Eduard re-released the very nice Mig-21MF kit in an awesome dual combo box of the MF in Czech and Czechoslovak service (39 marking options!) and with it they also released the overtrees of the kit and the Photo Etch (P/E) set (for an additional $14.95 - price above is only for the kit). If you have the Dual kit or even the older Profipack kit the overtrees are a nice and inexpensive way to add another kit. You get all of the plastic that comes with the kit but no instructions (No problem as Eduard has them on their web site) or decals (Again no problem as the Profipack and dual kit have many extras). As far as the interior goes, no problem, you can still get Eduard P/E for the early or late variants.
The plastic is grey in color, molded well with little to no flash and no noticeable sink marks. The clear parts are also very nice and extremely clear. The P/E set for this boxing deals mainly with the cockpit but there are a few other items also (For the landing gear, antennas, air boom, static dischargers, etc, etc.)
