that is what i did, except it flies with 1 motor completely forward in a cross shape, not in an x shape. it would require a LOT more mixers to do it that way i mixed the controls on my futaba 8u but it did not have enough programable mixers to allow for rudder control. to be really honest, it will cost you about the same to make on as it will to buy one. because of the lack of mixers (evne on the 8u) i had to use vtail mixers. with that im mind, i have about $550 in the flyer itself and another $200 in radio so it adds up to about the same. if you want to make one, i will be happy to help with sugestions and such. if you have any questions you can ask me if you wish, i would be happy to help. here's a pic of mine flying
