Ed,

I agree that the manufacturers need to address this issue. I've built more ARF's in recent years than kit's due to work and family... a full time job and 3 teenagers at home take up most of my free time... I either slap together an ARF and fly or build... I'd rather fly I've had to adjust the tank height on most ALL the ARF's I put together, I'd rather do what I know is right the first time than get out to the field and have trouble because I didn't move the tank to the Centerline or very close to it. It's been, in most cases a simple fix... why the manufacturers don't just do it right the first time is beyond me.
