ok, ill try to explain best I can, I'm sure others may chirp in and help if I go off in wrong direction, Its easy with the tx in my hand, so I am flicking between here and the instructions for your tx.
You have a plane or heli transmitter (tx). These can usually be adapted for boat use, usually, the throttle is not sprung to centre and it has to be adapted. The language in the instructions is all in plane/heli language. so to sort that out, assuming you have mode 2 throttle on left.
left stick up/down is throttle for boat and plane
left stick right/left is rudder for plane so therefore is rudd on your receiver
right stick up/down is elevator for plane
right stick left /right is aileron for plane and usually rudder on a boat
Before you start, select plane as type of model, otherwise you will be in a world of pain if you are in heli mode!
then stick selection (its called stick mode selection, model 1,2,3,or 4 in the instructions) you need model 2 (its getting complicated to explain now!
)
Power up the tx, and power up the rx (use 4 aa batteries into the bind/batt slot in the rx, don't overvolt it, and make sure you plug in then right way round), receiver should now be powered, or power it direct off your model without any servo plugged in, plug a servo into each channel in turn to establish what stick movement works what, so plug into ch 2, I reckon that's either throttle or rudder, so move left stick up, does the servo move, or move stick left, does servo move (sorry if you know all this!)
once you have the channels for the two stick movements that's 4 channels sorted, all proportional. Next is the gear switch top left of tx. its none proportional, on, or off. You can in the menu set travel adjustment to limit how far it goes, but that's pretty much it, that's 5 channels done. Now I'm sorry I started, cause its difficult to explain!
some of the switches are not channels, 3 that are elevator d/r, aileron d/r rudder d/r. D/R is for "dual rates", so, you are flying a plane, the rudder is way too sensitive and moves too far for your liking, making the plane difficult to control smoothly. You can set "d/r", so when the switch is flicked, it limits the movement, so the rudder now does not move as far. Same switch and setting also allows for "expo", exponential, which "dulls down" the sensitivity of the stick at the neutral position, so now its not as sensitive to small stick inputs. These features can be used for a boat. I have a large fast Electric brushless Huntsman. If I am on a large lake, I have the rudder d/r on, so I can take fast sweeping turns, without fear of piling in too much rudder and capsizing. If on a small lake where I will be going slower, I flick switch off, and can do tighter turns cause now I have full rudder travel, make sense??
Trainer switch top right, is for a buddy lead, so a trainee pilot can fly with a teacher, so no good for you
one channel, lets say number 9, is only available in a certain modulation, and way beyond my capabilities of explanation by forum, as you rx is 8 channels, you only have 8 to play with, so we have now covered 6 in total, 4 on the sticks, 1 is gear switch, and 1 you cant have!
now this is where I could do with the tx in my hand. You have 3 knobs, all of which offer proportional control, and they are used in heli mode, to alter the pitch of the blades (pit) hover throttle on the right alters the throttle pitch of a heli, and the other knob is another heli fine tuning. I reckon, you can assign 1 or more to a channel, but you will have to plug the servo in to remaining channel one at a time, turn the knobs, see if servo moves, if it does, bingo, you have another proportional channel. There isa alsao an aux channel, and I cant see where it is in the rubbish chinglish instructions.
It has some mix set ups, and has 8 model memory, so is quite good, but a tad complicated. You could always use the gear channel, and fit an inline servo slow (very cheap from the likes of hobbyking) so then the operation wont be fast on/off, it will be slow.
I'm sure it will give you what you want, but I think you will have to experiment, hope some of that helps
