How to turn using just turn stick with throttle off!

I just completed posting a mod over at RCG and thought I would add it to this thread as well.

Here is the mod. It involves switching power back on to both motors while also switching on the turn. This stops the chance of the model going into a spin.

Parts.
4 pieces of thin insulated wire 6" long.
2 conductive lugs ( like the leg of a 10W resistor - something a little strong).
A piece of flat steel, like a spade connector end.
A piece of springy steel - like a coin battery retainer.
A small flathead scew.
Some CA and solder.

Prep.
Remove the antenna and 7 retaining screws and open the txer.


Step1.
Here we are going to make a wiper arm assembly on the throttle stick.
Disassemble the throttle stick by first unscrewing the 2 retaining screws of the back panel and then the single screw holding the stick to the cct board.
Cut a small piece of the end of the spade connector type material so you end up with a rectangle about the width of the throttle arm. Solder a piece of wire to the side/edge of this.
Cut out the same amount of plastic from the base of the throttle swing arm to create a recess and superglue the piece in place.





Get your springy steel arm and bend it around from the bottom of the throttle main assembly so it forms contact with the rectangle when it is in the off position.





Solder a piece of wire to the end of this that sits on the bottom of the housing and then drill and screw it onto the bottom of the housing. Put the housing back together.






Solder the other end of the wire from the bottom wiper to the 2nd pin down of the 4 solder pads you can see next to the stick assembly.
Solder a piece of wire to the 4th pin down of the 4 solder pads you can see next to the stick assembly. Remount the assembly back on the cct board and then in the txer.





Thats that done.


Step2.
Here is where we mod the turn stick. We are going to mount 2 small lugs into the assembly and use the spring as a conductor.
Disassemble the turn stick by removing the 2 retaining screws of the back panel and then removing the housing screw.
Align the tension spring that holds the turn stick in the centre so it is sitting true and mark about half way towards the tip of each arm where the lug (resistor leg wire - something a little strong) will get touched by the spring if it is bent out by the stick. EG - while resting, the spring wont touch the lugs - when you turn left or right the spring will touch.
Drill 2 holes and make it so it will be a snug fit for the lugs. Solder a piece of wire to each 'lug' and push through the hole for each one.





Get the piece of wire that was connected to the rectangular steel wiper part of the throttle arm and after tinning the open end, wrap it around one end of the Return spring arm and squeeze it with small pliers to get a good contact. Put the spring back in place and slide the wire up to the very top of the spring arm. This gets it out the way of anything.





Put the assembly back together.





Mount the stick back in the txer.





Step3.
All we do now is join the 3 open ends of the wires left and we're done!
Grab the two wires coming from the turn stick and the wire coming from the 4th pin on the throttle cct board and solder the ends together. Insulate the join with heatshrink or tape.






Test it to make sure it does power up when moving the turn Stick left and right and then put the Txer housing back together.
