FMS 1700mm F7F Tigercat Wing PCB  Board Connection recommendations

On the PCB fuselage connection board and for those having a few intermittent cut outs...I recommend this as a quick simple improvement:

I took mine out and sanded the edges of the PCB board to loosen the tight fit in the plastic square it sits in (It doesn't take much). I then slightly oversized the four mount holes in it and backed off the screws about two turns to add wiggle/slop room around the existing screws, and this will allow the PCB on the fuselage sides to have free play in them and flex-float (Pivot) up/down in relation to any wing flexing going on... (Leave the Wing side PCB connection board tightly secured as it is)... (You can even take it a step further and remove two of the screws that are kitty corner to each other and it will free float even better)

This will still allow you to maintain the convenience of the current PNP wing setup, without having to manually plug it in or unplug it. 

Both Rich and I have done this to ours and haven't had any problems or glitches.

In addition...I also recommend running a bead of something like Foam-tac arround the two servo type connectors that are on the back side of the PCB to additionally secure them in place and to the board itself. Same recommendation goes for the PCB board connections in the wings. And as always....make sure to check the fit of the connectors and that they are fitting firmly.
