Mixed day

I got CB100 #2 up, trimmed and flying. Needed to move the pitch servo linkage out to the farthest attachment to get the control I wanted. I wanted to do that to the roll servo, but the end of it is broken off, so it stays where it is. I'll be buying another one of those...  But it hovered nicely in the Man Cave and gave me some satisfaction. Still waiting on parts for CB100 #1 which continues to be grounded.

Took the UFLYS out to hover, still a little breezy. The damn thing remains very unstable, not at all like others enjoy, even in dead calm. As it gets light on it skids it starts to get ziggy, and as it lifts, it is off an running in some odd attitude. It runs off in different directions each time, so its hard to figure out what is wrong.

I will never buy another shaft driven tail rotor heli unless it has its own motor at the end of the shaft as this UFLYS has been one problem after another. Despite my repairs, the slightest blade of grass causes the shaft pinion to grind unmoving on the main gear. The rotor shaft remains snug, so that's not the problem. Took the tail off and the pinion looks good. I did break the bolt connection to the tail "stabilizer", so I may have to buy a whole new tail assembly.  In removing the tail boom the connector piece that hold the horizontal "stabilizer" and the boom supports, as well as the rudder linkage broke. This thing is so fragile... I will need to replace that as well.

So far it seems these Walkeras, in my experience, are those "money pits" that John Salt warns us about.  I haven't gotten one to fly normally, except the single CB100.  Not sure I will buy another one.

Addiction is in coming back again and again despite the pain... I am addicted.

UPDATE: Hmmm... I wonder if the broken H guide of the rotor linkages is allowing the swash follower too much play? I thought about this looking over the a/c. This would be nice, because it means I could soon have that balanced heli.
