Murphy Radical
Murphy Radical is the culmination of 39 years of aircraft design and building experience.
The Aircraft
The Radical is a very roomy two seat bush plane. Even the largest pilots will find they have plenty of head, leg, and shoulder room. No need to be a contortionist to enter the Radical. The two large up swinging doors make it easy for even the less mobile to enter.
Design Philosophy
It has been designed and built to be a true rugged STOL bush aircraft incorporating the best ideas and design practices of all the Murphy aircraft.
Performance
You will not find another aircraft with the performance and usefulness of the Murphy Radical. Wheels, floats or skis, your adventure awaits…
Usefulness
Although tandem seat aircraft based on the original Piper Cub are very good performing aircraft, they do have several drawbacks. Many have reasonable useful load capabilities but when flying two up the space available for load carrying is very limited. This is not a problem with the Radical. The side-by-side seating leaves a cavernous space behind the seats available for load carrying.
The space is so large two can sleep comfortably on the double floor. No longer will your flying partner have to sit in the trunk. With the side-by-side seating they will be able to sit up front where the action is with full access to controls and instruments.
Construction
Like all Murphy High wing designs, aluminum was again chosen for the Radical. The benefits of aluminum sheets are just too many to ignore.
-EASY TO ASSEMBLE
