Electric airplanes made of molded foam are very popular in the RC world right now. While this class of airplanes used to be limited to small models with modest power, there is seemingly no limit to the size and power handling of modern “foamies”. Perhaps the largest contributor to their popularity is the marginal effort that’s required to assemble an attractive and nice-flying foam model. There are, however, some things to be aware of, and habits you should develop to court success with these aircraft. I recently assembled and flew a newly-released foamy to illustrate what I’m talking about.
The Flitework Stearman
The model that I used for this article is the Flitework PT-17 Stearman. It is a 1:8 scale model of the 1942 Boeing PT-17 that is owned and flown by The Flying Bulls in Austria. Most of the model is constructed of molded Expanded PolyOlefin (EPO) foam, a popular material for RC planes. This is a Receiver-Ready (RR) model, meaning that all of the control servos and power system components are included and installed. The user must provide a radio receiver and transmitter, as well as an appropriate battery to power the airplane.
This was my first experience with a Flitework model. Overall, I would consider it a little above average among the current crop of RR foamies that I’ve seen. The mold quality of the foam components was excellent and the finish applied to the airplane was well executed. There is nothing worse than factory-applied trim schemes with sloppy paint overspray or crooked decals. I was happy that neither sin was displayed here.
Despite my positive first impressions with this model, my unboxing inspection also revealed a few common shortcomings that I would need to address. The positive side of this is that the corrections were easily implemented and didn’t incur any extra cost. As I outline the basic assembly steps, I will cover those changes, as well as some tips and tricks that may not be intuitive.
