Be careful with the CF tails. I know some folks run them without problems but I've tried two different types and shredded the tail section of the t-rex 3 times. The piroetting autos were fun. They actually weighed less than the stock plastic tail blades and were balanced but I guess they're just somehow too stiff or something.

Can you elaborate on "shredded the tail section"? What exactly broke and how?

Thanks,

The tail nub is the component that breaks. I have had a few of them EXPLODE while in the air. The aluminum is not strong enough to withstand the lateral forces exerted by the carbon fiber tail blades. The lateral forces are greater since the carbon fiber tail baldes do not flex. This means that the movement of the tail blade is INSTANTLY felt by the tail hub and grips. The grips are held onto the hub by a short 2mm screw. This transfers the entire lateral load onto an extremely thin aluminum tibe that has been tapped. All of the lateral force is felt by the hub and the aluminum cannot hold up to the repeated sharp loads.

Those are stock plastic blades, just made to look like carbon fiber "Fake Carbon fiber" They will work just fine.

I have the metal tail set. Will that be able to take the stress?

What stress? the blades are just like the white & yellow ones only with a fake carbon plastic pattern of some sort, and the align metal tail set is made to handle the stock blades Unless you are talking about some 3rd party blades and then the other factors might come into play.

nice! that hub looks promising. Maybe I'll get to use those CF tail fins after all.

how long does it normally take their parts to show up in the U.S., or are they already here somewhere ? thanks.
