I don't want to flame or anything, but here a couple of suggestion for your guide.

«a car uses 2 channels, a plane uses 4 channels minium, These are to move four control
surfaces»

Some planes are made to be used with 3 channels, (well they existed last time i checked) LOL

also

«Here are the main manufacters of radio contol systems in RC Aircraft (in order of best/most use manu.)

FUTABA
JR
HITEC
SANWA/AEROTRONICS
GRAUPNER»

ok, what exactly do you mean by «(in order of best/most use manu.)»?
What is best? best quality to price, the most robust design, the most hitech, the better looking? Also, the list you've given, is it made from assumption or was it taken from somewhere else? If so where?.
Also, what kind of test did you use to decide which radio is the best, did you use equivalent models?

And what exactly does «most use manu.» means?
most used in the world, in the states, in uk?
then again, where are the facts? (was there a survey?)
Also, are they «most used» by beginners or experts flyers?
How did you compile the data from «in order of best» AND «most use manu.» to be in a single list? What scale did you use? 50%-50%?
I beleive that you should clarify a bit more.

and last but not least.
Again, it's pretty much the same critic with the suggestion of engines.
did you test them, or was it tested by someone, what method was used to test. what were the hypothesis, the independent and dependent variables to conclude that those motors were the best.

Also, you might want to add a section about the .40 vs .46 size engine to start out with. As you know, some modelers say start with a .46 since it will be more usefull in the long run and it cost around the same amount.

like i said, my intentions is not to flame or anything. It's just that being a social-scientist (in training) you start to really nit-pick on the small things that can make a big difference.

also, sorry for the grammar, the english language is not my native one.
