|
| (...) You have no need to apoligize. Your way of understanding is completely valid and brings to light many new ideas way outside the scope of my thinking and that of many others, I'm sure. I believe I do understand your explaination. So, it makes (...) (21 years ago, 5-Jun-03, to lugnet.technic, lugnet.robotics, lugnet.build)

| <snip> (...) You don't get very good speed control. I'd think that using the small range between completely off and completely on for one of the ports of a switch would be a better speed control. In the parially on state, you'd get constricted flow. (...) (21 years ago, 5-Jun-03, to lugnet.technic, lugnet.robotics, lugnet.build)

| (...) That hovercraft is excellent, and I like the use of fairings for a propellor. It looks fairly powerful, but I suspect it would produce more radial pressure than linear thrust. Thus no good as a propulsive device. The film used for the skirt (...) (21 years ago, 5-Jun-03, to lugnet.technic, FTX)

| (...) Well, that hovercraft uses a large non-LEGO film for the skirt. (...) So, okay, you're saying it's EVEN DENSER and less likely to fly. (...) It is if you're using LEGO for the wing. It's not if you're going to use some other material. (...) So (...) (21 years ago, 5-Jun-03, to lugnet.technic)

| (...) Thanks. (...) Correct. (...) Right ;^) (...) Yes, you can reverse the engine on the fly. It doesn't take much to make the engine not run. It takes a quarter turn of the case to get from ideal forward to ideal backward. (...) Kevin (21 years ago, 5-Jun-03, to lugnet.technic, lugnet.robotics, lugnet.build)

| (...) Wow! I saw your first reversible engine and I kind of got lost in all of the tubing. Needless to say, it was quite an accomplishment. Its amazing how far you have been able to take the analogy between pneumatics and electronics. But, I kept (...) (21 years ago, 5-Jun-03, to lugnet.technic, lugnet.robotics, lugnet.build)

| (...) Wow, that's a great design for a reversible and variable speed pneumatic engine. An ingenious use of the differential gear, too. And not to fret about correctness of the explanation. If it works, it must be correct ;-) (21 years ago, 5-Jun-03, to lugnet.technic, lugnet.robotics, lugnet.build)
