It is back to set up. I think a well set up belt "in theory" should be able to hold its own against a torque tube when it comes to effeciency. But in my experiance, if I spin the main blades the belt driven machine allways stops first.
I have found the same thing...

Belt vs TT

This will probably still be debated long after I've permanently stiffened up. I've had nothing but trouble with belt drives slipping regardless of how tight I make them. About the only exception has been the Raptor 30 which didn't have enough power to get out of it's own way. Every 50 size or larger heli I've had with a belt drive has worn the belts out, slipped, broke, or some combination of the above. I've flown my Trex 600E back to back belt vs TT and the heli has more power and autos better with the TT. The belt on mine was also starting to round off the teeth after only 25 or so flights with the stock motor and it was just a question of time before it started to slip. The setup for the TT is easier on the Trex because there basically is no adjustment on the gear mesh and the belt tension does have to be adjusted. I've torn out the t/r drive gears 3 times on close encounters with the ground which did not involve crashing the heli, so the cost is more even though I haven't crashed the thing and needed to buy a new TT. I'm not your usual flier and spend more time going sideways and backwards than I do forwards, so I stress the tail more than most and for me the TT is clearly better. If you'd asked the question 10 years ago when I couldn't fly backwards and was crashing monthly, the answer would have been different. There's not a right answer to the question, I think it depends on your skill level and how much you can afford to crash. Hope this helps. steve.

I think both the belt and torque tubes have their place for different situations in the hobby, niether one is really superior than the other just have different strengths and weaknesses, what is more important to you(more efficient torque tube more complex set up or slightly less efficient and less complex set up) is all that really matters anyway.

fwiw, I prefer the TT. I can huck it around pretty well, and I "feel" the belt load up in piroetting manuvers.

Thanks for everyone's input.

Yep, if you have two identical helis, as oldfart mentioned with his TSK's or as Steve9534 has said about his experiences with the T600, I agree, there are areas (specially in the auto) where ANYONE can feel the difference.

And under high power loading (50/60/90/gasser) and driven through hard tail rotor maneuvers, a belt becomes VERY HIGH maintenance as Steve also mentions.

So I to prefer torque tube shaft drives.

And Zaneman

One does NOT necessarily have to pay MORE for a good heli with a good shaft drive system. Your Hawk Pro is one example as are the 50 size Raven which has an even better shaft drive (the same as the 90 Predator, just shorter).
