There are two of us that fly the same plane. I like the iFly mounted on the Velco radio panel while the othe pilots likes the yoke mount. I found that the special nut that attaches the ball to the iFly comes all the way off when taking the ball off and it is hard to get the nut into the slot of the iFLy when putting the RAM ball back on. The solution was Loctite in the nut. It holds the nut tight while screwing the RAM ball on and off.
