hi, i have been using a hitec zebra 3 transmitter for controlling my rc , twin motor/twin esc baitboat but it has developed a fault, so i bought a hitec laser 4 to replace it.
my problem is setting the transmitter up with my boat, i need it to control forward and reverse from left stick and left and right from right stick and allso control one servo which is conected to a door release.
at moment it is not doing this, left stick up and down controls servo (which is in ch3 on reciever).
right stick controlls motors, up and down for one side and left and right for other.
i want it to react as follows,
left stick up = both motors forward
left stick down = both motors reverse
right stick right = left motor forward and right motor reverse(to turn right)
right stick left = right motor forward and left motor reverse(to turn left)
this is how my zebra 3 worked the motors but cant seem to figure out how to get the laser 4 to do the same?
i am a complete novice at r/c so any help would be much appreciated, thanks, jay.

I think you may want to incorporate a mixer into your control system.
Otherwise you may run the risk of shorting out your ESC. [:@]

Personally, I would just run it like a tank.
One ESC for each up/down stick.

Push both sticks foward, both motors forward
pull both sticks bac, both motors back.
One stick fwd and one stick back would run either motor as directed.

Then use the left and right motion on either stick to release bait, or your line.

thanks for your reply, i tried it  "tank style" and it works fine !
when connecting it like this am i right in thinking i dont need a mixer ?
cheers.

Yes, it should run fine "tank style with no mixer.
Each ESC runs from the battery to it's own motor, so there should
be no chance of any shorts between them.

You do the mixing yourself using the sticks.
