+1 to the auto capabilities of the Hawk Pro. I find mine autos better then my belt driven 50's. I have installed the optional tail driven auto unit in mine. I find that the shaft drive tail takes much less energy from the rotors to turn the tail rotor in an auto, then do the belts.

I also like the dogbone coupling of the Hawk's torque tube. It will allow the boom to bend a fair bit in a crash before needing to replace the t/t. I find it has much the same crash survivability as the belts in my belt driven helis.
