The Mirages you were watching in South Africa are Mirages F1, which are really different than the 2000.
The F1 's got a high swept wing with tailplanes whereas the 2000 is a pure delta aircraft.
Anyway AD's small Mirage has obechi covereded foam wings.
I saw one fly with a JPX engine but it was really to heavy for that small wing
Ram500/MW54 would be ideal for this bird.
