The S-300 possesses many of the attributes synonymous with today's world class aerobatic machines. The strongest asset of this exciting aircraft is its ability to turn seemingly square corners without any hint of stalling or buffeting.

I have been unable to make this aircraft stall in a pull or push, high or low speed, entering or exiting the vertical attitude. The aircraft has an in- credible ability to "hang on" at the top of extended vertical lines where the biplane has a tendency to settle and stall off the top.

As difficult as it is to stall the machine in a continuous "G" situation, the S-300 performs snap rolls with the flick of a wrist. The machine's vertical snapping capability (both up and down) is nothing less than phenomenal. Very little pitch change occurs along with an extremely rapid rate of roll which produces a very tight rotation with little energy loss.

The S-300 has vertical penetration comparable to most of today’s six-cylinder monoplanes. At “25 square” (75% power) on a 35 degree New England winter day, the S-300 indicates 2,500 feet of vertical penetration from an indicated airspeed of 220 mph.

Spins in the S-300 are predicable and conventional both inverted and upright.

This aircraft is an all-around docile machine both on the ground and in the air It is capable of competing in the world competition arena as well as in the lower categories on a regional level.

The S-300 is a superior homebuilt aircraft with a level of quality that exceeds most of today's factory-built machines It is a new and exciting American-built mono-wing that can be built for a price that is just slightly more than a new Pitts 8-2B (full equipped) with much more performance.

 (Editor's Note- The last report we received from the designer and builder of the S-300, Jon Staudacher ,indicated that a half-dozen examples had been completed or were underway Mike Goulian recently moved up to Unlimited category and competed at the 1991 US Nationals where he did a fine job of flying his new S-300.)
