Thank you for the quick response FLYBOY.

I have a Venture. The screws seem PRETTY secure (that is they won't fall off) but I 'm just afraid that with the vibration the servos may come loose. They just don't seem tight enough.
I
have a JR Venture, and I use the screws that came with the servos and not the ones that came with the heli (silly move, in retrospect). Should I replace them or just go with what I have?

The 811 servo screws seemed slightly larger than the heli screws (I think -- I don't have them in front of me now) but they went in the tray fine and without any strain.

Thank you
