talk to some combat guys, they might sell you a cheapo motor(youll find them getting rid of some fairly worn out ones sometimes(maybe fifty for a worn one) a spad could be had for about 25$.........a radio is only about 100$ new, . your still going to need a MINIMUM of about 150$ to get into it. My advice is to get about 150 or so together before you start looking and you might find a .15 size plane apropriate for you
