banana tt

chrismechanic · 06-04-2011, 06:58 AM

hi guys...after a tail strike and a crash, my tt drive is kinda bent...not too bad but its causing vibes and i still have the loose tail syndrome.
just using 1 tt bearing atm....
so i bought a new tt and boom ....H55034T and it arrived in the post in a tube so no damage from the postman....
this is a pic of the tt drive sitting on a granite flat plate...accurate to within .002mm
imo, its a shame the tt is not accurate to within 1mm

let alone .002

I've recieved some pretty bad one as well, you should see some of the aluminum ones I get for my 450, man they look like a pretzel.

Just wondering if this is not another reason to use belt drive? As a person just learning to fly it especially makes sense. I looked at TT from my original setup and it is not quite true either. I also suspect is why two bearings work better in some cases.
