I ordered a cf boom for my 500 and it appears to be aluminum covered in cf ? Anyone have knowledge of this ?

If you're not living on the edge you're just taking up space !

Yeah - those are the genuine Align CF Booms. Knock offs are CF only, which tail belt people seem to like if they fly in extreme cold.

I believe Align 450 CF booms are CF only, so who really knows what difference it makes?

Well the hybrids booms that align are only for looks. Nothing else. The 450 size boom align makes is a pure CF and i highly recommend it. On 450 size they don't break easily. They did make a 600 size right before they came out with the hybrids booms, but they stoped. I know one reason they stopped. It was super had to push the rubber grommet for TT thru a CF boom. But personal i seen a huge advantage in Pure CF booms . In crash on a larger heli like 600 + it shatters. So your TT and Tail gears would be saved. Now on hybrids they bend like metals ones, and love to slip out heil. So i don't think they are worth the extra $$ unless its for show.

Its metal boom rapped in CF , ya I personal would not call it a CF boom. But they look nice. Also the 250 CF boom is 100% CF.

If anything, I'd have to say the hybrids are stronger - not weaker. Something's gonna give in a crash. FWI, the 500 boom I tried that was CF was noticably weaker. Unless you want them weaker?

I have to give your creativity points for thinking the reason they changed was grommets.

The aftermarket booms from HeliDirect I'm pretty sure are CF only. They're almost half the price of the Aligns.

CF is 5x stronger the steel and 2x more stiff per volume but more brittle.

They're weaker, not stronger. Must be the two materials working together that make the hybrids stronger. Just reporting my findings. So you want them stronger or weaker?

If you can't dazzle them with brilliance, baffle them with BS.
