RCS insert launch config

This is a replacement for the fore reaction control system thruster module on the Monogram 1/72 space shuttle kit.  The thrusters ports are modeled as solid filled-in ovals.  Ths is to permit modelers to simulate the overlying rain covers used in launch configuration with decals.  Modelers wishing to simulate their shuttle without the covers, such as on orbit or at landing, should consider purchasing the RCS on orbit/landing insert model in my shop.
