Years ago I purchased some Federal 1500A skis for my Cessna 140A. However, they plow the taxiway and runway too quickly to use straight skis. Without spending the 5K+ for wheel penetration skis (Trickair), I was thinking of building / buying ski dolly's but am not certain if you can taxi on them as the usable grass median is about a 1000 + feet from my hanger.
