Got my new Open tail rotor G/B

I think that the now open gear box runs smoother..its deffinately quieter

I have to get a new one. I heated it to much and the C/F rod broke. I could probably fix it but why take the chance.

The new gearbox seems to be a lot more free as well. Some of the top pilots flying them have said they can tell a big difference in their autos and maneuvers that require a lot of power. The other major obvious benefir is no gear mesh to adjust and no greasing to keep up with!!

Good enough for me, gotta get me a couple more.... I like simple

You may be right.... I only have a few flights on mine;and Im fighting a TJ that refuses to work..I got it second hand so I guess I gets what I pay for..hehehe anyway new TJ ordered and when it comes in I will be putting the time on this one for sure....Funny I have never once looked at the gear mesh since I installed this Open G/B..just to new to worry about for now...

I noticed that when I hold the tail and head and I try to turn the tail to see how much backlash the new box has I noticed that if I turned the tail with more force the torque tube would flex more than with the old tailbox. Has anyone noticed this also?

Love my new gearbox, now if I can get more time on it I'd be happier

Don't know how the different gears would cause the TT to flex more unless you are applying more force w/ the new gearbox????

[DavidH]

If the torque is flexing, I would be pulling it out and checking it for cracks along the length of the tube. I take pliers and hold each ball coupling on the end of the tube and I can not twist it. So what you might be seeing is slack between the couplings and also the front gear mesh.

I've got about 10 flights on this new gearbox..Yes in the sand..No wear showing at all..its Smooth....I really like it..I have 3 old style spare gearbox's now..I just cant justify ordering another open gear box...
