Hi all.
A relative newbie to RC heli flying and still learning the basic art of hover.
I built up my model about 12 months ago, adapting it with a number of metal upgrades as guided by EVERYTHING cpo's excellent build You-Tube videos.
Loving the model. however one observation I've made is that I'm wearing through the torque tube bevel gears within approx 8 to 10 flights - this is low load hover flights I'm talking, not heavy 3D. Early flights I can put it down to ground-strikes of the tail rotor, however I've been very mindful to avoid this and haven't had a single strike on the current set of gears. However the last flight this afternoon showed the tell-tail signs of tail rotor slippage with the tail starting to slide anti-clockcise.
So my question is, what would a typical life-span of a set of these nylon gears be, given my type of flying? I'm wondering if there may be too much play in the system and whether doing something like slightly over-sizing the tail-mount bracket fixing holes in the carbon side plates may be needed to allow some tightening up of the gear meshing?
Thoughts appreciated please.
