High Pressure Pete (oz2136)

About this Plan

High Pressure Pete. Control line model for .049 K&B Torpedo.

Quote: "A hot half-A stunter and some good advice on scaling down models for tiny motors. High Pressure Pete may be in the runt class, but he still boasts all the latest improvements in model aviation as well as top-notch flight performance.

Shortly after the introduction of A/2 engines, fellows in our neigh-borhood became interested and we built some small stunt planes. Performance was reasonably good but the engines were very erratic and would sputter and slow down during stunt maneuvers. Red Reinhardt's 'Roger Dodger' (AT March 1950) is a good example of this design trend. Inconsistent power made it necessary to keep the total weight between 3 and 3-1/2 ounces. The power plant weighed approximately 1-1/2 ounces with fuel tank, so the ship had to be held to 2 ounces.

To accomplish this, landing gear was eliminated and light frame-work was used with no sheeting on the wing, and the paint job was very skimpy. Performance was not good enough for contest stunt fly-ing and the novelty of small engines seemed to be the main point of interest. This wore off after a couple of months and we went back to larger engines.

Early in the 1950 season when new contest ships were taking shape, Jim Walker introduced his pressure regulator fuel system. Fuel supply has always been the greatest problem in stunt flying, so we tried a Walker tank in an experimental ship. The results were amazing. After we had learned a few tricks in installing..."
