Post some pics of your setup and even a short video of the servos in operation.

I can try and loosen the links to check if thats a problem (how do I do that? My ball link sizer is meant for the smaller ball links found on hirobo type helis).
Just remove the elevator link one end at a time and move it with your fingers to see how tight they are on the balls. If they are tight you can give them a little squeeze with some pliers with them attached on the balls.

60% of the time, it works every time!

Had to ask the first-time heli question.

Appears something in your pitch cyclic isn't returning to zero each time.

Here is a shot in the dark... Is the swash itself healthy? Are the inner and outer races of the swash firmly linked together? I've had swashplates begin to come apart and it was a little hard to trouble shoot.

Good question Bill but he says it only either drifts backwards or forwards.

Oops. Sorry. I missed that detail. If it only drifts on one axis it's probably not the swash. These types of problems are really tough to trouble shoot without actually holding the model....

I haven't programmed a VBar. Does it have a "Dead Band" setting?

Your swash plate may be bent
- check to see if balls are perpendicular to a leveled surface
- if possible, compare against a known good Swashplate

I had bent a logo Swashplate and even though I used a Swashplate leveler, it was drifting.

Worst case, mechanically adjust the swash to Servo links to offset the drift
He says it can drift either forwards or backwards.
