if its looked upon as two different hobbies, then i share an equal interest in both. as far as the cost factor goes, building this kit and buying the arf are about the same in price. the arf, which costs about $200 plus $240 for the hitec 7ch eclipse radio and glue to assemble the arf comes to around the $500 mark. where the kit only costs $83, plus glue, covering (about $75) and the $240 for the radio puts it at about $500. i still have the wheels, fuel tank and other misc items from my other airplane.
