had 3 600's 2 had TT and the other was belt. the TT helis always suffered more parts damage than the belt drive.after spending too much $$ repairing TT's I switched all my helis to belt. Now if they would make me a belt drive for my N9's I would be happy.

I'm the opposite I will take a GOOD TT setup over a belt every time.

the performance difference is pretty different specially for autos.

if you like to RotoTill dirt with your tail then belts are a better deal for you.

TT better power distribution,better autos stronger in all ways,in a crash you lose it 90% of hte crashes lol is more expensive than belt

Belt you can touch the ground with it and no gears are loss is alot cheaper,well in hard manoever you can lose tha tail but you can still fly hard 3D

a little of what I have heard if any one can help me in this info welcome,hope this helps for you

Not really.. Unless you land on the tail and break it off.
most crashes eat a very cheap crown gear and even that isnt all the time.

the torque tube definately seems to be more efficient. Here is my thoughts for the ones that say it cost more in a crash. Yes, they do cost more however if you are running a torque tube, most of you are not newbies anyways and besides the occasional dumb thumbs, you shouldn't be crashing all that much anyways. Sorry, had to get that off my chest

It's a complex, costly, glow powered anti-gravity machine!

My Century Raven has a TT and I've crashed it at least 5 times and I'm still using the same torque tube, and yes I've thoroughly inspected it. They don't always break.

...now where was I, dh/dt = BS-dx/dt
I will fly you forever... till earth do us part

Torque Tubes are more of performance parts. I wouldn't recomend them to people that crash quite a bit. The Torque tube will give you much better performance.
Belt drives are just fine too, but depending on your positioning of the boom your performance may vary.

I have never noticed any performance difference or loss of power due the belt, also the 600's I had auto'ed the same as with TT's.

I'm still bumping my tail rotor occassionally during those not so perfect autos. All that tail has 2do is graze that dirt and I'm changing a crown gear on my 600N. Is it expensive? Heck no! If I can walk away with that kind of minor damage I'm happy. Ok ok.. I could probably pickup my heli and go again with a belt drive but I favor TT because it autos better and I can pretty much install it and forget. Either way, they are both reliable systems .

TT vs Belt drive

My vote is for the torque tube over the best as everyone has stated in the past about better auto's for sure. I also find that the belt is more of a problem with the temp change than the TT. It can get really loose and rubbery.

It seems that every heli that has a TT someone wants to change it for a Belt and vis versa. That is what keeps this hobby busy and interesting.

Their are a number of different belt drive designs, just as there are a number of different torque tube drive designs.

The best belt drive design may be superior in a crash and maybe even in performance then the worst torque tube design.

But the best torque tube design, is better in performance, dependability, maintenance etc. and about as crash resistant (as aluded to by QuantumPSI) as the best belt drive...so I will take a good t/t drive any time.

TT hands down, for ease of maintenance. It's way easier to replace a TT than to replace a belt, plus if you fly electric heli's, TT will generate less static.


Man these Ford vs. Chevy debates are entertaining.
