just curious to know what the advantage of having a torque tube on an rc helicopter is ? I would think it could get frustrating if you were to strip out gears or the thing would vibrate alot if the torque rod were to get bent. I know there are down sides to the belt drive as well but would you guys think it would be worth it to get a torque tube conversion for trex 450se v2 if they were to make one. I saw a listing (I think I saw it on helihobby.com if I can find a link again I will post it) for a torque tube conversion for $81 but it said they didn't have a release date yet. I also heard that the trex 450 pro was supposed to have a belt drive option, is this true? so again what do guys think? to torque tube or not to torque tube?

the advantage is align gets to sell higher priced replacement parts.
j/k

tourqe tube is a bit more efficient, but obviously not as cheap to replace in a crash. honestly if i could pick, i'd go with a belt on the new 450 to begin with and put the torque tube in when i feel real comfortable with my flying skills. i'm still learning 3d an pretty prone to crashing.

Until there are reports from Pro owners, will one be able to judge for themselves which is better. Once the hype settles, I suspect we will be getting some reality based information. Like everyone, I had trouble with the belt system but resolved it long ago.

TT is much smoother to fly and certainly much more efficient. However, when I crash my T-REX 500 ESP last week, I have to convert my tail drive system to bell drive because of the replacement cost. TT system cost around 2X to replace after crash.

I will put it back on when I am more comtable with it.

Thanks,
Alan

I am not sure you can tell a difference on this small of a machine. Looks to me like Align just wanted to sell more parts each time somebody crashes

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

Hey, some of use have asked for TT on the 450, Align listens. As far as why, I think they have a pretty good idea going, they are moving the mass closer to the mast. tail servo is farther forward, and in the middle. The TT should give better Auto performance, and people say it is more precise. It won't take long for people to make hybrids, add the head to there V2, or put the tail from their V2 on the Pro?

In my personal case, when doing tic tocs (nothing fancy), fast flips, the tail yaws sometimes because the belt slips, no matter how many times I tight it, it is always the same..... I am changing to TT in one of the helis.
In normal, slow flips, you will not tell any difference....

I've had belt drive and now have the Pro with the TT.

1. If you have problems hitting your tail on ground, land on grass, or around rocks, go with a belt drive.

2. If you can consistently land without hitting the tail, TT is fine.

3. If you crash a lot, go with a belt drive.

I personally really like the TT. No more adjusting belts! No more worry about the belt snapping! I went with a TT after my crash with the 400 when the belt snapped while hovering over the street in my cul de sac. It was ugly and really pissed me off. The whole TT tail system comes off with 4 screws. I am not good enough to say if it performs better, but I really like it.

BTW, the belt system that EXI has for the Pro conversion really sucks. I stripped a belt out in a couple of flights and is a poor design.

It makes a big differance in 3d but not sport flying. In hard 3d the belt would slip no matter how tight it was but to tight is bad and you will loose flight time. with the tt there is no tail slip. If your a beginer go with the trex 450 sport. or atleast take the tt out and put a belt in.

I don't believe that to be entirely true. I have watched many heli's with belt drive perform fantastic 3D without belt slipping issues. True that the TT is more efficient, but a belt drive isn't the end of the world either.
