Gross Weight Increase to 2000 Lbs on a PA-18 Super Cub

Are you tired of watching your weight?
Want to keep your insurance in effect?

Here at Wipaire we have a modification which will allow your Cub to increase its total gross weight to 2000 pounds. This works for landplanes, seaplanes or amphibians equipped with Wipline 2100 floats. The increase to 2000 lbs gross weight is now approved with Edo 2000 floats.

The kit weighs less than 2 pounds and takes about 30 hours to install. If you are building up a Cub, make sure to install it during the process for time savings and higher resale value. Call us or fly-in today to learn more about this exciting product that is sure to enhance your investment and your total flying experience.
