Believe me, I've "been there, done that", and the only way to do this right is to do it the right way. You will benefit in the end.
The piece you need is "Yuneec USB Interface/Programmer: Q500 YUNA100". I just went on eBay, and there are several available. The site sponsor might have them, Amazon might, maybe even a local hobby store.
