Get the 2.4. I'm only three months into the hobby and I'm looking to get my third plane. I'm stuck with 4 channels, and I'll be forced to use a Yharness for dual aileron servos (which isn't a problem). I suspect, though, that by the end of the summer I will be looking to buy a more advanced plane, and a 4 channel radio will not be sufficient. Witht that being said, my 72 has worked perfectly, and there is nothing wrong with them. Ultimately, though, you'll be in the market for a better tx, so you might as well make the investment now if you can. GL!
