I would recommend that you build the Spadet or Debonair trainer. Either of these will be easier models on which to learn than either of the others that you have selected.

A simple four channel system, like the Futaba 4VF, will fulfill you needs easily. When you buy the radio, it will come with the transmitter, receiver, servos, batteries and charger, everything you need as far as radio. The standard servos will handle the loads of the average .40 size model. You won't want to build a model that will require to buy additioinal micro servos in order to get it in the air.

The instructions for building the Spadet, my preferred SPAD trainer, has basic instructions with pictures on installing the radio. If you have questions when you get to that point, you can ask them here so that the questions can be detailed rather than general as is required at this point. No offense, but I don't think you have the knowledge to ask your particular questions at this point. To answer your general questions will take a significant amount of writing.

When you move further along on the decision making process, you can post what you have decided and get opinions on your choices. Take it one step at a time rather than trying to get a total answer from a couple of general posts.

Good luck,
