20x20 Spacer

I bought the Falcon CP130 frame and the Spedix IS100 20A Mini-Tower. The M2 4mm stand-offs that came with the mini-tower was killing me.

Thus, not leaving any room on top of the stack to fit an FrSky R-XSR.

So, after tearing the cheap Lipo strap that came with the frame, I decided to take everything apart, design my own hollowed out spacers 4
