Foam Techniques: Part 2
IN LAST MONTH'S installment, we covered foam as a material, types of foam, chemical characteristics, compatible solvents and glues, etc. This month we will cover the construction and safe use of cutting bows, power supply, and the techniques of cutting various types of wing cores. Next month's installment concerns covering and skinning and use of compatible adhesives, and finishing. Cutting Foam You can easily equip yourself and master the techniques for cutting your own foam cores. The following equipment is required.

TIME WAS WHEN a good sport model and a pattern were synonymous. One does not have to go back very far to remember when the Taurus was a great Sunday flier as well as the last word in pattern. But year by year the 60-powered aircraft was bred into a highly refined competition machine, the steady stream of refinements making it rather specialized and expensive for casual aerobatics. Does the aerobatic sport pilot need such a ship? The answer would seem to be no, especially since the recent increases in cost of big engines and fuel alone have made the 19- to 40-size airplane so attractive. Ever since more powerful high-reviving engines have been on the market, the need continues for a racy looking, simplified, compact aircraft whose maneuverability is appropriate to these powerplants. Hot Rock meets this challenge head on. It's name, incidentally, derives from gungho World War II fighter pilots who flew as if there was no tomorrow.
