I have made significant modifications to the Great Planes Avistar 30cc in order to make it a worthy tow plane.
The following posts will walk you through all the changes I have made and an explanation of why I did them.
For now, because I travel a lot and can't put this all together in a single post, I will leave you with a few photos and let you know that my plane has a DLE 55cc engine.
90" wingspan. If you are familiar with the large Avistar look at the size of the elevators. I added 3" making it a 5" elevator.
The landing gear is from the Bidule 111 and the wheels are Du-Bro 6" inflatable tires.
Adding 3 extra inches to the elevators.
