I think that the the brushless tail would work. Or a belt or gear driven tail would be good. But I would look at the cost. It seems too much for me. There really are better heli's out there for not too much more money. I am ready to write the cost of the Axe off as a learning experience. I just think that anymore upgrades to the Axe would be a waste of money. Save your $ that you would spend on the Axe to upgrade and just get a better heli on your next purchase. After all, we all need to learn on something. When I learned to fly planes I spent way more money just to learn to fly that I have on heli's. Tech has made learning to fly with any airframe much easier than it was 10 years ago.

If you do these upgrades I want to hear just what you have done. I am sure that everyone else will want to hear too.
