Stan Burak 1/4 Scale Plan Ted Smith Aerostar
SKU: SAB:AS14
- Wing span: 110"
- Engine: Twin 35cc Gas
- Weight: 37 lbs
First a little history. It is not a Piper Aerostar! It was built by four companies, Piper being the last, ending about 1984. A total of 1010 built. Ted Smith was the project engineer of the Douglas A-20 bomber in the mid 1940’s. He got some guys together and after work they designed and built the Aero Commander. Kind of a smaller version of the A-20 and they sold it. Then came the Jet Commander, a mid-wing, swept tail, lengthened fuselage, jet powered Aero Commander. Ted left Rockwell in 1963 with the Aerostar idea, a shortened fuselage, swept forward wing version powered by piston engines instead of jets, based on the Jet Commander. Ted Smith Aircraft Company was established in the beginning of 1965 to design the structure and produce the proto type. I was employee number 7 designing structure. I left in 1966 to fly for TWA. I designed and built a wood and composite homebuilt while at TWA. This model uses my knowledge of the real aircraft and design and building my homebuilt. The Aerostar is about the fastest piston twin even at more than 50 years old. Ted wanted it fast and used the low drag 64A212 airfoil, no twist wing and no side or down thrust for the engines.

Product Description
This model uses my knowledge of the real aircraft and design and building my homebuilt. You will notice I use real aircraft materials, spruce, foam, epoxy and balsa. I used programs to calculate the wing spar and servo requirements at 75 mph. The main spar is good for minimum of 15 G’s at a wing loading of 32 ounces per square foot and 10 G’s at a loading of 48 ounces.
The Aerostar is about the fastest piston twin even at more than 50 years old. Ted wanted it fast and used the low drag 64A212 airfoil, no twist wing and no side or down thrust for the engines. I use the same 12% airfoil at the cost of a heavier main spar.
The model is not easy to build, because of the center section having to be built in. Below the center section has the gear retracting into the fuselage, AND above are windows.
