Well, technology is developing fast, but one issue always remains: how to config the TX to allow 6 modes...

Here is a 6 modes switch for ANY Transmitter !

Enter for details

The idea is to have 4 trimmers to allow precise setting of the wanted PWM…

My daughters and I have built several quadrotors out of aluminum and also a mini quad out of kite parts (see beatty-robotics.com for these). But for this next project, we decided to make a quadrotor out of carbon fiber. We applied everything we learned on our previous builds and also tried a few new ideas that we hadn't tried before. …

These instructions explain how to set up a Spektrum DX7 transmitter for 6 different flight modes, using just the 3 position Flaps switch (in combination with the Rudder switch). This way you'll use just one channel for the flight modes and leave the Gear and Aux2 channel open ...

(note that you have to use…

This is how it worked for my DX7,

I use various switch combinations of the FLAPS and the GEAR switch which will give you 6 modes;

(note that you have to use the DX7 in "airplane mode", not in "heli mode" to fly a…

The T6EX doesn't have a 3 position switch channel, so I had to combine channel 5 and 6 to get four modes. I made it work with a pot that has double terminals for each knob position, so that way there is always 2 pins to connect cables to for a single position.

Think of this knob as a bridge between same terminals: A to A, B to B, etc, closing the circuit to ground.

Channel 6 is connected to a terminal A and a terminal B from the opposite side.

Channel 5 is…

This is just a quickie before I go to bed.

Those with a Futaba 6EX will know the toggle don't always feel right when you are flying a plane well as I use both my extra channels for mode switching I figured enough was enough and put them together. I took off the back and traced the wires back to a PCB point.…
