I'm glad you've come along Walter. I believe your company came up with an excellent product at a time when it was needed and gave the engine manufacturers a timely shove.
Perhaps you can answer a question: do you believe it is possible to teach anybody in as little as 2 mins to safely operate a carbureted engine LOP; without limitation on altitude or power, and without engine monitor, using only seat in the pants feel for the "big mixture pull"? As claimed by your Australian colleague.
