get the bottom line on 6 sets of blades. In the future there will be more but for now these six will be the base line for the testing!

I have

Thunder Power 325s
SAB 320s
Align 325Ds
Sonix 325s ( Heli Direct brand and the cheapest)
Radix 325s
Maverikk G5 325s


To start the review I got out my ruler, blade balance, and calipers, plus the old digital scale…






As it turns out different manufactures have different ways to measure the length of their blades.





I set the bolt hole to 325 and then looked at the blade tip at the trailing edge of the blade...





Hmmm. they are not all 325? In fact only 2 come close and they are the Thunder Power and the Maverikk.


So I took two measurements, total blade length, and blade length from the center of the mounting hole.


Total Blade length

Thunder Power 337mm
G5 336mm
SAB 331mm
Align 325mm
Sonix 326mm
Radix 325mm

From the bolt hole...

Thunder Power 326mm
G5 325mm
SAB 319mm
Align 315mm
Sonix 315mm
Radix 314mm

Next I put the blades on the balance and checked for the length ways CG.





Then I took measurements of the distance from the center of the bolt hole to the CG of the blade.

Thunder Power 171mm
G5 164mm
SAB 168mm
Align 166mm
Sonix 169mm
Radix 156mm

Next I put the blades on the scale and looked at the blades weight.




Thunder Power 22g
G5 31.7g
SAB 20.3g
Align 19.8g
Sonix 20.1g
Radix 21.8g

Since I have had loads of blades through the years I know that blade weight can vary from set to set from the same manufacture, 5 Grams +- is pretty normal...

The last thing I looked at was the blade thickness at the leading edge

Thunder Power 4.22mm
G5 5.1mm
SAB 5.2mm
Align 4.05mm
Sonix 4.15mm
Radix 4.06mm

Well looking at the results from the Facts, and these will be the only facts here, since every review is subject t the bias of the reviewer! I can draw a few conclusions

But I wonder what you Heli freaks would gather from these weights and measures?

I come into this review with a favorite, but there are some new blades here for me to try. If you have seen any of my other post on this topic you'll know I like the Thunder Power blades!

I run the "SONIX 325's" Also ...

I HEAR they are just now starting to become very popular much to a certain
Helifreakers chagrin, who him being that was HFG{HaHa}

Fly GOOD, can't say they fly GREAT because I can't fly GREAT but I can
say they are easily DONE IN as the second pic shows. That was my second
set, I'm on my third although my first where in worse shape but I have no photos
of that mishap .... It's hard to quantify but the HITs where not that hard IMO...
I know my ALIGN w00dies would have survived is about all I can say... STILL
I do like the SONIX's allot and will continue with them hoping to grow into them
being the planed idea.

w00d

Default Test helis

Sticky status... Cool

Well wOOd, I know that CF blades suffer a different way than the old woodies do... I just have the one set, I have used "Sonix" stuff on other parts of my heli, and they make pretty nice stuff for cheep!

On with the test results...

I have 2 450s I plan to fly the blades on to make my judgment of which one is the best!

Heli #1 is my tried and true old V1!



Heli #2 is my new freshness 450 Pro



In the name of trying to be subjective I will fly the same 4 batteries through the testing, I have 2 Turnigy 30C 2200, and 2 30C Flightmax 2200s, in the end I will fly all the blades with some 40C and 45C packs, as some blades are better suited to higher RPMs.

Next certain blades work better with different head setups, so results will vary among those of us who use lighter faster paddles or different length flybar rods, I'll be using Align CF paddles, with a 2.5g weight on the pro, and stock plastic on the V1, both helis have 220mm flybars.

This morning I had a chance to fly all 6 sets of blades in the driveway, so I have a very basic impression of how they are working.

Here are my preliminary findings...

The SAB blades don't fit well in the pro grips, they are a little too long, inside the bolt hole, mods will be necessary to get them just right! ie; able to fold into the blade holder...

All the blades would track either straight away, or if they were out of track, I flipped them grip to grip and then they were spot on...

Yes, Capi... the Sonix are the best deal in CF blades that I have found. No Cap, I won't subject you to the horrendous task of flying them all by yourself, I must help you!

As chance would have it, I have procured a 450SE V2 to help with the testing. A friend bought one a while back from another friend. He has a sick father and has not had much chance to fly it, so I asked if I could use it for this test, he said what's mine is yours! Cool, this heli is a bit of a power house, it has the 2221-6V2 motor and last time I saw it it had the old style Align CF Blades, so we can add one more to the mix!

hehe my Fly-Bar Cage and Swash both are made by SONIX... One time my entire Head was made by them... But at any rate yeah there's no doubt I really like their blades.... I prefer flying the Sonix's and given they are cheap enough I also have NO issues running them as a n00b over those same w00ds.

I went thro about 10-15 pairs of blades this summer on the 450..... these blades have made it affordable.

Top work, thanks for posting that reveiw. Deserves sticky status.

The differences are amazing, especially the weights!

Thunder Power 171mm

Align 166mm
Sonix 169mm

Hello Freaks,

Sorry been neglecting this thread a bit as of late, bad weather, a fun fly, and the holidays?

So I tried the 3D Pro blades on my V1, fitment and looks are up to par, I have only flown them a couple of times and have not tried them on the other two helis. They track pretty well, they seem quite stiff but I was a bit surprised that they seem slower than most on roll and flip, I'll need to do more flying and try them on the other two helis to be sure, the last blades I had flown on the V1 before these blades were the sonix. so my first impression is these will make good CF blades for people who are just starting to fly CF, they are more stable but still flip better that woodies, and will be ok for higher HS than woodies. I did see a few threads that had negative comments about these blades, but they seem OK to me? I'll look for the threads and post a link if I can find them?

snjBird! Sorry if you already mentioned this, but what head speeds are you running on the three helis. Specifically the head speeds you used with the Sonic 325 blades. They are what I use and I want to step up the pinion for some more power. I am only using a 12 tooth on an Align 3700Kv SP and Align 35 ESC. I havent Tached the speed but the HS Calc. says just under 3000 avg. HS. Could you let me know.

Thanks. Michael

I like 3300-3500 I have only been doing the HS calculations, never tacked the head. I have the 430XL 3700KV with a 13T, and the Pro motor 450M with the 14T, and a Scorpion 2221-8 3595KV with a 14T. The Scorpion will give a little higher HS than the others, but they all average 3300ish. The heli I borrowed from a friend has the -6 scorpion and it is even faster on an 11T, but I need to do more work to integrate that heli into the testing, it has gyro issues... All three have the Align ESC

Thanks for the reply. I think for the moment I will step up to a 13 tooth and I will get the 14 for the days I really want to get a crazy HS. I just dont seem to have the pop and stopping power that I want with the 12 tooth.

It seems fairly easy to bog the motor on this setup. Will increasing the HS help with this issue??? Sorry to post this here. It was just a follow up to my original reply.

In theory, a larger pinion gives the motor less leverage, so it will be easier to bog... On your motor I like to stick with a 13T, it seems to be the best for my style of flying?

Yes the 325Ds are great blades, they are fast crisp and precise, they work well on the Pro and the V1, one of the better blades to be sure.

Well the holidays are past and I can get back to some serious heli flying and research! I have a bunch of these blades that I have crashed, would you Freaks be interested in seeing the inside of them? "Read I got a new Dremil for Christmas"

Go for it! Cross sections of each blade would be great.
