Nice job, Wayne
We call those planes the Southeast Missouri Air Show. From Early Spring to late Fall, you can see one or several almost all of the time during "agricultural aerobatics". They have GPS to find the field they are spraying, turboprop engines swinging 4 bladed props and they haul 800 gallons of spray (over 2 tons). They are more sophisticated that the military air forces of some countries.
The Akromaster is a great design for kit-bashing! Its big brother, the Twister is, also.
