That 6EX you have has the capability to store the information of up to 6 planes, which means you can set up 6 planes and set the trims, and it will remember them all, so all you have to do is name the plane on the receiver, then select it when you want to fly it, and not have to set any trims. It has plenty of mixing capabilities for when you advance, and has the option of having exponentials set on the throws, as well as two settings, (high and low?) for response.

It will keep you occupied for a long time. Enjoy it!
