First image showing that the screw isn't stripped. Second shows 'notch' that fits over shaft and third showing how the screw should be. Hope that helps.
Hi guys
I'm a noob to quads and bought a toy grade just to get me started. The XK had great reviews and I ordered one from ebay, took a month to arrive from China and against my better judgement took it out in to the garden for a brief flight when the wind had dropped enough.
Cut a long story...
