A foam parkflyer adaptation of Laddie Mikulasko’s beautiful Northstar seaplane.
Designed by Steve Shumate.

This model handles BEAUTIFULLY both in the air and on the water, and is a real joy to fly. It’s well-mannered, smooth and stable at all speeds and aerobatics are a breeze, but to me one of the best things about this model is the amazing speed range—top speed is in excess of 70 mph, yet the model slows down well and can plop down into the water at high alpha under full control at less than 10 mph. This allows the model to be flown in very tight spaces if desired, or if you have a bigger flying site you can open it up and enjoy the speed. It handles wind and waves remarkably well, too. This model also flies very well off of grass—takeoffs require only 10-20 feet and it can even do easy touch and goes off grass.

For those that want to save time over scratch building this model, a complete laser cut kit is now available at Model Aero. Here’s a link:
