Has anyone tried using a carbon toque tube in the hawk or raven boom with success? It can't bend out of true, only snap in a mishap.

Century's torque tubes all used to be carbon. Besides the Predator Max(which is why they switched material), they all worked just fine.

I have the Carbon fiber tube in my Hawk Sport, and it works just perfect. Some time ago the Hawk had a boomstrike (due to a bad auto...). The boom was toast but nothing happened to the torque tube.

Reaven carbon
The older Raven kits came with carbon and I have used them for years and still have a few. Never a failure. When the larger P-max came around they shreded carbon rods so the change was made.

The SS torq tube is the way MFG are going.

Yes, I thought as much . I can understand aluminum in the higher torque machines such as the predator. Thanks for the replies.

I've gone into the local hobby shop and picked up an aluminum tube, same diameter but a fair chunk longer and used it. The tube is a bit thicker as well, cost was under $10.00.

I had to heat the dog bone in the old torque tube to get it off and used green locktite when I put it back on plus drilled a hole could put in a set screw. The Aluminum is soft enough that the set screw will create its own screws - used a bit of blue locktite on that. On the other end, basically did the same thing to get parts off (and back on again). Had to use a torch to get stuff off.

I'll likely try this for my Raven as well.

The reason I like the new metal tubes is you can tell easier if they are good or not.

The carbon tubes because they are not spiral wound could 'splinter' internally in a crash, and you would not be able to tell until they unwound in the air (don't ask how I know). That was though the only time I ever had a failure was when I used one after a crash that I thought was ok.

I do not believe they would just unwind with normal use. However, I would not necessarily trust it if I touched the tail to the ground in any way.

This is why I am REALLY happy they went SS on the tubes for all the products.

Trevor.
