Valuable air filters are easily lost, e.g., in nose-over landings. To eliminate the expense of replacements, pierce a hole in the lining of the rubber cap, then twist fine copper wire through it and around the idle screw. Now it may pop off, but it stays with the ship. Adapted from 400 Great R/C Modeling Tips by Jim Newman, Volume II, an Air Age Media publication.
