Spektrum went really cheap with this transmitter, just look under the hood.
Something that always bothered me was that my DX6i did not have a gyro adjust knob, something even the cheapest transmitters from other companies have. Even the non-computer five chanel version of this radio has it (the transmitter that came with my Blade SR).
So I looked at a few DIY articles and videos and asked myself why are they doing this in such a complex manor?
All I really wanted today was a switch to control flight mode in Cleanflight.
So I did it, clean and simple.
Parts: DPDT on-off-on toggle
Tools: Philips #1, spanner(s) for switches, and soldering iron
Step 1: desolder and remove gear switch
Step 2: solder wires to DPDT switch, black to centre
Step 3: desolder yellow wire from ELE D/R switch
Step 4: solder yellow on third terminal of DPDT switch
Step 5: Install DPDT switch in GEAR switch mounting hole
Step 6: program mix1
your new switch is on channel 5
the switch will switch Left:Right:Centre, in that order
simply program your Baseflight or Cleanflight controller to suit
fwiw I use the FLAPS switch on the AUX channel to arm/disarm the FC
Sometimes I wish I was still living in my parent's basement and had loads of time for building models. (actually I never have lived in a basement)
HAHAHAHAHA no. I would not trade anything for my beautiful, intelligent and caring wife and daughter.
Not much time, as when I'm not a homemaker I'm making homes; renovating mine own and installing home automation in others.
I renovate anything between the basement drains and chimney, learned lots.
Formally I am an Electronics Technologist, and spent a decade designing and building test equipment and prototypes as well as conforming and touring UL, CSA and ESA around our plant. We built printers, big ones, really big ones. i.e. fill a 44 foot trailer, 50kW, 2000 pages per minute...
