Mystery - Are the Align "Carbon" blades really carbon??

Got my Align "Carbon" blades yesterday. It's a puzzle to me because they look like plastic that has been spray painted black. Once someone destroys one of these new blades, maybe we will find out what they are really made from. They also have the usual lightening holes like the wood blades from Align and this is something you don't see in CF blades as it takes a way a lot of the strength of the fiber weave pattern. Notice Align didn't use the words "Carbon Fiber" on these or any catalog postings. I suspect all the carbon may be in the paint ????? They are much stiffer than the 335mm woodies so they will serve a purpose, but they are not CF blades like ModelSport and SAB sell for sure. I'll be interested to see what others think about these "Carbon" blades. This might explain why they are so cheap when compared to CF blades.

If you look on the Align website, it says they are injection molded carbon...i.e. something similar to a plastic glow helicopter's frame material...plastic with fine fibers of carbon (not a weave) mixed in with the material.

Once I saw mention of this, I realized why they are much less expensive than the typical carbon fiber helicopter blades you see out there. The typical carbon blades are, essentially, hand made = high labor costs. The Align carbon blades are mass produced, hence the lower cost. Actually, considering how they're made, they should be only slightly higher in price compared to the stock plastic blades included in the kit! So they're actually very expensive!!!

yeah, they are carbon injected, but they seem like a decent deal considering your other options, they are much more rigid than the abs plastic and wooden blades and at $20 I think they fill a nice category between wood and real carbon fiber.

Yes, I agree...IF they work well. The material a blade is made from is not important. What is important is if it's rigid enough (in both the spanwise direction and in torsion) and how it's balanced (total weight, spanwise CG AND chordwise CG).

How well to they fly? I have been trying to find some...no luck so far.

I've had appx. six flights with my align cf blades on my stock(non-stretch) T-REX, flys great, good TR clearence, I've had several boom strikes with aligns 335 wood blades, I think the woodies have too much flex and are prone to boom strike.

Hello,

What kind of flying are you doing? Curious to know, for reference re. the performance of the Align carbon blades.

When were you seeing boom strikes with the 335mm wood blades? In flight boom strikes?

Mission Success!

Boyd -

To resolve this issue once and for all, I decided to do a science experiment to get to the bottom of this. It would take an accurate flight path for sure -I decided on a 20 degree descending approach, with a simultanious banking angle of about 80 degrees (blades almost vertical). This would ensure the best chance of a decent blade-to-ground contact at impact. Execution was perfect, and the results - well, this mission would have exceeded even the mars rovers success - not only did I snap and destroy the blades in multiple places - I even totalled the helicopter! What more could you ask for. The only unanticipated hiccup was that the broken blades dispersed widely into the long grass. A quick search soon retrieved the pieces, and I am now happy to report, that, on close examination, indeed there does appear to be evidence inside of round, blueberry-like carbon spheres. No wait - that's a severed round carbon rod going down the middle there. It also appears to have additional carbon in the leading and trailing edges, although some of it is hard to discern from the plastic moulding. I have now applied for additional funding from "headquarters" to continue this type of valuable research.

-Jonathan.

Hey guys... I'm an R&D chemist. If you want to know what's inside of them... send me a sample of a broken blade. (PM me for an address) I'll run thermal on the plastic, and do a burn off on what is left. If there is carbon in it... I'll find it. I can also run an IR on it to see what kind of plastic they are using.

Just an offer.
