I have these, only done short testing so far, the instructions are pretty useless, however the same set is manufactured in other names, flysky being one of them. If you google flysky they have downloadable instructuions, which are quite good.
Couple of points to mention.
A lot of the programmes are designed for rc helicopters (I also fly these) so some of the terminology can be a bit confusing if you are not familiar with it. You keep your particular settings in a folder on your pc, so really model memory is infinite, you plug in the tx to the pc (lead supplied) and open the relevent folder!, so when you are at the lake, that is the setting you have. For a boat thats no problem really, as the sticks will be doing the same job (except if you have a programme/boat with different mixing?)
The left sick does not have "self centring", as a helicopter cannot have this, and there is a ratchet on it, so for boats, you have to open up the tx, take the ratchet off, and I used the self centre action of left and right on the throttle stick, and moved it to give self centring on the up/down travel on the left throttle stick (assuming you want standard uk mode 2 throttle on left).
I have made a disc that goes over the left stick, as the left/right movement now has no function. The disc has a slot, so the stick only goes up/down. THe riight stick is set up for rudder (left/right), but it also goes up /down, this is an extra channel, for me, this has no function yet, but I was thinking it could be used for twin screw mixing?
2 knobs on the top, I have set them up for turning a fire monitor, as they are proportional knobs. 2 switches on the top, I set these as firstly nav/cabin lights on and off, and the second for smoke generator on/off, or fire monitor pump, depending on the model.( I bought 2 receivers)
THe rx aerials are notoriously brittle, helicopter forums are recommending putting a blob of glue on them to make it stronger. When delivered the first rx was bound, it took minutes to bind the second rx. THe tx has a good quality feel to it (for the money). I do however want to do more testing before the set is used in a more expensive model. A friend bought a set at the same time, he has been testing in rc cars, and has said the range is shorter than that of his 40meg set, but I have not experienced this. Here is a short video of my youngest thrashing about with the turborix set (looks like there are no "splashes breaking the signal" )problems http://www.youtube.com/watch?v=tJIeAievxps
