Got my V3TT from Flying-Hobby and have done a bit of hovering with it. Very Smooth. According to EagleTree, 2.5amp reduction in hovering power draw with the TT. I like it!

torque tube

i hovered around a little yesterday and i agree with 727driver. its very smooth and i noticed a considerable amount of extra headspeed. Its amazing how much power the belt was robbing from the motor. Its a very nice upgrade and well worth the money.

Funny how a few years ago, when my HB 3dpro had a great torque tube setup, I was convinced to put an expensive belt drive tail system on it.

While the tail was nice and smooth with the belt, it was way to fiddly. Come to think of it, the main reason why I put the belt drive on the 3dpro was to save on the crown gears.

Anyhow, is it now conventional wisdom that a torque tube is better? What about maintenance and repair cost. Do the tail blades snap leaving the TT setup intact or is TT replacement mandatory after a crash.

Just wondering out loud..

On the 450 Pro originally the TT was CF and would separate from it's ends or break when stalled saving the crown gears and making the repair as simple as drop out the tube for a new one but people complained about it I guess they think the tube should be indestructible so Align now ships the Pro with a metal tube which will not break before ruining the crown gears making repairs a PITA but I believe the CF TTs are still available as replacement part though

I have a V3 TT upgrade on order yet for my V2 so I don't know which tube it comes with - I don't expect to be stalling mine often but I know I'd rather just swap out TTs than completely disassemble the tail and press off/on crown gears

In a crash that bends the boom I'd expect to replace the drive whether it's a TT or a belt but with a TT a gear might go with it and not likely so with a belt

Partially correct, the first 450 Pro TT was black aluminum, not Carbon. It was designed to snap in the event of a crash saving the gears. Then in the second or third batch of 450 Pro's they came out with the silver alum TT and started placing those in the kit. You can still buy both as spares, so you can choose which you would like to run.

Ah good to know about being incorrect on the CF and which is what since they're both metal then - Thanks

Oh this TT drive is sweet - Smooth and efficient especially compared to my old belt drive that was plagued with tracking issues to where I had to run it tight which really robbed power etc - And hard to believe how much vibration was generated by the belt drive - TT drive is so smooth and steady - Wish I had this a year ago - Lucky guy I'm selling this to won't have to put up with the belt issues that I have for so long anyway

Looking forward to some night flying at the Othello FF this weekend
