450 carbon fiber boom or metal
Is it a cheap way to make it your self?
Or is not worth the effort?
What about the metal ones?

Thanks

Carbon you could but I highly doubt it's worth the effort.

If you are looking for mega cheap, maybe check flea bay for 450 clone booms.

I been buying from ebay and some are good and some are really thin.
I knew that carbon would not be worth the effort.
But maybe somebody knows of a good supplier here in the states.

I'm curious myself. I break the carbon booms infrequently but I wouldn't mind cheap replacements

Wow, it is not worth the effort in carbon or metal.
You just can't beat china prices.
I guess it is going to be Chinese made.
And more sim time.

LOL I hear that. It's hard when you can't even buy the raw materials for the the price of the finished product.Heli-itis sufferer.

Right!
And they are on the other side of the world.
And still cheaper than anywhere else.
I don't get how they make it to afford that cheap.
Well, yeah I know how, I just don't get it.

I'm thankful for low (relatively) prices but so long as we have good solid choices. Once something is created, it's a race to the bottom. I've seen cheep cheep cheep (and crappy) servos for $4 lol, I'd charge more to put the sticker on it and put it in a box

FWIW I use both metal and CF tail booms on my 450's:

Aluminum usually bends instead of breaking in a crash, so is less likely to wreck the tail belt.

CF is lighter, giving better performance and making it easier to set correct CG with the battery in front. It often breaks off at the boom block in a crash.

I keep thinking I'm over crashing and install another CF boom. Then the next repair cycle I use aluminum in penance for the unrealistic attitude!

Full carbon fiber on a 450, NO! very bad resonance.
Try to make booms yourself, NO! not cost effective.
OEM aluminum booms are the best, but you can try the cheap aluminum booms from Xheli.

Align Carbon Boom
In my experience, the carbon boom on my 450 DFC is the better option.

If you fly in places where you will get large temperature swings from heli workshop to flying site, and you fly a 450 with a belt driven tail, go with the carbon boom. Belt tension will remain relatively constant with a carbon boom. With a metal boom, the different expansion rates between the belt and metal boom in temperature change will cause the belt to go loose moving into a colder environment, or too tight if you are moving into a hot one.

Of course, if you are crashing every time you go out, use the cheaper metal boom because you'll be replacing it and readjusting the belt tension anyway
