FlySky FS-I6s transmitter Review

I ordered and received my new Flysky FS-I6S recently and I love it.

Get it here.

I bought this transmitter for 2 reasons. Firstly, its cheap but by all accounts it will last well and give me a good run in terms of learning to fly FPV and moving through a range of beginner quads.

It takes actual AA batteries which puts it in the beginner category as more advanced transmitters will use LiPo’s but that is actually an advantage for me as AA batteries are easier to source than picking the right LiPo and connectoer etc.

The second reason ( and why I bought this before buying my first FPV quad) is that I wanted to spend time learning on a simulator before breaking a brand new quad.

I bought the Liftoff FPV simulator and at first used a Dualshock PS4 controller. That proved to make flying very hard and I knew that if I was serious, I needed a real transmitter.

This is the point that has really impressed me. All the indications were that you needed a trainer cable which is a little but awkward to get and will cost around £15 but when I received this transmitter, I tried plugging it into my Mac via a standard USB cable and it was recognised as a controller straight away meaning that I could practice  and get as close to real flying as possible.

The FS-I6s Looks modern and has a quality feel to it. I have used it for over 10 hours on a simulator and the batteries are still at around 50% which is fantastic.

The tough screen interface is smooth and there are loads of customization options. The switches feel solid and the controller can handle up to 10 channels which will be more than enough for you.

It is easy to update the firmware in the FlySky FS-I6S.

The version that I bought has a self centring throttle which isn’t how I like it (although it may be exactly what you want). If you don’t like it though, all the parts to change that are there in the box and all you would need is a screwdriver to make the modification (and about 5 – 10 minutes to do it carefully). I will post a video of exactly how to do it below.

The one negative thing about this quad is that it only supports FlySkys new AFHDS 2A protocol. This is way better and more advanced than is predecessor AFHDS but for the time being (early 2017) very few micro quads with integrated flight controllers and receivers support it. I am primevally referring to the Eachine QX series below the QX105 BAT. However the newer flight controllers do support that protocol so I don’t think its going to be long before it will be easy to get micro quads that it will support. The Bat and the more expensive Brushless quads do support that protocol for the most part so I wouldn’t let it put you off.

I got caught out be that and so because I really wanted an indoor micro quad like the Eachine E010S, I decided to get the parts with an upgraded Flight controller/receiver and build my own. You can follow along with the build log here.

There isn’t much more to say really other than I love this transmitter and would highly recommend it to anyone wanting to get into FPV Quad flying.
