Thanks Charlie,
Yes, It will make more sense once I start assembling those retracts I guess. I'm just trying to get the Tx setup for now. Make sure everything moves & centres the right way.
That Turnigy radio cost about $80 from Hobbyking. I was a bit sceptical at first but I opened it up and all the soldering, pads etc looked pretty well done.
Then I added a programming board and updated the software with this er9x and it is an extremely powerful 9 channel Tx. The Frsky module with telemetry Rx works great too.
To be honest though, I'd rather be flying than tinkering with programming a Tx all day ! Once it's all setup I shouldn't have to touch it again.
