Expansion of the Taranis Pistola: A pistol grip RC controller

I think the Taranis Pistola by Eficker is one bloody brilliant idea. Not just for those of us who don't get the hang of driving surface vehicles with sticks, but as a system to replace most other pistol style transmitters when it comes to channels and fine tuning options.

The original design is only lacking 3 things that I am trying to add to it.

1.) Support for the 2nd Gimbal
2.) Having the 4th trim rocker switch
3.) being able to use the JR Mo
