if you go with a Herr, theire cheap and so are the engines, but like was previously said, you will need maybe $300 you cna do the plane itslef for $65-$70 then you are down the radio engine and field... but 200 could be done if you cna find some one with a old 4 chanel they want to lend/sell cheap to you. and scrounge up 4 STD servos as about $10 each.
