Another question I have is everybody's thoughts on switching a receiver between multiple planes.
You can do it but it is not as simple as it was in the old days.
In the old days you carefully set throws, servo directions, and Differential mechanically as there was no programmable features in the radio system. If you needed to apply trim you would adjust the plane to allow you to re-centre the trims. Thus any Rx would function well in your plane.
With modern radio systems if you want to swap Rxs between planes then you will effectively need to reprogram the Tx each and every time. You will need to know what the Tx settings you will need for each plane and which servos need to be reversed.
I tried it for a while and quickly realized that it was NOT for me! I go to the field to fly not demonstrate my skills at setting up a plane from scratch. Some of my planes have rather extreme settings and if I was to forget something I could have a disaster very quickly. Currently I go to the field pick a plane fit a battery and away I go! But then I do have a separate Rx for each plane I fly!
Just my opinions of course!
Have fun!
