Got a Piper PA-18 Super Cub? If you do, the STC for a sizable gross weight increase that’s been in the works at CubCrafters is good news, especially if you want to carry floats and more payload. For eligible PA-18 Super Cubs, it’s a substantial jump.
The STC increases the certified gross weight from 1750 pounds to 2300 pounds. That’s more than a 30 percent increase in payload capacity. Float-equipped aircraft owners will also find this STC appealing, as the increased legal useful load makes it feasible to comfortably carry two people, fuel and bags—something often difficult or impossible under the Super Cub’s previous weight limits.
