Alternative blades

[kachur779]

compass blades seem to have a bit more flex ,i do not have a scale yet ,its the next tool on my wish list

Here's some measurements for comparison on some various sets of 350mm blades I had access to:

Warp Stock: 23.4g, 350.5mm length, 34mm chord, 4.5mm root, 4.4mm thickest part, 0.45mm at trail edge
Rotor Tech (same ones mentioned in this thread): 28.2g, 350.5mm, 34mm, 4.65mm, 4.6mm, 0.60mm
Edge 353: 33.1g, 353mm, 32.8mm, 4.65mm, 4.25mm, 0.60mm
SAB 0395R: 23.6g, 350mm, 32.5mm, 4.5mm, 4.15mm, 0.50mm
SAB (MSH41110) for stretch protos: 25.2g, 350mm, 32mm, 4.5mm, 4.4mm, 0.60mm
ALZRC FBL: 32.6g, 350.5mm, 34mm, 4.5mm, 4.4mm, 0.50mm
HK (360GFCFGWB): 27.9g, 350.5mm, 33.4mm, 4.45mm, 4.4mm, 0.60mm

Weight-wise all sets matched to within less than 0.1g except the HK blades and the RotorTech's They were flat out solid matched pairs with no detectable variance. I was impressed by that. Weights between sets of the same brand/model can vary quite a bit (a gram or more), but I thought some of you may be interested in those numbers. The Rotor Techs, Edge and ALZRC feel the stiffest, but they also have a bit more mass. The Rotor Techs, Warp and ALZRC all look like they are from the same mould. The SAB's are quite stiff too and have a shape and profile similar to the Edge blades, but the tip isn't quite as square/blunt. I personally have not flown any of them, yet. All I can do at the moment is post some numbers and tell you which ones feel good in my hands and please my eyes the most. Not much value in that so I'll just leave you with the numbers until I fly some of them. If I get bored I may measure the COG if anyone cares about that.

Thanks for that. Sounds like the Alzrc might be worth a try?
The edge I felt where as flexy as the stock blades but more weight. Bit more hang IF you they to auto. Look to fly well on my mates stretch protos.

Any length measurements? ( hole center to tip)

They were all within a couple mm of each other hole to tip, but I'll measure them when I get home tonight for accuracy's sake.

Brown santa came today:

The wingtote is a perfect fit and the side compartments should fit my charger and tx nicely. I'm going to add to the floor of the main compartment to add storage for batteries, tools, blades, etc. parallel to the boom. Brown santa also brought my Rotortech $10 dorra blades which both weighed 29.4g and are noticeably stiffer than the stock blades. I haven't flown with the stock blades to be able to make a comparison though as I haven't completely finished my build. Which leads me to brown santa gift number tres, a pitch gauge. The last step of my build. I've hovered/ piroed it in a ridiculously small area but haven't really wanted to touch the collective until I set my 13/ 12 degrees collective/ cyclic pitch. Also got a deal on some batteries which brings the total up to 6 which works out great as I have a 6 port paraboard and a 30A charger to charge them at 5a each or almost 4C for sub 20 min charges. Should be a fun weekend, wish me luck.

I edited my original post with more measurements. Just as a note the ones I listed as 350.5mm in length (which were all of the stock/RotorTech shaped ones) were just about that. Some were a little closer to 351mm than not. The Edge and SAB were dead-on though with the listed measurements.

You should start a new thread with your blade specs. Would be nice to have that info where it was easier to find/access.

radu7 - Here are your numbers just a little easier to read. Thanks for all the work.

Thank you! I just got my hands on some Lynx 350's and some Tarot 360's so I'll start a new thread like ScotY suggested and post up numbers for those as well. I'll take your lead and make them look prettier and add cost.

Anybody here wanna buy a single Rotortech from me for like $8 shipped? I had a slight boom strike on my mini Goblinesque (one blade just grazed the top of the boom cover) and took the tip off one blade but the remaining one is still in perfect working order. I really don't have a need for it now but if one if you in here has a wreck that takes out a single blade then this could well be your spare.


Gone.

To make this a more valid post I will say that the flex in this blade is probably what led to my boom strike, I'm just glad it was a boom graze instead of a full strike and I was able to land.

Hobbyking 360mm are finally back in stock.

I just received another batch of the Hk blades, but my favorite now is the Tarot 360mm carbon fiber blade at $21 dollars.My vibes became unmeasurable with these blades and performance was great, stiff blades!

Are those Tarot 360mm blades the ones that look almost identical to the stock Warp blades?

Yes they are nice. I have a pair of those, haven't been flown in 3 months but now i've 2 pairs of HK's on both Warp and tarot 480.
Bang for the buck is unreal on these
And the take light crashes very easily.
On the other day i broke on of the compass blades with a not that big tipover in a auto.
Of course those anorectic hiper light blades have to be more fragile

[Lighty]

The HK blades are crazy GOOD! For under $8 delivered how can the others compete
