If you were going to buy 1 Radio transmitter to use with FE Boats and to use with RC Cars, which one would you buy and why??? I need some help here. I've got an 38" FE Hydroplane about half finished on my build table and I also have developed a huge interest in On Road RC Carpet Racing. I haven't purchased a radio or any electronics for either.

Thanks in advance,
