RE: Where have all the deltas gone?
All joking aside, I have throttles on everything larger than .074. I wire the carb open on some of my Norvels just to save the weight and bulk of a throttle servo and linkage. I've passed up good deals on Nelson Q-40 motors simply due to their "all-or-nothing" nature. If I had my own private 1000 acre field, I might feel differently. Alas, I do not.
