The first three models to be built and flown were gathered together at the 2019 Horizon Aerotow Event in Muncie, Indiana in mid June' 2019.
Peter's prototype is in the background on the right-hand side and Len's (which was the first kit to be finished finished) is in the background on the left-hand side. Our model was the first to be built with wing mounted landing gear and the added outboard flap section. It is picture here in the foreground.
Some interesting notes about the similarities and differences of these three models.
All have DA-150 engines and DA stock mufflers. Peter is running a 2-blade Mejzlik 30x12 carbon prop while Len and I have 3-blade Mejzlik 28.5x12 carbon props.
Peter's DA-150 is the older heavier version while Len and I both have the newer lighter versions. This, as well as a change in the tail sheeting thickness Peter made after his prototype, resulted in Len and I having to add nose weight to achieve balance.
Subsequent to the initial flights (which were fine), Len elected to extend his motor mount forward and thereby remove the ballast weight. If you look closely, you can tell his cowling is longer than those on Peter's and my model. I added about 1.25 lbs. of weight to the inside front rim of the cowling on my model to get it balanced.
Peter's plane uses the Horizon Hobby Pawnee landing gear while Len's model has a 1/4' thick aluminum landing gear. As mentioned earlier, mine uses custom length wing-mounted Robart Struts that required a 4" insert to pre-load the strut springs.
