Like a lot of folks I like the "Stik" type models especially for a second plane. A Great Planes big stick 40 would work for a second plane and can be set up for easy trainer type flying or with the throws increased will do all the basic aerobatics. Another good choice if you don't want the Stik look is great Planes Easy Sport 40 ARF. I just put one of those together and its a fine model. Easy on low rates and a real stunter on high rates. I changed mine to a tail dragger set up. An easy mod to do. Here is a couple of pics.
