Since you list ARF trainers I'd go with the Hobbico or Sig LT40. They are built better than the other ones listed. I have been instructor for the last 3 summers. All trainers are not the same! 2 of the ARFs you mentioned contain a lot of plastic in the fuselage instead of balsa. This is very hard to repair. Ground handlying can very from very stable with almost no bounce to bouncing up and down off the runway as you taxi. Learning to land is the final lesson that all the previous lessons are leading up to. The LT40 just has to be guided in straight and level with the engine at an idle and it practically lands itself. It also turns into a large glider if the engine leans out and quits making it easy to get back to the runway. With a good engine like the TT46 Pro you can hang on the prop at 1/2 throttle and do torque rolls. On the radio, I would just get a basic 4 channel for now. You will have enough expenses while learning without adding a radio that will add more confusion than you need. You can always use it down the road for training or another plane. Newbies think its cool to have dual rates ect. Trainer boxes only go to what ever the high rate is set for. If you have high rate set for 110% and low rate at 80% the buddy box will operate at e the 110% setting which may be too much for you and the plane! The next 2 channels after the basic 4 are for flaps and retracts. Unless you have a very smooth field the retracts may be ripped out on the first landing! Flaps are needed on larger heavier planes which means that, uless you rush things you probably won't be having a plane like that any time soon. Model memory isn't needed on 4 channel planes that are set up so the servos are all moving the same direction for the same stick movement! I have 5 planes set up this way. Just make sure that the transmitter matches the brand of buddy box at the club. That why I suggest visiting a club before you go out and buy anything! Fast!
