As if the Q X7 wasn't solid enough, FrSky has released the QX7S. The following is a list of the components that have been upgraded.
First on our list are the recently released M7 gimbals. If you're not familiar with the M7's, they are a Hall effect sensor gimbal instead of the stock potentiometer sensor. What this means, is that the Hall effect gimbals will outlast the stock gimbals, while also remaining very accurate throughout their life spans.
Adorning the aforementioned gimbals are FrSky's, bronze Lotus stick ends. The Lotus are an exceptional stick end, comfortable and non-slip even under harsh conditions.
Last on this list of goodies are the higher quality than stock switches and pots. They feel smoother to the touch and will out last the stock switches by many cycles.
This concludes the "Special Edition" aspect of this write up. If you would like additional information pertaining to the stock Q X7 click here.
