Have a look at the GP Ultra Sport 40+. It has solid flight characteristics like the Aresti, but has a BIG clear canopy which you could easily build a camera mount under, and it has retracts so once it picks up it's feet it should be a real zoomer.

There is a very long thread in the "Kits" forum on this plane and the one flight review that is there is very positive, indicating that the plane is very solid in the air.
