Both Fei Bao and AirWorld make MiG-21 kits. The AirWorld is larger (2.78m long) than the Fei Bao (2.50m long).

Vin Difabbio (RCU username: Vincent) is our resident expert on the MiG-21 (he's had a half dozen or so of them including the AirWorld and FB kits). Perhaps you should PM him.

Here are links to the kits:
