That being said, you can purchase [link=http://www.horizonhobby.com/Products/RelatedParts.aspx?ProdID=EFLH1031&Category=Used%20 In...&SubCategory=]EFLH1031[/link] and use it just as mixer, gyro and ESC, then hook up your own receiver. I've done it to my blade cp with Spektrum technology.
I got mine from myrcsupply.com, and here is a link to it. [link=http://myrcsupply.net/index.php?main_page=product_info&products_id=10928]3 in 1.[/link] A bit cheaper than horizon. I encourage you to always check out prices from places other than horizon.
Hope that Helps!
