i asked a couple of friends that fly and they all learned on nitro. they said it was easier to learn on them cause of their big wingspan. plus if i buy a plane with ailerons now i wont have to make them and put them on later.
Did you ask your friends if they learned by themselves? If so how many crashes did they have before becoming proficient enough to leave the field with the model in the same condition that it arrived in.
You make several statements that need to be addressed before you pick a plane. The most critical to your success is are you going to attempt this without experienced help. If you are I would stay away from standard nitro trainers for several reason the two most important are.
1. Speed
The average .40 sized nitro sized trainer will fly 30-50mph with no problems (That means that 13 acres is going to seem pretty small to you at first) The speed coupled with your inexperience means that you are going to have little or no time to react before your plane gets far enough away that you won't be able to clearly see what it is doing as a result of your actions (i.e. is it banking left or right is it flying inverted or up right.)
2. Properly breaking in/tuning your engine and trimming your plane.
A lot of beginners get on these forums and assume that they are going to take their new ARF/RTF pride and joy out of the box start it up and have it operate and fly 100% correctly right out of the box. Unfortunatly this is usually no the cause. Running an engine to lean can damage it Running ABC/ABN type engines to rich can cause premature engine wear. Flying a plane with an engine that doesn't idle or transition properly can cause the engine to "flame out" forcing a dead strick landing at best and a crash at worse. Flying a plane that is badly out of trim and or balance can be difficult for those of us with experience for a beginner it usually spells disaster
Please under stand that I'm not trying to discourage you only attempting to point out that if you are on a tight budget you should make decisions and pick equipment that will minimize damages to your model causing you to either quit the hobby or spend more money then neccessary.
Having flown both Nitro and Electric. I would strongly suggest going the electric park flyer route if you are planning on learning unassisted.
