Looks like I am quite sure what trainer I want. The 49" WS Rascal with a .049 to .07 glow fuel engine or a 70" ws 40 size rascal with a .40 or higher glow engine. Since I personally like smaller planes the .049 size rascal is my favorite, but Does this come as an ARF?...since at tower I only saw 40 size as ARF

Comparing .049 size rascal with the .40 rascal , which will be a better trainer with respect to:

controls, acrobatics (or is it aerobatics -whats the diffference??), flying time, noise, overall cost, hand launching ability, Take offs and landings in grass, safe landings every time,does 049size have ailerons? and Importantly min AIR SPEED to stay airborne in level flt?

I am gonna decide on the arf plane 1st , then worry about the radio.

If any of you could answer these I 'd apperciate it...Thanks!
