My Logo 700 has recently passed the 1000 flight mark. This heli has been virtually faultless in that time. This heli just flys and flys with a minimum of maintenance required. I have typically stripped it down around the 450 flight mark to do some preventative maintenance like replacing torque tube umbrella gears and various bearings. In reality, most of the bearings and all of the gears have shown no real signs of wear. I replaced them anyway given the heli was already apart.
I fly reasonably hard 3D on this heli. Literally the only maintenance I do routinely on this Logo 700 is replacing the plastic ball links on the swash to main blade grips every 100 flights or so.
What an awesome heli!
