I learned on the firebird outlaw and then went to the slow stick. I do agree with rumme you do break props on the slow stick i think i have broken two or three ,but that is partly because of my flying field and flaring to early on landings. I haven't flown the T-hawk so i can't say which one is best. RTF's are easier to built and get in the air ,but i had my slow stick ready in one afternoon. If you get the slow stick make sure when you check the CG(center of gravity) that you make the slow stick a little nose heavy.
Have fun picking out your first plane,
