Well I haven't done much at all I had too much revision to do and I was on holiday this half term. Im thinking of adding a flipper but chances are I wont as im not sure which ones are good or how to attach the mechanism to the arm (I have heard people supergluing them on before) but anyways I did have thoughts on just selling it but no I wanted to build it but so far nothing really has happened other that I started to cut the polycarbonate and then just left it cause of revision. There is nothing interesting about it anyways its going to literally be a block .

Barracuda: Beetleweight Vert... hates working...
For my flipper robot, I just super glued the flipper arm to the servo horn and installed the servo on top of the robot. simple to do and it usually means you get a good ark of movement, just don't let a spinner hit the flipper at any point.
Its really not complicated. What are you having trouble with. Also what crystals are you on about? I thought pretty much everyone was running 2.4ghz now
