na - I just spend too much time fiddling with it (rather than flying) as I find it fascinating!
To make a simple ship with dual rates there is not too much to it and companion makes that programming a doddle - the complexity creeps in when you want to customise the radio to your liking which adds another level of functionality at your disposal (like logical switches, in-flight adjustments, and voice calls for modes or values), but the more you get into it the easier it gets.
There is heaps of great OTX instruction and tips on youtube but I started with this 'basics' overview from
RC-soar and poked around youtube for the rest - just the other day I learned about the 'instant trim' command in OTX which enables you to hold a level flight path and grab the trim settings at the push of a button (nice!) - so we learn new things each day!
I knew nothing of programming when I started out - if you keep things neat - especially the mixes using the cascading technique of combining common trims into sub-channels you can't go too far wrong!
The examples below illustrate the idea of cascading - channels 12/14/16 are trims that affect both ailerons so I can set up and tweak these settings once and apply them to the ailerons by attaching the grouped channel 18 to each aileron (neatly) - although channel 10 only effects the flap channel I cascade the trim settings for neatness and easy visibility for tweaking the settings rather than trying to do it within a growing list of mix settings within the flaps channel.
As a side note about channel 8 for the expo, this weight and offset amount will make a global variable for the expo vary between 0-50%, and in OTX the weight is worked out by using the total variable (min and max) where in this case the min is 0 and the max is 50 - the weight is calculated (max-min/2) and the offset is calculated (max+min/2) - therefore the weight is 50-0/2=25 and the offset is 50+0/2=25
I am happy to help (try to help) if you have any tweaks or modes you want to create.
