Mixing throttle and rudder

Thanks. I'll have a play with those Tx settings when I get the boat back on the water, hopefully next week. Currently in dry dock being re-painted. I think the expo setting for the throttle should be useful.

While waiting for the paint to dry between coats, I have put together a mixer which, if I have it right, monitors the rudder demand and uses it to impose a maximum value on the throttle input to the ESC. As the turn gets sharper, the maximum throttle demand to the ESC is gradually reduced. That should stop me hitting a turn too quickly.

I did this, well sort of, by using the settings in my transmitter, which at the time was a spektrum DX6i.

You use dual rates, and exponential settings, I would imagine most modern 2.4 sets have this feature.

In simple language, dual rates (D/R) will limit the throw, so by experimenting you flick the switch, and all of a sudden you have limited the throw of the rudder, flick it back for slower speeds and you have full movement.
Exponential (expo) nulls the centre stick movement, and is generally on the same switch, so it makes the stick (rudder) in your case less sensitive, so easier to use at higher speed.
Just remember though, most transmitters and receiver have aeroplane terminology, so, if your rudder is right stick, this is labelled as the aileron in the instructions, menu and so on

Having read somewhere on this site ( I can’t find it now!) that turning a 34” crash tender at speed can be a problem I have been thinking about ways to Reduce the risk.

The obvious way is to pilot it carefully, turning gently, or slowing before turning sharply. But that requires the pilot to be paying attention. I’m not sure my young grandson would take that care, even if I do.

So, is it a good idea to mix throttle and rudder to overcome this issue. It seems to me there are two options:

1. Reduce the rudder throw based on the throttle setting. i.e. mix such that as the speed increases, the maximum rudder throw reduces. Or
2. Reduce the throttle based on the rudder demand. i.e. mix channels so that the boat automatically slows based on the rudder demand.

I haven’t found any reference to this on this website, which make me think it isn’t a good idea, but I would be interested in any thoughts from those with much more experience than I have. Also, can these mixes be set up on an fs- i6x transmitter?
