HK450 carbon tail boom

 Madog 7 points

It will fit for your HK-450 Pro TT,I just order 5 pces and fit them with torque tube GT450pro-145 no problem. The dimensions wrote on description item are not correct, I measure with calliper OD is 11.9mm and ID 11.06mm Tot length is correct 347mm. The only thing missing is the small hole for the tail unit but you can easily do it your self, it's even better as you could adjust it as you like for perfect fit. Thx HK :-)

I have crashed with this boom and it survived perfectly. where in a similar crash my alloy boom was badly bent. So to answer part of your question: yes it will be much stronger and bounce back from stresses well.

This one does not have tail unit position hole, the second one HZ018 has. PS. I only have order this one and it is without hole.

I just bought 2 of each, they are so cheap even if i only get 2 that work well it will still work out cheaper than RJX CF boom on other sites.

No, i have the hk450 pro and it's not too big for me. I have bought some of these and all they will fit. Marthijn

Yes its to big, the outer diametes is 12.45mm, must to be 12 mm

the outer diameter is big for the HK450v2 too. I have 2 of them and 12,3mm and 12,2. anyway it fits good fot the tail rotor but I can tight the tail holder piece to the end.

everything is possible but very difficult. you would have to do some pieces with a lathe to build it. nothing is impossible, good luck

just do it, that is the fun part of being a hobbyist.

I had it mounted on HK 450GT. Work´s good, But look at all mounted screws in the rear, because vibrations can shake them out! :)

I mounted it on 450 v2 and no problem at all. Aluminium is 17g - this one is 10g so why not try it for the little money!!! I am happy

does not work 4 the pro

The pro requires the 12mm diameter one.

Product=10981 fits my 450GT Pro just fine. This one listed here seem to be too fat. 12.45mm instead of 12.00mm.

Very interesting. Multiple samples of 10981 do not fit on my 450GT pro's tail unit: the OD is too large. Do you have a caliper to measure your 10981 sample's actual OD?

I surely hope they will fit my T-rex 450 Pro and Tarot 450 Pro I ordered a few of them...

 Wireman 345 points

Ragamofyn, I measured my 10981 with a caliper today, and it's between 12.02 - 12.05 if I turn around the diameter of it. Maybe you got yours from a batch with a larger diameter. Mine fits just fine for the 450 Pro I have.

 ragamofyn 256 points

Thanks for that information, Wireman. I'm going to check over my own 10981 and see how it compares with your measurements. Thanks again for the effort. Much appreciated.

 ragamofyn 256 points

I just took a sample of my 10981: 12.21 at the boom clamp end, 12.38 at the tail rotor end (worst case). Thanks for letting me know, Wireman. I'll try ordering some new 10981s and see how they work out.

Today I received this 17126 tail boom and it's between 12.05 (boom clamp) and 12.18 (tail rotor. And it's 53 cents less compared to the 10981. A little better deal then! :-)
