Default Signs your K3D Motor Mount Rubbers are Worn

1) you break the lower rear crossmember that secures the boom supports

2) you tail starts drifting in a hover

3) strange rattles suddenly show up during flight

4) governor sensor breaks

5) duh! you can easily twist the motor


It's one of those things that you just don't notice going bad (like your vision or losing hair) until it's really bad. I would recommend that you add the motor mount rubbers to your annual maintenance on your K3D, or every 6 or 8 cases of fuel. Since it's a unique feature to the K3D, it's something that I just didn't think about until my heli started shaking itself apart.

Thanx for the tip HD. That sounds like just the sort of thing that would bite me in ass sooner or later.
