This is the "Visitors" Skyfighter that was used in "V" The Series (The Original Series).
Designed by Thunderchild.
This kit contains all of the parts to make the Skyfighter, the Troop Transport, and the Cargo Transport.
The interesting thing about this model is that you can use magnets to hold the different sections together. So all you have to do is build the one Skyfighter and the different pod (both troop and cargo) and change them out how ever you wish.
