Default Flying in reverse (apparently

I am kicking around the idea (challange) of trying to build an RC plane that flies backwards. My simple vision is to have a plane that on the ground, looks exactly like a basic trainer but when powered up heads down the runway in reverse, flies a basic pattern and lands safely. This trick should have a pretty nice WOW factor.

Has this been done before?

It seems to me that the real challanges are:
1) getting the main air foil to generate adequate lift when operating backwards relative to air flow.
2) building in sufficient stability to keep the plane in the air and get it down at some reasonable speed.

Obviously this design challange is not about efficiency it about getting it to work. My first thoughts are to focus on fiding the right angle of incidence of both the main wing and the stablizer. While I don't want the planes profile on the ground to be abnormal modest amounts of positive incidence would likely not be noticeable.

I'm just a dumb old RC model fan with no particular training in aerodynacs (obviuosly) who likes a challange.

Any ideas on how to make this happen? Can't be done is not an option.

Thanks for your thoughts in advance!!!
