RE: Second plane
I have an e-flite Advance. It is an inexpensive Arf for 25 or 32 size electric, and it handles much like a four star.
Mine has the 32 motor and runs on 4 cell 3300. I think using the 25 and 3 cell would be the better way to go, since you would save considerable weight.
I also converted mine to tail dragger, but unless you are ok with opening the fuse, I'd leave it tricycle.
