Since we are on the subject of the RV-9 450...... How much trouble would it be to change the covering or even recover this kit? My RV-9 paint scheme will be very similar but I plan to have yellow on top, white on the bottom and blue horizontal stripes and I want the R/C plane to match the real one. Should I remove all the old covering and start over for the weight savings or can I just cover what's already there with more ultracoat?
