| One way to do it with the 8103(3810) is to use the pitch trim knob on the front of the transmitter next to the dual rate switch there.
I would suggest that you copy your present model to another slot and "tweak" on that one, that way if you get it all messed up and forget what you need to go back to, all you have to do is reset the copied model and you haven't messed up your original. After you get it all working the way you want it you can then go back and change your original model knowing that it will work and you can "reset" the copied model.
1. hold the up&down(mode) buttons down as you turn the transmitter on it is the same screen where you change models.
2. scroll to and select the "input select" choice
3.change the screen till you get Aux2 as the channel that is controlled by the pitch trim .
This will allow you to use the pitch trim knob to control the servo attached to Aux2. You can adjust the ATV's of Aux2 to get the throws you want. Obviosly you need a reciever with Aux2 available, a 6 channel reciever won't cut it. Instead of using loctite on the 2.5mm screw holding the dubro arm onto the needle I use a pair of nord lock washers. This allows me to loosen the 2.5mm screw and recenter the servo if I find that I have to make a large adjustment as is sometimes needed when the seasons change here in the northeast. I have them installed in a R-60 and R-50 and since I mounted the tail servo on the boom on both heli's I use the stock tail rotor servo location and a futaba 148 servo. No more walking out to the flight line and stopping the rotorhead with your hand and then adjusting. I just fly straight & level and reach up and give her a few clicks in the direction that I want. Note that it is best to use your servo reversing on Aux2 to get your pitch trim knob to operate in the same manner as your needle valve, that is , a clockwise turn of the pitch trim knob will lean the mixture and a counterclockwise turn of the pitch trim knob will richen the mixture, otherwise you can get confused in the air and adjjust it the wrong way(not good).
