For the subject of this setup session, we used an F6 Marblehead fitted with a Stinger Winch (with the built in, onboard throttle curve) upon which we have a 32mm drum.
It is best to do the transmitter set up for the swing rig as it has a longer mainsheet ‘throw’. When you have it working perfectly, we suggest then duplicating the swing rig model to form one for B Rig and one for C rig. Then rename the duplicate models properly so you dont get confused. Upon the B and C rig models you mainly just have to reset the end limits… though one or two small adjustments might be needed to get your preferences for sheet measurements precisely done.
TIP: On mainsheet/throttle/CH1 end limits we need a fair bit of space at each end of the spectrum – sheeted out and sheeted in. The way our advanced features (joystick pinch, double puff switch, VMG fine tuning) work is that they tend to focus when you are sheeted in. The transmitter pumps out a reading from the joystick, then the advanced features act as a multiplier on whatever the mainsheet reading is. It is quite possible that on one of your rigs you find you move the end limit to zero to get the sheeted in position properly. When the mixers multiply the mixer settings with zero – you still get zero. Nothing seems to work!! So you need to fiddle and get a decent end limit number when you are sheeted in. A quite possible solution is changing your mainsheet/jibsheet lengths on their bowllies – or if you have to, pop a new mainsheet/jibsheet on with the needed length..
On Spektrum, adjusting your End Limits is blissfuly easy. Select the servo setup menu and scroll to the “Travel” page (see below). Now sheet in on your left joystick, get your deck ruler out to help adjustments.
You will see that on the boat in the workshop I have needed to set my limits at 75 and 60 to get the limits that I want to see.
As it turns out, the rudder is giving perfect measured 45 degree swing, so I have left those limits at 100 each.
Press “back” to save your settings. You will likely return to this menu quite often.
