The 4-channel radio that come in th RTF pakage deals are not bad... Value of the radio system is a bit over $100, and is mostly in the servos, RX and batteries. The cost of an average airborne pack deal for putting in a second plane (to go with the 6 ch computer radio) costs right at $100... so there is no "loss' to buying the RTF with the 4 Ch and then getting the 6 ch later. It just splits some costs up differently.

The engines typically put in the RTF packages are usually better than the cheapest onthe market... though they are not the best... they can give several years of service. Again... not a bad deal. I even buy equivilent engines on purpose. (O.S. LA, Magnum XL, Tower brand engines...) They work fine and do what is needed.

There is no reason to add the confusion of the computer radio when first starting out. The basic 4-ch will teach you to properly set up the linkages on the model. The computer radio could let you develop bad habits that would later come back to haunt you. If yo stick with the hobby, you'll want the second flight pack... so... start with the cheaper radio.
