If you are on a limited budget, a 4 channel will work just fine.
I agree, however the decent 4ch transmitters I have looked at don't seem to differ in price from the likes of the budget 6ch's by a great margin. Maybe I'm just looking in the wrong places.
So if the prop dosen't come with the plane does it come with the motor? If not, what do I need to consider when buying one?
Futaba 4YF with 4 S3004 servos $124.99 minus $20 gift certificate (may only be $10) = $104.99
Futaba 6EXAS with 4 S3004 servos $179.99 minus $20 gift certificate = $ 159.99
To me, this is a fairly significant difference. When you say budget 6 channel, did you mean non-computerized? If so, save your money. Other than 2 more channels, there's little that you get from these that the 4 channel doesn't have. If you are going 6 channels, go with a computer model.
The prop does not come with the motor either. What you need to consider is the size and power of the engine combined with the style of flying you want to do. If you take an engine and put it on a trainer it will use one size prop. Put the same engine on a speed plane and you will want an entirely different size prop. When you are looking at prop sizes, the first number is diameter. The second number is pitch. The pitch is the (theoretical) number of inches (milimeters) the prop will move forward for every revolution. On a trainer you would want a larger diameter, lower pitch plane. This is like being in a lower gear on a car. On a speed plane you would lower the diameter and raise the pitch so it will go faster.
