The M4's do NOT fit Stock Taranis or Q X7 gimbals.
The M4 Stick ends only fit, Horus, X9E, M7 and M9 Hall Effect gimbals
Super duper, very "sticky" stick ends, available in 4 styles and in four colors. Featuring a nicely machined no slip surface. Definitely one of the better stick end designs I've used.
Both the Lotus, Grand Lotus and the Umbrella are super grippy sticks. Great for thumbing it, or using hybrid grips; while the Pole on the other hand, is smaller in diameter, almost smooth on the sides and the top, and makes a great pinch stick.
