I wouldn't rule out a particular heli because it has a belt driven tail.
I've owned both. Each has its own pros and cons.

There used to be a Torque Tube vs Belt debate almost as often as there was a Electric vs Nitro and Pinch vs Thumbs debate.
It's been a few years.

The only performance benefit that torque tubes have over belts is a little extra reserve at the very bottom of an autorotation. That's it.

Chocolate and vanilla.

I have both and they both "fly" fine. Minor pros and cons to both.

Some highly regarded machines have belts, so I would not rule them out....Diabolo, 7HV, Goblin, JR Sylphide F3C, Hirobo F3C machines, Furion 6, and Logo's (except the 800 Exxtreme) to name a few.

I have both. I have always been a fan of a belt drive system.

There are no performance advantages except that a belt driven machine will take abuse that a TT machine will not.

There are repair advantages to having a belt.
and
I can show you some pretty impressive autos with a belt machine. I think that one is a draw.

In all fairness, there are some machines that will have excessive drag due to the belt drive design.

Then there are helicopters that use bigger pulleys and properly designed belts that will not take a back seat to a torque tube machine in an auto.

The Goblin autos just as well as any heli out there with a torque tube.

Only downside is in the northen climates during the winter months having to re adjust the belt tension going from inside to outside and back again. Just a minor nuisance.

I had a Trex 600ESP with TT. It stripped gears on me 3 times doing tic tocs. I switched to a belt and the drag was bad causing the tail to blow out on side slides to the left. I now have a Logo 600 that flys much better than the Trex without stripping of crown gears.

High Voltage just works better

I would agree with you, if only you HADN'T included the words "back again". You make it sound like you have to adjust it every time you carry the helicopter through the door.
I mean, what are you planning on doing, flying a 700 size electric in the living room?
You should only have to adjust it twice. Once in the winter and once in the spring.

Rogman makes a good point and I mentioned it also.
Some machines are designed better than others.

Eddi, Have you actually had this happen? Maybe some belts do it more than others.
I have read this comment before and it confuses me. I live in a northern climate and I have never seen a belt change enough to require a re-adjustment. But...even if it did, we are only talking a few minutes or less.

Ray, I've had to do this a lot with my old 450 that was belt driven, as well as the Raptor 50. If not done, the belt would slap around inside the boom.

If you have a boom mounted servo, it's no big deal, but for frame mounted tail servos it was a pain in the ass.

I hear you Dood. Maybe they are cheaper belts.
I just dont see it happening here.

Yep, Logo is much better designed belt helicopter and the belt was one of the reasons that I chose it after my initial Trex 600 experience.

Ray,

Ed and I fly south of you near the Tappan Zee Bridge. The belts are not the issue. It's the expansion of the aluminum tail tubes.

If the tube expands with the heat (bringing the heli indoors after a day of flying in extreme cold) and the belt tension was set when it was cold, the belt will become beyond banjo string tight. Conversely, If the belt tension was set when it was warm (in your heated basement), and then it is cold out (say 30's or 40's) when you go the field, your belt will be very loose.

I'm sure you already know this.

Saying which is better in general is impossible. If either one is designed improperly, it will stink. Personally on a well designed belt versus a well designed torque tube, I would take the well designed torque tube for flight. Runs much quieter under loads and can make the tail much snappier due to the more rigid power transfer than a belt can give.
